A wheel arm assembly for an implement includes a common wheel arm for sing le wheel, straight tandem wheel, or walking beam configurations. In the straigh t 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 throu gh a selectively attachable walking beam casting and through the bushings in the arm. The sam e spindles that attach the wheels to the arm in the conventional tandem configuration a re inserted in the offset ends of the walking beam to support the wheels from the walking beam casting.
