Understanding the Safety Interlock System
The safety interlock system is designed to prevent
the mower blades from rotating; unless at least one
of the OPC levers is engaged and the blade control
switch (PTO) is pulled on.
The safety interlock system is designed to stop the
mower blades if you release both OPC levers.
Note: Park brake must be disengaged before the
speed control lever is moved out of neutral or engine
will kill.

and push the speed control lever forward.
The engine should initiate shutdown after
momentary pause.
4. Start the engine and release the parking brake.
