Abstract: A riding mower has a frame supported by a plurality of wheels including a pair of front drive wheels covered by front fenders. A plurality of cutting units are arranged in advance of the frame. The operator sits on a seat atop the frame at the front of the frame. The operator mounts and dismounts the seat from behind the front fenders and the front wheel and not from the front, access to the seat from the front being prevented by the placement of the cutting units. A pivotal armrest along one side of the seat normally blocks access to the seat from that side. However, the armrest can be pivoted to a raised position in which it clears the seat to allow the operator to reach the seat from that side of the seat.

Abstract: A self-propelled power lawn wherein an operator can operate the mower while standing on a foot platform, or alternatively when sitting down on a selectively deployable seat. The operator may operate the mower from a standing position regardless of whether the seat is deployed or not. A shorter control arms extending between a tractor frame structure and a cutter deck assembly having a mower deck lift system raising and lowering the cutter deck assembly together with the engine deck assembly. A portion at the rear of the cutter deck assembly cut out and covered with a plate in order to form a depression over a rear edge of the cutter deck. This depression enables the clutch located over top of the depression (and thus the engine) to be located at a lower elevation so as to lower the overall center of gravity of the mower.

Abstract: A sulky for a self propelled lawn mower, the sulky being interconnected by a pivot frame and a horizontal pivot to the mower frame, and a parallelogram link structure to mount the seat to the sulky for automatic adjustment of the seat to lawn mower distance as the mower moves over uneven ground.

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.
