You are sitting on the seat.
The parking brake is engaged.
The power take off (PTO) is disengaged.
The motion control levers are in neutral locked
position.
The safety interlock system also is designed to stop the
engine when the traction controls are moved from the
locked position with the parking brake engaged or if you
rise from the seat when the PTO is on engaged.
Testing the Safety Interlock System
Test the safety interlock system before you use the
machine each time. If the safety system does not operate
as described below, have an Authorized Service Dealer
repair the safety system immediately.
1. Sitting on the seat, engage the parking brake and move
the PTO to on. Try starting the engine; the engine
should not crank.
2. Sitting on the seat, engage the parking brake and move
the PTO to off. Move either motion control lever (out
of neutral locked position). Try starting the engine; the
engine should not crank. Repeat for other control
lever.

The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place the
throttle control in the fast position for best performance.
Always operate in the full throttle position when mowing.
