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 11).
3. Turn the KeyChoice key.
Note: The operating-in-reverse light on the front
console (Figure 12) turns on, indicating that the
interlock is disabled.

position, put the traction control pedal in the Neutral
