Briggs & Stratton MB (18 HP) owner manual Stopping the Machine, Cutting Height Adjustment

Operating Instructions

STOPPING THE MACHINE

1.Slow the engine to idle; put the throttle in the IDLE position.

2.Pull the steering levers to the NEUTRAL-PARKposition and then move the FSC lever backward to the NEUTRAL-PARKposition.

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 Engine/PTO Belt and electric clutch/brake.

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 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.

IMPORTANT: The 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 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 retainer hitch pins in a series of seven vertical holes on the deck support pins. Lift handles have been provided on each end of the deck to assist in raising the deck while positioning the hitch pins. Cut- ting heights range from 1 in. (25 mm) [top holes] to 4 in. (102 mm) [bottom holes] in 1/2 in. (13 mm) increments.
