SAFETY INTERLOCK SYSTEM4.2
The mower is equipped with a safety interlock system that
prevents the engine from starting unless the deck drive is
disengaged, the parking brake is engaged, 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.
