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.

absolutely necessary.
•
Always look backward and down before
backing up.

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 tractor unattended.
