diately, disconnect the spark plug wires, lift
the deck, and inspect the deck and blades
thoroughly for damage. Make sure that the
blade timing has not been dis turbed (the
blades should be at 90 degrees to each
other). Refer to REPLACING/RE PAIRING

STOPPING THE MACHINE
1. Pull the steering levers to the
NEUTRAL-PARK
posi tion and then move the FSC lever backward
to the
NEUTRAL-PARK
position.
2. Slow the engine to a fast idle; put the throttle in
the 1/2 throttle position.
3. Disengage the blade clutch.
IMPORTANT:
DO NOT
disengage the blade
clutch with high engine speed (above 1/2 throt-
tle) since the brake action on the blade drive will
cause premature wear of the brake band.
WARNING
A brake stops the cutter blades (and
blower on GHS equipped models) from
freewheeling within five (5) seconds after
disengaging the clutch. If the brake sys-
tem malfunctions and the blades do not
stop within five (5) seconds, the brake
should be adjusted or repaired before op-
erating the mower. Contact your Walker
dealer, or refer to ADJUSTMENTS of
Clutch Disengagement/Brake Action in
Maintenance Instructions.
