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.
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.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 5,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
2014-07-29 Table of Contents Index 411-099M
2 3P4025AH Table of Contents Index Great Plains Manufacturing, Inc.
Wear Protective Equipment
▲ Wear clothing and equipment appropriate for the job.
▲ Prolonged exposure to loud noise can cause hearing
impairment or loss. Wear suitable hearing protection such
as earmuffs or earplugs.
▲ Avoid wearing entertainment headphones while operating
machinery. Operating equipment safely requires the full
attention of the operator.
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.
Use Safety Lights and Devices
Slow-moving tractors and towed implements can create
a hazard when driven on public roads. They are difficult
to see, especially at night.
▲ Use flashing warning lights and turn signals whenever
driving on public roads.
Use lights and devices provided with implement.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine during operation.
411-099M Table of Contents Index 2014-07-29
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Transport Machinery Safely
Maximum transport speed for planter is 20 mph (32 kph).
Some rough terrains require a slower speed. Sudden
braking can cause a towed load to swerve and upset.
▲ Do not exceed 20 mph (32 km/h). Never travel at a speed
which does not allow adequate control of steering and
stopping. Reduce speed if towed load is not equipped with
brakes.
▲ Do not exceed 13 mph (21 km/h) in turns. The weight of the
planter can cause under-steer, and the height of the planter
is a tipping hazard.
▲ Comply with state and local laws.
▲ Do not tow an planter unless the towing vehicle is rated for,
and ballasted for, the weight of the planter.
▲ Carry reflectors or flags to mark planter in case of
breakdown on the road.
▲ Do not fold or unfold the planter while the tractor is
moving.
Check for Overhead Lines
The planter requires at least 15 feet (4.5 m) vertical
clearance in transport. Contacting overhead electrical
lines can introduce lethal voltage levels on planter and
tractor frames. A person touching almost any metal part
can complete the circuit to ground, resulting in serious
injury or death. At higher voltages, electrocution can
occur without direct line or body contact.
▲ Avoid overhead lines during folding, unfolding, transport
and parking.
Shutdown and Storage
▲ Lower planter, put tractor in park, turn off engine, and
remove the key.
▲ Secure planter using blocks and supports provided.
▲ Detach and store planter in an area where children
normally do not play.

4 3P4025AH Table of Contents Index Great Plains Manufacturing, Inc.
Practice Safe Maintenance
▲ Understand procedure before doing work. Use proper tools
and equipment. Refer to this manual for additional
information.
▲ Work in a clean, dry area.
▲ Lower the planter, put tractor in park, turn off engine, and
remove key before performing maintenance.
▲ Make sure all system pressure is relieved.
▲ Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on planter.
▲ Inspect all parts. Make sure parts are in good condition and
installed properly.
▲ Remove buildup of grease, oil or debris.
▲ Remove all tools and unused parts from planter before
operation.
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
▲ Be familiar with all planter functions.
▲ Operate machinery from the driver’s seat only.
▲ Do not leave planter unattended with tractor engine
running.
▲ Do not dismount a moving tractor. Dismounting a moving
tractor could cause serious injury or death.
▲ Do not stand between the tractor and planter during
hitching.
▲ Keep hands, feet and clothing away from moving parts.
▲ Watch out for wires, trees, etc., when folding and raising
planter. Make sure all persons are clear of working area.

Hitching Tractor to Planter
Use the 3P4025AH planter only with a compatible
tractor. Planter models are ordered with either a 2-point
or 3-point hitch compatible with ASABE S217 /
ISO 730-1 standards:
Category III W (80 to 225 hp / 60 to 168 kW)
Category IV W (180 to 400 hp / 135 to 300 kW)
Category III N (80 to 225 hp / 60 to 168 kW)
Refer to Figure 3
Models with lift-assist are 2-point, and omit the top link
weldment . Models without lift-assist are full 3-point.

Crushing Hazard:
Do not stand or place any part of your body
between the planter and moving tractor. You
may be severely injured or killed by being
crushed between the tractor and planter. Stop
tractor engine and set parking brake before
making hitch adjustments and connections.
Preset Hitch Spacers and Pin
Back the tractor into the desired alignment with the
planter center-line. Normally, tractor and implement
center-lines are matched. For planting on beds, a 4 inch
offset may be desired.
Move and re-secure the hitch pin spacers to capture
the left lower 2-point arm at the desired lateral alignment.
If a top link weldment is present, and the hitch is
Category III W (not shown), move the smaller
Category III pin from storage into the front lower
holes . The Category IV pin may be left in place.

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 4
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.
Color Coded Hose Handles
Color Hydraulic Function
Black Fan pressure and return
(Case drain has no handle.)
Blue Wing down float or down pressure

Gray Fold Cylinders
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 rod ends.
Connect fold hoses to suitable tractor remote valves.
With optional down-pressure, the circuit must be capable
of continuous flow.
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 three lines, one
of which returns hydraulic fluid from the fan motor case.
Protecting Fan Hydraulic Motor Seals
Low Pressure (Case) Drain Connection
1. Attach case drain hose to low pressure drain
connection.
Note: Case drain hose has the smaller1⁄4inch I.D. hose
and small, flat-face, connector.
2. Connect low pressure motor return hose to low
pressure return connector. It is distinguished by a
large (1.06 inch/2.7 cm diameter) quick coupler.
3. Connect pressure hose to tractor remote.

Implement Locks
Depending on configuration, there are 2 to 4 sets of locks
requiring attention at various phases of operations:
Refer to Figure 12
1. Wing Flex Lock Pin (see page 22)
Required to stabilize pivot during folding and
unfolding. Used during planting to prevent wing flex.
2. Wing Lock Pin (see page 22)
Used to keep the wing tool bar at the same height as
the mainframe tool bar. When this pin is installed at
the coupling, the outer wing is either rigid, or can flex
(depending on the planter “flex” configuration).
3. Lift-Assist Lock Channels (Option, page 23)
These channels, stored on the lift-assist weldments,
are installed on the lift cylinder rods to hold the rear
of the planter at raised.
4. Row Lock-Up Pins (Option, page 65)
For converting twin-row to single-row.
Wing pins store in the parking stands when not in use.

Refer to Figure 14
These lock channels must be used during transport and
raised servicing/adjustments. They are also required for
raised storage. To install:
1. Raise the hitched planter (see page 23). Leave the
tractor hitch and implement lift circuits in Neutral.
2. Remove any snap spacers on the cylinder rods.
Store them on the wire loops .

Raising/Lowering Planter
The planter may be raised or lowered while folded or
unfolded.
Figure 14
Lift-Assist Lock Channel
36099
Machine Damage Risk:
Do not raise or lower while any planter folding operations are
underway or partially complete.
Machine Damage Risk:
Always raise planter for reverse/backing operations.
Raise/Lower 3-Point
With a full 3-point planter (no lift assist), raising and
lowering is accomplished entirely with the tractor hitch.
Raise/Lower 2-Point with Lift Assist
Planter raising relies on the lower 2-point arms of the
tractor 3-point hitch in front, and the Lift Assist cylinders
in back. To raise or lower the planter, move the levers for
both the Lift circuit and the 3-point hitch.
Great Plains recommends this sequence (to prevent
lateral dragging of wing components):
• in Raising, operate the planter Lift circuit first, and
• in Lowering, operate the hitch circuit first.
The lift assist circuit may also include the optional down
pressure system. This system engages and disengages
automatically.

Folding
Fold the planter for movements on public roads and
between fields with narrow clearances. Do not use the
folded configuration for parking or storage.
Tip Over / Crushing Hazard and Equipment Damage Risk:
Never unhitch a folded 3-point planter. A folded 3-point
planter could topple backward or forward, causing serious
injury or death, and certain severe equipment damage. When
unhitched, a 3-point planter is supported at the rear only by
row unit tools and spring tension. Slopes, soft soils, and soils
later softened by rain are particularly dangerous.
Electrocution Hazard:
Avoid overhead lines when folding and transporting. When
folded and lifted, the planter requires clearance of at least
15 feet (4.5 m), which is high enough to contact low-hanging
lines. Touching the planter or tractor completes a circuit to
ground, and can result in serious injury or death. At higher
voltages, shock can occur without direct contact.
Crushing Hazard:
Bystanders could be crushed between the folding planter
wings and the planter center frame, or caught in the folding
mechanism. To avoid serious injury or death, keep all
bystanders well away during planter operation.
Machine Damage Risk:
Machine damage will occur if wing flex and lock pins are not
properly configured for folding. Follow the instructions on the
following pages carefully.
▲ Do not allow anyone to be on or near the planter, or beyond
the ends of the planter during unfolding. Numerous pinch
and crush points exist in the mechanism. The wings are
massive. Coulters and row openers are sharp.
▲ Fold only with markers resting in transport cradles.
▲ 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.
▲ Keep away and keep others away when folding planter.
