Operating Instructions

WARNING

In case 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)Release the steering levers and simultaneously (2) Move the FSC to the NEUTRAL-PARK position. When the machine is stopped or moving slowly, engage the parking brake.

NOTE: The emergency stop procedure is ex- actly the same procedure as used to normally stop and park the machine.

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 move­ment to stop before getting off the seat.

Cutting height is adjusted by positioning the four (4) 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. 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.

TRANSMISSION LOCKOUT

IMPORTANT: DO NOT TOW this mower with the transmission lockout engaged. Towing can produce excessive internal pressure and damage the trans­ mission.

To move the mower with the engine NOT running (dead battery, maintenance, etc.), the hydrostatic transmissions are unlocked (released).

1.Raise the body.

2.Lift the transmission lockout lever on both the RH and LH transmissions and secure into place with the locking cam.

3.The mower will “freewheel” with the levers in the LOCKOUT position. The levers must be in the highest position to completely unlock the trans­ missions.
