CHAPTER 4

SAFETYThe above Safety Alert Symbol means ATTENTION!BECOME ALERT! YOUR SAFETY IS IN-VOLVED! It stresses an attitude of ‘‘Heads Up forSafety’’ and can be found throughout this Operator’sManual and on the machine itself.

BEFORE YOU ATTEMPT TO OPERATE THISEQUIPMENT, READ AND STUDY THE FOL-LOWING SAFETY INFORMATION. IN ADDI-TION, MAKE SURE THAT EVERY INDIVIDUALWHO OPERATES OR WORKS WITH THISEQUIPMENT, WHETHER FAMILY MEMBEROR EMPLOYEE, IS FAMILIAR WITH THESESAFETY PRECAUTIONS.

Our Company ALWAYS takes the operator and his/hersafety into consideration when designing its machineryand guards exposed moving parts for his/her protection.However, some areas can NOT be guarded or shieldedin order to assure proper operation. In addition, thisOperator’s Manual and Decals, on the machine, warn offurther danger and should be read and observed closely.

DANGER‘‘DANGER’’ indicates an imminently hazard-ous situation which, if not avoided, will resultin death or serious injury.

WARNING‘‘WARNING’’ indicates a potentially hazard-ous situation which, if not avoided, couldresult in death or serious injury.

CAUTION‘‘CAUTION’’ indicates a potentially hazardoussituation which, if not avoided, may result inminor or moderate injury. May also alertagainst unsafe practices.

1. Disengage the tractor PTO.

2. Shut off the tractor engine, remove the starterswitch key and take it with you.

3. Wait for all movement to stop.

4. Remove the Telescoping PTO Drive and ALLpower connections from the tractor.

ONLY when you have taken these precautions canyou be sure it is safe to proceed. Failure to followthe above procedure could lead to death or seriousbodily injury.

MANDATORY SAFETY SHUTDOWNPROCEDURE

BEFORE unclogging, cleaning, adjusting,lubricating or servicing the unit:

ADDITIONAL SAFETY REMINDERSSome photographs, used in this manual, may showDoors, Guards and Shields open or removed forillustration purposes ONLY. BE SURE that all Doors,Guards and Shields are in their proper operatingpositions BEFORE starting the tractor engine to operatethe unit.

Normal Mixer operation does NOT require access to thetop of the Mixer Tank. However, if special feeds (liquidprotein, molasses . . . etc) are being added through theTank Lid or the Lid pops open to relieve excess pressure,a ladder (NOT supplied) MUST be used to safely reachthe top of the Tank.

Metal-shielded Drive Tubes MUST NOT be anchoredor tied down.

ALWAYS wear safety glasses with side shields whenstriking metal against metal. It is further recommendedthat a softer (non-chipable) material be used to cushionthe blow. Failure to heed could lead to serious injury tothe eye(s) or other parts of the body.

ALWAYS follow state and local regulations regardinguse of a safety chain and auxiliary lighting when towingfarm equipment on public highways. BE SURE to checkwith local law enforcement agencies for your ownparticular regulations.


SAFETY(Continued)

Only a safety chain (NOT an elastic or nylon/plastic towstrap) should be used to retain the connection betweenthe towing and towed machine(s), in the event ofseparation of the primary attaching system.

Block the Mixer so it will NOT roll after it isdisconnected from the tractor.

Good safety practice dictates that you NEVER tow animplement (without brakes), unless towing vehicleweighs at least one-and-one half (1-1/2) times theweight of the towed implement and its load. For anypublic highway travel and to be in compliance with thisrule, BE SURE that your tractor is heavy enough tocounterbalance the weight of the loaded Mixer.

CAREFULLY inspect ALL Hydraulic Hoses and con-nections, on a routine basis. NEVER use your bare hand;escaping fluid under pressure can cause serious injury.If injured by escaping fluid, see a doctor at once. Seriousinfection or reaction can develop if proper medicaltreatment is NOT administered IMMEDIATELY.

Our Company does NOT sell replacement tires. Inaddition, tire mounting, service or inflation can be

dangerous. Whenever possible, trained personnelshould be called to service and/or mount tires, followingthe tire manufacturer’s instruction. If you do NOT havesuch instructions, contact your tire dealer or ourCompany.

CHAPTER 6OPERATION

EMERGENCY SHUTDOWNIn an emergency or in case a foreign object enters theMill Inlet, STOP Mixer operation IMMEDIATELY bydisengaging the tractor PTO.

GENERAL INFORMATION

WARNINGBEFORE starting the tractor engine andrunning the Mixer, review and comply withALL SAFETY recommendations set forth inthe SAFETY chapter of this manual.

NOTE: Before starting to grind material, BESURE the Tank Lid and Discharge Slide are closedand the Collector Cover is open.Best performance, smooth operation, uniformity ofmixing and extended component life are obtained byoperating the Mixer on level ground. To prolong the lifeof the Drive Line components, always maintain astraight-line alignment between the tractor and Mixer.

The most efficient grinding will be obtained bymaintaining the tractor rated PTO speed which producesa Mill Cylinder speed of 2700 RPM. Cylinder speedshould NOT be allowed to exceed 3000 RPM or dropbelow 2400 RPM. Before starting to grind, BE SUREthe Discharge Slide is completely closed.

For best mixing action inside the Tank, add supplementsafter a small amount of feed has been ground. Then add drygranular materials next and hay or straw last. Grind heavyfeeds before light feeds since light feeds do NOT mix asreadily if ground first. When heavy feeds are high inmoisture content, the heavy damp material should be mixedinto the light material to obtain a better mixing action.

NOTE: DO NOT attempt to grind feeds with toohigh a moisture content. This can cause a packingproblem, plugging and result in poor mixing.Abnormally damp materials will NOT feed nor mixwell.

Liquids, such as molasses, should only be added eitherby using an accessory Molasses Attachment or by directapplication through the Mixing Tank Lid (and only afterthe Tank is filled halfway).

Observe the action of the ground feed through theMixer Tank Windows. When the Tank is full, grindingshould be stopped immediately. After all the groundmaterial is cleared out of the Mill, stop the Mixerby exercising the MANDATORY SAFETY SHUT-DOWN PROCEDURE (page 12) and disengagingthe Pin on the Mill/Blower Drive Sheave.

NOTE: DO NOT overfill the Mixing Tank. Thiswill cause the feed to pack and place unnecessarystress on the Drive Line components.

Also, always keep the Tank Lid closed and properlylatched in position so that, if the Tank accidentallybecomes overloaded, the Lid can pop open and releasepressure inside the Tank.

The three full-length Windows on the side of the Tankare calibrated with numbers representing bushels ofground feed. Check all three Windows for an accuratevisual indication of the amount of material in the Tank.

NOTE: For the best achievable accuracy inrationing or proportioning, the Mixer should beequipped with an optional Electronic Scale.

After grinding is completed, stop the tractor anddisengage the Mill/Blower Drive Sheave Pin. Then,start the tractor again and allow the Mixer to continuerunning for several minutes to thoroughly mix theground feed. If the Mixer is to be transported for anydistance, it is advisable to disengage the Mill and allowthe Mixer to run.

NOTE: To prevent damage to the TelescopingDrive and Drive Line components whiletransporting the Mixer with the Tank full and mixing,disengage the tractor PTO before turning corners.


MIXER POWER

Fig. 21

NOTE: When starting to run the Mill and Blower,engage the tractor PTO at a slow idle speed. Then,advance the PTO speed to the appropriate 540 or1000 RPM rated load speed.

Component FunctionMaterial enters the Cylinder Chamber through the MillInlet and is drawn into the Cylinder by a vacuum belowthe Cylinder. The vacuum below the Cylinder isobtained by the physical location of the Blower Inletbelow the Cylinder.

The Cylinder is composed of sixty-six SwingingHammers which are equally divided among three rowsaround the Cylinder. As the Cylinder rotates at therecommended speed of 2700 RPM, the Hammers grindthe material and force it through the Screen. Oncethrough the Screen, the ground material drops down tothe Mill Outlet where the Intake Auger conveys it to theMixing Tank. Lightweight chaff or dust is drawn intothe Blower Inlet and forced by the Blower up into theCollector where it is refined and separated. More denseparticles are directed back down into the Intake Augerand conveyed into the Mixing Tank.

SCREENSThe Mixer Mill is designed specifically for operationonly with a material Screen installed. NumerousScreens are available with various size holes to accom-modate different material and grinding requirements.


The following chart gives hole size recommendationsfor some of these materials and grinding requirements.Two Screens (of the Customer’s choice) are furnishedwith the Mixer.

Refer to the Optional Features and Accessories chapter ofthis manual for a list of all the sizes available. For addedconvenience, a Screen Storage Rack is provided on the leftside of the Mixer between the Tank and the Tire.

To install or change a Screen, proceed as follows:

WARNINGBE SURE to exercise the MANDATORY SAFETYPROCEDURE (page 12), BEFORE proceeding.

1. Unlatch and open the Mill Screen Cover.

2. With the Cover completely open, the ScreenSupport lowers and releases the Screen. Lift theexisting Screen out of the Support.

3. Position and install the new (or different) Screeninto the Support.

4. Close and latch the Mill Screen Cover.

DANGERNEVER operate the Mill unless the Mill ScreenCover is closed and properly latched.

NOTE: When a Screen is correctly installed, itshould fit tight against the Mill Throat Plate and butttightly against the Mill Frame Hood Sheet when theMill Screen Cover is closed and securely latched.

The fineness of grinding is a factor of Mill speed,condition of the Hammers and the size and sharpness ofthe Screen. Considering that Mill speed is maintained at2700 RPM and also that the Hammers are in goodcondition, the efficiency of the Mill will decrease if toofine a Screen hole size is used and/or if the holes arebadly worn. If grinding fineness is deteriorating, theScreen should be removed and rotated to place the sharphole edges against the direction of Cylinder rotation orthe Screen should be replaced.

CAPACITYMX170 Mixing Tank capacity is 135 Bushels (170cubic feet), by volume. The Tank will holdapproximately 3 Tons of ground feed consisting ofaverage weight corn, small grain and/or concentrates.More or less weight (per Tank) is possible, dependingupon whether the material which is being ground islighter or heavier than average. The following chart isa copy of the Decal on the side of the Tank which showsWindow markings in Bushels with correspondingweights for a few common types of material. Grindingcapacity of the Mill can and will vary due to the type ofmaterial being ground, the moisture content of thematerial, and the horsepower of the tractor used tooperate the Mixer.

The Mixer is designed for operation by a 50 to 115 hp 540RPM tractor or by a 50 to 145 hp 1000 RPM tractor.Maximum Mill capacity is obtained by operating at therated PTO speed which maintains consistent CylinderSpeeds.

Above are average weights. Weights depend upon fineness of grinding, moisture content, and the originalweight of the Feed. Metric units are Hectoliters (HL) and Kilograms (KGS).

CONCENTRATE HOPPER (Fig. 22)

NOTE: Certain medicated feed additives anddrugs, which may be mixed by some operators forspecial animal rations (such as EP-250 sulfa for usewith feeder pigs), may leave residual dust/material onthe walls of and in the bottom of portable mixers. Inorder to avoid the serious problems (both to theanimals and your right to do business), which couldoccur if this material is ingested by other animals,each time you use your Mixer for this type of materialand after you have unloaded the material from theTank, completely hose out the Tank before grinding ormixing any feed for other animals.

The Concentrate Hopper is used to place dry additives intothe Mixer. A Magnetic Catch is used to hold the Coveropen. A Bag Guard is provided and should NEVER beremoved while operating the Mixer. A Paper Bag Breakeris also provided. BE SURE to flip the toothed-side overwhen the Bag Breaker is NOT being used.

WARNINGNEVER remove the Bag Guard nor use theConcentrate Hopper without the Guardcovering the Hopper opening.

Small quantity, highly potent additives (medicines,

vitamins, etc.) should be placed into the Tank throughthe Tank Lid opening on top of the Tank, after a smallamount of material has been ground, so as to give themas much time as possible to be thoroughly mixed withthe ground feed. BE SURE to close and latch the TankLid before continuing to grind and mix.

The Bale Feeder Attachment has a Push-to-Stop Bar whichis linked to an Idler to engage/disengage the Bale FeederCylinder. The Feeder Table Apron is Chain-driven by aHydraulic Motor which is connected in parallel with aGovernor to the Motor Speed Control Valve. TheGovernor is Belt-driven off the Bale Cutting CylinderShaft and regulates hydraulic oil flow to the Apron DriveMotor. If the Cutting Cylinder slows down, the TableApron will stop and allow the Cylinder to work back up tonormal speed before advancing more material into theCylinder. The feeding rate of the Table Apron Chain canbe regulated by Slow-Fast Control Handles from eitherside of the Bale Cutting Cylinder.

NOTE: To achieve best performance andextend component life, it is recommended that:

The Slow-Fast Control Handles should be positioned toadjust the Apron speed to bring in feed at a rate whereoptimum tractor PTO speed can be maintained.

By correctly setting the Apron speed, the Governor willbe allowed to slow down or stop the Apron when slugsor damp material enters the Cutting Cylinder.Furthermore, by correctly adjusting Apron speed,overall grinding operation will be smoother and tractoroverload can be prevented. If the Slow-Fast Control isimproperly adjusted too fast for less than ideal cropconditions, the Governor will be kicking in and out moreoften than desired. This condition will result in unevengrinding and unnecessary wear on the internalcomponents of the Governor.

The Small Grain Hopper has a mechanically linkedSliding Plate and Control Handle to regulate the flowinto the Mill Inlet opening.


NOTE: As a safeguard for Mill and Mixercomponents as well as livestock, a Magnet Kit isavailable for installation into the Small GrainHopper. This Magnet will extract harmful metaldebris before it enters the Mill Inlet.

OVERLOAD PROTECTION

NOTE: BE SURE to stop all Grinder Mixeroperations IMMEDIATELY when Shear Bolt failureis detected.

Intake Auger Drive (Fig. 21)

The Intake Auger of the MX170 Mixer is protected bya 1/4 x 1″, Grade 2 Shear Bolt secured with a HexagonNut. Extra Shear Bolts are stored in the lower left sideof the large Front Cover. To order replacement ShearBolts and Nuts, specify 900091 to obtain a package of(8) 1/4 x 1″ Grade 2 Bolts and Nuts.

Transmission Drive (Fig. 31)

The Transmission Drive Shear Flange is furnished witha regular Grade 5, 3/8 x 1-1/4″ Hexagon Head CapScrew which is threaded into the tapped hole of theDrive Sprocket. A 3/8″ Jam Nut is used to lock theposition of the Screw. The tip of the Screw is designedto be sheared off when an overload condition arises.Then, the Jam Nut can be loosened and the Screwthreaded farther into the Sprocket to restore overloadprotection. After about three times, the 3/8 x 1-1/4″

Screw will have to be removed and a new Grade 5 CapScrew installed.

Main Drive (Fig. 21)The 8 “A” Section Drive Belt, which links the Mill/Blower Driven Sheave to the Drive Sheave, providesoverload protection for the Mill and Blowercomponents. If plugging or breakdown occurs in theMill or Blower areas, the Mill/Blower Drive Belt willslip and stop turning the Mill/Blower Drive Shaft.

NOTE: BE SURE to stop all Mixer operationIMMEDIATELY when Drive Belt slipping isdetected.

Hydraulic SystemThe Pressure Relief Valve, on the output side of theHydraulic Pump, provides overload protection for theentire Hydraulic System. The Relief Valve will permitpressure build-up to a factory set value of 2000 PSI. TheMixer Hydraulic System operating pressure range isnormally 200 to 1500 PSI. Thus, if one of the HydraulicMotors is stopped by a malfunction of the component itis driving, the pressure will build up to the factory setcut-off pressure and the Relief Valve will automaticallystop flow throughout the entire Hydraulic System. Afterthe problem is corrected, the Relief Valve willautomatically reset and restore oil flow to the System.

Discharge Conveyor (Fig. 24)A Pop-up Cover is provided on the top end of theDischarge Conveyor. It protects the Discharge Auger incase of a malfunction in the Unloading Conveyor Augerwhich might cause a material build-up in the junctionbetween the two Conveyors. If material at the junctionbacks up, the Pop-up Cover will spring open.

NOTE: Shut the On-Off control off IMMED-IATELY if the Pop-up Cover is forced open.

Tank Lid (Fig. 32)The Lid on top of the Mixing Tank has spring-loadedHinges and Latches which enable it to be forced open byoverflowing material inside the Tank. If the Tankaccidentally becomes filled beyond design capacity, theLid will open, allowing the ground feed to spill out, andprevent damage to the Auger and Drive components.

NOTE: BE SURE to stop all Mixer operationIMMEDIATELY if the Tank Lid is forced open. BESURE the Tank Lid is closed and the Latches andHinges are properly adjusted before starting to grindor mix.

UNPLUGGING

WARNINGWhen any part of the unit becomes plugged, BESURE to exercise the MANDATORY SAFETYSHUTDOWN PROCEDURE (page 12) BEFOREproceeding to remove the plugging material.

NOTE: Whenever plugging is detected, stopMixer operation IMMEDIATELY.

Mill, Mill Drive and Mixing Tank

WARNINGIf plugging occurs, shut the tractor offIMMEDIATELY and disengage the PTO.

Plugging of the Mill and/or Mill Inlet can result fromany one or combination of the following situations:overfeeding, Mill Drive Belt slippage, a sheared bolt on


either or both the Intake Auger Drive or the Transmis-sion Drive shear devices, mechanical failure(s) such asbroken Chain(s), a Transmission breakdown, a shearedKey . . . etc., or abnormal crop conditions.

Overfeeding

If plugging develops from overfeeding, the tractor willchoke down and even stall. To remove the plugging,proceed as follows:

1. Shut the tractor off and disengage the PTO.

2. Shut off the Feeder Attachment.

3. Open the Mill Screen Cover, remove the Screenand allow the material to fall down into the IntakeAuger.

4. Disengage the Mill/Blower Drive Sheave Pin.

5. Restart the tractor and engage the PTO at a slowspeed to convey the material into the Tank.


7. Replace the Mill Screen, close and latch theCover, engage the Mill/Blower Drive Sheave Pinand restart the tractor and PTO.

8. Bring the Mill up to the proper running speed andrestart the Feeder Attachment. If the condition ofthe crop remains the same, BE SURE to reduce thefeeding speed to avoid overfeeding.

Mill Drive Belt Slippage

If plugging develops from slipping of the Mill/BlowerDrive Belt, the Mill and Blower will gradually slowdown without much reduction in tractor PTO speed. Toremove the plugging, follow steps 1 through 6 above.After the plugging has been removed, readjust the DriveBelt tension per details in the Adjustments chapter.Then, replace the Mill Screen, close and latch the Cover,engage the Mill/Blower Drive Sheave Pin, restart thetractor and PTO, bring the Mill Cylinder up to the properoperating speed and resume grinding.

Shear Bolts

Blockage in the Mixer or component failure will causethe tractor to choke down or stall. Proceed as follows:


2. Shut off the Feeder Attachment.

3. Open the Jackshaft Drive Chain Guard and checkif the Transmission Drive Shear Bolt has failed. Ifit has sheared, replace the Bolt.

NOTE: Transmission Drive Shear Bolt failurewill usually cause the Shear Bolt for the IntakeAuger Drive to fail.

4. As necessary, open the large Front Guard androtate the Mill Drive Sheave with the Mill/BlowerDrive Sheave Pin engaged. Observe if the ShearFlange and Sprocket are rotating. If NOT, the endof the Bolt is sheared. The Shear Flange andSprocket Flange MUST be aligned so that the Boltin the Sprocket Flange aligns with the slot in theShear Flange. Loosen the Nut and turn the Boltthree (3) complete turns. Then, tighten the Nut tolock the Bolt position.

5. Close and latch the large Front Guard, restart thetractor and PTO and resume operation.

Mechanical Failure(s)

If a mechanical failure occurs, shut off the tractor anddisengage the PTO. Then, open the necessary Guard toinspect the Drive Chain, Sprocket or Key on the IntakeAuger, Jackshaft or Transmission Drives. Repair orreplace any broken component.

If NO mechanical failure is detected, proceed to removethe Transmission Drive Shear Bolt and attempt to rotatethe Jackshaft clockwise. If the Jackshaft turns freely,internal Transmission component failure is probable. Ifthe Jackshaft will NOT rotate at all clockwise, tryturning it counterclockwise. If it can be turnedclockwise, proceed to unload the material in the MixingTank either through the Cleanout Cover or with theDischarge Conveyor. After the Tank is emptied, inspectthe Mixing Auger and Transmission for cause of theplugging. As required, make the necessary correctiverepair. Last, after the cause of the plugging has beencorrected, replace and resecure all Guards andcomponents before attempting to resume operation.

Crop Condition

Abnormal crop conditions prevent smooth flow of thecrop into the Mill Inlet. If plugging occurs in the MillInlet or the Attachment Hopper, the Mixer will continueto operate with NO apparent sign of Cylinderslow-down or tractor loading.

WARNINGBEFORE attempting to unplug the Mill Inletor Attachment Hopper, BE SURE to exercisethe MANDATORY SAFETY SHUTDOWNPROCEDURE (page 12).


Proceed to determine and correct the plugging beforeresuming grinding.

WARNINGKeep hands out of the area of the AttachmentHopper while it is operating.

NOTE: In general, problems of bridging in theMill Inlet opening, due to feeding very light crops orcrops with a high moisture content, can greatly bereduced when the Mixer is equipped with a FeedRoll Attachment.

After the cause of the plugging is corrected, resumefeeding into the Mill at a slower rate until proper flowis obtained. Since crop condition will most likelyremain the same, the infeed rate will have to be adjustedaccordingly.

Blower Inlet & Outlet (Fig. 31)

Plugging in the Blower Inlet or Outlet will be apparentby the visible absence of dust particles in the air aroundthe top of the Collector, the visible presence of dust inthe Mill Throat area and a greatly reduced air dischargefelt at the top of the Collector. If plugging is detected,proceed as follows:

NOTE: Collector Cover MUST always be openwhile grinding.

1. Exercise the MANDATORY SAFETY SHUT-DOWN PROCEDURE (page 12).

2. Open the Mill Screen Cover and remove the Screen.

3. Inspect the Blower Inlet opening at the front leftside of the Infeed Auger below the Deflector.Remove any build-up by unlatching and openingthe Tunnel Access Cover.

4. After the plugging has been removed, replace theScreen, close and latch the Mill Screen and TunnelAccess Cover and attempt to resume grinding.

5. If there is still NO air coming out the top of theCollector, the plugging is in the discharge side(Blower Outlet). So, proceed to step 6.

6. If NO air is being discharged out the topof the Collector, remove and clean out thePipe connected to the Blower Outlet. BESURE to exercise the MANDATORY SAFETYSHUTDOWN PROCEDURE (page 12) beforeattempting to remove the plugging material.

CollectorIf the Collector or its discharge pipe into the IntakeAuger is plugged, the Auger MUST be removedthrough the Pop-up Cover opening. If plugged, anabnormal amount of heavier dust particles and evenground feed will be discharged from the top of theCollector. Proceed as follows:

1. Climb the Ladder and check the inside of theCollector. If a build-up is noted, remove theDischarge Pipe. Proceed to dislodge the pluggingmaterial.

2. Replace the components after the plugging hasbeen removed and resume operation.

Air Relief TubeIf the Tank Lid opens as a result of excessive pressure(inside the Tank), the Air Relief Tube should be checkedfor plugging. Remove the Tube from the top of the Tank,unplug it and replace it.

Discharge ConveyorThe Discharge Conveyor could possibly becomeplugged by tough and bulky material wedging betweenthe Auger and Trough or by water forming into ice if leftstanding for any length of time. To clear the pluggingmaterial proceed as follows:


2. Shut off the ON-OFF Valve and open the Pop-upCover.

3. Clean out any excess material (if present) andattempt to turn the Auger with a wrench until theAuger moves more freely.

4. If the Auger can be rotated, restore tractoroperation and restart unloading. If the Auger canNOT be rotated, the Auger MUST be removedthrough the Pop-up Cover opening. Proceed tostep 5.


5. Remove the Nuts from the (4) Bolts which securethe Motor Mounting Plate to the DischargeConveyor. Then, move the Plate and Motor back (aninch or two) and loosen the Square Head Set Screwwhich secures the Motor and Auger. Then, pry theAuger away from the motor and pull the Auger out.

6. After the plugging material has been removed,replace the Auger, reinstall the Motor and resumeunloading.

Unloading Conveyor (Fig. 24)The Unloading Conveyor could possibly becomeplugged by tough and bulky material wedging betweenthe Auger and Trough or by water forming into ice if leftstanding for any length of time. Another possible causeis operating the Conveyor at too steep an angle (for thetype of material being unloaded) or because of improperinstallation of the Conveyor Extension if being used. Tounplug the Unloading Conveyor, proceed as follows:


2. Shut off the ON-OFF Valve.

3. Attempt to turn the Auger with a wrench until itmoves freely.

4. If the Auger can be turned, restore tractoroperation and resume unloading. If it can NOT beturned, proceed to step 5 after the tractor is shut offand the PTO is disengaged.

5. Remove the Nuts from the (4) Bolts which securethe Motor Mounting Plate to the UnloadingConveyor. Then, move the Plate and Motor back (aninch or two) and loosen the Square Head Set screwwhich secures the Motor and Auger. Then, pry theAuger away from the Motor and remove the Auger.

6. After the plugging material has been removed,replace the Auger, reinstall the Motor and resumeunloading.

NOTE: If the plugging is due to an improperlyattached Extension, the installation should bechecked and corrected before attempting toresume unloading.

NOTE: In order for the Brake Mechanism tofunction properly, the bottom side of the DischargeSpout Flange MUST be checked and kept clean ofgrease and dirt.

The Brake Shoe is designed with a sloped cutout directlybelow the Brake Pad and above the Cam. When theBrake Shoe is new, the Shoe is secured at a positionwhere the deepest portion of the cutout is above the Camand a minimum clearance is between the vertical face ofthe cutout and the Cam. After this Shoe position hasbeen established, the CB, with the two thick Washers,MUST be completely tightened and the CB, with theone thick Washer, MUST be secured just enough toprevent side to side Shoe movement. Do NOT oversightthe CB with one thick Washer. This will cause bindingand prevent Brake function. With the two CB’s properlysecured, the Brake should be disengaged, with theHandle in the 6 o’clock position and, the Brake shouldfully engage when the Handle is moved toward the 10or 2 o’clock positions. Repositioning the Shoe andresecuring the two CB’s may have to be repeated severaltimes to obtain the correct Brake Mechanism function.After proper adjustment is obtained, BE SURE to checkUnloading Conveyor pivoting with the Brakes unlockedto check for freedom of movement.

NOTE: Over a period of regular use and normaloperation, the Brake Shoe will require repositioning(towards the shallower portion of the cutout) torestore correct Brake Mechanism function andcompensate for normal Brake Pad wear.

CHAPTER 8LUBRICATION

GENERAL INFORMATION

WARNINGNEVER attempt to lubricate this unit when anypart of the machine is in motion. ALWAYS BESURE to exercise the MANDATORY SAFETYSHUTDOWN PROCEDURE (page 12) BEFOREproceeding to lubricate this equipment.

NOTE: Before starting the Mixer, make sure theentire unit is properly lubricated and that theTransmission and Hydraulic Reservoir are filled tothe proper oil levels.

It is well to remember that a sufficient amount of oil andgrease will prevent excessive part wear and earlyfailure.

TRANSMISSION OIL LEVEL

NOTE: On a routine basis after every 200 hoursof operation, check the fluid level in the MixerTransmission by removing the Plug located on theside of the Transmission. It requires 1-1/2 U.S.Pints (0.7 liters) of SAE #140 Gear Lube.

The Transmission should be checked occasionally foroil drips and dust accumulation around the Seals. Oildrips or dust accumulation indicate that the Seals areleaking. If the oil is tan in color and foams excessively,this indicates that it has water present. Unless rust spotsappear inside the Transmission, the fluid does NOTrequire replacement.

NOTE: Do NOT overfill the Transmission; onlyfill to the bottom of the Inspection Plug hole.

OILING

Lubricate all Drive Chains, at the intervals of operationlisted, using a good grade of foaming aerosol lubricant,such as NAPA Chain and Cable Lubricant. This type oflubricant increases the life of the Chain 3 to 4 times overthose lubricated at 8 hour intervals with new or usedmotor oil. The recommended method is to spray the

entire length of Chain on the center of the Rollers. It isbetter to lubricate the Chains when they are warm (afteruse, rather than before).

In addition to the Roller Chains, apply motor oil on allother points listed at the intervals specified.

Lubricate Every 5 hours

3. After tension is completely released, the old Beltcan be taken off and the new Belt can be installed.

4. Adjust new Belt tension following details in theAdjustment chapter.

NOTE: The Mill/Blower Drive Belt willdeteriorate more rapidly if improper tension isapplied. Improper Sheave alignment will result inuneven Belt stretch. Overtensioning the Drive Beltshortens Bearing life.

Engaging Pin (Fig. 65)The Pin, which is used to engage or disengage theMill/Blower Drive Sheave, should be checked on aroutine basis for excessive wear or improper seating.Excessive wear on the Pin or the hole in the Hub, inwhich the Pin engages, could result in the Pinaccidentally disengaging in the middle of the Mill andBlower operation. Either component should be replacedif worn excessively.

NOTE: DO NOT attempt to start the PTO untilthe Pin is positively engaged. Using the PTO toengage the Pin will quickly wear it out.

MILL HAMMER ROTATIONOR REPLACEMENT(Figs. 66, 67, 68 & 69)To maintain maximum grinding efficiency, the MillHammers should be rotated before the leading edge ofthe wear radius measures 1/4″ (6 mm) as shown. TheMill Hammers are designed to be conveniently removedand rotated through (4) positions before they requirereplacement. All of the Hammers should be replacedwhen excess wear is apparent. A replacement set of (66)Hammers is available.

The Mill Cylinder contains (3) rows with (22) Hammersin each row. To remove a row of Hammers, rotate theCylinder to the position where the row of Hammers tobe removed lines up with the Access Hole in the left sideof the Mill Housing. Then, with the Access Hole Coverremoved, pull the Cotter Pin out of the right end of theHammer Rod and proceed to pull the Rod out throughthe Access Hole.

SHEAR DEVICES

NOTE: BE SURE to remove the cause of theShear Bolt failure before attempting to resumeoperation.

Intake Auger Shear Device(Figs. 62 & 65)

The Intake Auger Shear Device is coupled to the AugerDriving Sprocket. It is designed primarily as anoverload protection for the Flighting of the IntakeAuger. Under normal circumstances, the Shear Boltwill fail as a result of a malfunction in the MixingAuger Drive, which would then stop material flowfrom the Mill into the Mixing Tank. If an overloadoccurs, the tip of the Bolt will be sheared off and stopIntake Auger rotation. To correct a Shear Bolt failure,exercise the MANDATORY SAFETY SHUTDOWNPROCEDURE (page 12), and proceed as follows:

1. Open the large Front Guard and rotate the MillDrive Sheave with the Mill/Blower Drive SheavePin engaged. Observe if the Shear Flange and Boltare rotating; if they are NOT, the end of the Boltis sheared.

2. Align the Shear Flange and Sprocket Flange sothat the one hole in the Sprocket Flange alignswith the Shear Flange Bolt.

3. After proper alignment is obtained, loosen theLocking Nut and rotate the Bolt inward 3complete revolutions. After the Bolt is turned in,tighten the Locking Nut.

NOTE: BE SURE to remove the cause of theShear Bolt failure before attempting to resumeoperation. After the Bolt is turned in severaltimes and NO longer is long enough to functionproperly, the Bolt MUST be removed andreplaced. Additional Bolts are stored in thelower left corner of the large Front Guard. Apackage of eight (8) Intake Auger Shear Boltscan also be obtained.

Transmission Drive Shear Device(Fig. 60)The Drive Sprocket for the Transmission Drive Shaft isfurnished with a regular Grade 5, 3/8 x 1-1/4″ Cap Screwwhich is threaded into a tapped hole. A 3/8″ Jam Nut isused to lock the position of the Screw. When an overloadoccurs, the tip of the Cap Screw will be sheared off andstop the Jackshaft which is coupled directly to theTransmission Input Shaft. To correct Shear Bolt failure,exercise the MANDATORY SAFETY SHUTDOWNPROCEDURE (page 12), and proceed as follows:

NOTE: If the Transmission Drive Shear Bolt tipshears off and material continues to be fed intothe Mill, the Intake Auger Drive Shear Bolt willprobably also fail and require replacement per theinformation under a previous topic.

1. Unlatch and open the Guard over the JackshaftDrive Chain.

2. Open the large Front Guard and rotate the MillDrive Sheave, with the Mill/Blower Drive SheavePin engaged, to align the Grade 5 Bolt in theSprocket with the hole in the Flange.

3. After proper alignment is obtained, loosen thelocking Jam Nut and rotate the Bolt inward 3complete revolutions. After the Bolt is turned in,tighten the locking Jam Nut. BE SURE to greasethe Fitting of the Sprocket to prevent themechanism from seizing.

NOTE: BE SURE to remove the cause of theShear Bolt failure before attempting to resumeoperation. Also, grease the fitting on the Sprocketany time a Bolt is sheared. Additional Grade 5, 3/8x 1-1/4″ Bolt and Jam Nuts can be obtained.

drawing (Fig. 73) and mark the distance for properTensioner Spring Cable Clamp anchoring. Then, installthe new Cable and route it in the same manner as the oldCable. After the Cable is properly routed, loosely attachthe Cable Clamp. Using a gloved hand, grasp the Cableand hold tension on it while rotating the Winch crankcounterclockwise to unwind the Cable from the WinchDrum and in turn, to obtain enough slack so that theTensioner Spring can be tightly clamped at the mark onthe Cable. With the Cable slack, slide the Clamp andHook over the mark (at the 28″ point on the Cable) andtightly secure the Clamp over the mark.

NOTE: BE SURE to check and readjust, ifnecessary, the position of the Hook on the Springand the way it is attached to the Cable Clamp sothere is minimum bending on the Cable when theSpring is extended.

Winch (Figs. 72 & 74)

WARNINGBEFORE attempting any service on theWinch, BE SURE the Unloading Conveyor islocked and secured to the Transport Bracket.

NOTE: Whenever any service is performed onthe Winch involving Plate removal, the Cableshould be observed to insure it is wound on theDrum evenly.

The Winch, which raises and lowers the UnloadingConveyor, MUST be maintained in proper operating

condition at all times. A drop of oil should be applied tothe Bronze Bushings on a routine basis every 10 hoursof operation. Condition of the Pawl and Spring shouldbe checked every 100 hours for signs of excessive wearor breakage. The Pawl should always be centered on theStop Wheel for positive engagement.

If the Winch is serviced and components are removed,BE SURE the Pawl is correctly centered over the StopWheel by adding or removing Shims on the 5/8″ PivotBolt.

Fig. 74

The Stop Arm, on the Winch Nut, hits against a StopBolt, on the Winch Side Plate, when the Winch Crankis still being turned, after the Conveyor comes to rest.This prevents the Cable from unraveling from theDrum. Position the Stop Bolt so that the Arm just clearswhile cranking the Conveyor up. Access to the Winchcomponents is gained by removing the Cover on the topof the Winch Housing. To remove the Winchcomponents, the Endplate will have to be removed.


CHAPTER 10PREPARING FOR FIELD OPERATION

TRACTOR CONNECTIONS(Figs. 75 & 76)

NOTE: By design, the Mixer can only beproperly hooked up to a tractor which has PTO andhitch dimensions conforming to ASAE StandardS203. To prolong the life of the Drive Linecomponents, always maintain a straight alignmentbetween the Mixer and the tractor.

Refer to the illustrations provided, for alignment detailsand tractor PTO shaft, tractor drawbar and groundclearance dimensions related to a 540 or 1000 RPMtractor and the respective RPM Mixer Drive Line.

After the Mixer is hooked up to the tractor drawbar, raisethe Telescoping Drive from its Storage Hook on theMixer Frame and lock it onto the tractor PTO shaft.

WARNINGBE SURE the Locking Coupler on the end ofthe Telescoping Drive is properly engagedBEFORE starting the tractor. Also, BE SUREthat the Telescoping Drive Shield turns freelyBEFORE starting the tractor.

SAFETY CHAIN (Fig. 78)

NOTE: Refer to the Safety Chain section in theOptional Features & Accessories chapter forordering information.

As required or when desired, the Mixer can be equippedwith a Safety Chain for travel on public highways. TheSafety Chain should be attached to the tractor and Mixeras shown. When attached in this manner, the safetychain should have the following characteristics:

1. Chain is sufficiently slack to allow turns andmovements of either the tractor or the farmimplement, without placing tension on the chain.

2. Chain is of sufficient strength to hold thedecoupled implement (and its load) and tow it tothe shoulder.

WARNINGALWAYS follow state and local regulationsregarding use of a safety chain and auxiliarylighting when towing farm equipment onpublic highways. ONLY a safety chain (NOT anelastic or nylon/plastic tow strap) should beused to retain the connection between thetowing and towed machines, in the event ofseparation of the primary attaching system.BE SURE to check with local law enforcementagencies for your own particular regulations.Unless otherwise prohibited, use a Slow-moving Vehicle Emblem. NEVER tow a Mixeron a public highway at a speed greater than 20mph (32 kph).
