  • Mounting of a steerable wheel
    Patent number: 4821834
    Abstract: A mounting of a steerable wheel, in particular a driven wheel, which is carried on a front axle of an agricultural tractor, has a pivot axis which is displaced horizontally rearwardly with respect to the center of rotation of the wheel. The pivot axis is inclined to provide a positive caster. The horizontal displacement shortens the spacing between the pivot axis and the rearward end of the wheel so that the wheel can be turned to a greater extent before it strikes against the body of the motor vehicle.
