Safety Instructions
13
14. Never adjust cutting height with the engine
running. Before adjusting cutting height or
servicing, disengage the blade clutch (PTO),
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.
15. For side discharge mower decks, do not oper-
ate with the grass deflector chute removed.
Keep the deflector in the lowest possible posi-
tion.
16. For tractors equipped with tilt-up deck, observe
the following recommendations:
a. Do not move tractor with deck in tilt-up
position.
b. Never tilt body forward with deck in tilt-up
position.
17. For GHS equipped models, do not operate the
machine with the grass catcher in the DUMP
position or with the back door OPEN. Dan-
gerous projectiles may be thrown out of the dis-
charge chute or the back of the grass catcher.
18. For GHS equipped models, use care when
closing the grass catcher door. Keep fingers
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 considerable
force.
19. In case of a clogged or plugged mower deck
or GHS catching system:
a. Disengage the blade clutch (PTO) 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 spark plug wires.
d. Never place hands under the deck or in the
GHS blower - use a stick or similar tool to
remove clogged material.
20. If the cutting blades strike a solid object or the
machine begins to vibrate abnormally,
immediately disengage the blade clutch
(PTO), stop the engine, and wait for all
moving parts to stop. To prevent accidental
starting, disconnect the spark plug wires.
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 ft-lb (81.3 N · m).
21. 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.
22. When leaving the machine unattended, disen-
gage the blade clutch (PTO), stop the en-
gine, and remove the key.
CAUTION
Use leg muscles and firm footing when lift-
ing the catcher to dump; avoid bending at
the waist and using back muscles to avoid
back injury.
