RDA 600-800 C

D Never work under the drill during maintenance or service work unless it has been properly se-cured with trestles or other strong supports on firm ground. Block each lifting ram (3 pcs) withthe correct yellow-coloured locking device. Please refer to the section “5.1 Securing the drillfor servicing” on page 67.

E Pay attention to the rotating transmission to the hydraulic pump. Do not stride across or stayclose to the rotating parts. Disconnect the transmission, switch off the ignition of the tractorand take out the key from the ignition whenever work close to the hydraulic pump or othermaintenance work is required. Do not use the protective cone as a stepping board. Make surethe protective cone is securely attached to the hydraulic pump. If the protective cone is dam-aged, be sure to replace it immediately. Always secure the hydraulic pump to the top rod mounton the tractor. Also see “3.2.3 Connecting the hydraulic pump for the fertilizer fan” on page 16.

F Watch out for you feet. Risk of pinching. When switching the machine between the work andtransport positions, it may sink a little when the valve is reversed. See “3.4 Switching betweentransport and work mode” on page 18.

G Always make sure the work area of the bout markers is free! Keep in mind that there is a riskof injury when the markers are folded down and there is a risk of crushing between the seeddrill and the markers when they are folded up!NOTE! The bout markers are always folded up when raising the machine no matter what is in-dicated on the Control Station. Switch off the Control Station when the machine is not opera-ting in the field. The Control Station stores all settings and values when it is switched off.

H Do not climb on the wheels when the drill is parked since they could rotate.

I Nobody must be on board the drill while driving. Do not stand on the seed hopper grating sincethere is a risk of falling down.Warning! The grating may become very slippery, e.g. when using talcum in connection withsowing of peas.

J Nobody must be on board the drill when loading seed.

K Transport height warning, especially for the RDA 800. See “7.4 Technical data” on page 104,Transport height.Warning for suspended cables, overpasses, gates, trees, etc. Always check the height clearancebefore driving through.

L Warning for piercing oil jet; the hydraulic system contains accumulators. Prior to any serviceor maintenance work on the hydraulic system, always be sure to drain the accumulators of alloil. See “5.11 Draining the hydraulic system accumulator” on page 75.

M Warning for pinching hands and arm when the front of the platform is raised and lowered.Warning for pinching the hands and arm between the top grating and the seed hopper.

N Warning for rotating transport screw. If the fertilizer screw needs cleaning and/or must bepulled out of the seed hopper, the tractor must first be stopped, switched off and the key re-moved from the ignition.

O Warning for rotating transport screw. Do not enter the fertilizer hopper and seed hopper unlessthe tractor has been stopped, switched off and the key removed from the ignition.

Safety precautions

1.3 Other safety precautions! Never leave the tractor with a hitched drill unattended unless the motor has been switched off

and the start key removed from the ignition.

Figure 1.3

! Never stand between a reversing tractor and the drill.

! Keep the platform on the left side of the machine clean to prevent slipping. Please note that therear part of the platform folds up against the seed hopper when the wing sections are retracted.

! Observe the greatest caution when transporting the drill on public roads. Please note that trafficlaws in many countries prescribe that the unbraked gross weight of the drill may not exceedthe gross weight of the tractor when traveling on public roads. As a result, in many cases it isprohibited to travel with a filled seed hopper on such roads.The rearview is very limited. Be sure to correctly adjust the tractor’s rearview mirrors.The owner/driver has sole responsibility when driving with the drill on public roads.

! This machine/implement and the fitted tyres are dimensioned for a maximum speed of 30 km/hon good country roads.

! For all servicing and repair work on the hydraulic system, the side sections must be in the fold-ed down position and the drill must be lowered and resting on level ground.

! Prior to servicing or repair work on the hydraulic weight transfer system, be sure to drain theaccumulators of all oil! See “5.11 Draining the hydraulic system accumulator” on page 75.

! Always park the drill on a level and firm surface. Be sure to set the master cylinder stopper insuch a way that the drill rests on both the wheels and the discs when parked.

! Always make sure the drill’s male connectors and the tractor’s female connectors are cleanand free of any contamination prior to connecting the drill.

! To maintain the high level of quality and operational safety of the drill, use only Väderstad gen-uine spare parts. The warranty and any complaint commitments will become void if other thangenuine parts are used.

! Any welding work on the machine/implement should hold professional standard.Please note that incorrect welding could result in serious or even fatal injuries.If in doubt, please consult a certified welder for correct welding instructions.

2 Assembly instructionsThe drill is delivered fully assembled. However, the Control Station needs to be installed in thetractor cab.

2.1 Installing the Control Station in the tractor

Be sure to install the Control Station securely in the tractor cab. Place it within the field of visionwhile looking in the travelling direction. Install the bracket as shown in the figure.

NOTE! Prior to any drilling in the tractor cab, be sure to check possible concealed wiring.

Connect the cables as follows: brown to plus (+) and blue to earth (–).

NOTE! Do not mix up the poles! If the tractor is fitted with a power outlet in the cab, use thisoutlet. If a power outlet is not available, an extra cable must be prepared. Preferable use a 6 mm²cable dimension. Do not use cigarette lighter sockets, since current consumption may reach 20A. It is important than the connection is correctly established, since any looseness could cause in-termittent operation.

Make sure the connection cable to the drill is not pinched under the rear window of the tractor,since this could easily damage the cable. Use the designated connector port or cable hole. Use sta-ples to securely fix the cable in the tractor cab. This protects the Control Station from damage incase the connection cable has not been disconnected prior to unhitching the drill.

Ver.1.2 04/03/02 13

Instructions and adjustments

3 Instructions and adjustmentsNOTE! Perform all basic adjustments with the drill hitched to the tractor, the side section foldeddown and the entire machine parked on a level surface.

3.1 Tractor

To avoid harmful soil compaction, the tractor should be fitted with extra wide tyres, for exampleby mounting twin wheels or similar. Reduce the tyre pressure as much as possible. Remove anyfront weights from the tractor.

Three double-acting hydraulic couplings and a separate depressurized return entry are required.The return entry should be mounted in accordance with the instructions of the tractor manufactur-er. A female coupling is supplied with the drill.

If the drill is fitted with twin hydraulic systems for adjusting the pre-implements, a fourth double-acting hydraulic coupling is required.

Figure 3.1 Figure 3.2

14 Ver.1.2 04/03/02

RDA 600-800 C

3.2 Hitching the drill

Figure 3.3

Hitch the drill to the tractor. The towing eyelet of the drill can be reversed for connection to a hitchtow hook or an agricultural draw-bar hook.

3.2.1 Connecting the hydraulic hoses for operating the machine

The two thick 3/8" hoses marked with yellow plastic rings are used for raising and lowering thedrill and operating the bout markers. The two thinner 1/4" hoses marked with white plastic ringsare used for folding down the side sections and adjusting any pre-implements. If the drill has twinhydraulic systems for adjusting the pre-implements, two additional 1/4" hoses are provided. Theseare marked with blue plastic rings.Carefully check that all hoses are connected in pairs to the correct hydraulic couplings on the tractor.

3.2.2 Connecting the hoses to a hydraulic seed output fan

Connect the two thin hoses marked with red plastic rings to a double-acting hydraulic couplingintended for continuous operation of a hydraulic motor. If available, use a coupling with higherpriority. The thicker hose of the two is the pressure hose, while the thinner hose is used for drain-ing oil. Connect the thickest hose, i.e. the 3/4" return hose, to a separate depressurized return entry.

NOTE! Lock the quick female connector on the return entry. See “Figure 3.5”.

NOTE! Carefully dry all couplings and connectors! This is to prevent unnecessary interruptionsand wear on the hydraulic system.

Before starting up the fan, please read the section “3.17 Setting the air quantity” on page 36.

3.2.3 Connecting the hydraulic pump for the fertilizer fan

NOTE! Do not start the PTO pump until the tractor’s hydraulic couplings for driving the seed out-put and seed output fan have been switched on.

NOTE! Pay attention to the dangers in the immediate vicinity of the transmission axle. See itemE in the section “1.2 Warning labels” on page 8.

Connect the hydraulic pump as explained below. Items 3 and 4 should only be performed duringinitial installation or when the pump is moved from one tractor to another.

1 Install the hydraulic pump on the tractor’s 1000 rpm PTO shaft. Ensure that the connector locksonto the PTO pin.

2 Install the top rod in the top rod mount of the tractor. Please note that two mounting points areused.

3 Install the hydraulic pump onto the top rod. Select the most suitable position between A andB. Do not tighten the screws. Suspend the pump allowing it to lean slightly upwards, approx.5° from horizontal. Secure the rod C with the bolts.

4 Let go of the hydraulic pump and tighten the four bolts D.Verify that the pump is horizontally suspended and does not incline upwards.

5 Clamp the top rod to eliminate any lateral play. If necessary, use the enclosed spacers betweenthe rod and the top rod mount. Lock the bolt with the locking nut on the outside.

Figure 3.10

Also see the section “3.17.2 PTO driven fertilizer fan” on page 37.

3.3 Adjusting the hose length and connecting the cables to the Control Station and lighting

Figure 3.11

Pull the hoses for the fans through the two hooks under the adjustable hose holder.

Run the other hoses through the adjustable hose holder. Fasten the hydraulic hoses in the smallholes in the hose holder and, prior to tightening the butterfly nuts, adjust the hose length as desiredby adjusting the loop sizes.

When this work has been completed, push the quick connectors into the upper large holes in thehose holder. Hoses used for raising the drill should be pushed into the holes marked with an arrowpointing up, while hoses used for lowering the drill should be connected to the holes marked withan arrow pointing down.

Connect the four-pole male connector from the drill’s electric system to the female connector onthe Control Station cable. Be very careful when making this connection. Make sure that the pinsof both connectors are aligned. Then lightly press the connectors together while securing the con-nectors with the nut.

Connect the male connector of the drill’s lighting connector to the standard outside electric outleton the tractor.

Ver.1.2 04/03/02 17


3.4 Switching between transport and work mode

3.4.1 Switching between transport and work mode

A Use the lifting system to completely press out the side section wheels.

Figure 3.12

B Quickly turn the ball valve from position 1 to position 2, and then screw in the needle valveuntil it touches bottom.

Warning! Do not keep your feet under the pre-implements since the machine may sink slightly.

Figure 3.13

C Raise the drill to the topmost position. NOTE! The centre section should always have beencompletely raised prior to folding down or folding up the side sections.

Figure 3.14

D Pull together the side sections using the folding ram. NOTE! Do not operate the folding ram inthe wrong direction during this procedure. Watch the short piston rod end, which should re-main in its outermost position. Lock the side sections in place using the operating line from thetractor cab. Keep the line taut until both side sections start to fold down.

18 Ver.1.2 04/03/02

RDA 600-800 C

E Fold down the side sections of the drill while the machine is driven slowly forward. Continueholding the hydraulic lever engaged until the folding ram has been completely extended andthe piston rod of the weight transfer ram is extended approximately half way.

F Always drive in the forward direction when lowering the drill to its work position in the field.This prevents clogging of the seed boxes.

3.4.2 Switching between work and transport mode

A Switch off the low-lift mode on the Control Station. Raise the drill to the topmost position.NOTE! The centre section should always have been completely raised prior to folding down orfolding up the side sections.

B Fold up the drill and check whether the wing locks engage.

C Quickly turn the ball valve from position 2 to position 1, and then completely screw out theneedle valve.Warning! Do not keep your feet under the pre-implements since the machine may sink slightly.

D Retract the side section wheels with the lifting system. Do not retract the wheels more than un-til they are slightly inside the transport width of the drill. If the wheels are retracted any further,the machine could become damaged.

E Check whether the pre-implements and following implements are within the 3 m transportwidth.

Ver.1.2 04/03/02 19


3.5 Ground parallelism

Figure 3.17

Longitudinal inclination of the drill has been preadjusted at the factory. Adjustment is only nec-essary if the push rod at the rear end of seed hopper is disassembled. Adjust the push rod lengthby turning the nut (A) until the outer side plates (B) are parallel with the ground when the drill israised and with the discs kept a few centimetres above ground.

Also verify ground parallelism by making sure the front seed coulters drill to the same depth asthose at the rear.This can be easily verified using the Väderstad drill depth meter. First pack the soil a bit, thenscrape off thin layers of soil until the grains become visible. Grains in all rows should be visibleat the same time. If this is not the case, the drill is not operating in a parallel state.

Figure 3.18

To relieve the push rod of pressure during this adjustment, it is necessary to press down the pre-implements fully.

NOTE! This incurs the risk of the coulters blocking!

20 Ver.1.2 04/03/02

RDA 600-800 C

3.6 Weight transfer setting

The weight transfer should usually be set to 30-50 bars. This pressure will be satisfactory in mostcases and normally does not require any adjustment. The pressure can be verified using the ma-nometer next to the folding ram on the rear end of the drill when the drill is folded down on levelsurface.

If the drilling depths of the centre and side sections differ, first check the settings of the three lift-ing rams. If the drilling depths are still different due to different loads on the three sections, thenadjust the pressure. Proceed as follows to change the hydraulic pressure of the weight transfer sys-tem:

A Raise the machine to the topmost position.

B Open the ball valve of the weight transfer accumulator to position 2.

C Operate the folding down hydraulics for a few seconds until the folding ram is completely ex-tended and the weight transfer ram is in the halfway position (i.e. C = 30 mm).

D Switch off the tractor.

E Close the ball valve to position 1.

F Engage the floating position of the tractor hydraulic couplings.

G Carefully open the ball valve while checking the manometer. Close the valve when the desiredpressure is reached.

H Check whether the weight transfer ram still remains in the halfway position (i.e. C = 30 mm).

An increase in the manometer pressure results in increased pressure on the side sections.

3.7 Adjusting the reversing valve

Figure 3.20

This valve is normally preadjusted at the factory. The reversing valve (A) switches the operationbetween folding down the side sections and operating the pre-implements. When the drill has beenlowered to the work position, one of the tractor’s double-acting hydraulic couplings is connectedto the pre-implements, while when the drill is raised onto its wheels, the same hydraulic couplingthen is connected to the folding the side sections.

The lever (B) must always remain in its end position when the drill is in the transport or workmode. This is adjusted by pushing the valve (A) forward or pulling it backward in its bracket. Fol-lowing this adjustment, tighten the valve bracket screws (C) to prevent the valve from sliding inthe tracks.

22 Ver.1.2 04/03/02

RDA 600-800 C

3.8 Adjusting the pre-implements

Figure 3.21

The pre-implements are normally preadjusted at the factory.

Similar to the lifting system, the pre-implements are also connected to a master and slave system.The system is operated over the same hydraulic coupling used for folding the side sections. Thepre-implements can only be operated when the machine has been lowered to the work position.Also see “3.7 Adjusting the reversing valve” on page 22.

Prior to adjustment of the pre-implements, the hydraulic system must be bled and reset just likethe lifting system. See “3.12 Setting the drilling depth” on page 26. Bleeding the system shouldbe done with the drill in the work position and the pre-implements completely raised to enable thehydraulic rams to extend fully to the outermost positions.

Then verify the basic adjustment of the pre-implements while hitched to the tractor and the drillfolded out, resting on the seed coulters on level ground. If necessary, adjust the piston rods (A) toachieve the same work angle on all pre-implements. Loosen the counter-nut (B) while turning thepiston rod and the hydraulic ram in place. The piston rods can be adjusted to a maximum threadextension (C) of 20 mm.

Fine adjustment is then performed in the field by adjusting the piston rods (A) until all sectionswork at the same depth. Adjust the angle and depth of the front pre-implements in relation to therear implements using the hole series in the parallel adjusting devices (D).

An optional separate hydraulic system can be ordered for adjusting the front row of tines. See“Figure 3.22”.

3.9 Adjusting the following harrow

Figure 3.23

1 Select a suitable work angle from hole series B.

2 The work pressure of the following harrow is adjusted using the adjusting screw (A). Depend-ing on the work pressure set on the following harrow, the cotter (C) should be positioned be-tween the trailing edge and centre of the oblong groove (D).Adjust the following harrow to remain in the work position when turning on the headland inthe low-lift position. This will cancel out the tracks of the drill when turning.

Figure 3.24

This indicates that the following harrow tines travel in thefurrow centre. When the following harrow tines travel between the furrows, high pressure canbe applied on the following harrow without disrupting the seed. In this fashion, a vaporiza-tion layer can be harrowed while sowing.

NOTE! Do not reverse the tractor unless the drill has been fully raised and the following harrowhas sufficient clearance height.

3.10 Setting the low-lift height

The low-lift height can be adjusted by screwing the magnet switch up or down in its bracket withthe help of the wing screw (A), which is subsequently locked with the butterfly nut (B). NOTE!Do not forget to tighten the butterfly nut B following this adjustment! Never screw out thewing screw so much as to create a distance between the screw end and the plate at position (C)when the machine is in the work position or low-lift position.

NOTE! Be very careful when making this adjustment. The low-lift height should not be set toohigh or low.

! Too high a setting would cause the pressure on the following harrow to become too low on theheadland (of course when this is not desired).

! The low-lift height should be set so that the distance between the drill discs and the ground isat least approx. 60 mm. If the height is less, there is a chance that the magnet switch could beengaged while drilling, thus shutting off seed output during short intervals (an alarm is not dis-played on the Control Station).Too low a setting could also cause incorrect operation of the auto advancing of the Control Sta-tion and result in inability to sufficiently lift the pre-implement and discs off the ground.

Also see “3.22.2 Functions” on page 56.

3.11 Scraper

Figure 3.27

The scraper position can be adjusted in two places. If the adjustment range of the scraper blade(A) is insufficient, the holder (B) can be adjusted lengthwise.

NOTE! The distance between the point of the scraper blade and the tyre may never be less than5 mm. Otherwise the scraper and tyre could become damaged!Do mount the holder so that the scraper mounting nut comes too close to the tyre, causing unnec-essary wear.

Following mounting of the scraper, if it is not correctly adjusted in the lateral position, the holdershould be aligned with suitable tools.

3.12 Setting the drilling depth

3.12.1 Adjusting the master and slave system

Figure 3.28

The drilling depth of the drill is controlled by three hydraulic rams connected in series in a masterand slave system. Prior to using the drill, proceed as follows to bleed and reset the rams in relationto each other:

Raise the drill to the topmost position allowing all hydraulic rams to extend fully. Keep the hy-draulic lever in this position while running the tractor at half revolutions for about 15-20 seconds.At the top position, the rams feature an overspill facility that allows the oil to flow through thesystem and bleed the system of any air. Repeat the procedure for a couple of seconds after hitch-ing the drill to the tractor, prior to adjusting the drill, after the drill has been folded down, and acouple of times throughout the workday.

After the master and slave system has been bled and reset, the drilling depth of the three sectionscan be adjusted. This adjustment is made with the drill in the work position in the field. Checkwhether the folding ram is fully extended and that the hydraulic pressure in the weight transfersystem is normal, i.e. 30-50 bars. Set a suitable drilling depth using the aluminium stopper on themaster ram piston rod on the centre section. See position A. Drive forward and lower the drill.Keep the hydraulic lever in position for a few seconds, e.g., while the bout markers are foldeddown.

Verify the drilling depth in the centre of each section. See “4.1 Drilling depth” on page 64. If nec-essary, adjust the piston rod length on each section. Usually, the master cylinder piston rod shouldbe kept approx. 10 mm extended, and instead the slave ram piston rods on the side sections areadjusted. See position B below. This adjustment should be done so that none of the piston rod endscome lose from the machine.

A Loosen the counter-nut (C).

B Turn the piston rod (B) by its key handle by hand so that the piston rod end extends or retracts.The drilling depth becomes more shallow as the piston rod extends. NOTE! At the end stopsof the hydraulic rams, it may be difficult to turn the piston rod! Do not adjust the piston rodends more than the specifications allow.

C Loosen the counter-nut (C) towards the piston rod (B).

3.12.2 Setting the drilling depth, seed

Once the master and slave system has been adjusted, the drilling depth can be easily adjusted bysimply moving the stop bolt (A) on the master ram. The scale indications do not constitute abso-lute values of the drilling depth in centimetres, but serve as an index only. Reset and bleed the sys-tem for about 5 seconds a couple of times throughout the work day. Also see “4.1 Drilling depth”on page 64.

3.12.3 Setting the drilling depth, fertilizer

The drilling depth of the fertilizer boxes is set using the three cranks on the front of the ram sec-tions. One of the cranks is placed on then left side of the machine, while the other two can be foundon the right side. Fold out the cranks in the rotational direction as shown in the figure.

For combination drilling, the drilling depth of the fertilizer boxes is usually set slightly deeper thanthat of the seed boxes.

Check whether the drilling depth of all sections is the same.

When only drilling seed, the fertilizer boxes can be set to a suitable drilling depth to cultivate thesoil or they can be completely raised.


Ver.1.2 04/03/02 27


3.13 Adjusting the seed coulters

NOTE! The drill must be properly secured prior to performing any work under it. See “5.1 Secur-ing the drill for servicing” on page 67.

To ensure a satisfactory sowing result, it is important that the seed boxes are correctly installed onthe drill. Determine the installation height with regard to the conditions and the wear of the disc.When the drill has been lowered with the discs resting on firm ground, the seed boxes should notreach the surface, (c > 0 mm). For sowing without ploughing in ground rich with straw litter aswell as for sowing in light soils, too low an installation may cause the discs to stop rotating. Ifinstalled too high, seed placement may be impaired.

The seed boxes are suspended on two bolts. Using the soft washers, the boxes are pressed tighteragainst the discs as the nuts are tightened. Do not tighten the nuts more than the boxes can be easilytilted with one hand. The box must not have too close contact with the disc, since this will causeincreased wear and rotational friction.

For very loose soil and/or shallow drilling depths, it may be necessary to slightly loosen the nuts.

Before replacing the seed boxes, it is recommended to wash the drill clean. When new seed boxesare mounted, it is necessary to check the width of the slot between the disc and the box. The slotshould be wider at the top. Unless this is the case, straw plant residue may collect here. If the seedboxes do not make contact at the correct place, this can be adjusted by adjusting the metal platesat positions A and B or outside the fastening iron. The point of contact can also be slightly movedby tightening the front nut more than the rear one.

The platform of the machine consists of two sections. The rear part is folded up when the wingsare raised to the transport position. The front part of the platform can also be raised to facilitate,e.g., calibration and service. It is recommended to lift the platform by holding the ladder. Theplatform can be locked in the raised position by hooking the sliding rail onto the bolt as shown in“Figure 3.33”.

NOTE! Pay attention to the risk of pinching between the front and rear part of the platform!

NOTE! Risk of slipping! Keep the platform clean at all times. Do not allow anyone to be on theplatform while driving or loading seed. The platform ladder is not designed for manual loading ofsmall bags. Also see “3.19 Filling the seed hopper” on page 40.

3.15 Seed hopper upper grating

The seed hopper has an upper grating, divided into three section. Always ensure that the safetystoppers (A) of the gratings engage properly when the gratings are lifted up. To unlock, lift thestoppers and then lower the grating

NOTE! Pay attention to risk of pinching between the upper grating and the seed hopper.

NOTE! Fertilizer screw at bottom of seed hopper. Do not enter the fertilizer hopper unless thetractor has been stopped, switched off and the key removed from the ignition.

3.16 Output system, overview

3.16.1 Seed output system

Seed is fed out via two seed boxes using a hydraulic cellular wheel feed output system. Seed istransported by pneumatic means to the seed boxes. The amount of seed that is fed out can be de-termined by adjusting the cellular wheel engagement and the rotational speed. The seed output fanis placed at the front of the seed hopper.

3.16.2 Fertilizer system

Output of fertilizer is done by means of a hydraulically driven screw transport device at the bottomof the seed hopper. The screw feeds the fertilizer in an air spiral for delivery to the fertilizer boxes.The output fertilizer amount can be determined by adjusting the rotational speed of the screw. Thefertilizer output fan is placed at the rear of the seed hopper.

3.16.3 Using the seed hoppers

Usually, the front seed hopper is used for seed, while the rear hopper is used for fertilizer.

It is also possible to use both seed hoppers for seed. In this case the rotational speed of the fertilizerscrew should be adjusted to allow automatic transport of seed to the front hopper. Please note thatthis requires reprogramming of the Control Station and a special adjustment of the hydraulic valves.See “3.16.7 Calibration adjustments prior to drilling with seed in both hoppers:” on page 35 and“3.22.3 Programming” on page 59.

3.17.2 PTO driven fertilizer fan

NOTE! Do not start the PTO pump until the tractor’s hydraulic couplings for driving the seed out-put and seed output fan have been switched on.

The fertilizer fan is situated on the rear gable of the seed hopper and is driven by a hydraulic pumpconnected to the tractor’s PTO shaft.The hydraulic pump is designed to be driven at a PTO speed of 1000 rpm.

The amount of air can be adjusted using the fan rpm. It is set from the Control Station.The fan rpm can be adjusted using a valve (E) on the hydraulic block next to the front gable of theseed hopper. The rpm increases when the crank is turned in (+), while it decreases when the crankis turned out (–).The fan rpm can also be adjusted by altering the tractor rpm. However, the PTO shaft revolutionsmay never exceed 1000 rpm.

Figure 3.40

Use the fan rpm as indicated in “Table 3.2”. Please note that the fan rpm should be adapted to theoutput amount when using Urea.

The low rpm alarm on the Control Station should ideally be programmed to 300 rpm below theset rpm, while the high rpm alarm should be set 300 rpm above the set rpm. See “3.22.3 Program-ming” on page 59.

NOTE! During operation, the oil temperature may become very high (above 80°C).

Before starting:! Check that no cables or bolts are loose.

! Check whether the pump and its bracket are correctly installed. See “3.2.3 Connecting the hy-draulic pump for the fertilizer fan” on page 16.

! Check that all hoses are free from damage and properly suspended.

Normal start-up:Always start the pump with the tractor at idle and let it run for a while to allow all hoses, the pumpand motor to warm up. Do not start the fan while the tractor is at operating speed. In this case cold,viscous oil and pressure peaks will shorten the service life of the system.

3.22.2 Functions

Auto advanceThe Control Station usually operates with so-called auto advance. This means that the furrows inthe tramlining cycle are advanced and the bout makers are switched at the completion of each fur-

row. The auto advance feature can be blocked by depressing push-button . When auto ad-vance is blocked, the indicator lamp in the push-button lights.

Bout markers

During normal driving, automatic bout marker switching is used. Press until the green in-dicator lamp lights. To advance a bout marker, depress the push-button once again.

Use the push-button for manual selection of bout markers. Selection is possible betweenboth bout markers folded in, left bout marker in, right bout marker in, and both bout markers foldedout.

Low-lift/Full lift

Use the push-button to switch between low-lift and full lift. The indicator lamps next tothe push-button show which function has been engaged. Use low-lift when drilling. This preventsthe machine from being raised too much, while allowing proper operation of the following harrowin the headland. Never reverse the machine in the low-lift position.

If it becomes necessary to raise the machine, e.g., when encountering an obstruction in the furrow

or to turn back and fill the seed hopper, be sure to first press to disengage the auto advance

feature. Then press to switch to full lift. The machine can now be raised to its maximumheight.

When the drill later is returned to the same position as before the interruption, press to re-

engage auto advance of tramlining and bout marker switching, and press to return to low-lift operation.

The indicator lamp on the left of the push-button blinks when the low-lift switch has been en-gaged.

Lift stopUse the lift stop when the bout markers should be retracted without lifting the machine from work,

e.g., to pass a post or well. Press the push-button and lift the bout marker using the hydrau-

lic lever. Use to alternate between low-lift and full lift. The Control Station remembers thefunction that was engaged prior to activating the lift stop.

Drilling tips

4 Drilling tips

4.1 Drilling depth

Figure 4.1

See “3.12 Setting the drilling depth” on page 26.

Probably the most important task the Rapid operator needs to attend to is to carefully monitor thedrilling depth. The drilling depth is set by operating the lifting ram stopper. The scale indicationsdo not constitute absolute values of the drilling depth in centimetres, but serve as an index only.

Rapid drills can be used under a great variety of conditions, from “direct drilling” to sowingstraight after the plough. This versatility is made possible by the drill’s coulter system design andits unique depth control system, amongst other features.

The drilling depth should conform to the crop, soil type and the conditions when drilling. Shallowsowing calls for very good conditions for germination in terms of moisture and fine tilth, for ex-ample in silty soils. Drilling too deep may result in weaker plants.

In fields with varying soil types, the depth setting should be checked and adjusted to ensure thecorrect drilling depth across the entire field.

The drilling depth must be adjusted so that the seed is placed in moist soil, but not too deep. Cor-rect preparation of the tilth prior to drilling will be decisive in determining the right conditions forgermination.

The drilling depth should be checked regularly throughout the day. Preferably this should be doneonce every hour. Check the drilling depth in the centre between the tractor wheel tracks, in onetractor wheel track, behind the right side section and behind the left side section. If the drillingdepth of the side sections deviates from that of the centre section, the function and settings of thehydraulic system function need to be checked. See “3.12 Setting the drilling depth” on page 26and “3.6 Weight transfer setting” on page 21. This applies, among others, to the weight transferto the side sections. When working on hard soil, the pre-implement may require a larger amountof weight transfer. When sowing small-size seed on loose soil, it may be necessary to reduce theamount of weight transfer.

Also check at the same regular intervals that the stopper for the drilling depth setting has notmoved. If the position of the stopper has changed, it is usually not sufficient to simply tighten itmore. The stopper should only be moderately tightened. See “3.12 Setting the drilling depth” onpage 26.

64 Ver.1.2 04/03/02

RDA 600-800 C

4.2 Seed output control

Figure 4.2

While checking the drilling depth, i.e. once every hour, seed output should also be verified.

When verifying the seed output, also check that both sides of the machine feed the same amountof seed from each seed box. Raise the machine to the low-lift position. Then engage the full-liftposition.

Start the fans. Keep on the Control Station depressed for a few seconds. Exit the tractor andcheck whether seed output is working. Repeat the procedure if there is any doubt about seed outputfrom the machine.

Start from the tramlining position, when all coulters, except those shut for tramlining, are sup-posed to output seed. Then advance the tramlining function and check to see if these boxes deliverseed now.

If the two sides output different amounts of seed, first check whether one of the seed units is dam-aged. If this is not the case, the seed units should be set to different scale values to achieve thesame seed output rate on both sides.

Ver.1.2 04/03/02 65

Drilling tips

Figure 4.3

Verify whether the seed output level falls at the same rate in both inspection windows.

Make it a habit to make a quick visual check of the claw couplings between the fertilizer screwand hydraulic motor and between the seed output hopper and hydraulic motor to ensure they arein place and appear normal.

At regular intervals, ensure that the seed box rollers rotate at uniform speed.

This sowing system has been developed to deliver uniform seed output and reliable quantities.Väderstad-Verken AB shall not be liable for any claims for indirect or consequential damages re-lating to losses incurred in connection with the use of the drill. Väderstad-Verken AB accepts noliability for losses arising from incorrect use of the drill, including sowing and seed dosage errors.

It is the responsibility of the user to use seed, which has been treated correctly with an additive ofa type that does not impair the functioning of the seed output mechanism. Please note that the useof seed, which is larger than normal pea seed size can damage the sowing mechanism.

5 Maintenance and service

5.1 Securing the drill for servicing

NOTE! For any work under the drill or when there is danger of pinching, the drill must always besafely supported on trestles or similar.

Secure the drill with trestle, etc. and block all lifting rams with the yellow-coloured locking devices!

There are three lifting rams for the depth setting of the drill. Raise the machine to the topmost po-sition and push the stopper on the master ram towards the ram gable prior to setting the stoppingdevice in place.When the machine is folded up, the two slave rams need not be blocked, however check whetherthe locking devices on the side sections have engaged properly.

The surface under the trestles must have sufficient strength. If the seed hopper is filled, whichshould be avoided when servicing the drill, the weight of the machine is considerable.

Service on the hydraulic system should always be made with the wings lowered and the drill rest-ing on the ground!

Figure 5.1 Figure 5.2 Figure 5.3

Ver.1.2 04/03/02 67

Maintenance and service

5.2 General

Figure 5.4

! The machine will only perform at its best when properly serviced!

! Before using the machine, check that all nuts and bolts are tight. During the season, check pe-riodically that the nuts and bolts have not worked loose and inspect joints and hydraulic rammountings for wear.

! Do no tighten bolts in flexible joints too tight, since the moving parts then become pinched.

! The hydraulic system normally does not require any maintenance, but be sure to check thathoses and couplings have not been damaged.

! Be sure to keep dirt away whenever work is required on the hydraulic system! Use clean paperor clean rags to clean the area. Put all component on a clean surface and not directly on thework bench. Prior to refitting, flush with a degreasing agent.

! Grease or oil the piston rods if the drill is not going to be used for a long period of time andalways after cleaning it.

! Lubricate galvanised and chrome-plated surfaces with grease before long periods of storage.

! To preserve and maintain the high quality of the drill, only use Väderstad genuine spare parts.

68 Ver.1.2 04/03/02

RDA 600-800 C

5.3 Cleaning

Regularly check that seeds, fertilizer or wrapping has not got stuck in the drilling hoses or the drillhead outputs. Also perform this check at the end of every season. At the same time, verify that thetramlining units are clean and operate correctly.

Clean the seed hopper, the fertilizer screw, the rape brushes, the seed units and other parts at theend of the season. Check whether seed or fertilizer has entered the ejector pipes and connected airhoses.

Keep in mind that any seed sprouts that remain in he machine easily cause blocking of air pipesand drill hoses. The seed also attracts rodents that could cause additional damage to the drill.

Clean all glass surfaces on the drill heads prior to each season.

Let the fan run for a while to completely dry out the system.

5.3.1 Seed feed unit and rape brushes

The seed boxes should be cleaned inside and checked at regular intervals for wear on plastic andrubber parts. It is especially important to make sure pesticides have not built up in the buckets witha resultant decrease in volume.

The scale cover has a drain in the bottom and can be flushed once the seed unit has been turnedclose to zero.

If necessary, also clean inside the transparent transmission cover.

Check that the cell wheel flaps do not jam and that they are aligned with the bottom of the trackfrom zero setting and up.

Check all cabling.

Rape brushesWhen setting the drill for drilling oil-yielding plants, the rape brushes should always be inspectedand if necessary cleaned. Check whether the brush rotates easily on the shaft. Do not grease therape brush.



Ver.1.2 04/03/02 69


5.3.2 Disassembling the fertilizer screw

If the fertilizer screw needs cleaning and/or must be pulled out of the seed hopper, the tractor mustfirst be stopped, switched off and the key removed from the ignition.

Figure 5.10

If the fertilizer screw needs cleaning, this can be easily done by disengaging its hydraulic motorand lowering it, and then pulling out the screw in the forward direction.

Figure 5.11

The end plate of the screw has two guides that must be lined up with the corresponding notcheswhen reassembling the screw. Also be sure that the claw coupling of the motor is aligned withclaw coupling of the screw.

70 Ver.1.2 04/03/02

RDA 600-800 C

5.4 Long-term storage of the drill

Figure 5.12

When not in use, the drill should be kept indoors. This is especially important because the drill isequipped with electronic instruments. The electronic components are of very high quality andwhile they are able to resist humidity, it is nevertheless advisable to keep the drill indoors. TheControl Station should be kept at room temperature over the winter and in between seasons.

Mirror-finished drill parts, such as piston rods and wearing parts, should be greased prior to long-term storage over the winter.

Ensure that the drill is properly cleaned. Allow the discharge doors to remain open and disconnectthe air hose from the ejector pipe to facilitate air ventilation.

Prior to folding down the drill in cold weather, it must be parked in a heated building to allow thedrill hoses to regain their softness.

Ver.1.2 04/03/02 71


5.5 Lubrication pointsAlways by safety conscious and never go under the drill. When lubrication is required, only lubri-cate from the top or safely secure the drill with trestles prior to any such work. See “1 Safety pre-cautions” on page 8.

Regularly lubricate the drill as follows: disc bearings should be lubricated until the grease pro-trudes; for other parts 2-3 piston strokes.

Lubrication charts with picture references are available in the spare parts list.

Lubricate all grease-cups according to the lubrication intervals and always after cleaning with ahigh-pressure jet.

Never flush water directly on a bearing! The seals and ball bearings could easily become damagedby the high-pressure jet since the water will penetrate the bearings and cause corrosion!

Always lubricate the drill after each season.

5.6 Disc replacementEnsure that the drill has been safely secured with trestles.

When replacing discs, use a ratchet spanner or preferably a nut runner. Turn the disc so that thecompletely flat side faces the seed box.

NOTE! Wear gloves - the discs have sharp edges!

Adjust the seed box if necessary. See “3.13 Adjusting the seed coulters” on page 28.

5.7 Replacing the disc bearings

The bearing has a ball bearing that is pressed onto the shaft pivot and locked in place with a clampring. To remove it, circlip pliers and a puller should be used. Special pullers can be ordered fromVäderstad-Verken AB: order no. 413549.

When replacing the bearing, grease the new sealing rings. Refer to the figure regarding how the seal-ing components should face. The bearing must have a tight fit on the shaft. Each bearing has a greasenipple that requires lubrication every 150th operating hour, always following cleaning with a high-pressure jet, and minimum once per season. Pump the grease in until it begins to come out.

5.8 Replacing the seed coulter mounting bolts

The disc arm has two recessed bolts that keep the seed coulter suspended. If the bolts cannot beknocked out, they should be cut and ground level with the arm. To facilitate this work, it may benecessary to disassemble the entire disc arm. The bolts can then be knocked out using a Ø13.5 mmmandrel. Once the old bolt has been driven out, there may burrs in the hole. Use a file to removethese and make it easier to fit the new bolt. The new bolt should be knocked or pressed into placeusing washers and a nut (not a locking nut). Properly lubricate the washers and the thread and low-er surface of the nut. Do not tighten the bolt with the nut. Use a sufficient amount of washers toavoid that the bolt touches bottom in the nut thread.

Regarding replacement and adjustment of the seed coulters, see“3.13 Adjusting the seed coulters”on page 28.



Ver.1.2 04/03/02 73


5.9 Replacing the seals of the hydraulic ram

Figure 5.18

NOTE! Prior to service of the hydraulic system, the side sections must have been folded downand the drill lowered to the ground. Also ensure that the hydraulic circuits are depressurized. Priorto service of the folding and weight transfer system, see “5.11 Draining the hydraulic system ac-cumulator” on page 75.

Completely disassemble the rams from the drill prior to replacing the seals.

When replacing the seals, the overspill channel or holes should be polished with an abrasive clothin the longitudinal direction of the ram. Carefully flush the ram prior to assembly.

NOTE! Check whether the seals are correctly mounted. If necessary, also replace the seals of thepiston rod guides (A).

Reassemble the ram onto the drill and bleed the master and slave system. See “3.12 Setting thedrilling depth” on page 26.

5.9.2 Replacing the seals on other rams

Proceed as outlined in “5.9.1 Replacing the ram seals on the master and slave rams” on page 74.Please note that these rams do not have any cuff seals nor overspill channels.

5.10 Replacing the master ram valve seals

Figure 5.19

A Carefully unscrew the guide (C) in case there is any remaining hydraulic pressure in the sys-tem.

B Replace the O-ring (A) and, if necessary, also the O-ring (B) in the guide. NOTE! The O-ring(A) is manufactured of a reinforced material.

C Reassemble the valve.

The valve on the bottom of the master ram closes the oil flow from the ram when lowering themachine and the set drilling depth has been achieved.

The drilling depth can be set using the stop bolt (A), which in turn actuates the valve rod (D) andthe valve. If the stop bolt on the piston rod is gradually disrupted, the drilling depth increases overtime, indicating that this valve is probably leaking.

5.11 Draining the hydraulic system accumulator

Figure 5.20

NOTE! Prior to commencing any work on the hydraulic system controlling folding movementsand the weight transfer system, the accumulator must be drained of all oil! When the hydraulicsystem accumulator is drained, the pressure indicated on the manometer will reach zero.

NOTE! When servicing and/or carrying out repairs on the hydraulic system, the drill must alwaysbe folded down beforehand!

A Open the weight transfer cock, turning it from position 1 to position 2.

B Raise the drill to the topmost position. Depressurize the folding system of the drill using thehydraulic lever. Check whether the pressure shown on the manometer reaches zero.

C Lower the drill once more.

For resetting the pressure, see “3.6 Weight transfer setting” on page 21.

5.12 Repairing and replacing drill hoses

Figure 5.21

RepairsIf a drill hose has been damaged as a result of wear or excessive bending, it can be spliced usinga sleeve (order no. 415397 for Ø32 mm drill hose dimensions). This dimension is the outer diam-eter of the sleeve and the inner diameter of the hose. Cut off the hose in the middle of the bend orthe damaged area. If unavoidable, cut off a short length of the hose. If the hose becomes too stiffat the splice joint and cannot be bent sufficiently when the drill is folded down, it may becomenecessary to replace the entire drill hose, or alternatively replace part of the hose and splice it intwo places.

Replacing drill hosesUse soap water on the hoses when removing and refitting the hoses on the seed box. When remov-ing and refitting, turn the hose counter-clockwise. This will slightly “open” the spiral-shaped hosereinforcement. Cut the replacement hose to the same length as the original hose.

Always replace wearing parts well in advance of the new season!Proper care of machinery is a presequisite for good machine economy!

Troubleshooting

6 Troubleshooting

6.1 General information on troubleshootingMany of the functions of the drill are controlled by a series of electric, hydraulic and mechanicalcomponents. A good way to exclude many of the sources of faults from the start is to first deter-mine whether the fault is electric. Because of this, first check whether the electric circuit is closedto the last electric component in the chain.

Then continue troubleshooting by first performing easy inspections, in order to quickly excludeother sources of error.

Carefully study the attachments “7.2 Hydraulic diagram” on page 92 and “7.3 Electric system”on page 98, which can be useful during troubleshooting. Also study the descriptions under “3.22Control station” on page 52.

6.1.1 Electric fault

General checks for electric faults:

! Is the Control Station properly connected to the tractor?

! Is at least 12 V reaching the Control Station from the tractor?

! Have the + (brown) and ground (blue) terminals been connected properly?

! Check whether the automatic fuse of the Control Station has tripped.

! Check the settings on the Control Station.

! Check whether both connectors of the intermediate cable are correctly connected to the ControlStation and Workstation.

! Check that the connectors and sleeves of all 4-pole switch connectors are clean, free from dam-age and are not depressed. Spray the connectors with contact spray, type 5.56.

! Check whether the intermediate cable is pinched or otherwise damaged.

6.1.2 Hydraulic fault

General checks for hydraulic faults:

! Check that the hydraulic hoses have been connected to the correct hydraulic couplings on thetractor. Hoses with the same colour coding constitute a pair.

! Make sure the hydraulic hoses’ quick couplings are dimensioned for and fit the couplings onthe tractor. A number of couplings are available in the market, however, although most arestandardized problems still exist. Problems that may appear could be that female and male cou-plings operate as non-return valves, i.e. the machine can be raised but not lowered or vice ver-sa. The problem may be aggravated by a high flow rate or worn couplings.

RDA 600-800 C

6.1.3 Hydraulic electric valves

Figure 6.25

An electric valve contains a coil that operates as an electromagnet when current is fed to the valve.Proceed as follows to check whether the valve receives current:The LED on the connector lights and the coil becomes warm after a few minutes. Also, the nut onthe top of the valve becomes magnetic.Use a small screwdriver or the edge of a knife blade to check whether the nut on top of the valveis magnetic. Since residual magnetism may be present in the nut, perform this inspection with thepower switched on and off.

! The bout marker valves (A) and (B) receive current when each indicator lamp on the ControlStation lights and the machine is operating in the low-lift mode.

! The lift stop valve (C) receives current when the lift stop is engaged or during lifts in the low-lift mode.

! The pre-emergence bout marker’s electric valve (D) receives current when the tramline indi-cator lamps on the Control Station light when the machine is in the low-lift mode.

NOTE! Signals to the bout markers and pre-emergence bout marker are not output from the Con-trol Station until the machine is set to the low-lift mode.

6.1.4 Magnetic switch

Figure 6.26

A reed switch is a switch (or a sensor) that reacts to a magnetic field. Inside the reed switch is aglass tube containing two metal reeds that attract to each other when subjected to a magnetic fieldfrom a magnet. See the figure. This can easily be tested using a multimeter and a magnet.

6.1.5 Inductive detector

Figure 6.27

These sensors trigger when metal objects pass within a distance of 1-1.5 mm.

A function test can be easily made since the sensor LED lights each time it senses an object.

6.1.6 Capacitive sensors

Figure 6.28

These react to matter containing humidity, such as corn, a hand, etc.

A function test can be easily made since the sensor LED lights each time it senses an object.

RDA 600-800 C

6.2 Troubleshooting chart

The Control Station does not operate when the main switch is switched on! - See “6.1.1 Electric fault” on page 78.

The bout marker(s) cannot be unfolded! - Check according to “6.1.1 Electric fault” on page 78.

- Check according to “6.1.2 Hydraulic fault” on page78.

- Check whether one of the bout marker indicator lampson the Control Station lights.

- Check whether the machine is in the low-lift mode.(For safety reasons, the bout markers cannot be un-folded in the low-lift mode or at a higher height.)

- Check the low-lift switch. Disconnect the switch con-nector from the Workstation and verify correct boutmarker operation.

- Check the wing unfolding switch. This switch blocksthe current signal from the bout marker valves whenthe wings of the drill are retracted. This prevents about marker from being unintentionally unfolded inthis position. Disconnect the switch connector fromthe Workstation and verify correct bout marker oper-ation.

- Check the current supply to the two electric valves (A)and (B) in the centre of the top surface of the valveblock. See “6.1.3 Hydraulic electric valves” on page79. The bout marker valve(s) should receive currentwhen the corresponding indicator lamp lights.

The bout marker(s) cannot be retracted! - This is probably caused by contamination in an elec-

tric valve. Please note that contamination that causesfaults such as this often is not visible to the naked eye.In this case, replacement of the electric valve is rec-ommended.

- It should always be possible to retract both bout mark-ers no matter which setting and indication are ob-served on the Control Station and also when theControl Station has been switched off.

Ver.1.2 04/03/02 81

Troubleshooting

Unintentional very slow unfold-ing of retracted bout marker(s)! - Check that the indicator lamp of the bout marker is not

lit on the Control Station.

- Check that the electric valve (A) or (B) of the boutmarker does not receive current. See “6.1.3 Hydraulicelectric valves” on page 79.

- Replace the electric valve of the right bout markerwith the electric valve of the left bout marker, andvice versa.If the fault then appears on the other side, it is causedby a defective electric valve.If the fault remains, it is likely that the hydraulic ramof the bout marker is defective.

- Disassemble the electric valve and check whether it iscontaminated and that the outer seals of the valve areintact and free from damage.NOTE! First lower the drill to the ground and depres-surize the system!

- Check that the bout marker ram does not leak on theoutside and inside. For seal replacement, see “5.9 Re-placing the seals of the hydraulic ram” on page 74.

Automatic switching of the bout marker and/or tramlining does not occur! - Is the Control Station set to auto advancing?

- Has the bout marker function selector been set to thealternating position? The indicator lamp in the push-button should light.

- Has the correct tramlining programme been selected?

- Has the low-lift switch been correctly adjusted? See“3.10 Setting the low-lift height” on page 25. Whenthe low-lift position is reached, a signal is output toengage auto advancing.

- Check whether the low-lift switch mounting bracket isbent, whether it has been caught in an incorrect posi-tion or whether the magnetic sensor is damaged. Is themagnet broken or is it loose? Also check for a possi-ble severed cable or a short-circuit.

82 Ver.1.2 04/03/02

RDA 600-800 C

The drill can be raised although the lift stop is engaged! - Check whether the magnetic valve (C) on the valve

block receives current. See “6.1.3 Hydraulic electricvalves” on page 79.

- Check the low-lift switch as explained above.

If the lift stop valve does not receive current: - See “6.1.1 Electric fault” on page 78.

If the lift stop valve receives cur-rent: - See “6.1.2 Hydraulic fault” on page 78.

The drill cannot be raised and/or lowered! - Check whether the lift stop or low-lift mode has been

set.

- See “6.1.2 Hydraulic fault” on page 78.

If the drill cannot be raised: - Check whether the lift stop or low-lift mode has beenset.

- See “6.1.2 Hydraulic fault” on page 78.

- Check whether the lift stop valve (C) receives currentas a result of a shortcircuit. See “6.1.3 Hydraulic elec-tric valves” on page 79.

- Switch off the Control Station and check whether thedrill can be raised. If it is still not possible to raise themachine, the fault can be found in the hydraulic sys-tem.

- See “6.1.1 Electric fault” on page 78.

The drilling depth of the centre and side sections differs! - Check whether the long piston rod of the folding ram

is completely extended and that the rod does not slow-ly retract during driving.

- Check the weight transfer setting. See “3.6 Weighttransfer setting” on page 21.

- Check the setting of the master and slave systems. See“3.12 Setting the drilling depth” on page 26.

Ver.1.2 04/03/02 83

Troubleshooting

The drill is sinking, i.e. it drills deeper than the set drilling depth! - Is the O-ring on the master ram’s cut-off valve dam-

aged or missing? See “5.10 Replacing the master ramvalve seals” on page 75.

- Does the stop bolt touch the bottom at the rod’s upperend? In this case the spring has been compressed or isdamaged.

The discs do not rotate properly! - Are the seed boxes exposed to undue stress? The seedboxes should sit very lightly.

- Is the soil very soft? It may be necessary to compactthe soil using a roller.

- Is the sowing depth too shallow?

- Have the seed boxes been installed too low? The discsafford better traction if the seed boxes are raised onenotch.

- Are the discs excessively worn?

- Does the soil surface contain a lot of plant scrubs?

- Are the tines of the front implement set too hard re-sulting in soil that is too loose?

The drill does not place seed at the bottom of the furrow! - Are the seed boxes excessively worn?

- Are the seed boxes set one notch too high? The drillwill place the seed more precisely if the boxes are setlow. This does not normally need to be changed fordifferent soil types.

The fertilizer fan does not start!

In order for the fertilizer fan to oper-ate properly, the following should be set: - The hydraulic oil flow to the seed output fan must be

switched on.

- The seed output fan requires a certain amount of hy-draulic oil flow. If the seed output fan has been start-ed, let it run at minimum 2,000 rpm. If the seed outputfan was switched of with the cock, the hydraulic oilflow must be at maximum.

- The PTO must have been switched on.

- The fertilizer fan rpm must have been correctly set.

84 Ver.1.2 04/03/02

RDA 600-800 C

Leakage from the shaft seal on the fan's hydraulic motor! - Leakage from the shaft seal of the hydraulic motor

may be caused by:

- Damage caused during assembly.

- Wear due to dirt.

- Wear due to too high pressure in the drain line.

- A damaged seal caused by very high pressure in thedrain line.The pressure in the drain line can be measured on theconnector block when the plug (on the connectormarked M) is replaced by a manometer adapter. Usea 0-10 bar manometer. The operating pressure shouldnot exceed 2 bars.

- A high pressure may be caused by:

- Excessive oil flow in the drain line.

- Counter-pressure in the hydraulic valve on the tractor.Loosen the drain hose from the tractor and remove thequick connector. Start the fan. Collect the drained oilin a container.Measure the pressure. Measure the amount of oil ex-iting during one full minute.A considerable pressure drop would indicate a prob-lem with the tractor’s hydraulic valve.A small pressure drop would indicate an excessiveflow of oil. Usually the flow in the drain line shouldbe less than 3 l/min.

- Excessive oil flow may be caused by:

- A worn motor.

- A leaking non-return valve on the connector block.Oil from the return line will then leak into the drainline.Clean the connector block on the outside and loosenthe hose connecting the motor and the block at the P3port. Carefully start the fan. If oil exits from the block,the non-return valve is leaking.Try to clean the valve (it is preferable to let the valveremain on the block). The valve is positioned betweenP3 and the return line (between the motor port andP1).

The area meter/speedometer has incorrect indication! - Check the cable, connector and connection of the sen-

sor.

- Has the correct drive wheel circumference been pro-grammed into the Control Station (usually 370 cm)?See “3.22.3 Programming” on page 59.

- The value increases in case of too small an area or toolow a speed.

- The value decreases in case of too large an area or toohigh a speed.
