A wheel arm assembly for an implement includes a common wheel arm for single wheel, straight tandem wheel, or walking beam configurations. In the straight tandem configuration, a pair of spindles are supported in corresponding bushings at the end of the wheel arm. The spindles are axially aligned, project outwardly from the arm, and support a pair of wheels in tandem. To convert to the optional walking beam configuration, the operator removes the spindles from the bushings and inserts a long pin through a selectively attachable walking beam casting and through the bushings in the arm. The same spindles that attach the wheels to the arm in the conventional tandem configuration are inserted in the offset ends of the walking beam to support the wheels from the walking beam casting.
