Operating Instructions B23
36
CAUTION
An operator presence switch (seat switch)
will cause the engine to stop if the blade
clutch is engaged and the operator is not in
the seat. The function of this switch should
be checked by the operator raising o󰀨 the
seat and engaging the blade clutch; the en-
gine should stop. If the switch is not work-
ing, it should be repaired or replaced be-
fore operating the mower. DO NOT
disconnect the safety switches; they are
for the operator’s protection.
IMPORTANT: DO NOT engage the blade clutch
when transporting the mower across drives, side-
walks, loose materials, etc. DO NOT engage the
blade clutch with the PTO shaft disconnected
(the mower deck removed from tractor).
CAUTION
If the cutting blades strike a stationary ob-
ject while mowing, stop the mower imme-
diately, disconnect the spark plug wires, 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 Blade Overload Shear
Bolts on page 63 if blades are out of time.
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 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 excessive brake action on the
blade drive will cause premature wear of the
brake.
WARNING
A brake stops the cutter blades from free-
wheeling within ve (5) seconds after dis-
engaging the clutch. If the brake sys tem
malfunctions and the blades do not stop
within ve (5) seconds, the brake should be
repaired or replaced before further opera-
tion of the mower. Contact your Walker
dealer for service.
4. Slow the engine to idle, put throttle in IDLE
position; turn the ignition switch OFF.
WARNING
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 slip page in the hydrostatic trans-
missions, especially when transmission uid is
warm. Also, engaging the parking brake is
recommended when stopping or parking the
machine in a conned space with little toler-
ance for movement.
WARNING
If 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) Re-
lease the steering levers and simultane-
ously (2) Move the FSC to the NEUTRAL-
PARK position. When the machine is
stopped or moving slowly, engage the
parking brake.
