1. Escaping fluid under pressure can have sufficient forceto penetrate the skin. Check all hydraulic lines and hosesbefore applying pressure. Fluid escaping from a verysmall hole can be almost invisible. Use paper or card-board, not body parts, to check for suspected leaks. If in-jured, seek medical assistance from a doctor that isfamiliar with this type of injury. Foreign fluids in the tis-sue must be surgically removed within a few hours organgrene will result.

2. Make sure all people, animals, and objects are clear ofthe coulter tool bar before switching the tongue hydrau-lics switch to the "auto" mode.

3. Do not crawl under a raised machine without the trans-port lock blocks securely in place. Sudden hydraulic ac-tivation or failure could cause serious injury or death.

4. Never permit anyone to ride on hitch or planting equip-ment when moving.

5. Never permit anyone to ride tractor when hitch is beingmoved.

6. Do not pull the Center Pivot Hitch faster than 20 milesper hour.

1. Mount the control box at a convenient location in thetractor cab. Connect the 12’ extension cable to the9-pin connector on the back of the control box androute the cable back toward the tractor drawbar areamaking sure it will not get kinked or pinched.

2. Connect the power cord to a good uninterrupted 12volt power source on the tractor. Connecting directlyto the battery is recommended. Plug the cord intothe lead with the 2-Pin connector on the back of thecontrol box. The polarity of the power supply is veryimportant to prevent circuit damage. The white wireof the power cord must be connected to the "+" pos-itive battery terminal and the black wire to the "-"negative battery terminal.

Coulter CommandAssembly AdjustmentsRefer to Figure 7

Coulter command depth sensing wheel assemblieswhich are pre-assembled at the factory are pre-adjustedand should not require further adjustment. If the sensorbox at the depth sensing wheel has been field installed,or if its linkage gets out of adjustment, it must be adjust-ed using one of the following two procedures:

1. The best and most accurate means of adjusting thelinkage inside the sensor box makes use of a volt-meter which reads 0-12 volts DC. The Control Box inthe tractor must be properly connected to a powersource and the POWER switch must be ON. TheTONGUE HYDRAULICS switch should be in theMANUAL mode. The wiring harness must be con-nected to the control box and the sensor box. Thedepth sensing wheel should be off the ground withthe arm rotated down as far as its spring-loadeddown-pressure link will allow. Remove the coverfrom the sensor box and inspect the internal linkagefor proper assembly.

Figure 6Coulter Command Control Box

9/21/05

With the depth sensing wheel in the max down posi-tion, the voltage potential between the lead contain-ing the WHITE WIRE and the ground lead (BLACKWIRE) in the gauge wheel sensor box (#1) shouldbe 5 volts DC plus or minus 1/4 volt. To adjust thegauge wheel sensor box linkage, loosen the 3/8"hex flange nut (#2) on the sensor spindle and rotatethe circular disk (#3) until the voltage potential be-tween the lead containing the WHITE WIRE and theground lead (BLACK WIRE) (#1) is 5 volts DC plusor minus 1/4 volt. Rotating the circular disk counter-clockwise increases voltage potential, and rotatingthe circular disk clockwise decreases the voltagepotential. Once the correct voltage potential isachieved, tighten the 3/8" nut. Be careful not to ro-tate the circular disk as you tighten the nut. Replacethe sensor box cover.

2. The second means of adjusting the linkage insidethe sensor box involves measuring from the insideedge of the box to the left pivot of the formed round-bar link. The depth sensing wheel should be off theground and rotated down as far as its spring-loadeddown-pressure link will allow. Remove the coverfrom the sensor box and inspect the internal linkagefor proper assembly.With the depth sensing wheel in the max down posi-tion, the pivot between the vertical flat-bar link andthe formed round-bar link should be 15/16" from thefront inside edge of the sensor box.With the sensor box linkage properly assembled,loosen the 3/8" hex flange nut on the sensor spindleand rotate the circular disk until the pivot between thevertical flat-bar link and the formed round-bar link is15/16" + or - 1/16" from the front inside edge of thebox. Be careful not to rotate the circular disk as youretighten the nut. Replace the sensor box cover.

3. Some models of the sensor box have a mark on thevertical flat-bar link which should line up with a markon the link’s slotted mount plate at the correct presetvoltage. With the depth sensing wheel in the maxdown position, the marks should line up at a voltageof 5 volts DC + or - 1/4 volt. Aligning the marks is more

Section 2 Operating Instructions



The Coulter Command couples a microprocessor withelectro-hydraulics to provide a state-of-the-art systemfor maintaining coulter depth regardless of the terrain orsoil type. It also provides coulter depth adjustment"From The Tractor Cab". A manual feature allows manu-al control of the front hydraulic tongue cylinder forhitching, unhitching, or making adjustments. To under-stand the Coulter Command system, one must befamiliar with the functions of the hydraulics and the elec-tronic controls.

Load Sensing HydraulicsTo operate Coulter Command, some tractors with load-sensing or constant-flow hydraulics require a bypassvalve, Great Plains part number 810-400C. Contact yourGreat Plains dealer to order the bypass valve.

After installing the bypass valve, set valve as follows:

Refer to Figure 8

1. Close bypass valve for no oil flow by turning knob (1)on valve clockwise.

Figure 8Bypass Valve

2. Adjust flow-control valve for tractor to a maximum of10 gpm. If you do not have a flowmeter, hook a stan-dard 8-inch stroke, 4-inch bore cylinder to the circuit.At 10 gpm, the cylinder will take about 2.6 secondsto extend.

3. Engage tractor hydraulics for Coulter Command.

4. Using a pressure gauge, turn knob on bypass valvecounterclockwise until pressure gauges reads 1800psi. Lock bypass valve at this setting.

Hydraulic Hook-Up & FunctionTractors with closed-center hydraulic systems andvariable displacement hydraulic pumps.

NOTE: Failure to install a bypass valve on load-sens-ing tractors may cause major tractor damage. Consultyour tractor dealer to verify if the bypass valve is need-ed.

(If you are not familiar with your tractor's hydraulics, con-sult your tractor dealer.)

For tractors with closed-center hydraulics or pressure/flow compensated hydraulics which are powered by avariable displacement hydraulic pump, turn the knurledcontrol knob on the left side of the hydraulic valve com-pletely clockwise and lock it in place with the circular lockdisk. Do not apply any torque to the control knob after itbottoms out or valve damage may occur. Be sure thelock disk is snugged to prevent the control knob from vi-brating loose in field operation.

The tongue cylinder hydraulic circuit consists of the hos-es from ports "P" and "T". Once the hydraulic valve is setfor CLOSED CENTER operation, the Coulter Commandtongue cylinder circuit requires live hydraulic power sup-plied to the port labeled "P". This is accomplished bypushing FORWARD on the tractor remote hydraulic le-ver and LOCKING IT OPEN in this position.

• On John Deere tractors equipped with SOUND-GUARD R Body you must use the LEVER LOCK CLIPJohn Deere Part No. R52667 to lock the lever in theforward position. See your tractor dealer for purchaseand installation of this clip.

• On John Deere 7000 Series tractors, rotate valve de-tent selector to MOTOR POSITION to lock the lever inthe forward position.

• On Case-IH Magnum tractors use the circuit designedfor HYDRAULIC MOTOR CONTROL and lock the le-ver forward in the detent position. The detent pressurewill probably have to be turned up to its maximum set-ting. DO NOT tie the hydraulic lever on past the detentposition with a strap. This could shift the spool beyondits designed operating position and cause systemdamage. See your tractor dealer for hydraulic systemdetails.

• On other model tractors use the circuit designed forHYDRAULIC MOTOR CONTROL and lock the leverforward in the detent position. The detent pressure willprobably have to be turned up to its maximum settingor some other mechanical detent holder will have to beused to hold the lever forward. See your tractor dealerfor the proper means of providing constant pressure/flow to the tongue cylinder circuit.

The Coulter Command hydraulic circuit requires a flowrate of 8 to 12 gallons per minute for efficient operation.On high flow rate tractors, the flow control on the tractorremote may have to be turned down so as not to exceed12 gallons per minute. Flow rates higher than 12 gallonsper minute will not damage the valve, but may causepoor Coulter Command performance.

The remote tractor hydraulic lever will have to be lockedin position to supply oil to the "P" port of the hydrauliccontrol valve, regardless of whether you want to controlthe tongue hydraulic cylinder manually or automatically.

9/21/05



The CPH transport hydraulic circuit contains the hosesfrom the ports marked "V1" and "V2". This circuit mustbe connected to one of the remaining circuits for raisingand lowering the transport system. This circuit must re-ceive hydraulic pressure for raising the machine evenwhile the hydraulic tongue circuit is "locked in" for contin-uous use. If the machine will not raise when the hydraulictongue circuit is "locked in," consult your tractor dealer.You may need to run the transport hydraulic circuit on a"priority circuit" and the hydraulic tongue circuit on an al-ternate remote if the tractor hydraulics allows livehydraulic power to other remotes. If the "priority circuit"is the only circuit suitable for HYDRAULIC MOTORCONTROL, then run the transport hydraulic circuit onthe "priority circuit" and run the hydraulic tongue circuiton an alternate remote with the Coulter Command valvein the OPEN CENTER MODE. See "Tractors with opencenter hydraulic systems or fixed displacement hy-draulic pumps" below.

Tractors with open center hydraulic systems orfixed displacement hydraulic pumps.(If you are not familiar with your tractor's hydraulics, con-sult your tractor dealer.)

For tractors with open-center hydraulics or on tractorswith fixed displacement hydraulic pumps turn theknurled control knob on the left side of the hydraulicvalve completely counterclockwise and lock it in placewith the circular lock disk. Be sure the lock disk issnugged to prevent the control knob from vibrating loosein field operation.

The CPH transport hydraulic circuit contains the hosesfrom the ports marked "V1" and "V2". This circuit mustbe connected to tractor's "priority circuit" to supply hy-draulic pressure for raising the machine even while thehydraulic tongue circuit is "locked in" for continuous use.The "No.1" hydraulic circuit on most open-center tractorsis the priority circuit.

The tongue cylinder hydraulic circuit consists of the hos-es from ports "P" and "T". Connect "P" and "T" to a circuit

9/21/05

other than the "priority circuit". Once the hydraulic valveis set for OPEN CENTER operation, the Coulter Com-mand tongue cylinder circuit requires live hydraulicpower supplied to the port labeled "P". This is accom-plished by pushing FORWARD on the tractor remotehydraulic lever and LOCKING IT OPEN in this position.The remote tractor hydraulic lever will have to be lockedin position to supply oil to the "P" port of the hydrauliccontrol valve, regardless of whether you want to controlthe tongue hydraulic cylinder manually or automatically.

The Coulter Command tongue hydraulic circuit requiresa flow rate of 8 to 12 gallons per minute for efficient op-eration. On high flow rate tractors, turn down the flowrate on the tractor remote, if possible, so as not to ex-ceed 12 gallons per minute. Flow rates higher than 12gallons per minute will increase the heat generated bythe Coulter Command circuit when it circulates this highflow of oil.

Refer to Figure 9

When operating the Coulter Command tongue hydrauliccircuit in the OPEN CENTER mode, use poppet stylequick couplers on the hoses connecting to the tractor.These quick couplers allow better flow through sometractor remotes and may produce less heat when circu-lating continuous hydraulic flow through them. ParkerHannifin offers the poppet style Pioneer quick coupler intheir 8010 Series couplers. For tractors with Pioneerquick couplers use Pioneer 8010-4P poppet style malecouplers when operating in the OPEN CENTER mode.

Operation of Electronic Controls1. Connect the power cord to a good uninterrupted 12

volt power source on the tractor. Connecting directlyto the battery is recommended. Plug the cord intothe lead with the 2-Pin connector on the back of thecontrol box. The polarity of the power supply is veryimportant to prevent circuit damage. The white wireof the power cord must be connected to the "+" pos-itive battery terminal and the black wire to the "-"negative battery terminal.

2. With the remote tractor hydraulic lever locked in po-sition to supply oil to the "P" port of the hydrauliccontrol valve, turn the power switch on.

a. For manual tongue hydraulic cylinder operation,simply move UP-DOWN switch. Moving theswitch to the UP position extends the tonguecylinder, and moving the switch to the DOWNposition retracts the tongue cylinder. If UP re-tracts the cylinder, then your remote hydrauliclever is not supplying oil to the "P" port of the hy-draulic control valve, or the wires going to thesolenoids A and B are reversed. By moving theUP-DOWN switch, the AUTO-MANUAL switchautomatically switches to the MANUAL mode. Ifyou are in the AUTO mode and you want tomanually hold the tongue hydraulic cylinder inthe position set by the automatic controls, justswitch the AUTO-MANUAL switch to MANUAL.

b. For automatic coulter depth control, simplyswitch the AUTO-MANUAL switch to AUTO anddial in the desired coulter depth you wish tomaintain with the coulter depth control knob.

! WARNING!Make sure all people, animals, and objects are clear of thecoulter tool bar before switching the tongue hydraulicsswitch to the "auto" mode. Sudden automatic lowering of thecoulter tool bar could cause serious personal injury or death.

Turning the coulter depth switch clockwise makesthe coulters run shallower. Turning the coulter depthswitch counterclockwise makes the coulters rundeeper. If the hitch is not moving or is on a hard sur-face, turning the coulter depth switch may not causethe tongue cylinder to retract to the desired position.The coulters may not penetrate to the desired depthuntil the hitch is moving. The coulter depth settingcan always be changed "on-the-go" if you desire.With the AUTO-MANUAL switch in the AUTO mode,the coulters should maintain a constant depth re-gardless of terrain, soil type or speed. When liftingand turning in the field, the tongue cylinder will re-main in its last automatically set mid stroke position.When the machine is lowered, the coulters will auto-matically return to their preset depth.

Field AdjustmentsLift SwitchThe switch at the transport lift cylinder of the Center Piv-ot Hitch determines the point in the lift cycle at which theautomatic feature of the Coulter Command will be inter-rupted and the depth sensing gauge wheel will be liftedoff the ground for turning around. Since the Center PivotHitch transport tires can be lowered during operation toprovide flotation for the drill in soft soil conditions, coultercommand should not be interrupted and the depth sens-ing gauge wheel should not be lifted until after thetransport tires are lowered to the point where they are nolonger used for system flotation. This is usually the pointin the lift cycle when the drill openers are just being liftedout of the ground.

A 3/8" x 3/8" square ramp attached to a sliding push rodon the right transport lift cylinder activates a plungerswitch which causes the automatic feature of the CoulterCommand to be interrupted and the depth sensinggauge wheel to be lifted off the ground for turning theCenter Pivot Hitch around in the field.




1. To adjust the lift switch timing, assemble the push rodto the cylinder rod clamp using one of the three adjust-ment holes at the bottom of the push rod. When tight-ening up the 5/16" nylock nut on the pivot bolt, DONOT TIGHTEN IT DOWN TIGHT. The bolt and pushrod must be free to move in the slot of the clamp. It isrecommended to assemble the push rod through itslower-most hole. BE CAREFUL NOT TO "BOTTOMOUT" THE LIFT SWITCH PLUNGER when the plung-er roller climbs the surface of the 3/8" square ramp.

2. To adjust the lift switch position, loosen the two #10screws and slide it forward or backward in the slottedswitch mount holes so the plunger moves "in" onlyabout 1/8" when the cam activates it. DO NOT "BOT-TOM OUT" THE LIFT SWITCH PLUNGER.

! WARNING!Shut the tractor off and put all hydraulic valve levers in neutralposition before attempting to work on or crawl under the ma-chine. Do not crawl under a raised machine without the trans-port lock pins securely in place. Sudden hydraulic activation orfailure could cause serious injury or death.

A properly adjusted lift switch allows the automatic coulterdepth feature to be interrupted early in the lift cycle. Thisprovided the fastest lift cycle times when turning around inthe field. Operating the lift switch early in the lift cycle, alsoprovides the maximum amount of time for the depth sens-ing gauge wheel cylinder to completely extend as themachine is lowered back to field position. It is importantthat the depth sensing gauge wheel cylinder always be ful-ly extended when the Center Pivot Hitch is in field positionto allow the depth sensing gauge wheel to float through itsfull range of motion.

Speed SensorThe Coulter Command depth control system automatical-ly compensates for changes in ground speed. A speedsensor and speed sensor plate mounted behind thecoulter depth sensing wheel monitors the ground speedso the Coulter Command can adjust for it. This sensorshould be in close proximity to the speed sensor plate. Ingeneral, it should never need adjustment. If the sensor

9/21/05

does get moved, it should be adjusted against the speedsensor plate until is just touches the plate in the closestpart of the rotation. A bent speed sensor plate should bestraightened or replaced immediately. To adjust the speedsensor, loosen the two #6 screws on the sensor and slideit toward the speed sensor plate. Rotate the depth sensingwheel to the position where the speed sensor plate is clos-est to the sensor mount, and retighten the sensor mountscrews where the sensor just touches the speed sensorplate.

Hydraulic ValveAll adjustable valve cartridges on the hydraulic valveblocks are preset at the manufacturer and should not betampered with. Tampering with a cartridge valve could re-sult in decreased lift cycle times for the Center Pivot Hitch.

The only required adjustment is on the upper hydrauliccontrol valve. This valve contains a rotary knob for settingthe Coulter Command to be used with either OPEN CEN-TERED or CLOSED CENTERED tractor hydraulics.Check the owners manual of your tractor to determinewhat type of hydraulic system you have.

Refer to “Hydraulic Hook-Up & Function” on page 10 ofthis manual for setting the hydraulic control valve for yourstyle of tractor.

Transport Cylinder Depth ChannelsWhen planting in soft soil conditions where sinking of yourdrill gauge wheels may be a problem, a cylinder stop chan-nel package (GP# 148-181A) is available to allow yourtransport tires to run on the ground and assist in the sup-porting the drill and hitch weight. The 148-181A cylinderstop channel package contains two cylinder stop channels(one for each transport cylinder). Since the transport hy-draulics is a master-slave system, it is only necessary touse one cylinder stop channel on the master lift cylinder onthe left side of the Center Pivot Hitch. The other cylinderstop channel will not work on the slave cylinder located onthe right side of the Center Pivot Hitch because the lift con-trol switch for the Coulter Command mounts to thatcylinder. Use only one cylinder stop channel on the masterlift cylinder (left side) on Center Pivot Hitches equippedwith Coulter Command.


Section 3 Troubleshooting



Problem Possible Cause Solution

Coulters move up when thedown switch is operated anddown when the up switch isoperated.

Not supplying oil to the "P" port of thehydraulic valve.

Reverse the remote hydraulic lever in thetractor.

Reverse the hoses at the quick couplers.

Solenoids wired backward or hoses fromport "A" and port "B" reversed at thehydraulic valve.

Unplug solenoids and swap wire leads tothem.

Automatic coulter depth con-trol stops adjusting coulterdepth.

tongue hydraulics switch bumped to"manual" mode.

Flip tongue hydraulics switch back to"auto" mode.

Tractor remote hydraulic lever not lockedfor constant oil supply to valve.

Lock Tractor remote hydraulic lever withrubber tarp strap or other means.

System variables out of adjustment Turn power switch OFF and back on againso the system variables can reset. Thenflip AUTO-MANUAL switch to AUTO.

Turning the coulter depth knobdoes not set coulters deepenough.

If the tongue cylinder runs completelyretracted, the tractor drawbar is to high.

Use a straight drawbar or one whichsweeps down.

In extremely hard conditions with themachine standing the tongue cylinderpulses but does not retract.

This is perfectly normal.The cylinder willnot penetrate the coulters on a stationarymachine in hard conditions.Pull forwardand check coulter depth on a movingmachine.

If the coulter depth knob is turned to "A"and the tongue cylinder will not com-pletely retract when moving through thefield then the internal sensor box linkage isnot set correctly.

Adjust the sensor box internal linkage. See"Coulter Command Assembly Adjust-ments" on page 9.

If the sensor box linkage is properlyadjusted and tongue cylinder constantlypulses while moving through the field butthe front tongue cylinder will not retract,you do not have enough system weight.

Add weights to the pull hitch frame weightbrackets. Add tool bar weight brackets tocoulter tool bars.

The hydraulic valve constantlypulses when you are stoppedto refill or adjust something.

Hard soil conditions are hindering coulterpenetration while stopped.

Flip tongue hydraulics switch to "manual"mode while you are stopped or turn coultercommand power "off". Pulsing does nothurt the valve, but can be annoying.

Turning the coulter depth knobto "E" does not allow thecoulters to run shallowenough.

The internal sensor box linkage is not setcorrectly.

Adjust the sensor box internal linkage. See"Coulter Command Assembly Adjust-ments" on page 9.

Depth sensing gauge wheelnot lifting off the ground whenCenter Pivot Hitch is raised.

Coulter Command power is OFF or 12 voltpower has been interrupted.

Coulter Command must be connected andthe power must be ON for the depth sens-ing gauge wheel to raise when the AllSeeds Hitch is raised. The depth sensinggauge wheel should raise with the trans-port lift circuit with Coulter Command ineither the AUTO or MANUAL mode is longas the power is ON.

The lift switch has become disconnected orthe lift switch cam on the right transport liftcylinder has been damaged.

Inspect and adjust the lift switch and pushrod cam. See "Lift Switch" under Section2 "Operating Instructions" on page 12.Check cable connections on lift switchlead.
