The Safety Interlock System
Understanding the Safety Interlock
System
Caution
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
Do not tamper with the interlock switches.
Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
The safety interlock system is designed to prevent the
engine from starting if:
The throttle lever is all the way back, to stop.
The blade control lever (PTO) is engaged.
The safety interlock system is also designed to stop the
engine if you released the bail with the PTO engaged or
move the throttle all the way back, to stop.

the safety system immediately.

throttle forward. Start the engine. With the engine
running squeeze the bail against upper control bar and
push the mower blade control lever forward. The
mower blades begin rotating.
