Danger
You could back over a child or bystander while the
mower blades or other attachment is engaged and
cause serious injury or death.
Do not mow in reverse unless absolutely
necessary.
Do not insert the KeyChoice key unless it is
absolutely necessary.
Always look backward and down before
backing up.
Use the KeyChoice switch only if you are certain
no children or other bystanders will enter the
mowing area.
Be very observant after deactivating the
interlock because the sound of the engine may
prevent you from noticing that a child or
bystander has entered the work area.
Always remove both the ignition and KeyChoice
keys and put them in a safe place out of the
reach of children or unauthorized users when
leaving the unit unattended.
1. Engage the blade control (PTO) lever.
2. Insert the KeyChoice key into the switch (Fig. 11).

Testing the Safety Interlock
System
If 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.
Test the safety system before you use the tractor 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 seat, perform the
following checks:
1. Shift the ground speed lever into Neutral (N). Set the
parking brake. Shift the blade control (PTO) lever to
Engaged. Turn the ignition key to Start; the engine
should not crank.
2. With the ground speed lever in Neutral, shift the blade
control (PTO) lever to Disengaged and release the
parking brake. Turn the ignition key to Start; the engine
should not crank.
3. With the ground speed lever in Neutral, set the parking
brake and shift the blade control (PTO) lever to
Disengaged. Start the engine. While the engine is
running, release the parking brake and rise slightly from
the seat; the engine should stop.
4. Shift the blade control (PTO) lever into the Disengage
position, the ground speed lever in Neutral, and set the
parking brake. Start the engine. While the engine is
running, shift the blade control (PTO) lever into the
Engage position, push in the clutch, and put the ground
speed lever in Reverse. The engine should stop.
5. Shift the blade control (PTO) lever into the Disengage
position, the ground speed lever in Neutral, and set the
