Operating Instructions

Parking Brake

The parking brake functions by locking a pin into the hydrostatic transmission pinion gear teeth. Moving the lever FORWARD engages the parking brake; moving the lever BACKWARD releases the brake.

IMPORTANT: Stop the tractor completely before engaging the parking brake. The parking brake uses a positive mechanical lock similar to the PARK position on an automotive automatic transmission. If the tractor is moving when the brake is engaged, it will result in sudden stoppage and possible internal damage to the axle drive.

NOTE: If pressure on the parking brake pin (e.g., parked on a hill) makes it impossible to release the parking brake with the parking brake lever, move the mower gently forward or backward to release the pin.

Transmission Lockout Levers

The transmission lockout levers disengage the hydrostatic transmissons. By lifting the lever on top of the transmission and locking it into place with the lockout cam, the hydrostatic transmissions are released to permit freewheeling. By releasing the cam and lowering the lever, the transmissions are engaged for normal operation. The transmission lever in the LOCKOUT position is used to enable moving the machine without the engine running (e.g., for ser- vice). Refer to TRANSMISSION LOCKOUT in this section for operating instructions.

Lockout Lever Location

NOTE: The transmission plunger on the side of the transmission case (activated by the LOCKOUT LEVER ) must be completely released during operation of the mower, otherwise operation of the transmission will be erratic.

Hourmeter

The hourmeter, which is located on the left front of the body, displays operating time accumulated while the ignition switch is in the ON position.

Oil Pressure Warning Light

The oil pressure warning light indicates that engine oil pressure is below the safe operating range [below 3 to 5 PSI (21 to 34 kPa)]. This light will come on when the ignition is turned ON, but should go off after the engine is started. If the light fails to come on when the ignition switch is turned ON, it could indicate a burned out bulb. If the light comes on during engine operation, stop the engine immediately and correct the source of the problem before further engine op- eration.

IMPORTANT: Continued operation of the engine with an illuminated oil pressure warning light MAY cause severe engine damage (if a low oil pressure condition exists).

Circuit Breaker (5 Amp)

A5-amp, manual-reset circuit breaker is located be- low the ignition switch. The button pops up if the cir- cuit breaker trips. This circuit breaker protects the circuits to the safety switch relays, time delay mod- ule, and GHS.

Light Switch (For Optional Lights)

Operates headlights (when installed).
