Understanding the
Safety-Interlock System
The safety-interlock system is designed to prevent the
engine from starting unless:
•
The blade-control switch (PTO) is disengaged.
•
The motion-control levers are in the P
ARK
position.
The safety-interlock system also is designed to shut
off the engine whenever the control levers are out of
the P
ARK
position and you rise from the seat.
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.

engine; the engine should not crank.

Sit on the seat and move the blade-control switch
to the O

lever to the center, unlocked position. Try
starting the engine; the engine should not crank.
Repeat with the other motion-control lever.

Sit on the seat, move the blade-control switch
to the O
