STOPPING THE MACHINE. Walker DSD56, MB | Manualzz

Operating Instructions

  CAUTION

If the cutting blades strike a stationary object while mowing, stop the mower immediately, 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 REPLACING/RE PAIRING the Blade Overload Shear Bolts in

Mainte­ nance Instructions

if blades are out of time.

Also, make sure the blade retain ing nuts are torqued to 60 ft-lb (81.3 N·m).

STOPPING THE MACHINE

1. Pull the steering levers to the NEUTRAL-PARK position 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: 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 freewheeling within five (5) seconds after disengaging the clutch. If the brake system malfunctions and the blades do not stop within five (5) seconds, the brake should be repaired or replaced before operating the mower. Contact your Walker dealer.

4. 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 transaxles 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 transaxles, especially when transmission fluid is warm.

ADJUSTING CUTTING HEIGHT

  WARNING

The engine must be stopped before adjusting 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 retainer 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) increments.
