An apparatus for coupling a tractor, a dump trailer and a dump truck wherein the dump trailer is adapted to be selectively towed by the tractor or by the dump truck. A draw bar having a trunnion and a hole at the leading end portion is pivotally mounted on the dump trailer. The trunnion is adapted to be engaged with a gripper mounted on an arm member of the tractor so as to enable the dump trailer to be towed by the tractor. The hole of the draw bar is adapted to be engageable with a coupler pivotally mounted on a rear axle of the dump truck thereby allowing the dump trailer to be drawn by the dump truck.
