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 6,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.

Wear Protective Equipment
Great Plains advises all users of chemical pesticides or
herbicides to use the following personal safety
equipment.
▲ Waterproof, wide-brimmed hat
▲ Waterproof apron.
▲ Face shield, goggles or full face respirator.
▲ Goggles with side shields or a full face respirator is
required if handling or applying dusts, wettable powders, or
granules or if being exposed to spray mist.
▲ Cartridge-type respirator approved for pesticide vapors
unless label specifies another type of respirator.
▲ Waterproof, unlined gloves. Neoprene gloves are
recommended.
▲ Cloth coveralls/outer clothing changed daily; waterproof
items if there is a chance of becoming wet with spray
▲ Waterproof boots or foot coverings
▲ Do not wear contaminated clothing. Wash protective
clothing and equipment with soap and water after each use.
Personal clothing must be laundered separately from
household articles.
▲ Clothing contaminated with certain pesticides must be
destroyed according to state and local regulations. Read
chemical label for specific instructions.
▲ Wear clothing and equipment appropriate for the job. Avoid
loose-fitting clothing.
▲ 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.
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.

401-626M Table of Contents Index 2014-02-10
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
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 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.
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.

4 YP2425A Table of Contents Index Great Plains Manufacturing, Inc.
Transport Machinery Safely
Maximum transport speed for implement is 20 mph (32
kph), 13 mph (22 kph) in turns. Some rough terrains
require a slower speed. Sudden braking can cause a
towed load to swerve and upset.
▲ Do not exceed 20 mph. 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.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when fully loaded, weighs
more than 1.5 times the weight of towing vehicle.
▲ Carry reflectors or flags to mark planter in case of
breakdown on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“Specifications and Capacities” on page 135.
▲ Do not fold or unfold the planter while the tractor is moving
Shutdown and Storage
▲ Lower planter, put tractor in park, turn off engine, and
remove the key7.
▲ Secure planter using blocks and supports provided.
▲ Detach and store planter in an area where children
normally do not play.
Tire Safety
Tire changing can be dangerous and should be
performed by trained personnel using correct tools and
equipment.
▲ When inflating tires, use a clip-on chuck and extension hose
long enough for you to stand to one side–not in front of or
over tire assembly. Use a safety cage if available.
▲ When removing and installing wheels, use wheel-handling
equipment adequate for weight involved.

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.

Hitching with 3-Point
Refer to Figure 6
4. Connect your tractor 3-point to the planter 3-point
hitch. If using quick hitch be sure planter locks into
hitch securely.
5. Raise tractor 3-point just enough to relieve pressure
off of the parking stand.
6. Store 3-point stands . There are two methods:
a. Remove lower pins . Swing stand under hitch.
Reinsert pin beneath stand at inner hole.
b. Remove both pins. Invert stand. Re-pin.
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.
7. Remove and store main tongue parking stand. See
“Store Main Parking Stand” on page 18.
8. Adjust the top link of a 3-point long enough so the
ball swivel does not bottom out when fully raised.

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. If you are having 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 30
2. Complete “Bleeding Hydraulics” on page 105.
3. Unfold the planter fully (page 24).
Set Tongue Height
Planter must be unfolded for this procedure.
Refer to Figure 12
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: Level frame in planting conditions.
Failure to do so may result in implement not
producing desired results.

Checking Planter Leveling Side to Side
The planter is designed to operate with all sections of the
main tool bar nominally 26in (66cm) 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 short distance.
Height Mis-adjustment Risk:
Fully lower planter to field position (with openers into ground)
and set hitch height before making side-to-side adjustments.

Wing/Center Level Check
Figure 13
26117
Great Plains Manufacturing, Inc. Table of Contents Index Preparation and Setup 21
Center Section Level Check
Vertical height and side-to-side level of the center section
is set at the factory and cannot be field-adjusted. It does
need to be verified before checking/adjusting the wings.
Soil accumulation on the wheels, for example, can cause
the center section to tilt.
Any unevenness in ground that tilts the wings or center
section causes the inner wing ends to move up or down
slightly with respect to the center frame.
Refer to Figure 13 on page 20
4. Measure the elevation of both left and right sides of
the planter center section, at the ends of the center
section tool bar (location in Figure 13).
1
Wing Leveling
Wing Leveling, Inboard End
Wing leveling check/adjustment is required prior to first
use of the YP2425A Planter, and periodically thereafter,
for example, if soil conditions change dramatically.
Before performing this operation:
• Check center section height and level (page 20).
• Row unit coulter/planting depths, and row unit
down-pressures must all be equal.
5. Measure the height of the inboard end of each wing,
near the wing flex pivot (location in Figure 13).
2
6. Compare this height to that of the center section
obtained at step 4 on page 21.
7. If the heights differ by more than 1in, check them
again after leveling the wing ends. If they still differ,
the thrust washers in the wing pivots may be worn
and in need of replacement.
3
Wing Leveling, Outboard End
Figure 14
Wing End Level Check

ground at the outer end of each wing (location in
Figure 14).
3
2
2. Compare to the measurement at the outer end of the
center tool bar, at the wing pivot location. All
measurements should be identical, and close to 26in
(66cm).
3. If measurements do not match, loosen upper gauge
wheel lock nut , and adjust eyebolt link length with
adjuster nut .

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. On
older models remove the chain.
Note: Do not operate planter pump when not applying
material.
Refer to Figure 16
For YP2425A planters:
1. Remove clevis pin from storage hole .
2. Release the lock arm , lift handle to lift ground
wheel up to position it in-between lock arm.
3. 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
YP2425A Planter to the field.
❑ Carefully read “Important Safety Information” on
page 1.
❑ Lubricate planter as indicated under “Lubrication”
on page 113.
❑ Check all tires for proper inflation. See
“Specifications and Capacities” on page 135.
❑ Check all bolts, pins, and fasteners. Torque as
shown in “Torque Values Chart” on page 150.
❑ 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.
❑ Install seed disks appropriate for crop. To change
disks, see “Air-Pro® Meter Disk Installation” on
page 78.
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 YP2425A 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 25.
2. Lift cylinder lock channels: These are
operator-installed on a raised plater, these prevent
lowering in transport or when parked. See page 30.
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 143.
4. Tongue lock: This engages automatically at unfold,
and lock the tongue/draw bar geometry for field
operations. See page 25.
5. Caster pivot locks: operator-engaged after unfold,
these prevent caster swiveling in the field, which aids
in tracking across hillsides. See page 24.

Unfolding the YP2425A 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 18
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 26).
4. If equipped with hydraulic hitch, the CFM Lift/Hitch
switch must be set to Hitch.
Refer to Figure 19
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 18
6. Set CFM Marker/Fold switch to Fold. LED above
switch blinks continuously.

Unfolding, Continued …
7. Raise tractor 3-point hitch or extend planter hydraulic
tongue until tongue wing locks rise and
disengage.
Machine Damage Risk:
Raise hitch before unfolding. If hitch is not raised, wing locks
remain in transport hooks. Wings cannot unfold, and machine
damage is possible.
8. Activate (normally Retract) tractor hydraulic circuit to
unfold wings.
Refer to Figure 22

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.
10. When fully unfolded, set Marker/Fold hydraulic circuit
to Neutral.
11. Disable lock valve solenoids by setting CFM
Marker/Fold switch to Marker.
Note: Set switch to “Marker” even if markers are not
installed.
12. For imminent lowered operations, remove lift cylinder
locks (see “Lift Cylinder Lock-Up” on page 30).
Refer to Figure 19
13. For operations across hillsides, engage caster locks.
Set wire handles to FIELD. Casters will lock into
straight trailing position during operation.
14. Set hitch height to planting position
(“Raising/Lowering Tongue” on page 18).
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
Refer to Figure 23
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 fully lower if transport locks are
installed. See “Lift Cylinder Lock-Up” on page 30.
Note: When unfolded, if one or both markers are
extended, they 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 planter while folded without using the special
procedure below (this is a hydraulic hitch restriction - planter
may be lowered while folded with standard 3-point hitch).
Figure 23
Clutch Folding Module
1
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.
Local Float on Hydraulic Tongue
A hydraulic hitch planter may be raised or lowered while
folded if the hitch has the local float valve.
Crushing Hazard:
Tongue or planter components may drop suddenly when circuit
is floated. Before raising or lowering, set CFM Lift/Hitch
switch to Hitch and set tractor circuit to Float. If tractor is not
available, use bypass valve on hitch.
Stand clear and open it slowly.
1. Float hitch circuit before lowering while folded.
Float hitch circuit before rasing while folded.
2. Set CFM Lift/Hitch switch to Lift for raising/lowering.
3. Close bypass valve before switching to Hitch. Hitch
circuit operation has no effect with bypass valve
open.
