<p>A tractor with excellent steering operability. In the tractor, a front axle case extending in the left-right direction is installed on a machine body frame and both members of a pair of left and right front wheels are installed on left and right end sections, respectively, of the front axle case with left and right gear cases in between, respectively. The left and right gear cases are each composed of a fixed side case molded body attached to a side end section of the front axle case and of a pivoting side case molded body attached through a knuckle arm to the fixed side case molded body so as to be pivotable about a vertical axis. A pivoting restricting section is projectedly formed on the fixed side case molded body, and a pivoting restricted section is provided on the knuckle arm. This causes the pivoting restricted section to engage with the pivoting restricting section to restrict the pivoting of the pivoting side case molded body through the knuckle arm.</p> |
