Abstract
A wheel arrangement includes a retainer mechanism with a spring-loaded pin mounted on the walking beam of a support wheel assembly on a folding implement. A mating retainer supported on the wheel support tube is normally offset from the pin when the implement is in the lowered field-working position. As the implement is raised toward the transport position and the angle of the beam changes relative to the support tube, the pin settles in a central notch in the retainer. The retainer mechanism maintains a preselected angle between the beam and the support tube as the outrigger is moved upwardly and the outrigger wheels are raised from the ground, thereby preventing unwanted rocking of the walking beam during transport and maintaining the wheels in a noninterfering relationship with other portions of the implement.
