Danger
You could back over a child or bystander while the
mower blade 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 PTO.
2. Insert the KeyChoice key into the switch (Fig. 9).

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. Move the PTO lever to Engage. Sit on the seat and
rotate the ignition key to Start; the engine should not
crank. If it does, the interlock system is malfunctioning,
and it must be repaired by an Authorized Service
Dealer. If the engine does not crank, proceed to step 2.
2. Move the PTO lever to Disengage. Sit on the seat, and
release the parking brake. Rotate the ignition key to
Start; the engine should not crank. If it does, the
interlock system is malfunctioning and must be repaired
by an Authorized Service Dealer. If the engine does not
crank, proceed to step 3.
3. Sit on the seat, put the PTO lever in the Disengage
position, and the traction control pedal in neutral.
Ensure that the parking brake is engaged. Rotate the
ignition key to Start; the engine should start and
continue to run. Then engage the PTO lever and
carefully rise from the seat; the engine should stop. If
the engine does not stop running, shut the engine off
and have the interlock system repaired by an
Authorized Service Dealer. If the engine shuts off when
you rise from the seat, the interlock system is
functioning correctly and the tractor can be operated
safely.
