A cutterbar control system for an agricultural or highway mower having a longitudinally rotatable pull bar connecting the tractor hitch frame and the drag bar. The cutterbar gag link is connected to the pull bar at a point removed from its axis of rotation and a float spring and lifting chain are mounted to the pull bar to rotate it against the load imposed by the cutterbar gag link. The pull bar is extendible in response to overloads imposed on the cutterbar.
