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.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This planter requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
▲ Avoid the hazard by relieving pressure at other remotes, and
shutting down tractor before connecting, disconnecting or
inspecting 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.
401-651M Table of Contents Index 2014-08-15
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Use A Safety 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 specified
anchor location. Allow only enough slack in chain for turns.
▲ Replace chain if any links or end fittings are broken,
stretched or damaged.
▲ Do not use safety chain for towing.
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.
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.
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 128.
▲ Do not fold or unfold the planter while the tractor is
moving.

Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections.
Only trained personnel should work with system hydraulics.
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.
Use paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems.
Refer to Figure 6
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.

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 feeds 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 line,
which returns hydraulic fluid from the fan motor case.

Figure 10
Setting Tool Bar Height
Refer to Figure 10
During initial setup and periodically throughout the
season, check that the planter runs level. When planting,
the top of the main frame should be parallel to the
ground.
To level the planter, the distance from bottom of the
mainframe tube to the ground, must be:
26 inches (66 cm)
1
with the planter lowered into planting position.
With the openers in the ground, this tool bar height
normally requires a hitch height of:
141⁄2inches (36.8 cm)
2
measured from the bottom of the tongue to the ground.
Refer to Figure 11 (showing one of two hitch bolts)
To obtain the correct height, remove the two hitch
bolts , and reposition the planter hitch on the tongue.
3 4
Sudden Hitch Slump or Failure Risks:
Always have two bolts through two holes on both hitch and
tongue. Never rely on a single bolt.
The hitch can be inverted in the tongue for extreme
height changes.

Wheel Adjustment for Leveling
Refer to Figure 12
If the target tool bar height cannot be achieved with the
frame level, an adjustment can be made by relocating
the wheel axles in the arms. This lowers the planter by
about 2 inches (5.1cm).
Block up the frame to remove weight from tires. Remove
bolts , located in lower holes, securing transport
5
ground tire assembly to unit. Move wheel assembly and
secure assembly to upper hole using previously
removed bolt.

Monitor Setup
Refer to Figure 34
The standard DICKEY-john® PM300 system monitors
the following elements of a YP425A, YP625A and
YP825A planter:
• Seeds at each row unit seed tube.
• Ground speed.
See “Seed Monitor Console Installation” on page 163.
Refer to the DICKEY-john® PM300/PM332/PM400
Operator’s Manual for monitor operations.
After installation, and prior to first field use, the monitor
must be setup with the row spacing and speed sensor
constant, as well as your preferences for information
display. Row count is auto-assigned, but any other
factory defaults are not likely to be correct for your
planter.
Row spacing data may be found in the Appendix.
For speed setup, Great Plains recommends using the
400-foot calibration described in the DICKEY-john
manual, rather than using a theoretical “# of pulses”.
Perform the calibration run in representative field
conditions, as soil conditions, surface looseness and
other tillage practices can cause variations in the
effective rolling radius of the ground drive wheel.
Prior to each planting session, set any desired limits for
speed and population for the current crop.

Loss of Control and Crushing Hazards:
Lift or lower wheel by using ground blocks and planter
hydraulics. Use blocks that are stable front to back and side to
side to avoid the possibility of the wheel turning. Keep feet out
from under wheel. 90 pounds (41 kg) force is required to lift
wheel. If blocks are removed before pinning, or after
unpinning, the arm snaps down rapidly. 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.
Refer to Figure 15
For YP425/625/825A planters:
5. Remove clevis pin from storage hole
6. To compress spring and allow the ground drive
wheel to raise up, place blocks under the ground
wheel .
7. Lower the planter.
8. Align matching plate holes and insert pin . Secure
with 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
YP425A/625A/825A planter to the field.
❑ Carefully read “Important Safety Information” on
page 1.
❑ Fertilizer Option: Review the application instructions
and Material Safety Data Sheet (MSDS) for the
fertilizer(s).
❑ Install seed disks appropriate for crop. See
“Air-Pro® Meter Disk Installation” on page 76.
❑ Lubricate planter as indicated under “Lubrication”
on page 110.
❑ Check all tires for proper inflation. See “Tire
Inflation Chart” on page 137.
❑ Check all bolts, pins, and fasteners. Torque as
shown in “Torque Values Chart” on page 137.
❑ 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 and shut down tractor before connecting,
disconnecting or checking 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.

Raising/Lowering Planter
Refer to Figure 16
Planter raising and lowering relies on two or four lift
cylinders . To raise or lower the planter, move the lever
for the Lift circuit.
Gradual Crushing Hazard:
Do not rely on hydraulic pressure alone to keep the planter
raised. Use transport/lift locks (page 23) when working
around a raised planter. The bypass orifices in the re-phasing
system cause it to slowly lower.
1
Re-Phasing Lift System
In typical use during a single planting operation, it is
normal for the lift cylinders to get out of phase, resulting
in uneven raising and lowering of the planter.
Every 8 to 10 passes, re-phase the cylinders with this
procedure:
1. Raise the planter completely, and hold the hydraulic
lever or switch for several seconds after the planter
reaches full raised position, or until all cylinders are
fully extended.
2. When all cylinders are fully extended, momentarily
reverse (Retract) the control to lower the planter
1
⁄2inch (12 mm).
Figure 16
Planter Lift System
Machine Damage Risks:
Always fold markers (page 45) before raising or lowering.
Disengage transport locks (page 23) before lowering.
Always raise the planter for any reverse/backing.
Except on pavement, begin forward motion before lowering, as
rows move backward slightly as arms swing up.

Transport
Loss of Control Hazard:
Never tow an implement that weighs more than 150% of the
tractor. Ensure that the towing vehicle is adequate for the task.
Using an inadequate tow vehicle is extremely unsafe, and can
result in loss of control, serious injury and death.
The planter can weigh over 16 000 pounds (7300 kg),
depending on configuration and seed load. The tractor MUST
be rated for the load and must weigh at least 67% of the load.
If the tractor is not rated for at least 16 000 lbs, calculate or
obtain a scale weight of the planter. See chart below for
typical configuration weights.
Do not tow if planter exceeds the load rating of the vehicle.
Braking and Loss of Control Hazard:
Do not exceed 20 mph (32 kph).
Reduction of Control Risk:
Seed and fertilizer may be loaded prior to travel, but increase
stopping distance, increase the need for caution in turns and
braking, and increase tire wear.

Transport Steps
Transport only with markers stowed (page 45).
1. Check that planter is securely hitched to a sufficient
tractor (page 14).
2. Always use a locking-style hitch pin sized to match
holes in hitch and draw-bar (minimum
1-inch-diameter, heat-treated pin).
3. Attach safety chain to tractor with enough slack to
permit turning (page 14).
4. Verify correct operation of lights.
5. Fold markers if unfolded (Option, page 45).
6. Raise planter (page 22).
7. Install cylinder locks (page 23).
8. Unload hoppers and tank(s) before transporting if at
all possible. The planter can be transported with a
full material load, but the added weight increases
stopping distance and decreases maneuverability.
Increased Hazards and Wear Risks:
Seed may be loaded prior to travel, but increases stopping
distance, increases the need for caution in turns and braking,
and increases tire wear.
9. If any seed is in hoppers or delivery hoses, close
seed inlet shutters at meters (page 77).
10. Check that tires are properly inflated (page 137).
11. Plan the route. Avoid steep hills.
12. Always have lights on for highway operation.
13. Do not exceed 32 kph (20 mph). Comply with all
national, regional and local laws when traveling on
public roads.
14. Remember that the planter may be wider than the
tractor. Allow safe clearance.
15. Transport slowly over uneven or rough terrain.
