Using the Drive Wheel Release Valves

WARNING

Hands may become entangled in the rotating drive

components below the engine deck, which could

result in serious injury.

Stop the engine, remove the key, and allow all

moving parts to stop before accessing the drive

wheel release valves.

WARNING

The engine and hydraulic drive units can become

very hot. Touching a hot engine or hydraulic drive

units can cause severe burns.

Allow the engine and hydraulic drive units to cool

completely before accessing the drive wheel release

valves.

The drive wheel release valves are located in the back of

each hydraulic drive unit, under the seat.

Note: Make sure the release valves are in fully

horizontal position when operating the

machine or severe damage to the hydraulic

system can occur.

1. Disengage the PTO (blade control switch) and turn

the ignition key to off. Move the levers to neutral

locked position and apply the parking brake.

Remove the key.

2. Rotate the release valve levers vertically to push

the machine. This allows hydraulic oil to by-pass the

pump enabling the wheels to turn (Fig. 386).

3. Disengage parking brake before pushing.

4. Rotate the release valve levers horizontally to run

the machine (Fig. 386).
