Operating Instructions
38
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.
4. Slow the engine to idle, put throttle in
IDLE
posi-
tion; and turn the ignition switch
OFF.
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 confined 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 fluid is warm.
WARNING
In case either of the transmission drive
belts break 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 exactly
the same procedure as used to normally stop and
park the machine.
