Abstract:
A forward folding agricultural implement frame has a center frame with pivotally connected wings that fold forward for storage and laterally for use. A pair of draft links connects the wings to a telescopic hitch that extends forward from the center frame. A pivot pin operably mounted to a forward portion of the telescopic hitch defines a generally vertical pivot axis. A pivot link is connected to the pivot pin to pivot about the generally vertical pivot axis. The pivot link having a first portion on one side of the pivot pin and a second portion on an opposite of the pivot pin from the first portion. The draft links are pivotally connected to the first and second portions of the pivot link. When the wings are flexed in opposite directions (or when one wing is neutral and the other wing is flexed), the pivot link will permit opposite relative movement of the draft link ends relative to the inner hitch, which reduces internal stress and prevents permanent strain of the components.
