A transaxle includes a housing, a hydraulic pump, a hydraulic motor, an axle supported by the housing and disposed in parallel to a motor shaft of the hydraulic motor, a mechanical drive train including an intermediate gear for mechanically connecting the motor shaft to the axle, a center section, an operation shaft supported by the housing so as to operate a movable swash plate of the hydraulic pump, a speed-control operation lever provided on the outer portion of the operation shaft, and a brake rotor provided on the outer portion of said motor shaft. The operation shaft and the motor shaft extend in parallel and have respective outer portions projecting outward from a side surface of the housing. The center section includes a pump mounting surface and a motor mounting surface which are disposed perpendicular to each other and overlap each other in an axial direction of the axle.
