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 it is absolutely
necessary.
• Do not insert the KeyChoice key unless it is
absolutely necessary.
• Always look backward and down before
backing up the machine.
• Use the KeyChoice switch only if you are
certain that 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
you leave the machine unattended.
1. Engage the blades (PTO).
2. Insert the KeyChoice key into the switch (Figure 13).

Disengage position, put the traction control pedal
