ABSTRACT:
A self-propelled lawnmower employs a hydrostatic transmission and differential to power rear drive wheels which are situated behind a forward mowing deck. The hydrostatic drive has infinitely variable adjustment of speed from reverse, through neutral, to a maximum forward speed. There are independently actuated disc brakes for the drive wheels, with right and left brake levers situated adjacent the operator hand grips. A vertical shaft engine is situated with its center of gravity behind the drive wheel shaft to balance the weight of the mowing deck. The operator can control the speed and direction of the mower without removing his hands from the hand grips. By selecting actuation of the disc brakes, the machine can be effortlessly turned without a reduction in speed. The engine output shaft has pulleys connected by drive belts to the blades and to the hydrostatic drive.
