The Safety Interlock System

If safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock
switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
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 off.
• The motion control levers are in the 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 switch is on.

Testing the Safety Interlock System
Test the safety interlock system before you use
the machine each time. If the safety system
does not operate as described below, have an
Authorized Service Dealer repair the safety system
immediately.
1. Sitting on the seat, engage the parking brake
and move the PTO to on. Try starting the
engine; the engine should not crank.
2. Sitting on the seat, engage the parking brake
and move the PTO to off. Move either motion
control lever (out of neutral locked position).
Try starting the engine; the engine should not
crank. Repeat for other control lever.
3. Sitting on the seat, engage the parking brake,
move the PTO switch to off and move the
motion control levers to neutral lock position.
Now start the engine. While the engine is
running, release the parking brake, move the
PTO to on and rise slightly from the seat; the
engine should stop.
4. Sitting on the seat, engage the parking brake,
move the PTO switch to off and move the
motion control levers to neutral lock position.
Now start the engine. While the engine is
running, center either motion control and
move (forward or reverse); the engine should
stop. Repeat for other motion control.
5. Sitting on the seat, disengage the parking brake,
move the PTO switch to off and move the
motion control levers to neutral lock position.
Try starting the engine; the engine should not
crank.
Driving Forward or
Backward
The throttle control regulates the engine speed as
measured in RPM (revolutions per minute). Place
the throttle control in the fast position for best
performance. Always operate in the full throttle
position when mowing.
