Abstract
A compact safety control apparatus and method for powered lawnmowers having a cable-actuated clutch between the motor and blade thereof is provided which includes a 'dead man' function along with an operating mechanism requiring two distinct steps for engaging the clutch and initiating rotation of the lawnmower blade. The control apparatus preferably comprises a shiftable lever and a separate, shiftable 'dead man' bail, along with an operating mechanism including a coupler positioned on the lever and movable into engagement with an end fitting on the actuating cable by means of a plate shiftable with the bail; when the coupler is initially positioned by movement of the bail, the lever is shifted to move the cable and thereby engage the clutch, whereupon the cable is releasably locked in position by interengagement of respective shoulders on the cable fitting and plate. Subsequent release of the bail releases the locking shoulders, thereby disengaging the clutch.
