Abstract
An implement wheel assembly includes two individual wheel arms tied together by a linkage that pivots about a fore-and-aft extending axis at a location above the wheels and generally above the plane of the implement frame. The linkage constrains the wheel arms to pivot in opposite vertical directions as the implement moves over irregular ground surfaces to improve weight distribution on the wheels. Spring structure may be interposed between the ends of a pivoting linkage and the individual wheel arms to lower frame impact forces. The structure allows two wheels to be placed side-by-side with their axes generally aligned and reduces under-frame hardware to improve crop and soil and trash flow.
