Abstract: First and second pairs of wheels are mounted to respective sides of a grain cart in a manner which avoids tire "scrubbing," such as when a tire is forced sideways over a support surface without rotation, as the cart is displaced in a turning manner over uneven soil. Each pair of wheels includes an inner and an outer wheel coupled together by pivoting linkage which allows each wheel to move either upward or downward over uneven soil while vertically displacing the other wheel in the opposite direction. On level ground, the linkage provides a positive camber for a pair of inner and outer wheels, with lower portions of adjacent wheels in contact with the soil more closely spaced than upper portions of the wheels. As the relative elevation of the wheels changes as the cart traverses uneven soil, wheel camber changes from positive to negative, wherein upper portions of adjacent wheels are more closely spaced than lower portions of the wheels.
