US 2011/0079405 A1 · Agricultural Implement Walking Beam Assembly

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.

Dependent claims

An implement wheel support structure for supporting an implement frame for movement in a forward direction over level ground and over irregular ground surfaces, the wheel support structure comprising:

first and second wheel arms having upper and lower ends and connected at the upper ends to the frame for rocking in an upright plane about arm axes generally transverse to the forward direction;
ground engaging wheels connected to the lower ends of the wheel arms at transversely offset locations relative to each other;
a transverse beam connected to the frame for rocking about a beam axis generally transverse to the arm axes, the transverse beam having first and second ends;
and
means operably connecting the first and second ends to the first and second wheel arms for constraining the wheel arms to move generally in opposite vertical directions as the frame passes over the irregular ground surfaces to maintain a generally uniform load on the wheels.
