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.

2018-07-24 Table of Contents Index 401-312M
3PYP Table of Contents Index Important Safety Information 2
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.
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.
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.
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.

3PYP Table of Contents Index Important Safety Information 3
2018-07-24 Table of Contents Index 401-312M
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.
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

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.
3-Point Hitching
Refer to Figure 4
For older planters with row mode spacers, see “Hitching
with Row Mode Spacer” on page 160.
The left arm of the tractor 3-point hitch is secured and
prevented from shifting laterally. The right arm is
allowed to float on the pin.
The objective is to align the planter center-line with the
tractor center-line.
1. The planter includes several spacers to position and
secure the left arm of the 3-point hitch:
1 401-630H SPACER 3 PT 1 1/2 X 2
2 411-442D LOWER 3PT PIN SPACER 1/2 THK
5 411-448D LOWER 3PT PIN SPACER 1/4 THK
1 411-449D TUBE 3" X 1 1/2" X 1/2" LONG
2. The tube spacers ( and ) are always used, and
are typically positioned on the right and left of the
tractor hitch arm.
3. Insert open-end spacers ( and ) to the left of
the smaller tube spacer to achieve center-line
alignment. The following table has recommendations
for specific tractors.
4. Add a combination of the remaining spacers to
eliminate any slack space on the pin, and minimize
side-to-side play during operations.
5. Secure both sets of spacers with the provided 1/2-13
bolts, lock washers and nuts.

Refer to Figure 5
6. Connect your lower tractor 3-point arms to the
planter 3-point hitch. If using quick hitch be sure
planter locks into hitch securely.
This is a semi-mounted implement.
•Older models have no top link .
•2007+ models have a flexible top link which may be
used, with care, in certain situations.
•If the top link is not used, you may optionally use
lift-assist weight transfer to apply some of the cart
weight to the openers during planting.
Refer to Figure 6
If using lift-assist weight-transfer (and not using the
3-point top link), make sure the parallel arms are
configured as follows:
7. Install the lift-assist weight-transfer pins . The pins
are stored in a plate behind the cart parallel arm
pivot weldment. Install them in the large holes at the
bottom of the rod-end lug in the frame-to-cart parallel
arms.
8. Remove the lift-assist shear bolts from the small
holes below the lift-assist rod-end lug upper pivot
pin. Store the bolts in the plates behind the cart
parallel arm pivot weldments.
If using the 3-point top link, make sure the parallel arms
are configured as follows:
9. Install the lift-assist shear bolts. Spare bolts are
stored in a plate behind the cart parallel arm pivot
weldment. Secure the bolt in the small hole below
the lift-assist rod-end lug upper pivot pin.
10. Remove the lift-assist weight-transfer pins . These
are located at the bottom of the rod-end lug in the
frame-to-cart parallel arms. The pin is stored in a
plate behind the cart parallel arm pivot weldment.
Refer to Figure 5
11. Connect the flexible top link only for field
operations and maintenance (never for transport).
Adjust the top link with the tractor turnbuckle and the
sliding link .
For field operations, adjust the top link so that it is
slack with the planter lowered, and taut near the top
of hitch travel with the planter raised. The goal is to
reduce the weight borne by the rear lift assist
cylinders, and reduce any tendency for the tires to
dig on end-of-pass turns and during backing.
12. Raise tractor 3-point just enough to relieve pressure
from the bases of the parking stands.
Excess 3-point weight and steering hazard:
Do not use the top-link and weight-transfer capabilities at the
same time. Planter caster wheels may lift off ground. Tractor
steering wheels may lose effectiveness. An accident is possible,
resulting in serious injury or death, and planter damage.

Electrical Hookup
Refer to Figure 7
Your 3PYP is equipped with several standard and
optional devices that require separate electrical
connections. For future reference, note any optional
connections on this checklist.
Make sure tractor is shut down with accessory power off
before making connections.
These connections may be made in any order. The key
requirement is that all connections be made prior to
planter movement.
Switch control boxes should be mounted in your
tractor cab in a location with easy access. Route
wiring harnesses with enough slack to allow for tractor
movement, especially on articulating tractors.

Hydraulic Hose Hookup
Only trained personnel should work on system hydraulics!
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
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
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.
Refer to Figure 8
Great Plains hydraulic hoses are 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.
Current Style Color Coded Hose Handles
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 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.
