ABSTRACT:
A agricultural implement incorporates a frame which is adapted to engage a three point hitch of a tractor. The frame employs a longitudinally extending member which is pivotally connected to a link member. A resilient yielding assembly is disposed between the longitudinally extending member and the link member to absorb forces exerted from the link member onto the longitudinally extended member. Accordingly, when the link is acted upon by forces which cause the link to exert a stress on the three point hitch of a tractor, the resilient yielding assembly allows the first link to pivot about the longitudinal member thereby reducing compressive loads exerted on the upper link of the tractor's three point hitch.
