Remove buildup of grease, oil, or
debris.
Always make sure any material and
waste products from the repair and
maintenance of the implement are
properly collected and disposed.
Remove all tools and unused parts
from equipment before operation.
Do not weld or torch on galvanized
metal as it will release toxic fumes.
Use A Safety Chain
A safety chain will help control
drawn machinery should it
separate from the tractor drawbar.
Use a chain with the strength
rating equal to or greater than the
gross weight of the towed
implement.
Attach the chain to the tractor
drawbar support or other specified
anchor location. Allow only
enough slack in the chain to
permit turning.
Always hitch the implement to the
machine towing it. Do not use the
safety chain to tow the implement.
Tire Safety
Tire changing
can be
dangerous
and must be
performed by
trained personnel using the
correct tools and equipment.
Always properly match the wheel
size to the properly sized tire.
Always maintain correct tire
pressure. Do not inflate tires
above recommended pressures
shown in the Operator’s Manual.
When inflating tires, use a clip-on
chuck and extension hose long
enough to allow you to stand to
one side and NOT in front of or
over the tire assembly. Use a
safety cage if available.
Securely support the implement
when changing a wheel.
When removing and installing

trailer to swerve unexpectedly.
Reduce speed if towed trailer is not
equipped with brakes.
Avoid contact with any overhead
utility lines or electrically charged
conductors.
Always drive with load on end of
loader arms low to the ground.
Always drive straight up and down
steep inclines with heavy end of
skid steer on the “uphill” side.
Engage park brake when stopped
on an incline.
Maximum transport speed for an
attached equipment is 20 mph
(32 km/h). DO NOT EXCEED.
Never travel at a speed which does
not allow adequate control of
steering and stopping. Some rough
terrains require a slower speed.
As a guideline, use the following
maximum speed weight ratios for
attached equipment:
20 mph (32 km/h) when weight
of attached equipment is less
than or equal to the weight of
machine towing the equipment.
10 mph (16 km/h) when weight of
attached equipment exceeds
weight of machine towing
equipment but not more than
double the weight.
IMPORTANT: Do not tow a load
that is more than double the weight
of the vehicle towing the load.

Important Safety Information

Listed below are common practices that may or may not be applicable to the products
described in this manual.
Use Seat Belt and ROPS
Great Plains recommends the use
of a CAB or roll-over-protective-
structures (ROPS) and seat belt
in almost all power machines.
Combination of a CAB or ROPS
and seat belt will reduce the risk
of serious injury or death if the
power machine should be upset.
If ROPS is in the locked-up
position, fasten seat belt snugly
and securely to help protect
against serious injury or death
from falling and machine overturn.
Keep Riders Off
Machinery
Never carry riders on the tractor or
implement.
Riders obstruct operator’s view
and interfere with the control of
the power machine.
Riders can be struck by objects or
thrown from the equipment.
Never use the tractor or
implement to lift or transport
riders.
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 the phone.
911
Use Safety
Lights and Devices
A slow moving power machine
can create a hazard when driven
on public roads. They are difficult
to see, especially at night. Use the
Slow Moving Vehicle (SMV) sign
when on public roads.
Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
Avoid High Pressure
Fluids
Escaping fluid
under pressure will
penetrate the skin or
eyes causing serious injury.
Relieve all residual pressure
before disconnecting hydraulic
lines or performing work on the
hydraulic system.
Make sure all hydraulic fluid
connections are properly
tightened/torqued and all
hydraulic hoses and lines are in
good condition before applying
pressure to the system.
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.
DO NOT DELAY. If an accident
occurs, seek immediate
emergency medical care or
gangrene may result.
Wear Personal Protective
Equipment (PPE)
Wear protective clothing and
equipment appropriate for the job
such as safety shoes, safety,
glasses, hard hat, dust mask,
and ear plugs.
Clothing should fit snug without
fringes and pull strings to avoid
entanglement with moving parts.
Prolonged exposure to loud noise
can cause hearing impairment or
hearing loss. Wear suitable
hearing protection such as
earmuffs or earplugs.
Operating a machine safely

Dig Safe - Avoid
Underground Utilities
USA: Call 811
CAN: digsafecanada.ca
Always contact your local utility
companies (electrical, telephone,
gas, water, sewer, and others)
before digging so that they may
mark the location of any
underground services in the area.
Be sure to ask how close you can
work to the marks they positioned.
Listed below are common practices that may or may not be applicable to the products
described in this manual.
Avoid crystalline Silica
(quartz) Dust
Because crystalline silica is a basic
component of sand and granite,
many activities at construction sites
produce dust containing crystalline
silica. Trenching, sawing, and boring
of material containing crystalline
silica can produce dust containing
crystalline silica particles. This dust
can cause serious injury to the
lungs (silicosis).
There are guidelines which should
be followed if crystalline silica
(quartz) is present in the dust.
Be aware of and follow OSHA
(or other local, State, or Federal)
guidelines for exposure to airborne
crystalline silica.
Know the work operations where
exposure to crystalline silica may
occur.
Participate in air monitoring or
training programs offered by the
employer.
Be aware of and use optional
equipment controls such as water
sprays, local exhaust ventilation,
and enclosed cabs with positive
pressure air conditioning if the
machine has such equipment.
Otherwise respirators shall be worn.
Where respirators are required, wear
a respirator approved for protection
against crystalline silica containing
dust. Do not alter respirator in any
way. Workers who use tight-fitting
respirators can not have beards/
mustaches which interfere with the
respirator seal to the face.
If possible, change into disposable
or washable work clothes at the
work site; shower and change into
clean clothing before leaving the
work site.
Do not eat, drink, use tobacco
products, or apply cosmetics in
areas where there is dust containing
crystalline silica.
Store food, drink, and personal
belongings away from the work
area.
Wash hands and face before eating,
drinking, smoking, or applying
cosmetics after leaving the exposure
area.
Handle
Chemicals Properly
Protective clothing should be
worn.
Handle all chemicals with care.
Follow instructions on container
label.
Agricultural chemicals can be
dangerous. Improper use can
seriously injure persons, animals,
plants, soil, and property.
Inhaling smoke from any type of
chemical fire can be a serious
health hazard.
Store or dispose of unused
chemicals as specified by the
chemical manufacturer.

•Lightweight tractors with rear attached implements may
need weights added to the front to maintain steering
control. Consult your tractor Operator’s Manual to
determine weight requirements and maximum limitations.
Make certain tractor’s 3-point lifting capacity and weight
is capable of lifting and controlling the seeder under all
operating conditions. Refer to “Specifications &

Sling Bracket
Refer to Figure 1-3:
The sling brackets on the grass seedbox provide lifting
points for hooking lift chains (#1) and lifting the Multi-
Purpose Seeder off the ground. The chains should be
hooked to a spreader bar vertically above the grass
seedbox sling brackets. Make sure lift chains (#1) stay
vertical while lifting the seeder.
Flex Guard Hose
Refer to Figure 1-3:
Remove all flex guard hoses (#2) mounted on the rear
roller scraper and discard.
IMPORTANT:
Reference Figure 1-2: Using lift chains that pull at an
angle to the sling brackets will bend the brackets and
can damage the seedbox.
Reference Figure 1-3: Always use a spreader bar to
keep lift chains vertical while lifting the seeder off the
ground.
