Abstract
Wings of multiple section farm implements are folded by hydraulic cylinders each having a knee joint between the piston rod and a single arm which swings against a lug on the wing as the rod is actuated to lift the wing. A trunnion-notch arrangement operating in conjunction with a lost motion connection and an anti-jackknife device maintains a rod-arm interlock during a portion of each cycle of swinging of the wing to and from its folded position.
