Abstract
A motor-powered lawn mower is described which includes provisions for converting same from a walk-behind mower to a stand-up riding mower. A driven shaft associated with the rear wheels is journaled for rotation at the lower ends of a pair of pivot arms which are hinged to opposed sides of the mower's frame. Also coupled to the pivot arms is a riding platform. When the rear wheel assembly is swung forward relative to the frame, the riding platform is tucked beneath the frame so as not to obstruct the feet of the operator walking behind the mower and guiding its path of travel. By swinging the rear wheel assembly to extend rearward of the frame, the riding platform becomes deployed in a horizontal position so that the operator may stand upon it as he manipulates the controls to steer the vehicle.
