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.
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 on engaged or if
you rise from the seat when the PTO is on or engaged.
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 the
other control lever.
3. Sitting on the seat, engage the parking brake, move the
PTO to off, and lock the motion control levers in
neutral. Now start the engine. While the engine is
running, release the parking brake, engage the PTO,
and rise slightly from the seat; the engine should stop.
4. Sitting on the seat, engage the parking brake, move the
PTO to off, and lock the motion control levers into
neutral. Now start the engine. While the engine is
running, center either motion control and move
(forward or reverse); the engine should stop. Repeat
for the 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 the neutral lock position. Try starting the
engine; the engine should not crank.
