Leveling the Planter
During initial setup and periodically throughout the planting season, check that the planting units are running level.
When planting, the top of the hopper support panel (1)
should be parallel to the ground as shown in
To level the planter, the bottom of the main frame tube
must run between 20 and 22 inches above ground when
lowered into planting position. See
Figure 1-4.
To obtain the correct height, reposition the planter hitch on
the tongue. Proper tongue adjustment improves seed
placement by allowing the row units to operate parallel to
the ground.
The mounting holes in the hitch have been offset so the

hitch can be turned over and bolted on in four positions,
giving eight possible hitching positions. Use the screw jack
to raise the front of the planter tongue. Adjust the planter
hitch to match your tractor drawbar. See
Figure 1-5.
IMPORTANT: When hitching the planter to a different
tractor, check for a difference in drawbar heights. If
the heights are different, re-adjust height accordingly.
Achieving correct planter position can be difficult with
some attachment combinations, especially when planting
in hard to penetrate soils. Avoid using more attachment
down force than is required.

transmission in neutral. Be aware of the clearance re
quired to unfold the planter.
!
DANGER!
Keep clear of overhead power lines when unfolding planter
and/or markers.

5. When wing gauge wheels contact the ground, pull
planter ahead a few feet while continuing to lower.
This will level wings.
6. Remove the cylinder locks by removing the bent pins
and pivoting the locks off the cylinders. Replace the
bent pin to keep the locks off the cylinder.
7. Position arm wing lock pins as shown, see Figure 2-4.
If wings are not level, it may be necessary to pull forward a few feet to lock wing lock pins.
NOTE: If unfolding planter with hoppers fully loaded, you
will need a tractor with at least 1900 psi hydraulic pres
sure.
1. Make sure hydraulic selector valve is in the “Road” position. See Figure 2-1 on page 12.
IMPORTANT: If the planter has set in the folded position for awhile, be sure the wing gauge wheels are
fully retracted before beginning to unfold planter. If
wheels are not retracted hopper damage will occur
when unfolding planter. Retract wheels by lowering
planter on transport locks.
2. Begin to unfold planter.
3. When wings have cleared the outside hopper on the
center section, raise planter. This will lower the wing
gauge wheels.
IMPORTANT: Make sure the wings have cleared the
outside hopper on the center section before raising
the planter. If raised too soon, the gauge wheels will
cause hopper damage.

Transporting
!
CAUTION!
Do no exceed 20 mph maximum transport speed.
Before transporting the planter check the following items.
1. Transport only with a tractor of proper size. See Tr ac-
tor Requirements in “Section 9 Specifications and
Capacities” on page 61.
2. Hitch planter securely to tractor. Always use a locking
style drawbar pin sized to match the holes in the hitch
and drawbar (minimum of 1" diameter heat treated
pin).
3. Attach safety chain securely to the planter hitch and
the tractor with enough slack in the chain to permit
turning.
4. Plug in safety lights with tractor lights using the standard 7-pin terminal.
5. It is recommended that the planter not be transported
with full hoppers.
6. Make sure the planter is properly folded. Refer to Fold-
ing on page 12.
7. Any time you transport planter, be sure transport locks
are in place.
8. Check to see that the tires on the planter have the
proper inflation, see the
flation Chart” on page 63.
9. Remember, the planter is wider than the tractor and
extreme care must be taken to allow for safe clear
ance.
10. Transport slowly over uneven or rough terrain.
!
CAUTION!
Folded planter will have a high center of gravity. Use caution
when traveling on an uneven surface.
11. Comply with all federal, state and local safety laws
when traveling on public roads.

Rephasing the Hydraulic System
!
WARNING!
Escaping fluid under pressure can penetrate the skin causing
serious injury. Avoid the hazard by relieving pressure before
disconnecting hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result.
Refer to Figure 2-8:
The lift system on your Great Plains Pull-Type Planter is a
master/slave system. All cylinders in the system are 2/way
cylinders. Rephasing the system is accomplished each
time the planter is lowered to the planting position. If unlevel lifting occurs, lower the planter to the ground and hold
the remote lever momentarily. This time will allow oil to go
from the tractor to the master, bypass to the master, bypass to the slave, then return to the tractor.
Marker Hydraulics
!
DANGER!
Never allow anyone near the planter when cycling the markers.
Excessive travel speed of the markers can be dangerous and/or
damage the marker assembly.The flow controls should be properly adjusted before the marker assembly is first put into use.
Refer to Figure 2-9:
The marker hydraulic system is equipped with needle
valves to control how fast each marker operates. The needle valves are built into the sequence valve body. There
are two hex adjustment heads, one for controlling marker
speed up and one for controlling marker speed down. To
adjust the speed of each marker, loosen jam nut, screw
the needle valve clockwise to adjust the marker speed to a
low setting. Fold the marker up and down a few times and
recheck for pinching and kinking of hoses. With the tractor
engine at an operating rpm, adjust the needle valve to limit
the marker to a safe operating speed. Excessive folding
speeds can cause marker damage.

the hydraulic lever and lower the opposite marker. Holding the lever down then will force both markers down.
If the markers are down they can both be raised simultaneously but they can only be lowered one at a time al-
-
ternating from one side to the other.
• When oil is cold, hydraulics operate slowly. Make sure
-
all adjustments are made with warm oil.
• On a tractor where the oil flow cannot be controlled, the
rate of flow of oil from the tractor may be greater than the
rate at which the marker cylinder can accept it. The trac
tor hydraulic control lever will have to be held until the
cylinder reaches the end of its stroke. This occurs most
often on tractors with an open center hydraulic system.
On tractors with a closed center hydraulic system, the
tractor’ s hydraulic flow control can be set so the tractor’s
detent will function properly.

Quick Fill
Attachment
Shut-off valves provided at various locations should be
closed to shut off flow when the planter sets overnight or
for extended periods of time. It is also important to close
the tank valves whenever service on the pump or hoses is
being performed. To prolong the life of the hoses in the
squeeze pump, the discharge manifold must be reposi
tioned to the rearward position when not in use to prevent
hose distortion. See
Figure 2-12.
