Abstract
A compact integrated transaxle has a two-piece transaxle casing for rotatably mounting a pair of oppositely extending axles along a peripheral seam formed between an upper casing part and a lower casing part. A hydrostatic transmission is also mounted in the transaxle casing and has a center section positionable in the transaxle casing with a pair of perpendicular faces each mounting a hydraulic displacement unit. One of the center section faces defines a hydraulic pump mounting surface and is offset from the plane defined by the peripheral seam. A counter-rotating intermediate shaft is interposed between an output shaft on one of the hydraulic units and the axles and is journalled within the transaxle casing offset from the plane defined by the peripheral seam.
