Separate left and right hydrostatic transmission (15) for controlling rotation of left and right final drive wheels (11) of a working vehicle independently are disposed laterally inwardly of the drive wheels in a vertical posture such that, while an input shaft (23) extends upwardly, an output shaft (24) extends downwardly. To each of the hydrostatic transmissions is attached a L-shaped gear box (16) which extends over lower and outer sides of the hydrostatic transmission and supports the axle (17) of final drive wheel at its upstanding portion. within the box is housed first and second reduction gear trains which form a L-shaped transmission path between the output shaft and axle.
