Abstract
A transaxle comprises a hydrostatic transmission (HST), an axle, a gear train interposed between the HST and the axle, a casing and a partition. The casing defines an HST chamber and a gear chamber. The HST is disposed in the HST chamber. The gear train and the axle are disposed in the gear chamber. The partition is disposed in the casing so as to separate the HST chamber and the gear chamber from each other. The partition has an opening through which a hydraulic motor of the HST passes to extend from the HST chamber into the gear chamber so as to be drivingly connected to the gear train. The partition obstructs a flow of fluid between a fluid sump in the HST chamber from a fluid sump in the gear chamber.
