transport, maintenance and storage of equipment.
Watchforthe followingsafety notations through-out
your Operators Manual:
!
DANGER!
Indicates an imminently hazardous situation which, if
not avoided, will result in death or serious injury. This
signal word is limited to the most extreme situations.
!
WARNING!
Indicates a potentially hazardoussituation which, if not
avoided, could result in death or serious injury.
1. Escaping fluid under pressure can have sufficient force
to penetrate the skin. Check all hydraulic lines and hoses
before applying pressure. Fluid escaping from a very
small hole can be almost invisible. Use paper or cardboard, not body parts, to check for suspected leaks. If injured, seek medical assistance from a doctor that is
familiar with this type of injury. Foreign fluids in the tissue must be surgically removed within a few hours or
gangrene will result.
2. Make sure all people, animals, and objects are clear of
the coulter tool bar before switching the tongue hydrau-
lics switch to the "auto" mode.
3. Do not crawl under a raised machine without the transport lock blocks securely in place. Sudden hydraulic activation or failure could cause serious injury or death.
4. Never permit anyone to ride on hitch or planting equipment when moving.
5. Never permit anyone to ride tractor when hitch is being
moved.
6. Do not pull the Center Pivot Hitch faster than 20 miles
per hour.
7. Always set the hitch in field position before assembling,
lubrication, making adjustments, or servicing. Periodically check bolts for tightness and lubricate all fittings.
8. Shut off hydraulics valves and shut down tractor before
preforming any maintenance to the hitch or crawling under it.
9. Do not allow anyone to operate the machine who has not
been properly trained in its safe operation.
10. Do not operate equipment while under the influence of
drugs or alcohol.
11. Keep hands, feet, hair, and clothing away from all moving parts.
12. Clear the area of bystanders, especially small children
and animals before moving and operating equipment.
Review the safety instructions annually.

1/2" washer (#24) as shownin . Tighten thefirst
jam nut against the cylinder support (#22) and
run the other two jam nuts on, nearly all the way.
c. With the cylinder properly installed, the support
bolts (#28) should extend through the bracket
(#27)on the outer slide tube when thebaseend
and rod end pins are in place.
d. Screw the outer 1/2" jam nut out until the 1/2"
washer (#24) just touches the bracket on the
outer slide tube. Do not put pressure on the cylinder by tightening the 1/2" jam nut. Once the
washer touches the bracket,lock the outer 1/2"
jam nut in place with the center 1/2" jam nut.
e. Install spring (#25) and 1/2" nylock nut (#26).
Tighten nut to compress spring to a 1 1/4"
length.

Control Box
Refer to Figure6
1. Mountthe control boxata convenientlocation inthe
tractor cab. Connect the 12’ extension cable to the
9-pin connector on the back of the control box and
routethecable backtowardthe tractor drawbararea
making sure it will not get kinked or pinched.
2. Connect the power cord to a good uninterrupted 12
voltpower source on the tractor.Connecting directly
to the battery is recommended. Plug the cord into
the lead with the 2-Pin connector on the back of the
control box. The polarity of the power supply is very
important to prevent circuit damage. The white wire
of the power cord must be connected to the "+" positive battery terminal and the black wire to the "-"
negative battery terminal.
With the depth sensing wheel in the max down position, the voltage potential between the lead containing the WHITE WIRE and the ground lead (BLACK
WIRE) in the gauge wheel sensor box (#1) should
be 5 volts DC plus or minus 1/4 volt. To adjust the
gauge wheel sensor box linkage, loosen the 3/8"
hexflange nut (#2) on the sensor spindle and rotate
the circular disk (#3) until the voltage potential betweentheleadcontainingthe WHITE WIRE and the
ground lead (BLACK WIRE) (#1) is 5 volts DC plus
or minus 1/4 volt. Rotating the circular disk counterclockwise increases voltage potential, and rotating
the circular disk clockwise decreases the voltage
potential. Once the correct voltage potential is
achieved,tighten the 3/8" nut. Be careful not to rotate the circular disk as you tighten the nut. Replace
the sensor box cover.

Assembly Adjustments
Refer to Figure7
Coulter command depth sensing wheel assemblies
whicharepre-assembledat the factory are pre-adjusted
and should not require further adjustment. If the sensor
boxat the depth sensing wheel has been field installed,
or if its linkage gets out of adjustment, it must be adjusted using one of the following two procedures:
1. The best and most accurate means of adjusting the
linkage inside the sensor box makes use of a voltmeterwhich reads 0-12 voltsDC.TheControlBoxin
the tractor must be properly connected to a power
source and the POWER switch must be ON. The
TONGUE HYDRAULICS switch should be in the
MANUAL mode. The wiring harness must be connected to the control box and the sensor box. The
depth sensing wheel should be off the ground with
the arm rotated down as far as its spring-loaded
down-pressure link will allow. Remove the cover
from the sensor box and inspect theinternal linkage
for proper assembly.
12619
Figure 7
Sensor Box Adjustments
2. The second means of adjusting the linkage inside
the sensor box involvesmeasuring from the inside
edge of the boxto the left pivot of the formed roundbar link. The depth sensing wheel should be off the
ground and rotated downas far as its spring-loaded
down-pressure link will allow. Remove the cover
from the sensor box and inspect theinternal linkage
for proper assembly.
With the depth sensing wheel in the max down position, the pivot between the vertical flat-bar link and
the formed round-bar link should be 15/16" from the
front inside edge of the sensor box.
With the sensor box linkage properly assembled,
loosen the 3/8" hex flange nut on the sensor spindle
androtatethecirculardiskuntilthepivotbetween the
vertical flat-bar link and the formed round-bar link is
15/16" + or - 1/16" from the front inside edge of the
box. Be careful not to rotate the circular disk as you
retighten the nut. Replace the sensor box cover.
3. Some models of the sensor box have a mark on the
vertical flat-bar link which should line up with a mark
on the link’sslotted mount plate at the correct preset
voltage. With the depth sensing wheel in the max
down position, the marks should line up at a voltage
of5 voltsDC+ or-1/4volt.Aligningthe marks is more

Section 2 Operating Instructions
Great Plains Mfg., Inc.
The Coulter Command couples a microprocessor with
electro-hydraulics to provide a state-of-the-art system
formaintaining coulter depth regardless of the terrain or
soil type. It also provides coulter depth adjustment
"FromThe Tractor Cab". A manual feature allows manual control of the front hydraulic tongue cylinder for
hitching, unhitching, or making adjustments. To understand the Coulter Command system, one must be
familiarwith the functions of the hydraulics and the electronic controls.
Load Sensing Hydraulics
To operate Coulter Command, some tractors with loadsensing or constant-flow hydraulics require a bypass
valve,GreatPlains partnumber810-400C.Contact your
Great Plains dealer to order the bypass valve.
NOTE: Failure to install a bypass valve on load-sensingtractorsmaycause major tractor damage. Consult
yourtractor dealertoverifyif the bypass valveis needed.
After installing the bypass valve,set valve as follows:
Refer to Figure8
1. Closebypassvalvefor no oilflowbyturning knob (1)
on valveclockwise.
17987
Figure 8
Bypass Valve
2. Adjust flow-control valvefor tractor to a maximum of
10 gpm. If youdo not have a flowmeter, hook a standard8-inch stroke,4-inchbore cylinder tothecircuit.
At 10 gpm, the cylinder will take about 2.6 seconds
to extend.
3. Engage tractor hydraulics for Coulter Command.
4. Using a pressure gauge, turnknob on bypass valve
counterclockwiseuntilpressure gauges reads 1800
psi. Lock bypass valve at this setting.
Hydraulic Hook-Up & Function
Tractors with closed-center hydraulic systems and
variable displacement hydraulic pumps.
(If you are not familiarwith your tractor's hydraulics, consult your tractor dealer.)
For tractors with closed-center hydraulics or pressure/
flow compensated hydraulics which are powered by a
variable displacement hydraulic pump, turn the knurled
control knob on the left side of the hydraulic valve completelyclockwise and lockit in placewiththecircular lock
disk. Do not apply any torque to the control knob after it
bottoms out or valve damage may occur. Be sure the
lock disk is snugged to prevent the control knob from vibrating loose in field operation.
The tongue cylinder hydrauliccircuit consists of the hosesfromports "P" and "T". Once the hydraulicvalveis set
forCLOSED CENTER operation, the Coulter Command
tongue cylinder circuit requires live hydraulic power supplied to the port labeled "P". This is accomplished by
pushing FORWARD on the tractor remote hydraulic lever and LOCKING IT OPEN in this position.

John Deere Part No. R52667 to lock the lever in the
forward position. See your tractor dealer for purchase
and installation of this clip.
• On John Deere 7000 Series tractors, rotate valve de-
tentselector to MOTOR POSITION to lock the lever in
the forward position.
• On Case-IHMagnumtractorsusethecircuitdesigned
for HYDRAULIC MOTOR CONTROL and lock the leverforwardin the detent position. The detent pressure
will probably have to be turned up to its maximum setting.DONOTtie the hydraulic lever on past the detent
positionwith a strap. This could shift the spool beyond
its designed operating position and cause system
damage. See your tractor dealer for hydraulic system
details.
• On other model tractors use the circuit designed for
HYDRAULIC MOTOR CONTROL and lock the lever
forwardinthe detent position. The detent pressure will
probably have to be turned up to its maximum setting
orsome other mechanicaldetentholder willhavetobe
usedto hold the lever forward.See your tractor dealer
for the proper means of providing constant pressure/
flow to the tongue cylinder circuit.
The Coulter Command hydraulic circuit requires a flow
rate of 8 to 12 gallons per minute forefficient operation.
On high flow rate tractors, the flow control on the tractor
remote mayhaveto be turned down soas not to exceed
12gallons per minute. Flow rates higher than 12 gallons
per minute will not damage the valve, but may cause
poor Coulter Command performance.
The remote tractor hydraulic leverwill have to be locked
in position to supply oil to the "P" port of the hydraulic
control valve, regardless of whether you want to control
the tongue hydraulic cylinder manually or automatically.

Section 2 Operating Instructions
The CPH transport hydraulic circuit contains the hoses
from the ports marked "V1" and "V2". This circuit must
be connected to one of the remaining circuits for raising
and lowering the transport system. This circuit must receive hydraulic pressure for raising the machine even
while the hydraulictongue circuit is "locked in" for continuoususe. Ifthemachine will notraisewhen the hydraulic
tongue 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 alternate remote if the tractor hydraulics allows live
hydraulic power to other remotes. If the "priority circuit"
is the only circuit suitable for HYDRAULIC MOTOR
CONTROL, then run the transport hydraulic circuit on
the "priority circuit" and run the hydraulic tongue circuit
onan alternate remote with theCoulter Command valve
inthe OPENCENTERMODE.See "Tractors with open
center hydraulic systems or fixed displacement hydraulic pumps" below.
Tractors with open center hydraulic systems or
fixed displacement hydraulic pumps.
(If you are not familiarwith your tractor's hydraulics, consult your tractor dealer.)
For tractors with open-center hydraulics or on tractors
with fixed displacement hydraulic pumps turn the
knurled control knob on the left side of the hydraulic
valve completely counterclockwise and lock it in place
with the circular lock disk. Be sure the lock disk is
snuggedto preventthecontrolknobfromvibrating loose
in field operation.
The CPH transport hydraulic circuit contains the hoses
from the ports marked "V1" and "V2". This circuit must
be connected to tractor's "priority circuit" to supply hydraulic pressure for raising the machine even while the
hydraulictongue circuit is"lockedin" for continuous use.
The"No.1"hydrauliccircuiton mostopen-centertractors
is the priority circuit.
The tongue cylinder hydrauliccircuit consists of the hosesfrom ports"P"and"T".Connect "P" and"T"to a circuit
other than the "prioritycircuit". Once the hydraulic valve
is set for OPEN CENTER operation, the Coulter Command tongue cylinder circuit requires live hydraulic
power supplied to the port labeled "P". This is accomplished by pushing FORWARDon the tractor remote
hydraulic lever and LOCKING IT OPEN in this position.
The remote tractor hydraulic leverwill have to be locked
in position to supply oil to the "P" port of the hydraulic
control valve, regardless of whether you want to control
the tongue hydraulic cylinder manually or automatically.
The Coulter Command tongue hydraulic circuit requires
a flow rate of 8 to 12 gallons per minute for efficient operation. On high flow rate tractors, turn down the flow
rate on the tractor remote, if possible, so as not to exceed 12 gallons per minute. Flow rates higher than 12
gallons per minute will increase the heat generated by
the Coulter Command circuit when it circulates this high
flow of oil.
Refer to Figure9
WhenoperatingtheCoulterCommandtonguehydraulic
circuit in the OPEN CENTER mode, use poppet style
quick couplers on the hoses connecting to the tractor.
These quick couplers allow better flow through some
tractor remotes and may produce less heat when circulating continuous hydraulic flow through them. Parker
Hannifin offersthe poppet style Pioneer quickcoupler in
their 8010 Series couplers. For tractors with Pioneer
quick couplers use Pioneer 8010-4P poppet style male
couplers when operating in the OPEN CENTER mode.

Section 2 Operating Instructions
Great Plains Mfg., Inc.
Operation of Electronic Controls
1. Connect the power cord to a good uninterrupted 12
voltpower source on the tractor.Connecting directly
to the battery is recommended. Plug the cord into
the lead with the 2-Pin connector on the back of the
control box. The polarity of the power supply is very
important to prevent circuit damage. The white wire
of the power cord must be connected to the "+" positive battery terminal and the black wire to the "-"
negative battery terminal.
2. With the remote tractor hydraulic lever locked in position to supply oil to the "P" port of the hydraulic
control valve, turn the power switch on.
a. Formanual tongue hydrauliccylinder operation,
simply moveUP-DOWN switch. Moving the
switch to the UP position extends the tongue
cylinder, and moving the switch to the DOWN
position retracts the tongue cylinder. If UP retracts the cylinder, then your remote hydraulic
leveris not supplying oil to the "P" portof the hydraulic control valve, or the wires going to the
solenoids A and B are reversed. By moving the
UP-DOWN switch, the AUTO-MANUAL switch
automatically switchesto the MANUALmode.If
you are in the AUTO mode and you want to
manually hold the tongue hydraulic cylinder in
the position set by the automatic controls, just
switch the AUTO-MANUAL switch to MANUAL.
b. For automatic coulter depth control, simply
switchthe AUTO-MANUAL switch to AUTO and
dial in the desired coulter depth you wish to
maintainwith the coulter depth controlknob.
!
Make sure all people, animals, and objects are clear of the
coulter tool bar before switching the tongue hydraulics
switch to the "auto" mode. Sudden automatic lowering of the
coulter tool bar could cause serious personal injury or death.
WARNING!
Turning the coulter depth switch clockwise makes
thecoulters run shallower.Turningthe coulter depth
switch counterclockwise makes the coulters run
deeper.If the hitch is not moving or is on a hard surface,turning thecoulterdepthswitchmaynot cause
thetonguecylinder to retract to the desired position.
The coulters may not penetrate to the desireddepth
until the hitch is moving. The coulter depth setting
can alwaysbe changed "on-the-go" if you desire.
With the AUTO-MANUAL switch in the AUTOmode,
the coulters should maintain a constant depth regardless of terrain, soil type or speed. When lifting
and turning in the field, the tongue cylinder will remainin its last automatically setmid strokeposition.
When the machine is lowered, the coulters will automatically return to their preset depth.
Field Adjustments
Lift Switch
The switch at the transportlift cylinder of the Center PivotHitch determines thepoint in the lift cycle atwhich the
automatic feature of the Coulter Command will be interrupted and the depth sensing gauge wheel will be lifted
offthe ground forturning around. Since theCenter Pivot
Hitch transport tires can be lowered duringoperation to
provideflotation forthedrillinsoftsoil conditions, coulter
command should not beinterrupted and the depth sensing gauge wheel should not be lifted until after the
transport tiresareloweredto the point wheretheyare no
longerused forsystem flotation. This is usually thepoint
inthelift cycle when the drill openers are justbeinglifted
out of the ground.
A 3/8" x 3/8" square ramp attached to a sliding push rod
on the right transport lift cylinder activates a plunger
switchwhich causestheautomaticfeatureof theCoulter
Command to be interrupted and the depth sensing
gauge wheel to be lifted off the ground for turning the
Center Pivot Hitch around in the field.

Section 2 Operating Instructions
1. To adjust the lift switchtiming, assemble the push rod
tothe cylinder rod clamp using one of thethreeadjustment holes at the bottom of the push rod. When tightening up the 5/16" nylock nut on the pivot bolt, DO
NOT TIGHTEN IT DOWN TIGHT. The bolt and push
rod must be free to move in the slot of the clamp. It is
recommended to assemble the push rod through its
lower-most hole. BE CAREFUL NOT TO "BOTTOM
OUT" THE LIFT SWITCHPLUNGER when the plunger roller climbs the surface of the 3/8" square ramp.
2. To adjust the lift switch position, loosen the two #10
screws and slide it forward or backward in the slotted
switch mount holes so the plunger moves "in" only
about 1/8" when the cam activates it. DO NOT "BOTTOM OUT" THE LIFT SWITCH PLUNGER.
!
Shut the tractor off and put all hydraulic valve levers in neutral
position before attempting to work on or crawl under the machine. Do not crawl under a raised machine without the transport lock pins securely in place. Sudden hydraulic activation or
failure could cause serious injury or death.
Aproperly adjusted lift switchallows the automatic coulter
depth feature to be interrupted early in the lift cycle. This
providedthefastestlift cycle timeswhenturning around in
thefield. Operatingthe lift switchearly in the lift cycle, also
provides the maximum amount of time for the depth sensing gauge wheel cylinder to completely extend as the
machine is lowered back to field position. It is important
thatthe depth sensing gauge wheel cylinder always be fully extendedwhen the Center Pivot Hitch isin field position
toallowthedepth sensing gauge wheel to float through its
full range of motion.
Speed Sensor
The Coulter Command depth control system automatically compensates for changes in ground speed. A speed
sensor and speed sensor plate mounted behind the
coulter depth sensing wheel monitors the ground speed
so the Coulter Command can adjust for it. This sensor
should be in close proximity to the speed sensor plate. In
general, it should never need adjustment. If the sensor
WARNING!
does get moved, it should be adjusted against the speed
sensor plate until is just touches the plate in the closest
part of the rotation. A bent speed sensor plate should be
straightenedorreplaced immediately. Toadjust the speed
sensor,loosen the two #6 screws on the sensor and slide
ittowardthe speed sensorplate.Rotate the depth sensing
wheelto the position where the speedsensorplate is closest to the sensor mount, and retighten the sensor mount
screws where the sensor just touches the speed sensor
plate.
Hydraulic Valve
All adjustable valve cartridges on the hydraulic valve
blocks are preset at the manufacturer and should not be
tampered with. Tamperingwith a cartridge valve could result in decreased lift cycle times forthe Center Pivot Hitch.
The only required adjustment is on the upper hydraulic
control valve.This valve contains a rotaryknob for setting
the Coulter Command to be used with either OPEN CENTERED or CLOSED CENTERED tractor hydraulics.
Check the owners manual of your tractor to determine
what type of hydraulic system you have.
Referto “Hydraulic Hook-Up & Function” on page 10 of
this manual for setting the hydraulic control valve for your
style of tractor.
Transport Cylinder Depth Channels
Whenplanting in soft soil conditions wheresinking of your
drillgaugewheelsmaybe a problem, a cylinder stop channel package (GP# 148-181A) is available to allow your
transport tires to run on the ground and assist in the supporting the drill and hitch weight. The 148-181A cylinder
stopchannel packagecontainstwo cylinder stopchannels
(one for each transport cylinder). Since the transport hydraulics is a master-slave system, it is only necessary to
useone cylinder stopchannelon the masterliftcylinderon
the left side of the Center Pivot Hitch. The other cylinder
stop channel will not workon the slavecylinder located on
theright side of the Center PivotHitch because the lift control switch for the Coulter Command mounts to that
cylinder.Useonlyonecylinder stop channel onthemaster
lift cylinder (left side) on Center Pivot Hitches equipped
with Coulter Command.

T ransport lift cylinders will not
lift the Center Pivot Hitch for
transport.
OPEN-CENTER tractors with multiple
sets of hydraulic outlets use the #1 circuit for priority flow which slows down
orcutsoffflow to the other circuits. This
problemwill occur if Coulter Command
ports "P" and "T" are plugged into the
#1 circuit.
On CLOSED-CENTER tractors the
Coulter Command should be connected to a circuit capable of HYDRAULIC
MOTOR CONTROL for supplying constantpressure/flowtoremote locations.
If the machine will not raise when the
hydraulic tongue circuit is "locked in,"
consult your tractor dealer. You may
need to run the transport hydraulic circuit on a "priority circuit" and the
hydraulictongue circuit on an alternate
remote if the tractor hydraulics allows
live hydraulic power to other remotes.
Connect transport lift circuit ports "V1" and
"V2" to the #1 hydraulic circuit on OPENCENTER tractors. Ports "P" and "T" of the
Coulter Command hydraulics should connect to another circuit other than the #1 circuit on OPEN-CENTER tractors.
On CLOSED-CENTER tractors, if the
"priority circuit" is the only circuit suitable for HYDRAULIC MOTOR
CONTROL or supplying constant pressure/flow to remote locations, then run
the transport hydraulic circuit on the
"priority circuit" and run the hydraulic
tongue circuit on an alternate remote
with the Coulter Command valvein the
OPENCENTER MODE.See "Tractors
