An axle drive apparatus of compact construction with improvements in the arrangement of the hydraulic speed change gearing and axle, and in the configuration of the transmission case. In the transmission case, there are horizontally disposed, when viewed in side elevation, a pump shaft of the HST type speed change gears on the upper side of the axle and a motor shaft of the gears on the lower side of the axle, in such a way that the shafts are longitudinally staggered. A movable swash plate is disposed below the pump shaft. The transmission case consists of two split case portions, in one of which are housed, at one side of its front portion, the HST speed change gearing and, at the other side of its rear portion, the output shaft of the motor shaft and the axle, the front portion of the one split case portion being closed by a center section, the rear portion being closed by the other case portion.
