idle for a minute before turning the ignition key off. This
helps cool the engine before it is stopped. In an
emergency, the engine may be stopped by turning the
ignition key to off immediately.

The Safety Interlock System

Caution
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:
• The parking brake is set.
• The power take off (PTO) is disengaged or off.
• The motion control levers are in neutral position.
The safety interlock system also is designed to stop the
engine when:
• The motion control levers are moved out of neutral
with the parking brake is set.
• You rise from the seat when the power take off (PTO)
is on or the motion control levers are not in neutral
• The motion control levers are moved out of neutral or
PTO is engaged with the hopper tilted up
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.
While sitting in the mower seat:
1. Set the parking brake and move power take off (PTO)
to on. Try starting the engine; the engine should not
crank.
2. Set the parking brake and move power take off (PTO)
to off. Move one then the other motion control lever
forward or reverse. Try starting the engine; the engine
should not crank.
3. Set the parking brake, move power take off (PTO) to
off and hold the motion control levers in neutral. Now
start the engine. While the engine is running engage
the power take off (PTO) and rise slightly from the
seat; the engine should stop.
