Operation
The Safety Interlock System
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
You are sitting on the seat
The parking brake is "ENGAGED"
The power take off (PTO) is disengaged "OFF"
The motion control levers are in neutral locked
position
The safety interlock system also is designed to stop
the engine when the traction controls are moved from
the locked position with the parking brake
"ENGAGED" or if you rise from the seat when the
PTO is "ON" engaged.
