Abstract A latching yoke is pivotally attached to the main brace of an earth working implement having a wing frame which is rearwardly foldable. Elongated, flexible cables extend rearwardly and outwardly from the main frame to the outer ends of the wing frame and arm members, pivotally attached to the main frame, receive one end of the cables for preventing slackening thereof when the wing frame is folded from an operating configuration to a transporting configura- tion, or vice versa. A wing frame lifting tower is on the main frame and has a lever operating an actuator rod. When the wing frame is in the operating configuration, the arm members are folded forwardly and inwardly and the outer ends thereof are latched by the yoke which has an opening through which the rod extends and is freely movable. Adjustable yoke engaging members are spaced along the rod to determine the positions of the wing frame when the arms are latched for operation and unlatched for transport configuration.
