ABSTRACT:
A wing folding or lift kit adapted to be easily installed on the central frame members of foldable, multi-sectioned earthworking implements to selectively move pivotally mounted side sections or wings. A centrally mounted floating hydraulic cylinder has linkage arms hinged on the ends thereof, with the outer ends of said arms attached, by lost-motion links, to cross members of the wings. In cylinder-extended position, the wings are free to follow ground contour without "working" the cylinder. Upon contraction of the cylinder, the wings are rotated or folded.
