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 increased wear of the brake band.
WARNING
A brake stops the cutter blades (and
blower on GHS equipped models) from
freewheeling within ve (5) seconds after
disengaging the clutch. If the brake sys-
tem malfunctions and the blades do not
stop within ve (5) seconds, the brake
should be adjusted or repaired before op-
erating the mower. Contact your Walker
dealer.
4. Turn the ignition switch OFF. When stopping
the engine, do not reduce the throttle below 1/2
speed. Since the engine is equipped with a
shutdown solenoid, stopping at low idle may
cause engine run-on or backring.
WARNING
Remove the key from the ignition switch
when leaving the mower unattended. This
will prevent children and inexperienced
operators from starting the engine.
5. Engage the parking brake. Also, engaging the
parking brake is recommended when stopping
or parking the machine in a conned space with
little tolerance for movement.
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 uid is warm.
WARNING
In case the transmission drive belt breaks
during operation, and if the machine is on
a slope, the machine will freewheel down
the slope. To maintain control, immediately
(1) Release the steering levers and
simultaneously (2) Move the FSC to the
NEUTRAL-PARK position. When the
machine is stopped or moving slowly,
engage the parking brake.
NOTE: The emergency stop procedure is ex-
actly the same procedure as used to normally
stop and park the machine.
