Checking the Safety System

The ride-on mower is equipped with a safety system that
prevents starting or driving in the following conditions.
It must only be possible to start the engine when the following
conditions are met:
Blades shut off, blade drive not engaged.
Parking brake applied.
The driver does not need to be seated in the driver's seat.
Check daily to ensure that the safety system works by
attempting to start the engine when one of the conditions is
not met. Change the conditions and try again.
Check that the engine stops if you temporarily move out of
the driver's seat while the mower blades are engaged.
