The safety system comprises a vehicle speed sensor generating an output when vehicle speed exceeds a predetermined limit, a counter startable when the motor is actuated, and a controller connected between the speed sensor and the counter and to the apparatus for shutting down the apparatus and thereby deenergizing the motor when the vehicle-speed output exceeds the limit and when the counter has counted since the motor started beyond a predetermined limit.
