STOPPING THE MACHINE
1. Slow the engine to a fast idle; put the throttle in
the 1/2 throttle position.
2. Pull the steering levers to the NEUTRAL
position and then move the FSC lever
backward to the NEUTRAL-PARK 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.
4. Slow the engine to idle, put throttle in IDLE
position; and turn the ignition switch OFF.
5. Engage the parking brake.
IMPORTANT: The hydrostatic transmissions
lock to prevent the mower from rolling freely with
the engine stopped. However, if the mower is
parked on a slope, it is necessary to ENGAGE
the parking BRAKE to prevent the mower from
creeping. This is due to a small amount of slip-
page in the hydrostatic transmissions, especially
when transmission fluid is warm.
ADJUSTING CUTTING HEIGHT

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.
WARNING
Remove the key from the ignition switch
when leaving the mower unattended. This
will prevent children and inexperienced
operators from starting the engine.
WARNING
The engine must be stopped before ad-
justing cutting height. Disengage the
blade clutch (PTO), stop the engine, and
remove the ignition key. Wait for all move-
ment to stop before getting off the seat.
