ABSTRACT:
A compact transmission designed particularly for a self-propelled, walking lawn mower is provided. The transmission is mounted on the deck of the mower behind the engine and is connected to a power take-off shaft of it. The transmission has two forward speeds and is shifted by a short finger-operated shift lever extending rearwardly. The transmission is compact, light in weight, and low in cost. These are achieved, in part, by the gears being arranged to occupy a minimum space and a one-piece shifter fork and guide plate being made of plastic material and assembled through an opening in the top of the transmission housing. The transmission housing also can use either a horizontal or a vertical input shaft with minimum change in design.
