1. The operator presence & safety interlock system prevents the engine from starting unless the parking
brake is on, and the mowing device is switched off. The system stops the engine if the operator leaves the
seat with the parking brake disengaged. If the operator leaves the seat with the mowing device engaged
and the parking brake on the mowing device will stop.
