Abstract
An integrated hydrostatic transaxle including a housing in which a center section is supported. The center section supports a hydraulic pump unit and a hydraulic motor unit having a motor shaft drivingly connected thereto. A differential assembly is drivingly linked to the motor shaft and is used to drive a pair of axle shafts which are supported by the housing. The differential assembly includes a rotatable gear which is maintained in frictional engagement with at least one bearing surfaces for frictionally inhibiting the rotational movement thereof.
