SAFETY INTERLOCK SYSTEM
4.2 
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.
