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.
