摘要： A steering apparatus for a front wheel drive tractor comprising, at each of opposite lateral sides thereof, a front axle, a front axle case housing the front axle, a kingpin, a transmission case provided in an outer end region of the front axle case to be pivotable about the kingpin, and a front wheel attached to the transmission case and including a hub shaft. 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.
