A two-way pivot alowing two degrees of rotational freedom is attached at a free end of the first extending leg and to the implement. The two-way pivot allows pivoting an axis perpendicular to the plane of the U-shaped ember and about an axis parallel to the first, extending leg. An attachment device is also provided for removabley attaching the U-shaped to a bar pulled by the vehicle. The attachment device is mounted for rotational movement about an axis parallel to the connecting leg at a free end of the second extending leg. Preferably, the attachment device is located in the open area of the U-shaped member and an extension is provded of the connected leg extendng away from the second extending leg. At the end of the extension, a second attachment device is provided for removably attaching the U-shaped member to a second vehicle.
