Safety Information


GENERAL SAFETY (4.1) Dawn Equipment Company strongly recommends adhering to a comprehensive and effective safety protocol when transporting, maintaining, and/or operating any agricultural implement. A 2008 study from the United States Dept. of Labor (http://www.bls.gov/news.release/cfoi.t02.htm) states that farm related fatalities account for almost 10% of the total number of work related fatalities in the U.S.. Additionally, the loss of a limb, or other bodily disfigurement, may permanently affect your ability to carry out the requisite duties necessary to maintain a profitable farming operation. Please take all appropriate precautions to keep you, your family, and your farm safe! DEFINITIONS (4.2) - (Ref: ASAE S441.1) It is essential that you be able to recognize safety signal words and their associated colors. Please be alert to any signs posted on your Dawn Equipment Company products, and/or in your users manual. Make sure you have read all safety messages and that you clearly understand the recommended precautions. If you have questions about any Dawn safety sign, or have further questions about safety recommendations on this or any other Dawn product, please contact us at 800.554.0007. Danger - Indicates an imminently hazardous

situation that, if not avoided, will result in serious injury or death. (RED)

Warning - Indicates a potentially hazardous situation that, if not avoided, will result in serious injury or death. (ORANGE)

Caution - Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury. (YELLOW)

Hazard - A source of potential injury to a person. A complete list of Dawn Equipment Company safety signs with explanations can be found in the appendix of this manual, or any other Dawn Equipment Company users manual. Please review and understand all safety signs.

PROTECTIVE CLOTHING (4.3) Wearing proper attire when working on agricultural equipment is a critical safety precaution. Loose clothing or accessories may become entangled in moving parts causing serious injury or death. Please ensure that loose cuffs, shirts, belts, jewelry, etc. are secured such that they cannot be snagged on, or be drawn into, moving machinery.

Make sure that all necessary protective accessories are readily available, this will increase the likelihood they are used when needed. Stay aware of your surroundings when in the proximity of machinery that is either moving or has the potential for spontaneous movement. PROTECTIVE ACCESSORIES (4.4) It only takes one accident to permanently curtail your performance in the field and on the farm. Equip yourself with all recommended safety accessories, and develop a strategy for ensuring their use when needed.

Safety Information


Safety Glasses / Goggles If you will be using hazardous chemicals, or are striking, cutting or grinding metal make sure you are wearing eye protection.

Earplugs / Sound Mufflers When working around equipment

that generates high amplitude sound (ie , dryers, vacuums),

ear protection is strongly recommended.

Respirator Mask Please carefully read all safety information associated with any chemicals you will be handling. Use a respirator mask when using hazardous chemicals, (ie Insecticides, NH3

Work Gloves If working around machinery with

sharp edges, or rough metal surfaces, work gloves may prevent a few

stiches. Work gloves are inexpensive, and are really worth the investment.

Steel-Toed Boots A good pair of steel-toed boots can save your toes! Avoid an unfortunate accident, and protect your feet.)

First Aid Kit Every shop and tractor

should have a complete first aid kit.

FARM & TRACTOR FIRST AID KIT (5.1) This is a list of provisions for your first aid kit based on NASD and CASA recommendations. General Supplies: • A basic first aid manual • Two triangular bandages with 36” sides (made from bed sheets) • Spray antiseptic (not a pressurized can), or • Sterile saline solution • Twelve adhesive bandages and four safety pins • 2-4 pairs of rubber or latex gloves • Eye goggles • Three small packages of sugar • Mouth protection device for mouth-to-mouth resuscitation • Syrup of Ipecac (use to induce vomiting if advised by the Poison Control Center) • Stainless steel tweezers • Needle • Sunscreen Dressing Supplies: • Six compress bandages, 2”x 2”, 4”x 4”, 6”x 6” • 24”x 72” compress • One roll of adhesive tape • Six pressure bandages • Gauze bandage • Stainless steel bandage scissors (strong enough to cut through denim) • Emergency tourniquet (or elastic wrap/tubing) • Splints: ¼ inch thick x 3 inches wide x 12 to 15 Inches long. • Cold pack • Amputation preservation kit (plastic bags: one large garbage bag, four kitchen-sized and two bread bags) REPORTING AN EMERGENCY (5.2) Ensure that you have access to a radio or mobile phone when operating or repairing farm machinery. Working with a partner whenever possible significantly increases the chances of receiving timely emergency care should one party become severely injured, and/or incapacitated.


Tractor Preparation


TRACTOR TIRES (6.1) In general, set the tractor tires (center to center) at 4x the row spacing (exe. 120” center to center for 30” row spacing). The minimum row spacing for the Pluribus Unit is 22”. Make certain that the tires are inflated to the recommended pressure for your conditions.

The majority of Pluribus Strip-Till users run on 30” centers, and split the previous years rows. This typically places the tractor tires running over stalks. You may want to consider an aftermarket tool designed to flatten the stalks and reduce tire wear. If you are equipped with high precision guidance, you may also consider running at an angle to the previous years rows. The practice of running at an angle can also have additional performance benefits in some conditions.

LIFT CAPACITY (6.2) Due to the low horse power requirements of the Pluribus unit, many users will opt for a smaller tractor to pull the implement. One important factor to consider, however, is the lift capacity of the tractor hitch. Each Pluribus unit can weigh in excess of 700 lbs.. If you will be using a mounted toolbar, please ensure that your tractor is capable of easily lifting the combined weight of the toolbar, the strip-till units and any additional fertilizer distribution equipment. Should your lift capacity be adequate, there is still a potential that you are excessively tail heavy. If you have difficulty steering in the transport position, you may have to add weight to the nose of the tractor.

WARNING!: Driving uphill with a tail heavy tractor is dangerous! Tractors with excessive tail weight are susceptible to rollovers.

(Note: The procedure for determining lift capacity on a tractor equipped with a 3-point hitch can be found in ASAE S349.2)

THREE POINT HITCH (6.3) If you have a mounted tool bar, you will want to ready your 3-Point hitch. Hitches that have seen little use can freeze up. It is recommended that your free up all your links in preparation for toolbar leveling adjustments. Additionally, it is recommended that you install an aftermarket hydraulic upper link so that you can quickly adjust the toolbar pitch as field conditions change.

TRACTOR DRAWBAR (6.4)

The industry standard for tractor drawbars is approximately 17.5” above ground level. Not all manufacturers adhere to this standard, nonetheless it is very important that the toolbar be hitched in such a way that it can be easily leveled fore and aft. If you are unable to connect your toolbar in such a way that it can be easily leveled, please contact Dawn for advice on your particular tractor/toolbar configuration. Make sure the drawbar has eyelets for safety chains. Pulling an agricultural implement without safety chains is dangerous!

TRACTOR HYDRAULIC SYSTEM (6.5) Understanding your tractor hydraulic system is critically important, and you should thoroughly familiarize yourself with the hydraulic system instructions provided by the tractor’s manufacturer. HYDRAULIC PRESSURE (6.5.a) Know the maximum operating pressure of each hydraulic component. Exceeding the recommended pressure can result in equipment damage or failure. Pressure recommendations can be found in the users manual of most agricultural implements. Also ensure that there is adequate pressure, should you have a system that employs multiple hydraulically driven components. HYDRAULIC VALVES / COUPLERS (6.5.b) Hydraulic cylinders are susceptible to abrasion due to impurities in the hydraulic fluid. It is recommended that you use a clean cloth to remove any abrasive particulate that may have collected in and around the valve plug, and the connecting socket. Always keep dust covers in place when valve is not in use. Test your hydraulic hoses and couplers. Make sure there are no leaks.

WARNING!: Hydraulic fluid under pressure is dangerous! Small holes in hydraulic lines may eject streams of fluid at high pressure. Hydraulic fluid that penetrates the skin can cause serious infection that can lead to amputation. Should oil penetrate your skin, even if it is relatively painless, seek immediate medical attention.


Toolbar Preparation


NOTE: With row by row hydraulic downforce, it is likely that extra weight, or weight distributing hydraulic cylinders will be required to keep toolbar wings at proper operational height /angle. Weights should be added near the ends of the toolbar.

TOOLBAR TIRES (7.1) If your toolbar was built for the purpose of carrying striptill equipment, tires on the toolbar should be properly placed without any correction needed. Many users will opt for a used planter, or cultivator toolbar. These toolbars can sometimes work, but gauge wheels must run in front of the toolbar. Toolbars with gauge wheels running between strip-till units will not perform properly. Check that your tires are properly inflated to the recommended pressure for your conditions. HARDWARE INSPECTION (7.2) Ideally, every piece of equipment, every fastener, and every accessory is perfect right out of the box. In the real world, there is a occasional bolt that is not snug, and an occasional fitting just slightly out of spec. It is important to inspect your entire system, to ensure that every bolt is tight and every component is functioning properly. This simple step can significantly reduce downtime due to small imperfections amplifying into equipment failure. HYDRAULIC INSPECTION (7.3) Today’s hydraulic systems make setup relatively safe and easy, but it is still important to check all hydraulic lines and fittings before connecting them to the tractor. It is recommended that all couplers be fitted with dust caps when not in use, and carefully cleaned before connecting. Check for damage on all hydraulic hoses and replace any lines that have been compromised by wear or fatigue. High pressure hydraulic fluid can be dangerous if couplers, lines and fittings are not properly installed and cared for. HYDRAULIC CONNECTIONS (7.4) You should inspect the hydraulic hoses and their connections. Make sure that the fittings, running into actuator, center manifold, and all hoses are secure. Please read and understand the users manual of any hydraulic accessories and connect pneumatic fittings according to the recommendations of the manufacturer.

TOOLBAR MOUNTED EQUIPMENT (7.5) Many toolbars used in conjunction with the Pluribus system carry a number of additional agricultural devices. Fertilizer hoppers, fertilizer distribution systems, pneumatic accumulators and pumps, etc. should be inspected and checked for loose connections whether electrical, hydraulic or mechanical. If you do not have an operators manual for an agricultural device you will be using with the Pluribus Strip-TIll System, it is highly recommended that you obtain and review the equipment manual before using it. TOOLBAR HITCH (7.6) Both drawbar and three-point hitches should be checked for fatigue. Pull-type toolbar hitches should be equipped with safety chains. Safety chains can prevent a serious accident should the toolbar hitch become disconnected from the drawbar. WARNING!: Unsecured agricultural implements can move erratically with extreme force, and may cause serious injury or death.


Tractor / Toolbar Connections


HITCHING (8.1) When you have thoroughly prepared your tractor and toolbar, you are ready to hook-up. There are a wide variety of hitch configurations, and it is recommended that you familiarize yourself with the operation of your hitch. Operational instructions for your hitch type should be found in the users manual of both your tractor and toolbar. 3-POINT HITCH (8.1.a) Most 3-point hitches will be either Category 2 or Category 3 hitches. If you have a category 2 hitch, make sure that your toplink pin is 1” dia. and your lift arm pins are 1 1/8” dia.. If you have a category 3 hitch, make sure that your toplink pin is 1 1/4” dia. and your lift arm pins are 1 7/16” dia.. In some cases you will have to remove, or relocate the tractor drawbar.

If the lift arm is equipped with an extension, release the lock and pull the extension out its full length of travel. Slowly back the tractor up to the toolbar until the lift arms are aligned with the lower hitch pins. Raise or lower the lift arms until the eyelets are concentric with the lower hitch pins. Stop your tractor and engage the parking brake to prevent rolling when pinning the lift arms to the hitch. Pin each lift arm in place and install a spring clip. Restart the tractor and slowly raise the lift arms until the eyelet of the upper link is concentric with upper hitch pin. Once again stop the tractor and engage the parking brake. You may have to lengthen or shorten the upper link to install the hitch pin. After installing the upper hitch pin, make sure to secure it with a spring clip. If you have a “quickhitch” variety 3-point hitch, as before slowly back up to the toolbar until the lower clasps of the quick-hitch rest below the lower hitch pins. Lengthen or shorten the upper link to align the quick hitch with the hitch pins. Raise the quick-hitch until it engages the hitch pins. Make sure the hitch retainers are lowered, and engaged.

DRAWN HITCH (8.1.b) Slowly back up the tractor to the toolbar until the tractor drawbar is near the clevis of the toolbar. Stop your tractor and engage the parking brake. Use the toolbar jack to align the clevis with the tractor drawbar. You may have to reposition the clevis. The lower hitch panel of the clevis should be approximately 14 in. above ground level, so that the upper hitch panel rides abutting the tractor drawbar. Most toolbars have optional settings for the clevis. Once the height of the clevis is aligned with the tractor drawbar, slowly back the tractor until the pin holes of the clevis and drawbar are aligned. If you are using assistance in hitching the toolbar, please make sure no person is between the tractor and the toolbar when in motion. WARNING!: Tractors in motion may behave erratically! Persons caught between a tractor in motion and an agricultural implement could suffer serious injury or death. When you have aligned the pin holes, install the appropriate pin and secure it with a spring clip. Your toolbar should be equipped with safety chains. Make sure to connect the safety chains before moving the toolbar. HYDRAULIC CONNECTIONS (8.2) WARNING!: Shut off tractor and remote cylinder controllers that are in operation before attaching or detaching hydraulic hoses to avoid potential injury from hydraulic fluid escaping under pressure. Ensure that all hoses and fittings are secure before pressurizing system. Refer to installation guides for proper assembly. All agricultural implements equipped with hydraulic components should be accompanied by a users manual that details attaching and detaching. Please carefully follow the instructions provided by the manufacturer. ELECTRICAL CONNECTIONS (8.3) Check to ensure that electrical connections are secure and properly connected. Familiarize yourself with the users manual of any electrical components that your strip-till/fertilizer system might employ. Carefully read the connection procedure found in the users manual of that components manufacturer.

SETTING UP ROW UNIT CONTROLLER (11.1) CONTROLLER DESIGN (11.1a) The row unit controller is capable of being configured to run multiple Dawn products simultaneously, but we will start with the basic downforce configuration.

HARNESS INSTALLATION (11.2)

Reflex Basis Harness

Reflex Strain Gauge Harness

Reflex Strain Gauge Harness will be routed along the parallel linkage on a planter row unit, or behind the actuator on a striptill unit, and then connect to the sensor on depth adjustment assembly. Make sure the excess cable is secure to prevent damage from any pinch points along the linkage.

ROW-TO-ROW CABLES (11.3) Row-to-row cables can be plugged in to either 4 pin receptacle. Ensure they are fully inserted until you hear/feel the locking tap click into place.

REFLEX ACTUATOR VALVES (11.4)

NOTE: Ensure valve cables correspond with the hose routing. Notice – Valves can be purged by pressing the small pin on top.

TERMINATION RESISTORS (11.5) First and last row unit controllers require a termination resistor (PN 90625-180) installed into the second 4-Pin receptacle. PROXIMITY SWITCHES (11.6) Proximity switches deactivate the hydraulic down pressure when the toolbar is raised. They are non-contact switches, so do not compress. They are placed on the lower parallel casting on a JD planter row unit. They should be loosely installed away from the rear until the toolbar is raised and row units are resting on the travel stop. After the Reflex system is powered on, adjust the distance of the prox switch from the casting, starting with it close. Move the switch away from the plate until the internal LED light comes on. Turn back towards the face about 1.5-2 turns of the jam nut and tighten with two 15/16” wrenches. This is easier done by finger tightening the jam nuts, and lowering the bar to create clearance for wrenches.

REFLEX CENTER MANIFOLD ASSEMBLY (12.1)

Select a location to install the center manifold, ideally between the two center rows.

Plumb the pressure and return trunk lines to the indicated ports.

Route your row-to-row hoses from the center manifold directly to the actuators as shown in fig. xxx. Ensure hoses do not get crossed during install. Marking the pressure and return hoses before installation is recommended for ease of identification.

TRUNK HOSES (12.2) Route ½” hose down draft arms allowing enough hose for all folding points. Cut hose to length and crimp supplied fittings to manufacturer specifications.

ROW-TO-ROW HOSE ROUTING (12.3) Starting for the center manifold, route hoses from the corresponding RETURN, PRESSURE & UPLIFT adapters to the row unit actuators. Continue along toolbar to final rows.

Check clearance with seed tubes and vacuum lines to prevent unnecessary wear. It is advisable to have hydraulic hoses routed under any other tubes many times. It may be necessary to alter the angle of the adapters in the actuators to clear obstacles.

The first and final row actuators will require the adapters to be replaced with supplied -8 ORB Hex Hollow Plugs (PN 9533)

NOTE: Pressure and return routing may be interchanged if necessary, but ensure uniformity throughout the system. Valve cables will need to match hose routing.

WING HOSES (12.3) Route wing hoses from outer row units on center section, around the folding point, to the first row unit on wing, ensuring enough slack to fold and unfold without being stretched or pinched. Many times, it is helpful to do this routing with the toolbar half unfolded to visualize the routing.

Planter Hardware Installation


PLANTER HARDWARE INSTALLATION (13.1)

LOWER CLEVIS MOUNT (13.1a)

A lower clevis mount will be included in the Reflex kit. There are three different mounts available, dependent on the planter configuration.

NOTE: Some rows may have FACTORY INSTALLED JD PROX SWITCH ASSEMBLIES in the same location as the Reflex switch. In this case, the tab on the mount plate can be bent in the opposite direction to be installed on the left hand side of the row unit. PRO-SHAFT PLANTERS will receive a threaded stud (PN 103094) to provide clearance for the pro-shaft. It will replace the bolt/bushing on the lower clevis mount near the pro-shaft. Lower cradle will be a weldment to provide clearance for pro-shaft. ( PN 201102). LONG PARALLEL LINK PLANTERS will receive the standard hardware, but will configure it as shown below. It is important to bolt through the two front bushing holes in the lower clevis mount.

UPPER CLEVIS MOUNT (13.1b)

Use original hardware from previous downforce mount to install upper clevis mount as shown.

STRAIN GAUGE (13.1c) Remove the factory installed depth adjust assembly by removing the snap ring, pulling the pin, and dropping the assembly through the bottom of the shank casting behind the openers. Removing one of the gauge wheel arms makes this process simpler.

• Route strain gauge cable along casting to prevent any wear or pinch points.

• Make sure rocker (mustache) is above gauge wheel arms, not stuck below or inside casting.

NOTE: WHEN INSTALLING ACTUATOR, INSERT UPPER CLEVIS PIN FROM THE RIGHT HAND SIDE SO COTTER PIN DOES NOT CONTACT HARNESS CABLES.

TIP: INSTALL PROX SWITCH PLATE AT SAME TIME AS LOWER CLEVIS

MOUNT

Remove Pin to Replace Depth

Adjust assembly

IMPORTANT: Utilize the two front holes

in the casting, NOT the rear open radius!

Use the two lower holes in the switch mount plate to

secure to the casting as shown.


Reflex Operating System


START UP PROCEDURE (14.1) Once all electronic components and hydraulic components are installed, and pressure tested, you will be ready to start the initial setup & test procedure.

Power on the Reflex system using the PCAN switch. You should see the LED lights on the PDM and row unit controllers come on. If there are no lights, check cable connections and batter cable.

Once power is established, open the Dawn Reflex Application on your tablet.

Row unit numbers will show up at the bottom of the window. If toolbar is raised the rows will be shown in a white box. When lowered, the box will turn green, indicating that the down pressure system is active.

At this point, any proximity switched should be adjusted if they are not activating/deactivating rows properly. (fig xxx)

ROWS WILL BE SHOWN IN WHITE WHEN TOOLBAR RAISED

ROWS WILL BE SHOWN IN GREEN WHEN TOOLBAR LOWERED

CALIBRATING STRAIN GAUGE (14.2) Raise toolbar and ensure there is no load on gauge wheel arms.

Tap on any row number to access the ROW UNIT STATUS window. There will be a box in the bottom left that says “Set zero point on all units”. Press this once. (If done while toolbar lowered, or any gauge wheel load on wheels, the process will have to be redone correctly)

SETTING TARGET GAUGE WHEEL LOAD (14.3) Gauge wheel load should be selected by running a small test strip in the specific field and finding the proper downforce to produce the desired soil firmness.

Lower toolbar and establish gauge wheel load. (May need to roll forward to get row units in the ground)

Gauge wheel load will be displayed at the bottom of the top bars for each row.

To update the target load, select desired GWL to the right and push the “Update Setpoint” tab to program.




MANUAL MODE (14.4) By pressing the Manual Mode tab to the left, you will switch from targeting a consistent gauge wheel load, to targeting a selected amount of hydraulic pressure for all units. Rows will turn orange.

By pressing the Gauge Wheel Load tab, you will switch over to displaying the Applied Down Pressure for each row. To update the targeted pressure, select the psi, and touch the orange tab to program.

INDIVIDUAL ROW SETTINGS (14.5) Individual rows may be set up to your specific settings as desired. Whether you want/need to operate rows in manual mode, or have different GWL targets in automatic mode.

Tap on any row number on the Global Status screen to access the individual row’s settings. Any changes made to Gauge Wheel Load (in automatic mode) or Target Down Pressure (in manual mode) will apply to only the individual row controller.

If you want an individual row’s settings to remain unchanged while being able to update settings for all other rows on the Global Status screen, select “Global commands locked out tab”. Press again to undo lockout. Locked out rows will appear in a grey box on the Global Status screen.




TIPS USING UPLIFT ASSIST (14.5a) 1. Observe the Applied Pressure during operation.

• If the average applied pressure in operation is less than 500 psi, increase the uplift pressure. (Large accumulator on the row unit actuator is pre-charged to 500 psi, and causes instability if running at too low applied downforce).

2. Observe the Gauge Wheel Load in operation. • If the actual gauge wheel load is much

higher that the set target, increase the uplift pressure.

3. If an area is known to be wet or soft, increase uplift pressure to counter the weight of the row unit.

WARNING!: Always ensure that system pressure has been relieved before opening any hydraulic component! OVERVIEW OF REFLEX OPERATION (14.5b) KEY TERMS:

1:Automatic Mode – targets the user-set gauge wheel load and applies/relieves pressure to continuously maintain that load. 2. Manual Mode – Bypasses the gauge wheel load and applies/relieves based on manually entered pressure setting. 3. Gauge Wheel Load – Pressure from gauge wheels measured by sensor at base of height adjust assembly.

4. Applied Down Pressure – Pressure being applied to row unit, either by automatically adjusting to target gauge wheel load, or by manually entering a set pressure.

Automatic mode is default setting in normal operating conditions.
