Stopping The Machine; Adjusting Cutting Height - Walker MS Operator's Manual

Operating Instructions
If the cutting blades strike a stationary ob-
ject while mowing, stop the mower imme-
diately, disconnect the spark plug wire, 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
the Blade Overload Shear Bolts in
nance Instructions
Also, make sure the blade retain ing nuts
are torqued to 60 lb·ft (81 N·m).

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 idle; put the throttle in the
IDLE position.
3. Disengage the blade clutch.
IMPORTANT:
clutch with high engine speed (above 1/2 throt-
tle) since the brake action on the blade drive will
cause increased wear of the PTO Drive Belt.
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.
Turn the ignition switch OFF.

CAUTION

DO NOT disengage the blade
WARNING
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.

ADJUSTING CUTTING HEIGHT

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.
Cutting height is adjusted by positioning the four (4)
re tainer hitch pins in a series of seven 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 in. (25 mm) [top holes] to
4 in. (102 mm) [bottom holes] in 1/2 in. (13 mm)
incre ments.
