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: The blade/PTO brake should normally
stop drive line rotation within ve (5) seconds of
disengaging the PTO clutch.
15. 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.
16. When using the tilt-up deck, observe the fol-
lowing recommendations:
a. Do not move tractor with deck in tilt-up
position.
b. Never tilt body forward with deck in tilt-up
position.
17. In case of a clogged or plugged mower deck:
a. Disengage the blade clutch (PTO) and turn
the engine off before leaving the seat.
b. LOOK to make sure blade drive shaft
movement has stopped before trying to un-
clog the system.
c. Disconnect the spark plug wires.
d. Never place hands under the deck - use a
stick or similar tool to remove clogged ma-
terial.
18. 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 lb·ft (81 N·m) for gear driven decks, and
blade bolts torqued to 70 lb·ft (90 N·m) for belt
driven decks.
19. 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.
20. When leaving the machine unattended, disen-
gage the blade clutch (PTO), stop the en-
gine, and remove the key.
