Operating Instructions
A brake stops the cutter blades (and blower
on GHS equipped models) from freewheel-
ing within five (5) seconds after disengag-
ing the clutch. If the brake sys tem malfunc-
tions and the blades do not stop within five
(5) seconds, the brake should be repaired
or replaced before further operation of the
mower. Contact your Walker dealer for ser-
vice.
Slow the engine to idle, put throttle in IDLE
4.
position; and turn the ignition switch OFF.
Remove the key from the ignition switch
when leaving the mower unattended. This
will prevent children and inexperienced op-
erators from starting the engine.
5.
Engage the parking brake by moving the lever
forward.
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 slippage in the hydrostatic trans-
missions, especially when transmission fluid is
warm. Also, engaging the parking brake is
recommended when stopping or parking the
machine in a confined space with little toler-
ance for movement.
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, immediate-
ly (1) Release the steering levers and si-
multaneously (2) Move the FSC to the NEU-
TRAL-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.
ADJUSTING CUTTING HEIGHT
WARNING
The engine must be stopped before adjust-
ing cutting height. Disengage the blade
clutch (PTO), engage the parking brake,
stop the engine, and remove the ignition
key. Wait for all move ment to stop before
getting off the seat.
Cutting height is adjusted by positioning the four
(4) re tainer hitch pins in a series of six vertical
holes on the deck support pins. Lift handles have
been pro vided on each end of the deck to assist in
raising the deck while positioning the hitch pins.
Cutting heights range from 1.5 in. (38 mm) [top
holes] to 4 in. (102 mm) [bottom holes] in 1/2 in.
(13 mm) incre ments.

TRANSAXLE LOCKOUT
IMPORTANT: DO NOT TOW this mower faster
than 2 mph (3.2 km/h) with the transaxle lockout
engaged. Towing can produce excessive internal
pressure and damage the transaxle(s).
To move the mower with the engine NOT running
(dead battery, maintenance, etc.), the transaxles
need to be unlocked (released).
