The kingpin is operatively connected to the front axle through a bevel gear transmission, and the hub shaft is operatively connected to the kingpin through a bevel gear transmission and a planetary reduction mechanism. The front wheel has a substantially zero camber angle, and the kingpin is inclined such that a lower portion of the transmission case disposed inwardly with respect to a center of the tractor is substantially contained inside a rim of the front wheel.
