Important If the engine does not start after 15 seconds
of continuous cranking, turn the ignition key to Off and let
the starter motor cool for 2 minutes; refer to
Troubleshooting on page 38.

Stopping the Engine
1. Move the throttle control lever to Slow (Fig. 11).
Important To prevent backfiring and damage to the
engine, do not shift the throttle control lever to the Choke
or Fast positions to stop the engine.
2. Turn the ignition key to Off (Fig. 11).
Note: If the engine has been working hard or is hot, let it
idle for a minute before turning the ignition key to Off.
This allows the engine to cool the engine before you stop it.
You may stop the engine in an emergency by turning the
ignition key to Off.
Using the Safety Interlock
System
If the safety interlock switches are disconnected or
damaged, the tractor 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 tractor.
• Replace switches every 2 years regardless of
whether they are operating properly or not.
Caution
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 brake pedal is depressed.
• The blade control (PTO) knob is in the Disengaged
position.
• The traction control pedal is in Neutral.
The safety interlock system stops the engine if you rise
from the seat and the traction control pedal is not in the
Neutral position, the parking brake is not set, or the blade
control (PTO) knob is in the Engaged position.
The safety interlock system is designed to stop the mower
if:
• You shift into Reverse with the blades (PTO) engaged.
• You remove the bag or dump the grass.
