Features and Controls

WARNING

Before operating mower, be sure to read all safety, controls and operating instructions in this Manual and on decals located on machine.

Severe personal injury or property damage could result if this instruction is not followed.

IMPORTANT: THE MOWER IS EQUIPPED WITH A BLADE-BRAKE- CLUTCH CONTROL SYSTEM WHICH IS DESIGNED TO STOP THE MOWER BLADES WITHIN THREE (3) SECONDS AFTER RELEASE OF THE OPERATOR PRESENCE CONTROL. THIS SYSTEM WILL STOP THE BLADES BUT NOT THE ENGINE. THEREFORE, YOU CAN DISEN- GAGE THE BLADE DRIVE AT ANYTIME WITHOUT HAVING TO STOP AND RESTART THE ENGINE. THIS FEATURE IS PARTICULARLY USEFUL WHEN YOU NEED TO CROSS GRAVEL DRIVES OR ROUGH TERRAIN AND YOU DO NOT WANT THE SPINNING BLADES TO STRIKE STONES OR HIDDEN OBSTACLES.

MOWER FEATURES AND CONTROLS

This section describes the various features and controls on the unit. Refer to the next section “Operation” for detailed operating instructions. Also, read the separate Engine Owner’s Manual for a detailed explanation of the proper use of the engine controls.

Operator Presence Control

The Operator Presence Control lever (A, Figure 3-1) regulates the operation of the rear wheel brake and the separate Blade Drive Control. Always engage this control before engaging the separate blade drive or wheel drive controls. Always disengage this control before starting the engine.

To engage the Operator Presence Control, press and hold the lever against the handlebar grip. Doing so releases the brake on the rear wheels, allowing the wheels to turn. The engaged position also permits the separate Blade Drive Control to lock in its engaged position (allows the mower blades to turn).

Releasing the lever (disengaged position) applies the rear wheel brake and quickly stops the wheels. Releasing

the lever will also disengage the Blade Drive Control, which will apply a brake that stops the blades within three (3) seconds.

Blade Drive Control

Use this lever (B, Figure 3-1) to en- gage drive to the mower blades.

To engage the blades, first engage the Operator Presence Control (A, Figure 3- 1). Then, push the spring-loaded Blade Drive Control lever (B) forward until it stays in the engaged position.

To stop the blades, release the Operator Presence Control (A). Doing so will disengage the Blade Drive Control

(B)and automatically apply the brake that stops the blades.

Always disengage the Blade Drive

Control before starting the engine. This helps to ensure that the blades will not start turning when the engine starts.

WARNING

The blade-brake-clutch control system should stop the mower blades within three (3) seconds after release of the Operator Presence Control.

If the blades do not stop within three

(3)seconds, put the Engine Throttle Control in the STOP position. Disconnect the spark plug wire and do not operate the mower until the blade- brake-clutch control system has been repaired.
