Operation

The fuel gauge monitors the amount of fuel in the tank.

Drive Wheel Release Valves

Located on the right front corner of the hydrostatic pumps.

Drive wheel release valves are used to release the hydrostatic drive system to allow the machine to be moved by hand without the engine running.

With a 5/8 wrench, turn both valves one turn counterclockwise to release the drive system.

Turn clockwise to reset the drive system. Do Not overtighten. Do Not tow machine.

PTO Engagement Switch

Located on front control panel (see Figure 5).

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 engaged (see Figure 7).

Low Voltage Indicator

Located on the front control panel in the message display (see Figure 5 and Figure 7).

A low voltage condition (less than 12.3 volts) exists when the low voltage indicator light 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 Handle

Located on the RH of the front control panel.

Pull the handle rearward to raise the cutting deck. Allow the handle to move forward to lower the cutting deck to the cut height that has been set.

Pull the handle rearward and to the right to latch the cutting deck into the raised transport position (Figure 6).

Electronic Control Unit Malfunction Indicator

Kohler EFI Units Only:

The electronic control unit (ECU) continuously monitors operation of the EFI system. If a problem or fault within the system is detected, the malfunction indicator light (MIL) is illuminated. The MIL is the light located in the console panel to the left of the PTO switch. Follow the troubleshooting steps outlined in the Kohler engine operator’s manual if the MIL is illuminated.

Pre-Start

Fill fuel tank on level ground. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher.

Important: Never use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas because the fuel system could be damaged.

Do Not add oil to gasoline.

Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.
