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”onpage6,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
2012-02-23 Table of Contents Index 401-805M
2 YP4425A Table of Contents Index Great Plains Manufacturing, Inc.
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
hearing 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.
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
▲ Read and follow chemical manufacturer’s instructions.
▲ Wear protective clothing.
▲ Handle all chemicals with care.
▲ Avoid inhaling smoke from any type of chemical fire.
▲ Store or dispose of unused chemicals as specified by
chemical manufacturer.
Use A Safety Chain
(Optional hydraulic hitch only. 3-Point has no chain.)
▲ Use a safety chain to help control drawn machinery should
it separate from tractor draw-bar.
▲ Use a chain with a strength rating equal to or greater than
the gross weight of towed machinery.
▲ Attach chain to tractor draw-bar support or other specified
anchor location. Allow only enough slack in chain to permit
turning.
▲ Replace chain if any links or end fittings are broken,
stretched or damaged.
▲ Do not use safety chain for towing.
401-805M Table of Contents Index 2012-02-23

Hitching Tractor to Planter
Crushing Hazard:
Do not stand or place any body part between 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 attaching cables and hoses.
Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing
serious injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
Only trained personnel should work on system hydraulics
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 Hydraulic Function
Green Wing Fold / Marker Fold / Auxiliary
Blue Lift / (and Hitch if hydraulic tongue)
Black Fan
Yellow Hydraulic Drive
Refer to Figure 3
To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip. Hoses with an
extended-cylinder symbol feed a cylinder base end.
Hoses with a retracted-cylinder symbol feeds a cylinder
rod end.
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 line,
which returns hydraulic fluid from the fan motor case.
Machine Damage Risk:
Case Drain Hose must be attached first,
prior to inlet and return hoses being connected.

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 smaller1⁄4in 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 in / 2.7 cm diameter) quick coupler.
Machine Damage Risk:
DO NOT connect the case drain line to a
power-beyond-port.
3. Connect hydraulic hoses to tractor remotes.
Case Drain Hose must be detached last,
to prevent damage to the fan motor.

4. Connect the hydraulic hoses for the tongue circuit.
This needs to be done before hitching in order to
raise and lower the tongue. See “Hydraulic Hose
Hookup” on page 15. Allow slack for hitch
movements. Close the tongue cylinder bypass valve.
5. Make electrical connections for at least the planter
control circuit (necessary to control planter hydraulic
systems). See page 16.
6. Check that hitch local bypass valve is closed.

Equipment Damage Risk:
The hydraulic tongue must be in Float during planter moves.
If it is necessary to move the planter without first
connecting it to a tractor that has a float-capable circuit
for the hydraulic tongue, open the bypass valve on the
1
tongue cylinder. This provides local floating capability at
the tongue.
Raising/Lowering Tongue
In addition to hitching, tongue raising and lowering is
required during fold and unfold to engage and disengage
the wing locks.
With the standard 3-point hitch, the planter tongue is
raised and lowered by raising and lowering the 3-point.
With the optional hydraulic tongue, the planter tongue is
raised by extending the hitch cylinder, and lowered by
retracting the hitch cylinder.

Store Main Parking Stand
Refer to Figure 8 (which depicts the similar YP40 hitch)
1. Raise the tractor hitch slightly to lift parking stands
off ground.
2. Remove the lower pin and the upper pin
holding the parking stand .
3. Move the stand from under the tongue to an inverted
position in the bracket on the left side on the
tongue. Pin in place.
Storing 3-Point Parking Stands
Refer to Figure 9 (shown without tractor for clarity)
1. For the standard 3-point hitch, store the two forward
stands by either of the following methods:
• Remove the top pin , swing the stand out, up and
vertical around the bottom pin , and re-insert the top
pin , or
• Remove the bottom pin , swing the stand inward, to
a horizontal positional under the hitch, and insert the
removed pin at hole under the stand.
Refer to Figure 8
2. Adjust the top link of a 3-point long enough so the
ball swivel does not bottom out when fully raised.
3. Secure hoses so they do not get caught in ball
swivel . Failure to do so could cause hose to be
crushed requiring hose replacement.

Tank Cart Hitching
If using a fertilizer cart, consult the cart manual for:
• hitching cart tongue to planter
• connecting pump control electronics to planter
• connecting fertilizer feed hoses to planter
Complete the tractor-planter hook-up before making any
tank cart connections.
Material Loss Risk:
Open hose and inlet valves when ready to begin planting.
Close them when not in use. Damage to hoses when not
applying material can result in rapid tank depletion.

Heights and Leveling
All frame sections must be at the correct height and level
to maintain even planting depth.
Periodic frame-leveling adjustments should not be
necessary. For problems with uneven depth, check
planter levelness and follow these procedures.
1. Before making any adjustments be sure the lift
cylinders are re-phased and operating properly. If
not, see “Re-Phasing Lift System” on page 27
2. Complete “Bleeding Hydraulics” on page 101.
3. Unfold the planter fully (page 23).
Set Tongue Height
Planter must be unfolded for this procedure.
Refer to Figure 11
Set the initial tongue height, using 3-point or hydraulic
tongue cylinder. Distance is measured at top of tongue to
ground level.
• For standard 3-point hitch:
Set depth stop to capture this working height.
If desired height cannot be attained with normal range
of hitch, swivel coupler weldment may be relocated in
tongue bolt holes.
Note: Tractor 3-point control must be in Depth Control
mode, and not Draft Control mode.
• For hydraulic tongue:
Note the scale reading on the tongue for this height.
[Re]set the tongue height to this value when planting.
Note: Level frame in planting conditions.
Failure to do so may result in implement not
producing desired results.

Checking Planter Height
The planter is designed to operate with all sections of the
main tool bar nominally 26 inches (66 cm) above the
planting surface. The height of the center section is not
routinely adjustable. Set planting depth with row unit
adjustments.
When lowering the planter for the first time on the
planting ground:
1. Completely lower the main tool bar. If necessary, first
lift off transport locks, remove and stow locks.
2. Set hitch to planting height.
3. Pull forward a few feet or just over a meter.
Height Mis-adjustment Risk:
Fully lower planter to field position (with openers into ground)
and set hitch height before making side-to-side adjustments.
4. Check tool bar height across planter. See page 104
for further detail and adjustment.

Marker Setup
Prior to first use, check and adjust:
•“Dual Marker Speed Adjustment” on page 149.
Prior to first use, and whenever changing row spacings,
set or reset:
•“Marker Extension” on page 150.
Prior to each planting session, check and adjust:
•“Marker Disc Adjustment” on page 59.
Fertilizer Drive Lock Up
Loss of Control and Sharp Object/Crushing Hazards:
Do not lift or lower wheel by spoke or rim; use handle only.
Keep feet out from under wheel. 90 pounds (41 kg) force is
required to lift wheel. If you lose your grip before pinning, or
after unpinning, the arm snaps down rapidly. The traction
teeth and the force of the wheel impact can inflict serious
injury.
The liquid fertilizer option uses a piston pump driven by a
ground contact wheel. When not using the fertilizer drive,
preserve the pump by locking up the ground wheel.
Equipment Damage Risks:
Never operate the pump dry. A continuous supply of fertilizer
or water is required. Dry operation damages the pump.
Refer to Figure 13
5. Remove clevis pin from storage hole .
6. Release the lock arm , lift handle to lift ground
wheel up to position it in-between lock arm.
7. Secure with pin clevis and cotter pin.

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
Perform the following steps before transporting the
YP4425A planter to the field.
❑ Carefully read “Important Safety Information” on
page 1.
❑ Install seed discs appropriate for crop. See
“Air-Pro® Meter Disc Installation” on page 77.
❑ Lubricate planter as indicated under “Lubrication”
on page 111.
❑ Check all tires for proper inflation. See “Tire
Inflation Chart” on page 134.
❑ Check all bolts, pins, and fasteners. Torque as
shown in “Torque Values Chart” on page 135.
❑ Check planter for worn or damaged parts. Repair or
replace parts before going to the field.
❑ Check hydraulic hoses, fittings, and cylinders for
leaks. Repair or replace before going to the field.
High Pressure Fluid Hazard:
Relieve 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. Escaping fluid under
pressure can have sufficient pressure to penetrate the skin
causing serious injury. If an accident occurs, seek immediate
medical assistance from a physician familiar with this type of
injury.
Fold/Unfold Lock Overview
The YP4425A planter includes five sets of locks for the
frame, wings and casters:
1. Wing locks: Hooks on the tongue engage locks on
the wings to prevent unfolding in transport. Tongue
must be raised to engage/release. See page 24.
2. Lift cylinder lock channels: These are
operator-installed on a raised plater, these prevent
lowering in transport or when parked. See page 27.
3. Fold cylinder and Caster swing arm cylinder lock
valves: Switch-controlled solenoid valves prevent
motion of the fold cylinders and caster swing arm
cylinders, in transport and field. See page 136.
4. Tongue lock: This engages automatically at unfold,
and lock the tongue/draw bar geometry for field
operations. See page 24.
5. Caster pivot locks: operator-engaged after unfold,
these prevent caster swiveling in the field, which aids
in tracking across hillsides. See page 29.

Unfolding the YP4425A Planter
The distance between the tractor and the seed structure
decreases by 12 feet (3.7 m) during unfolding. Planter,
tractor, or both will move during this operation.
Crushing, Pinch-Point and Overhead Hazards - To prevent
serious injury or death:
▲ Fold only on hard level ground. Allow ample room.
▲ If it is desired that the tractor not move, make sure tractor is
in Park and/or has parking brakes set, otherwise the
telescoping movement of the planter is likely to result in
tractor movement.
▲ Do not allow anyone to be on or near the planter during
unfolding.
▲ Stay clear of the wing sweep arcs. The sweep arcs of the
wings have numerous pinch and crush points in the
mechanism. Coulters and row openers are sharp.
▲ Allow no one near planter. The seed structure usually moves
forward during unfolding.
▲ Do not unfold with planter lowered, or machine damage
will result.
▲ Unfold only with markers resting in transport cradles.
▲ Unfold only if hydraulics are bled free of air and fully
charged with hydraulic oil.
1. Move to level ground.
Refer to Figure 15
2. On the Clutch Folding Module (CFM), set the
following switches to OFF (down):
MASTER switch in the CLUTCH cluster , and
Fert.Pump .
3. If the folded planter is lowered, raise mainframe (See
“Raising/Lowering Planter” on page 25).
4. If equipped with hydraulic hitch, the CFM Lift/Hitch
switch must be set to Hitch.
Refer to Figure 28
5. At each wing caster, check that lock control
handles and indicators are in the ROAD
position, allowing the casters to swivel. If they are
not, set handle to ROAD position and fully raise and
lower planter to release load on lock plates to allow
them to come open.
Refer to Figure 15

7. Raise tractor 3-point hitch or extend (raise) planter
hydraulic tongue until tongue wing locks rise and
disengage.
Machine Damage Risk:
Raise hitch before unfolding. If hitch is not raised, wing locks
will remain in transport hooks. Wings will not unfold, and
machine damage is possible.
8. Set CFM Marker/Fold switch to Fold. LED above

Machine Damage Risk:
Do not operate planter when unfolded unless tongue lock is
engaged. When unlocked, the pull bar system experiences
excess loads. The openers may be damaged by not tracking
straight forward.
11. When fully unfolded, set Marker/Fold hydraulic circuit
to Neutral.
12. For imminent lowered operations, remove lift cylinder
locks (see “Lift Cylinder Lock-Up” on page 27).
13. Set hitch height to planting position (“Raising/
Lowering Tongue” on page 17).
Machine Damage Risk:
Unfold and fold slowly. Adjust hydraulic flow to take a
minimum of 60 seconds to unfold or fold. Wings are massive,
and damage can occur if they reach the end of travel at high
speed. At lower speeds you also have time to check for hose
pinching or kinking, as well as react to anything unexpected in
the sweep arc.

Raising/Lowering Planter
General Raise/Lower Information
Planter raising/lowering relies on the four lift cylinders at
the mainframe and wing end gauge wheels.
The planter must be raised for folding and unfolding.
The planter will not lower if transport locks are installed.
See “Lift Cylinder Lock-Up” on page 27.
Note: An extended marker may drag or shove if left
extended during raise or lower operations. To avoid
this, fold markers prior to raise or lower.
Machine Damage Risk (Hydraulic Hitch Only):
Do not lower a folded planter without using the special
procedure on page 27 (this is a hitch-specific restriction - a
3-point folded planter may be lowered).
Figure 20
Clutch Folding Module
26113
Machine Damage Risk:
Do not lower while any planter folding operations are
underway or partially complete, with either hitch.
Machine Damage Risk:
Always raise the planter for any reverse/backing operations.
