Safety Instructions
14. The maximum recommended slope operat-
ing angle is 15 degrees or 26% grade. When
operating the machine on a slope, reduce speed
and use caution to start, stop, and maneuver.
To prevent tipping or loss of control of the ma-
chine, avoid sharp turns or sudden changes in
direction. Do not operate the machine on a
slope greater than 15 degrees.
15. 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 ve (5) seconds of
disengaging the PTO clutch.
16. For side discharge mower decks, do not oper-
ate with the grass deector shield removed.
Keep the deector in the lowest possible posi-
tion.
17. When using the tilt-up deck, observe the fol-
lowing:
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. Dan-
gerous projectiles may be thrown out of the dis-
charge chute or the back of the grass catcher.
19. 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 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, immedi-
ately disengage the blade clutch (PTO), stop
the engine, and wait for all moving parts to
stop. To prevent accidental starting, discon-
nect the spark plug wires. Thoroughly inspect
the mower and repair any damage before re-
starting 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.
21. Do not touch the engine or mufer 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.
