Mower Cutting Height Switch

To increase the mower cutting height (raise the mower deck), press the top of the yellow cutting height switch. To decrease mower cutting height (lower the mower deck), press the bottom of the switch. Mower cutting height range is approximately 3-3/4” to 1-1/2”. The cutting height gauge indicates the position of the mower deck. The cutting height gauge is located on the front of the rider, just behind the driver’s left leg.

Ignition Switch

The ignition switch starts and stops the engine; it has three positions:

OFF Stops the engine and shuts off the electrical system.

RUN Allows the engine to run and powers the electrical system.

START Cranks the engine for starting.

NOTE: Never leave the ignition switch in the RUN position with the engine stopped. This drains the battery.

Hour Meter

The hour meter measures the number of hours the key has been in the RUN position.

NOTE: The hour meter will register the passage of time when the key is in the RUN position, even if the engine is not running.

Mower Blade Switch

The yellow mower blade switch turns the mower blades on and off. To turn the mower blades ON, pull the switch up. To turn the mower blades OFF, push the switch down. Always set the engine speed control to FAST before turning the mower blades ON, and while mowing.

Transmission Release Levers

The transmission release levers deactivate the transmissions so that the unit can be pushed by hand. See PUSHING THE UNIT BY HAND for operational information.

Fuel Tank

To remove the fuel tank cap, turn it counterclockwise.

GENERAL OPERATING SAFETY

Before first time operation:

Be sure to read all information in the Safety and Operation sections before attempting to operate this rider and mower.

WARNING

If you do not understand how a specific control functions, or have not yet thoroughly read the CONTROL FUNCTIONS section, do so now.
