ABSTRACT:
A transaxle is provided, especially for small riding vehicles, such as lawn mowers. The transaxle is exceptionally shallow, with the gear shift lever entering the housing on about the same level as the rear axles. The transaxle has six forward speeds in a compact housing by virtue of a unique gear train arrangement in which shafts serve multiple functions. A driven bevel gear in the transaxle housing is also backed-up by a structurally-integral rib or flange in the housing. A unique bearing design provides effective lubrication for the output shafts or axles of the transaxle. A compact differential of the transaxle also rotates within a cavity without any axle.
