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.
401-923M Table of Contents Index 2014-06-17
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 130.
▲ 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.

Figure 8
Setting Tool Bar Height
Front to Back
Refer to Figure 8
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:
77.2 cm (303⁄8inches) with the planter lowered into
planting position.
With the openers in the ground, this tool bar height
normally requires a hitch height of:
36.8 cm (141⁄2inches) measured from the bottom of the
tongue side plates to the ground.
Refer to Figure 9 (showing one of two hitch bolts)
To obtain the correct height, remove the two hitch
bolts , and reposition the planter hitch on the tongue.

Loss of Control Hazard:
Always re-secure the safety chain with one of the hitch bolts.
Use the heavy-duty flat washer under the head of that bolt.
An unsecured or inadequately secured chain may fail when
needed, resulting in an unhitched, uncontrolled planter moving
on the highway. Major equipment damage is certain. Serious
injury or death could result.
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.

Side to Side (Left to Right)
This planter is also equipped with a system to level the
main frame parallel to the axle.
While the planter is factory-leveled at the time of
assembly, some misalignment may occur during shipping
and/or transport.
Note: It is easier to perform this operation with the planter
unfolded and in the fully-raised position.
1. Measure the distance from the main frame to the
axle on both sides of the planter as far from the
center as possible, but equidistant from the center.
These distances must be equal in order for the
planter to plant evenly, and are approximately
133.6 cm (521⁄8inches) with the planter fully raised.
If the distance is not the same from one side to the
other, use the following procedure to correct this.
2. Loosen the ten, 1 inch bolts holding the pin
support plates on both sides.
3. Loosen the jam nuts on each of the four,3⁄4inch
set screws located at the top and bottom of each
of the pin support plates.

Lock Up Fertilizer Drive
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.
Refer to Figure 13
1. Remove clevis pin from storage hole
2. To compress spring and allow the ground drive
wheel to raise up, place blocks under the ground
wheel .
3. Lower the planter.
4. 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
YP825AR 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
and Scheduled Maintenance” on page 108.
❑ 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 134.
❑ 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.
401-923M Table of Contents Index 2014-06-17
Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 23
Transport
Loss of Control Hazard:
Never tow an implement that weighs more than 150% of the
tractor. Check your numbers. This planter is quite heavy for its
size. 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 nearly 23000 pounds (10500 kg),
depending on configuration and material 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 23000 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.
Tipping Hazard and Excess Wear Risk:
Do not load seed or fertilizer prior to travel. This elevates the
center of gravity of the folded planter, increasing the chance of
tipping in turns. Avoid steep highway shoulders. When
materials are loaded, raise only to field lift height for field
turns and short moves. Do not traverse steep slopes at
transport lift. Transport with material loaded also causes
excess wear on the pivot bearing. Some planter configurations,
with material loaded, exceed the highway rating of the gauge
wheel tires.
Braking and Loss of Control Hazard:
Do not exceed 20 mph (32 kph).

2. Always use a locking-style hitch pin sized to match
holes in hitch and draw-bar (minimum 1 inch / 2.5 cm
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 50).
6. Fold planter (page 35).
7. Unload hoppers and tank(s) before transporting.
8. If any seed is in hoppers or delivery hoses, close
seed inlet shutters at meters (page 78).
9. Check that tires are properly inflated (page 134).
10. Plan the route. Avoid steep hills.
11. Always have lights on for highway operation.
12. Do not exceed 32 kph (20 mph). Comply with all
national, regional and local laws when traveling on
public roads.
13. Remember that the planter may be wider than the
tractor. Allow safe clearance.
14. Transport slowly in turns, over uneven or rough
terrain.

About the Frame Control Switch
Two planter hydraulic circuits (lift/lift-lock/marker and
rotate/frame-lock/telescope) have multiple cylinders
sharing the circuit.
Which cylinder set has the circuit is controlled by a
switch box in the tractor cab, a solenoid valve block on
the planter, and limit switches on the planter.
Refer to Figure 14

Set circuit tractor remotes to Neutral before activating
switches. Do not operate solenoid valvesb under
pressure.
Instruction steps have only one switch out of “OFF”
position at a time.
The planter limit switches prevent most, but not all
incorrect operations. Follow instruction steps carefully.
Do not rely on the protection of limit switchesbfor routine
operations.
The solenoid valves are spring-loaded to OFF. If power is
off, or harnesses are not connected at the hitch, normal
hydraulic operations are not possible.
a. If no markers are installed, or the marker shut-off valve (page 26) is closed, OFF locks lift cylinder motion. If markers are installed, with
manual shut-off valve on, lift/marker motion is still possible with the LIFT switch (or POWER) OFF. See page 26 for details.
b. Exception: the LIFT solenoid valve is designed to cut off active flow to the lift/lift-lock/marker circuit during field (HALF) lift.

About the Marker Shut-Off Valve
Refer to Figure 15
This valve is only present on planters equipped with
optional field markers. It is located on the right side of the
lift structure.
The marker hydraulic circuit is shared with the lift circuit.
Unless disabled by the shut-off valve, a marker retracts
during lift, and the other side extends during lower.
Refer to Figure 16
This shut-off valve, when closed, prevents marker
extension or retraction. Markers must be disabled by this
valve during planter fold, and during field operations not
requiring use of markers.
When the shut-off valve is open, any lift operation results
in folding of any extended marker. When the shut-off
valve is open, any lowering operation results in extension
of a marker on the alternate side, based on the internal
state of the marker sequence valve.

Figure 15
Marker Shut-Off Location
34796
Frame and Overhead Crushing Hazards:
• Never open the shut-off valve with the frame raised.
• Never close the valve under a raised and unlocked frame.
• Never close the valve with a marker extended.
When the shut-off valve is open, the marker circuit is plumbed
in parallel with the lift circuit at all times. An equipment
malfunction could result in unexpected frame and/or marker
motion in some situations. You could be under the frame
operating the valve in some of those situations. Serious injury,
death, and/or substantial property damage can result.
Depending on the internal state of the sequence valve,
if the opener frame is raised and not locked up, and the
shut-off valve is opened, frame weight may force oil from
lift cylinders to marker cylinders, possibly resulting in:
▲ unexpected frame lowering, and
▲ simultaneous unexpected marker extension.
This could happen with hydraulics off (or disconnected)
and all frame control switches off.
If the opener frame is raised and is locked up, and the
valve is open, unexpected marker extension does occur
during lowering from transport lift. This a potentially
hazardous situation.
If the valve is closed with a marker partially or fully
extended, the marker cannot fold during lift, and if the lift
is prematurely stopped, the valve state is changed, and
the lift reversed, there is some chance of having two
markers extended. See “Dual Marker Operations” on
page 36.
