ABSTRACT:
In an earth working implement having a wing frame which is rearwardly foldable, and with elongated, flexible cables which extend rearwardly and outwardly from a main frame of the implement to the outer ends of the wing frame, apparatus is provided for preventing slackening of the flexible cables when the wing frame is folded from an operating configuration to a transporting configuration, or vice versa. The flexible cables are thus kept from sagging to the ground and tangling during folding and unfolding of the implement. One end of each of the cables is attached to the outer end of an arm member, with the inner end of the arm members being pivotally attached to the main frame for back and forth pivoting of the arms. 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 a yoke pivotally attached to the main frame. The arms are unlatched and swing outwardly and rearwardly when the wing frame is folded rearwardly and inwardly to a transport configuration.
