ABSTRACT:
A hydraulically operated folding mechanism for ground working implements wherein substantially rectilinear movement of the piston rod of a hydraulic actuator causes one section of the implement to rotate substantially 180.degree. relative to another section thereof. This enables a relatively large implement to be made small and compact for purposes of storage and transport. It further includes members for permitting the several sections to pivot relative to each other when in operating position so that the implement can conform to the contour of the ground and locking structure which prevents such pivotal movement as soon as the folding mechanism becomes operative.
