Safety  
DANGER  
DANGER  
In certain conditions gasoline is extremely  
flammable and vapors are explosive.  
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.  
A fire or explosion from gasoline can burn  
you, others, and cause property damage.  
• Fill the fuel tank outdoors in an open  
area, when the engine is cold. Wipe up  
any gasoline that spills.  
• Always place gasoline containers on the  
ground away from your vehicle before  
filling.  
• Never refill the fuel tank or drain the  
machine indoors or inside an enclosed  
trailer.  
• 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.  
• Do Not fill the fuel tank completely  
full. Add gasoline to the fuel tank until  
the level is 1/4 to 1/2 inch (6–13 mm)  
below the bottom of the filler neck. This  
empty space in the tank allows gasoline  
to expand.  
• When practical, remove gas-powered  
equipment from the truck or trailer and  
refuel the equipment with its wheels on  
the ground.  
• Never smoke when handling gasoline,  
and stay away from an open flame or  
where gasoline fumes may be ignited by  
spark.  
• 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.  
• Store gasoline in an approved container  
and keep it out of the reach of children.  
• 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.  
• 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.  
WARNING  
• 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.  
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.  
• Do Not operate without entire exhaust  
system in place and in proper working  
condition.  
• Avoid prolonged breathing of vapors.  
• Keep face away from nozzle and gas  
tank/container opening.  
• Keep away from eyes and skin.  
• Never siphon by mouth.

safety switches, and shields are attached and  
functioning properly. Do Not operate unless they  
are functioning properly.  
– Before checking, cleaning or working on the  
mower.  
– After striking a foreign object or abnormal  
vibration occurs (inspect the mower for  
damage and make repairs before restarting  
and operating the mower).  
Operation  
WARNING  
– Before clearing blockages.  
Operating engine parts, especially the  
muffler, become extremely hot. Severe burns  
can occur on contact and debris, such as  
leaves, grass, brush, etc. can catch fire.  
– Whenever you leave the mower.  
• Stop engine, wait for all moving parts to stop, and  
engage parking brake:  
– Before refueling.  
• Allow engine parts, especially the muffler,  
to cool before touching.  
– Before dumping the grass catcher.  
• Remove accumulated debris from muffler  
and engine area.  
WARNING  
Hands, feet, hair, clothing, or accessories can  
become entangled in rotating parts. Contact  
with the rotating parts can cause traumatic  
amputation or severe lacerations.  
• Install and maintain in working order a  
spark arrester before using equipment  
on forest-covered, grass-covered, or  
brush-covered unimproved land.  
• Do Not operate the machine without  
guards, shields, and safety devices in  
place and working properly.

which is an odorless deadly poison that can  
kill you.  
• Keep hands, feet, hair, jewelry, or clothing  
away from rotating parts.  
NEVER carry passengers. DO NOT operate  
the mower when people, especially children, or  
pets are in the area.  
Do Not run engine indoors or in a small  
confined area where dangerous carbon  
monoxide fumes can collect.  
• Be alert, slow down and use caution when making  
turns. Look behind and to the side before  
changing directions.  
• Operate only in daylight or good artificial light,  
keeping away from holes and hidden hazards.  
• Stop the blades, slow down, and use caution when  
crossing surfaces other than grass and when  
transporting the mower to and from the area to  
be mowed.  
• Be sure all drives are in neutral and parking brake  
is engaged before starting engine. Use seat belts  
with the roll bar in the raised and locked position.

Safety  
• Be aware of the mower discharge path and direct  
discharge away from others.  
• Do Not operate the mower under the influence  
of alcohol or drugs.  
• Use extreme care when loading or unloading the  
machine into a trailer or truck.  
• Use care when approaching blind corners, shrubs,  
trees, or other objects that may obscure vision.  
Slope Operation  
Figure 3  
Use Extreme caution when mowing and/or turning  
on slopes as loss of traction and/or tip-over could  
occur. The operator is responsible for safe operation  
on slopes.  
1. Safe Zone-Use the mower here on slopes less than 15  
degrees  
2. Danger Zone-Use a walk behind mower and/or hand  
trimmer on slopes greater than 15 degrees, near  
drop-offs and water.  
3. Water  
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.  
• Remove or mark obstacles such as rocks, tree  
limbs, etc. from the mowing area. Tall grass can  
hide obstacles.  
• Watch for ditches, holes, rocks, dips and rises that  
change the operating angle, as rough terrain could  
overturn the machine.  
• Do Not mow slopes when grass is wet.  
• Do Not mow near drop-offs or near water.  
• Avoid sudden starts when mowing uphill because  
the mower may tip backwards.  
• Do Not mow slopes greater than 15  
degrees.  
• 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.  
• Reduce speed and use extreme caution  
on slopes.  
• Avoid sudden turns or rapid speed  
changes.  
• Always avoid sudden starting or stopping on a  
slope. If tires lose traction, disengage the blades  
and proceed slowly off the slope.  
• Keep the roll bar in the raised and locked  
position and use seat belt.  
• Follow the manufacturer’s recommendations for  
wheel weights or counter weights to improve  
stability.  
• See inside the back cover to determine the  
approximate slope angle of the area to be mowed.  
• Use extreme care with grass catchers or  
attachments. These can change the stability of the  
machine and cause loss of control.  
• Use a walk behind mower and/or a hand trimmer  
near drop-offs, ditches, steep banks or water.

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.  
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.  
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.  
Do Not drive a unit on a public street or  
roadway.  
Important: Do Not attempt to turn the unit  
while on the ramp, you may lose control and  
drive off the side.  
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.  
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.  
• 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.  
• Avoid sudden deceleration while backing  
unit down 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

idler counterclockwise to remove the belt.  
Note: Loosen or tighten the single point  
adjustment bolt enough to move the height-of-cut  
plate mounting bolts at least 1/3 the length of  
the available travel in their slots. This will regain  
some up and down adjustment on each of the  
four deck links.  
6. Remove and retain the hardware on both sides of  
the deck as shown in Figure 29.
