4.2 SAFETY INTERLOCK SYSTEM
The mower is equipped with a safety interlock system that
prevents the engine from starting unless the deck drive is
disengaged, the steering control levers are in the neutral
position and the operator is in the seat. The interlock
system shuts off the engine if the operator leaves the seat
with the steering control levers not in the neutral position
and/or the cutter blades engaged and the parking brake
not engaged.
WARNING
Never operate the mower with the interlock
system disconnected or malfunctioning. Do not
disengage or bypass any switch; injury to yourself
and others or property damage could result.
4.3 TESTING THE SAFETY INTERLOCK
SYSTEM
1. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, and engage the PTO switch
to the ON (up) position. Try to start the engine; the
engine should not start
2. Sit in the seat in the operating position, engage the
parking brake, move the PTO switch to the OFF
(down) position, move either of the steering control
handles out of the neutral lock position. Try to start
the engine; the engine should not start. Repeat for
the other steering control lever.
-NOTE-

engaged or disengaged. For all test procedures
listed below, the engine should be started with the
parking brake engaged unless specified otherwise.
