Abstract: An implement-mounting linkage mechanism for pivotally connecting a frame to a wheeled implement is disclosed. The mechanism is preferably used for pivotally connecting a wheeled load-bearing frame to the backside of a wheeled farm implement. The frame includes wheels adjustable relative to the frame for raising and lowering the frame relative to the ground. The frame preferably includes a plurality of soil-engaging ground-tool implements mounted thereon. The mounting-linkage mechanism of the present invention incorporates a novel non-parallel four-point design which virtually eliminates negative hitch weight when the frame is raised above the ground, in the static case. On the other hand, the novel design results in a net downward force being imposed upon the ground-tool implements when the frame is lowered for soil engagement, in the dynamic case.
