Abstract
This invention relates to a hydraulic servomotor-actuated folding mechanism for swinging the hinged extension of an implement frame horizontally between an extended and a retracted position characterized by a two-part foldable strut, the adjacent ends of its sections being hingedly interconnected for pivotal movement, a first link connected between the piston rod of the servomotor and the foldable strut section, and a second link pivotally connected to the main strut section at a point displaced from the pivotal connection between its sections, said second link having its other end connected to the first link at a point intermediate its ends so as to cooperate therewith and with the strut sections to define a pair of fixed length lever arms movable upon actuation between a crossed relation and a side-by-side relation to effect folding and unfolding of the strut.
