Drive Wheel Release Valves

WARNING

Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury or death.

Stop engine, remove key, allow all the 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.

Located on the back of the unitized hydraulic drive units, below the engine deck.

During normal operating conditions, the drive wheel release valves are positioned horizontally. If the machine has to be pushed by hand, the valves must be in the “released” position (see Figure 10).

2.Handle in “operating” position

To release the drive system (see item 1 in Figure 10), rotate the handle 1/4 turn to the vertical position until it hits against the stop.

To reset the drive system (see item 2 in Figure 10), rotate the handle 1/4 turn to the horizontal position until it hits against the stop.

Note: The handle must be horizontal and against the stop for operation.

Do Not tow machine.

PTO Engagement Switch

Located on right console (see Figure 6).

Switch must be pulled out (up) to engage the blades. Switch is pushed in to disengage the blades.

The LCD indicator will appear when the PTO switch is disengaged (see Figure 9).

Low Voltage Indicator

Located on the right console in the message display (see Figure 6 and Figure 9).

A low voltage condition (less than 12.3 volts) exists when the LCD indicator appears on the message display while the engine is running.

If the ignition key is turned to the “ON” position for a few seconds before cranking the engine, the battery voltage will display in the area where the hours are normally displayed.

Note: The indicator normally appears when the engine is off and the key switch is turned to the “ON” position.

Deck Lift Pedal

Located at the right front corner of the floor pan.

Push the pedal forward with your foot to raise the cutting deck. Allow the pedal to move rearward to lower the cutting deck to the cut height that has been set.

Transport Lock

Located on the height of cut adjustment plates to the right of the parking brake.

Position in the transport latching position to automatically latch the cutting deck when raised to the transport position (see item 1 in Figure 11).

In the non-latching position, the deck will automatically return to the cutting height when the pedal is lowered (see item 3 in Figure 11).
