  • Patent number: 11440401
    Abstract: A transaxle casing has a fluid sump having a gear top cover, an HST, a reduction gear train and at least one axle disposed in the transaxle casing. The gear top cover accommodates a part of a rotation portion of the reduction gear train. An air supply and exhaust hole is disposed on an upper surface of the gear top cover facing an air sump and is arranged at a position different from a point above a bevel gear. A breather is attached at the air supply and exhaust hole, and a first inner wall extending downward from the upper surface of the upper casing member, is positioned between the part of the bevel gear and the air supply and exhaust hole.
