Safety Instructions
14. The maximum recommended slope operat-
ing angle is 15 degrees or 27% grade.
When operating the machine on a slope, re-
duce speed and use caution to start, stop, and
maneuver. To prevent tipping or loss of control
of the machine, avoid sharp turns or sudden
changes in direction. Do not operate the
machine on a slope greater than 15 de-
grees.
15. Never adjust cutting height with the engine
running. Before adjusting cutting height or
servicing, disengage the blade clutch (PTO),
engage parking brake, stop the engine, and
remove the ignition key. Wait for all movement
to stop before getting off the seat.
NOTE: A blade/blower brake should normally
stop drive line rotation within five (5) seconds
of disengaging the PTO clutch.
16. For side discharge mower decks, do not op-
erate with the grass deflector shield re-
moved. Keep the deflector in the lowest
possible position.
17. When using the tilt-up deck, observe the
following:
a. Do not move tractor with deck in tilt-up
position.
b. Never tilt body forward with deck in tilt-up
position.
18. For GHS equipped models, do not operate
the machine with the grass catcher in the
DUMP position or with the back door
OPEN. Dangerous projectiles may be thrown
out of the discharge chute or the back of the
grass catcher.
19. For GHS equipped models, use care when
closing the grass catcher door. Keep fin-
gers and hands away from the hinge and
pinch points when the door is being closed.
Also, keep fingers and hands clear of the door
frame. The door may slam shut with consider-
able force.
14
CAUTION
Use leg muscles and firm footing when lift-
ing the catcher to dump; avoid bending at
the waist and using back muscles in order
to prevent back injury.
20. In case of a clogged or plugged mower
deck or GHS catching system:
a. Disengage the blade clutch (PTO), engage
the parking brake, and turn the engine off
before leaving the seat.
b. LOOK to make sure blade drive shaft and
blower drive pulley movement has stopped
before trying to unclog the system.
c. Disconnect the electrical plug on the fuel
shut-off solenoid.
d. Never place hands under the deck or in
the GHS blower - use a stick or similar tool
to remove clogged material.
21. If the cutting blades strike a solid object or the
machine begins to vibrate abnormally, imme-
diately disengage the blade clutch (PTO),
engage the parking brake, stop the engine,
and wait for all moving parts to stop. To
prevent accidental starting, disconnect the
electrical plug on the fuel shut-off solenoid.
Thoroughly inspect the mower and repair any
damage before restarting the engine and
operating the mower. Make sure cutter blades
are in good condition and blade nuts are
torqued to 60 lb·ft (81 N·m) for gear-driven
decks, and blade bolts torqued to 70 lb·ft (95
N·m) for belt-driven decks.
22. Do not touch the engine or muffler while
the engine is running or immediately after
stop ping the engine. These areas may be hot
enough to cause serious burns.
23. Do not stop or park in or near dry grasses
or bushes when operating the mower. The
heat from the engine or muffler could ignite the
dry material.
24. Never remove the radiator pressure cap
when the engine is hot (hot water may spray
and cause burns).
