Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that follows it. In addition to design and configuration of equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard seriousness.
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,
typically for machine components that, for functional purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe practices.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 6, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
Prepare for Emergencies
▲ Be prepared if a fire starts
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.

Wear Protective Equipment
▲ Wear protective clothing and equipment.
▲ Wear clothing and equipment appropriate for the job. Avoid
loose-fitting clothing.
▲ Because prolonged exposure to loud noise can cause hear-
ing impairment or hearing loss, wear suitable hearing protection such as earmuffs or earplugs.
▲ Because operating equipment safely requires your full
attention, avoid wearing entertainment headphones while
operating machinery.
Avoid High Pressure Fluids
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, seek immediate medical assistance
from a physician familiar with this type of injury.

Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Escaping fluid under pressure can have sufficient pressure to penetrate the skin causing serious injury. Use a piece of paper or
cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with
hydraulic systems. If an accident occurs, seek immediate medical attention from a physician familiar with this type of injury.
Refer to Figure 3
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.

To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip. Hoses with
an extended-cylinder symbol feed cylinder base ends.
Hoses with a retracted-cylinder symbol feed cylinder
rod ends.
For hydraulic fan and drive motors, connect the hose
under the retracted cylinder symbol to the pressure side
of the motor. Connect the hose under the extended cylinder symbol to the return side of the motor.
The fan motor further requires hookup of a (third) case
drain line, which returns lubricating/cooling fluid.

Hitching Tractor to Planter
Crushing Hazard:
You may be severely injured or killed by being crushed
between the tractor and planter. Do not stand or place any
part of your body between planter and moving tractor. Stop
tractor engine and set park brake before attaching cables and
hoses.
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
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
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.
3-Point Hitch
Refer to Figure 5
1. Connect your tractor 3-point to the planter 3-point
hitch. If using quick hitch be sure planter locks into
hitch securely.
2. Raise tractor 3-point just enough to relieve pressure
off of the parking stand.
Load Sway Hazard:
Adjust 3-point hitch arms and sway blocks to minimize any
side-to-side sway to assure proper tracking in the field and
safe road travel.
3. Connect hydraulic hoses to tractor remotes. See
“Hydraulic Hose Hookup” on page 13
Hydraulic Tongue Hitch
Refer to Figure 6
1. Connect the hydraulic hoses for the tongue circuit.
This needs to be done before hitching in order to
raise and lower the tongue.
2. Set the tongue height to clear the draw bar, back the
tractor into alignment and pin the draw bar.

Hydraulic Charge and Bleed
Normally the hydraulic system is fully charged and bled
at the factory before shipping. If repairs have been made,
substantial amount
s of oil drained from the system, or the following procedures do not correct a problem, see “Bleeding Hydrau-
lics” on page 55.
Lift Hydraulics
Bleeding should not be required other than to raise fully
and hold lever on for one minute or until all cylinders
extend fully. If this does
Cylinder Hydraulics
Bleeding should not be required other than to fold fully
and hold lever on for one minute or until all cylinders
reach the end of their stroke.
Planter Damage Risk:
Do not fold or unfold without first raising planter completely.
Leveling Frame Side-to-Side
All frame sections must be level to maintain even planting depth. Before using the planter in the field, follow
these steps to make sure the planter is level side-to-side.
Periodic frame-leveling adjustments should not be necessary, but if you are having problems with uneven
depth, check planter levelness and follow these procedures.
Before making any adjustments be sure the lift cylinders
are re-phased and operating properly.
Complete the steps under “Hydraulic Charge and
Bleed” on page 17, before proceeding.
Note: Level frame in planting conditions. Failure to do so
may result in machinery not producing desired results.
Refer to Figure 9
1. Unfold the planter fully and set down. Put in field
position by lowering and pulling forward.

lower than 26in.
4. Check parallel arms behind the pivots to ensure that
parallel arms are parallel with ground or up to 1in
lower in back. If needed, raise or lower the 3-point to
adjust parallel arms.
5. Once parallel arms are parallel with ground or up to
1in lower in back and 3-point is set, measure distance from ground to frame at the pivots.
Refer to Figure 11
6. Measure wings at gauge wheel. If not level with center of frame, adjust eye bolt accordingly.

Refer to Figure 12
2. Check for proper alignment by running a string line
across back of planter toward outer ends of wings.
For proper alignment, outside ends of wings (dimen-
sion A) should be 0-to(dimension B).

3. To adjust wing alignment, shorten or lengthen eye
bolts to change the length of the wing pull bar. Adjust
eye bolts ➀ in or out until dimension A is 0 to
greater than dimension B.
4. Be sure both wings are adjusted equally or the
planter will tend to pull sideways behind the tractor.
Note: Angle of wings is exaggerated for ease of clarifica-
tion.

Marker Extension
Prior to first marker use during planting, unfold each
marker side in field conditions, and check marker exten-
sion. The distance from the mark to the centerline of
each end row unit is:
185in (470cm).
Check also that the mark left is sufficiently visible for your
soil and residue conditions.
For changes, see “Marker Adjustments” on page 41.

Operating Instructions
This section covers general operating procedures. Experience, machine familiarity and the following information
will lead to efficient operation and good working habits.
Always operate farm machinery with safety in mind.
Pre-Start Checklist
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts,
and wear heavy gloves to check for suspected leaks. If an accident occurs, seek immediate medical attention from a physician familiar with this type of injury.
1. Carefully read “Important Safety Information” on
page 1.
2. Lubricate planter as indicated under “Lubrication”
on page 64.
3. Check all tires for proper inflation. See “Tire Infla-
tion” on page 74.
4. Check all bolts, pins and fasteners. Torque as shown
in “Torque Values Chart” on page 75.
5. Check planter for worn or damaged parts. Repair or
replace parts before going to the field.
6. Check hydraulic hoses, fittings and cylinders for
leaks. Repair or replace before going to the field.
7. Be sure hydraulic hoses are securely held out of the
ball swivel area at hitch. Failure to do so could cause
hoses to pinch requiring hose replacement.

Folding the Planter
Pinch Point and Crushing Hazard:
To prevent serious injury or death:
▲ Fold only if hydraulics are bled free of air and fully charged
with hydraulic oil.
▲ Stay away from frame sections when they are being raised
or lowered.
▲ Keep away and keep others away when folding or unfolding
planter.
Fold planter on level ground with tractor in neutral. If your
planter has markers, be certain they are folded.
Crushing Hazard:
Center section of planter will move backward while folding.
Allow at least 10ft of clearance behind the planter when folding.
1. Switch drive line clutches off.
Refer to Figure 15
2. Set electronic valve selector switch ➀ in tractor to
“FOLD” to activate fold cylinder hydraulics.
3. Activate lift hydraulics. Raise planter until lift hydraulics are fully raised.

Planter Damage Risk:
Be sure planter’s lift hydraulics are fully raised before folding
or machine damage WILL occur.
Refer to Figure 16
4. Fold planter until wings clear transport hooks ➁ by a
few feet.
➂
➃
Planter Damage Risk:
Failure to keep the 3-point lowered while folding WILL result
in opener or seed delivery system damage.
5. Raise 3-point hitch to elevate wing hooks located on
the tongue above the wings.
6. Fold planter fully so wing locks can engage the wing
hooks ➃.
Refer to Figure 17
7. Lower 3-point hitch to engage wing hooks so tongue
is carried on the wing locks. Allow hitch to float with
planter frame while transporting.
