Safety
• Inspect the area where the equipment is to be
used and remove all rocks, toys, sticks, wires,
bones, and other foreign objects which can be
thrown by the machine and may cause personal
injury to the operator or bystanders.
DANGER
In certain conditions during fueling, static
electricity can be released causing a spark
which can ignite gasoline vapors. A fire or
explosion from gasoline can burn you and
others and cause property damage.
DANGER
In certain conditions gasoline is extremely
flammable and vapors are explosive.
• Always place gasoline containers on the
ground away from your vehicle before
filling.
A fire or explosion from gasoline can burn
you, others, and cause property damage.
• Do Not fill gasoline containers inside a
vehicle or on a truck or trailer bed because
interior carpets or plastic truck bed liners
may insulate the container and slow the
loss of any static charge.
• Fill the fuel tank outdoors on level ground,
in an open area, when the engine is cold.
Wipe up any gasoline that spills.
• Never refill the fuel tank or drain the
machine indoors or inside an enclosed
trailer.
• When practical, remove gas-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on
the ground.
• Do Not fill the fuel tank completely full.
Fill the fuel tank to the bottom of the filler
neck. The empty space in the tank allows
gasoline to expand. Overfilling may result
in fuel leakage or damage to the engine
or emission system.
• If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
gasoline dispenser nozzle.
• If a gasoline dispenser nozzle must be
used, keep the nozzle in contact with the
rim of the fuel tank or container opening
at all times until fueling is complete.
• Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by spark.
• Store gasoline in an approved container
and keep it out of the reach of children.
WARNING
• Add fuel before starting the engine. Never
remove the cap of the fuel tank or add
fuel when engine is running or when the
engine is hot.
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors has caused
cancer in laboratory animals. Failure to use
caution may cause serious injury or illness.
• If fuel is spilled, Do Not attempt to start
the engine. Move away from the area of
the spill and avoid creating any source of
ignition until fuel vapors have dissipated.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas
tank/container opening.
• Do Not operate without entire exhaust
system in place and in proper working
condition.
• Keep away from eyes and skin.
• Never siphon by mouth.
• Check that the operator's presence controls,
safety switches, and shields are attached and
functioning properly. Do Not operate unless they
are functioning properly.

Safety
• Be aware that operating on wet grass, across steep
slopes or downhill may cause the mower to lose
traction. Loss of traction to the drive wheels may
result in sliding and a loss of braking and steering.
DANGER
Operating on wet grass or steep slopes can cause
sliding and loss of control. Wheels dropping over
edges, ditches, steep banks, or water can cause
rollovers, which may result in serious injury,
death or drowning.
• Always avoid sudden starting or stopping on a
slope. If tires lose traction, disengage the blades
and proceed slowly off the slope.
• Do Not mow slopes when grass is wet.
• Do Not mow near drop-offs or near water.
• Do Not mow slopes greater than 15 degrees.
• Follow the manufacturer’s recommendations for
wheel weights or counter weights to improve
stability.
• Reduce speed and use extreme caution on
slopes.
• Use extreme care with grass catchers or
attachments. These can change the stability of the
machine and cause loss of control.
• Avoid sudden turns or rapid speed changes.
• Keep the roll bar in the raised and locked
position and use seat belt.
Using the Rollover Protection System
(ROPS)

Operation
8. Torque the 3/8–16 whizlock nut to 27-33 ft-lb
WARNING
Loading a unit on a trailer or truck increases
the possibility of backward tip-over. Backward
tip-over could cause serious injury or death.
9. Torque the 3/8 nyloc nut to 27-33 ft-lb (37-45
N-m).
• Use extreme caution when operating a unit
on a ramp.
• Use only a single, full width ramp; Do Not
use individual ramps for each side of the unit.
• If individual ramps must be used, use enough
ramps to create an unbroken ramp surface
wider than the unit.
• Do Not exceed a 15° angle between ramp and
ground or between ramp and trailer or truck.
• Avoid sudden acceleration while driving unit
up a ramp to avoid tipping backward.

Loading a Unit
Use extreme caution when loading units on trailers or
trucks. One full width ramp that is wide enough to
extend beyond the rear tires is recommended instead
of individual ramps for each side of the unit. The
lower rear section of the tractor frame extends back
between the rear wheels and serves as a stop for
tipping backward. Having a full width ramp provides
a surface for the frame members to contact if the
unit starts to tip backward. If it is not possible to use
one full width ramp, use enough individual ramps to
simulate a full width continuous ramp.
Transporting
Transporting a Unit
Use a heavy-duty trailer or truck to transport the
machine. Lock brake and block wheels. Securely
fasten the machine to the trailer or truck with straps,
chains, cable, or ropes. Be sure that the trailer or truck
has all necessary lighting and marking as required by
law. Secure a trailer with a safety chain.
Ramp should be long enough so that the angles
between the ramp and the ground and the ramp and
the trailer or truck Do Not exceed 15°. A steeper
angle may cause mower deck components to get
caught as the unit moves from ramp to trailer or
truck. Steeper angles may also cause the unit to tip
backward. If loading on or near a slope, position
the trailer or truck so it is on the down side of the
slope and the ramp extends up the slope. This will
minimize the ramp angle. The trailer or truck should
be as level as possible.
CAUTION
This unit does not have proper turn signals,
lights, reflective markings, or a slow moving
vehicle emblem. Driving on a street or roadway
without such equipment is dangerous and
can lead to accidents causing personal injury.
Driving on a street or roadway without such
equipment may also be a violation of State laws
and the operator may be subject to traffic tickets
and/or fines.
Important: Do Not attempt to turn the unit
while on the ramp, you may lose control and
drive off the side.
Do Not drive a unit on a public street or roadway.
Avoid sudden acceleration when driving up a ramp
and sudden deceleration when backing down a ramp.
Both maneuvers can cause the unit to tip backward.
