ABSTRACT:
A lawn mower is powered by two vertical shaft engines mounted on the chassis and equispaced about the longitudinal axis of the chassis. A vertical drive shaft is rotatably mounted on the longitudinal axis of the chassis. The outputs of both vertical shaft engines are transmitted through belts and pulleys to the vertical drive shaft, which is rotated by the combined outputs of both vertical shaft engines. Other pulleys are secured to the vertical drive shaft and connected through belting to pulleys which rotate grass-cutting blades and to pulleys which operate motors turning the driving wheels to propel the lawn mower.
