CONTROLS

Operator Presence Switches

Located on the handle, the Operator Presence System levers serve as an additional safety feature. An electrical interlock safety system is activated by depressing either one or both of the Operator Presence Levers at the handle grips.

Releasing both Operators Presence Levers while mowing or transporting will break the electrical circuit and cause the engine and mower to stop. The mower will not stop immediately after releasing the OP levers and some travel occurs.

When either the blades or the speed control are engaged, one or both levers must be pressed for the engine to remain running.

Ground Speed Control

Ground speed is adjusted with the center lever on the control panel. Ease the lever out of the start position and upwards to the desired speed.

Choke Control

The choke control is used for cold starts to provide the engine with a richer fuel mixture.

To engage the control, pull the choke out to its extent. Do not use the choke when starting a warm engine.
