Hydraulic Hose Hookup:
Great Plains hydraulic hoses have colored coded han-
dle grips to help hook up hoses to the tractor remotes.
Hoses with the same color use the same remote.
Front to Rear Leveling (Turnbuckle Option):
1) Completely unfold the machine while observing the
unit for any hydraulic leaks or loose fittings.
2) Once unfolded, raise the unit to re-phase the lift cir-
cuit. Hold the lift circuit open for 30 seconds to ensure
all air is purged from the hydraulic system.
3) Lower the machine so the front coulter gangs are 1-
2” off of a level surface.
4) Loosen the jam nut (1) and adjust the turnbuckle (2)
(shorten the turnbuckle to lower the front or extended
the turnbuckle to raise the front) until the front coulter
gangs are the same distance off the ground as the
rear coulter gangs.
5) Once level, re-tighten the jam nut (1).

4) Using the (yellow) hydraulic hoses, adjust the
hydraulic cylinder so that the front coulter gangs are
the same distance off the ground as the rear coulter
gangs.

Level Bar Spring Adjustment:
1) To adjust the level bar spring assembly to the fac-
tory setting of 26 5/8”, loosen the jam nut (3).
2) Adjust the nut (4) until the 26 5/8” dimension is
reached between the backside of the spring guide
and front side of the level bar spring rod plate.
3) Once 26 5/8” is achieved, re-tighten the jam nut (3).

Wing Adjustment Turnbuckle:
Note: Prior to leveling the wings, ensure that the
machine is level front to rear.
1) Lower the machine until the coulter gangs are 1-2”
off of the ground.
2) Loosen the jam nuts (5), and adjust the wing turn-
buckles (6) (shortening the turnbuckles raise the
wings and extending the turnbuckles lowers the
wings) to match the center frame.
3) Once the machine is leveled side to side, any fur-
ther adjustment in the field should be down with the
hydraulic down pressure.

Gang Angle Adjustment:
Several conditions will dictate the gang angle setting
that will accomplish the desired result:
Example Of Suggested Settings:
1) Fall Operation: Cover residue and aggressively fill
in tracks.
Setting:
4-6 Degree Gang Angle
4-5” Working Depth
6-8 mph
2) Final Pass: Creating a level surface/planter-ready
seedbed.
Setting:
0 Degree Gang Angle
2” Working Depth
7-10 mph

Wing Fold Assist Proximity Sensors Adjustment
(If Installed):
Note: Wings must be folded up and the wing safety
lock pins installed when adjusting the proximity sen-
sors to prevent damage to the sensor and bracket.
1) Loosen the nuts (7) (one on the front and one on
the back side of the sensor bracket, adjust the proxim-
ity sensor to 1/8” to 1/4” from the front of the proximity
sensor to the rear of the wing tube).
2) Once adjusted, re-tighten the nuts (7) to secure the
proximity sensor in position.

Hydraulic Down Pressure Adjustment: (1200TM,
1500TM, 1800TM, 2400TM, 3000TM)
Note: This setup procedure is for tractors with closed
center pressure compensated or pressure and flow
compensating hydraulic systems. Open center
hydraulics are NOT SUPPORTED.
1) With the machine unfolded, engage the fold/unfold
hydraulics for continuous flow (unfold position).
2) From the tractor cab, adjust the hydraulic flow so
the needle on the bypass gauge is in the green zone
1000-1500 psi (8). Note: The faster the flow of oil
through the system the greater the potential for oil
heating, premature wear or tractor damage.
3) At the valve, adjust the valve (9) to set the initial
down pressure. This is usually set at 300-400 psi (do
not exceed 800 psi).
During field operation, if the wings are running too
high, increase the pressure setting to help level the
machine. If the center of the machine is running too
high, decrease the pressure setting.

Hydraulic Down Pressure Adjustment: (3500TM)
Note: This setup procedure is for tractors with closed
center pressure compensated or pressure and flow
compensating hydraulic systems. Open center
hydraulics are NOT SUPPORTED.
1) With the machine unfolded, engage the fold/unfold
hydraulics for continuous flow (unfold position).
2) From the tractor cab, adjust the hydraulic flow so
the needle on the bypass gauge is in the green zone
1000-1500 psi (10). Note: The faster the flow of oil
through the system the greater the potential for oil
heating, premature wear or tractor damage.
3) At the valve, adjust the valve (11) to set the initial
down pressure. This is usually set at 300-400 psi (do
not exceed 800 psi).
During field operation, if the wings are running too
high, increase the pressure setting to help level the
machine. If the center of the machine is running too
high, decrease the pressure setting.

Hydraulic Down Pressure Adjustment: (4000TM,
4800TM)
Note: This setup procedure is for tractors with closed
center pressure compensated or pressure and flow
compensating hydraulic systems. Open center
hydraulics are NOT SUPPORTED.
1) Close the rear valve (12) by turning it clockwise
until it is completely closed. Then open the valve one
complete turn.
2) Set the tractor flow rate for the hydraulic fold/unfold
system to SLOW.
3) Engage the unfold hydraulic system (continuous
flow).
4) Adjust the front valves (13)(14) to obtain 1200 psi
each.
5) Adjust the rear valve (12) to 1100 psi. Once
achieved, lock the valve using the locking disc.
6) Adjust the front valves (13)(14) to the desired down
pressure. It is recommended to adjust valve (13)
between 300-800 psi for the inner wings and adjust
valve (14) between 200-500 psi for the outer wings.
During field operation, if the wings are running too
high, increase the pressure setting on valves (13)(14)
to help level the machine. If the center of the machine
is running too high, decrease the pressure setting on
valves (13)(14).

Hydraulic Single Point Depth Stop Adjustment:
The hydraulic dept stop will ensure a consistent depth
every time the implement is lowered.
1) Prior to setting the single point depth stop, ensure
that the machine is completely level front to back and
side to side.
2) Lower the implement to the desired working depth
and pull forward. Once satisfied with the working
depth, adjust the depth stop handle to make contact
with the depth stop valve. Note: If a change of depth is
desired, 1 full turn of the depth stop handle either in or
out will change the depth of the machine approxi-
mately 1/4” up or down.

Gauge Wheel Adjustment:
Note: The gauge wheels should be set in the field
position to be 1/2” to 1 1/2” off the ground.
1) Loosen the set screws (16) on each gauge wheel.
2) Turn the jack handle (17) to adjust the spindle
receiver. Adjusting the jack handle counterclockwise
will run the wheel closer to the ground while turning
the jack handle clockwise will cause the wheel to run
further away from the ground.
3) After adjusting the gauge wheel to the desired posi-
tion, re-tighten the set screws (16).

Rolling Reel Spring Adjustment:
The reel down pressure may be adjusted by removing
the pin (18) and then either pushing the handle (19)
forward to increase the spring pressure or by pulling
the handle backwards to decrease the spring pres-
sure. When the desired amount of spring pressure is
achieved, re-insert the pin. Note: It is recommended
to run little or no down pressure in wet conditions.
49372
Hydraulic Rolling Reel Adjustment: (Option)
Reel down pressure can be adjusted on the move
depending on the desired results.
Using the gauge on the back of the machine:
0 = No pressure/transport position/wet conditions
1-5 = Ideal operating range
6 = Most pressure/extremely hard soil
Note: Running the rolling reel at 6 can raise the rear of
the machine out of the ground and can cause the
machine to be unlevel.
