● In case of a clogged or plugged mower
deck:
1. Disengage the blade clutch (PTO), engage
the parking brake, and turn the engine off
and remove the ignition key before leaving
the seat.
2. Listen to make sure all moving parts have
stopped before attempting to lift and visu-
ally inspect the deck.
3. Never place hands under the deck. Use
a stick or similar tool to remove clogged
material.
● If the cutting blades strike a solid object
or the machine begins to vibrate abnor-
mally, 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

mower. Make sure cutter blades are in good
condition and blade bolts are torqued to 70
lb·ft (95 N·m).
