<p>A vehicle traction arrangement where wheels 1, 3, 20, 30, 60, 70 are arranged to be subjected to differing torque bias or steering angle relative to other wheels 1, 3, 20, 30, 60, 70 in order that a drag resistance upon soft terrain of the rear wheels of a wheel pair in the depressions created by the front wheels is diminished. In a first embodiment, the rear wheels are provided with greater torque relative to the front wheels in a wheel pair. In alternative embodiments the front and rear wheels in a wheel pair are arranged to have drive paths which alternate either side of a nominal line A-A of drive direction so that they do not substantially coincide and the rear wheels when driven in a straight line do not have a significantly greater drag compared to the front wheels of a wheel pair. <IMAGE></p> |
