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.
Wear Protective Equipment
Wear clothing and equipment appropriate for the job.
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.

Great Plains | 411-332M | 2019-02-19 Table of Contents Index 2
3P3025AH Table of Contents Index Important Safety Information
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 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.

3P3025AH Table of Contents Index Important Safety Information
Great Plains | 411-332M | 2019-02-19 Table of Contents Index 3
Transport Machinery Safely
Maximum transport speed for planter is 20 mph (32 kph).
Some rough terrains require a slower speed. Sudden
braking can cause a towed load to swerve and upset.
Do not exceed 20 mph (32 km/h). 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.
Do not exceed 13 mph (21 km/h) in turns. The weight of
the planter can cause under-steer, and the height of the
planter is a tipping hazard.
Comply with state and local laws.
Do not tow an planter unless the towing vehicle is rated
for, and ballasted for, the weight of the planter.
Carry reflectors or flags to mark planter in case of
breakdown on the road.
Do not fold or unfold the planter while the tractor is
moving.
Check for Overhead Lines
The planter requires at least 15 feet (4.5 m) vertical
clearance in transport. Contacting overhead electrical
lines can introduce lethal voltage levels on planter and
tractor frames. A person touching almost any metal part
can complete the circuit to ground, resulting in serious
injury or death. At higher voltages, electrocution can
occur without direct line or body contact.
Avoid overhead lines during folding, unfolding, transport
and parking.
Shutdown and Storage
Lower planter, put tractor in park, turn off engine, and
remove the key.
Secure planter using blocks and supports provided.
Detach and store planter in an area where children
normally do not play.

Great Plains | 411-332M | 2019-02-19 Table of Contents Index 4
3P3025AH Table of Contents Index Important Safety Information
Practice Safe Maintenance
Understand procedure before doing work. Use proper
tools and equipment. Refer to this manual for additional
information.
Work in a clean, dry area.
Lower the planter, put tractor in park, turn off engine, and
remove key before performing maintenance.
Make sure all system pressure is relieved.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on planter.
Inspect all parts. Make sure parts are in good condition
and installed properly.
Remove buildup of grease, oil or debris.
Remove all tools and unused parts from planter before
operation.
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
Be familiar with all planter functions.
Operate machinery from the driver’s seat only.
Do not leave planter unattended with tractor engine
running.
Do not dismount a moving tractor. Dismounting a moving
tractor could cause serious injury or death.
Do not stand between the tractor and planter during
hitching.
Keep hands, feet and clothing away from moving parts.
Watch out for wires, trees, etc., when folding and raising
planter. Make sure all persons are clear of working area.

Safety Decals
Safety Reflectors and Decals
Your implement comes equipped with all lights, safety
reflectors and decals in place. They were designed to
help you safely operate your implement.
Read and follow decal directions.
Keep lights in operating condition.
Keep all safety decals clean and legible.
Replace all damaged or missing decals. Order new decals
from your Great Plains dealer. Refer to this section for
proper decal placement.
When ordering new parts or components, also request
corresponding safety decals.

Hitching to Tractor
Refer to Figure 3
This planter can come installed with either a universal
category III and IV hitch or unchangeable category IV wide
hitch. Both require a tractor with a quick attach hitch.
You can off-center the planter’s hitch alignment by
adding or removing hardware. See “Lower Link
Adjustments”.
Crushing Hazard:
Do not stand or place any part of your body between the
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 making hitch
adjustments and connections.
If changing the category of a universal hitch, a top and
lower link adjustment are required.
Top Link Adjustments
Make a top link (1) adjustment only if changing the
category of hitch or after adding lift assist to machine.
Planters without lift assist must use a category IV hitch.
Lift Assist
For planters without lift assist, place pin in specified hole
(A). Planters with lift assist do not place a pin in hole (A).
Gauge Wheel Settings
For planters using a category III hitch with rear mounted
gauge wheels, install stop plate (2) with pin through hole (D).
For planters using a category IV hitch with rear mounted
gauge wheels, install stop plate (2) with pin through hole (E).
NOTE: The stop plate (2) is not used on planters with
front mounted gauge wheels.
Lower Link Adjustments
Make a lower link (3) adjustment only if changing the
category of hitch or offsetting hitch tractor alignment.
Altering Hitch Category
Changing the hitch category requires reconfiguring shims
and other hardware used. Refer to “Hitch Configurations”
on page 123 for layouts of different hitch categories.
Offsetting Hitch Alignment
For planting on beds, you may desire a slight off-centering of the
machine. To do so, unhitch tractor hooks from couplings, and
then separate the round shim (5) from the spacer (6) by moving
it to the opposite side of the pin (7) as shown in Figure 5.
If more than 1/2” of off-centering is desired or hitch is category III
narrow, move additional available slide-out shims (4) from
mounting plate (A) and reinstall them against opposite
inside-facing surface of mounting plate (B) as shown. Move no
more than 1” of shims from the default category hitch
configurations shown on page 123.
