Abstract
An implement having an engine and a transaxle which may be rigidly and directly attached to one another in a vertically stacked orientation to form an engine and transaxle module. The implement also includes ground engaging wheels attached to the transaxle axles, a handle allowing control of the implement, and one of a plurality of interchangeable working devices attached to the engine and transaxle module. For example, the implement may be a snow thrower having an auger assembly which is operatively coupled to one of the engine and the transaxle. The transaxle may include a pair of axially aligned axles which are selectively coupled together, such that when the axles are coupled together, the wheels are rotatably fixed together, and when the axles are not coupled together, the wheels are free to rotate relative to each other. The transaxle may further include a pair of housing portions, at least one housing portion having a pair of recesses in which a pair of bushings are respectively disposed, each bushing supporting an end of each of a pair of shafts of the reduction gearing of the transaxle.
