A removable wheel tread adjusting device used for facilitating the axial displacement of a tractor wheel assembly is adaptable to the exterior surface of the wheel assembly and can be utilized for the same task on similar wheel assembly structures. Specifically, the removable adjusting device supports a gear which intermeshes with a rack extending lengthwise along the axle and is capable of receiving torque from a tool so as to effect the axial displacement of the wheel assembly relative to the axle. |
