Operating Instructions

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 op erator raising off 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 immedi-

ately, disconnect the spark plug wires, lift

the deck, and inspect the deck and blades

thoroughly for damage. Also, make sure

the blade retaining bolts are torqued to 70

lb·ft (95 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

throttle) since the brake action on the blade

drive will cause premature wear of the brake

band.

WARNING

A brake stops the cutter blades from free-

wheeling within five (5) seconds after dis-

engaging the clutch. If the brake system

malfunctions and the blades do not stop

within five (5) seconds, the brake should be

adjusted or repaired before further opera-

tion of the mower. Contact your Walker

dealer, or refer to

Clutch Disengagement/

Brake Action on page 75.

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 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.
