摘要：
TITLE: PULLING HITCH FOR AGRICULTURAL IMPLEMENT A pulling hitch for connecting a plurality of transverse agricultural implements to a single towing vehicle for both field and road usage. First and second rigid horizontal frames respectively tow a pair of independent transverse implements. The first frame is towed behind a tractor by means of a pivotable tongue. The second frame is pulled from the rear of the first frame. It is pivotable between a laterally extended position for field use, and a rearwardly extending position for road travel. Extensible braces or cylinders are utilized to locate the second frame relative to the first, and to locate the pulling tongue of the first frame relative to it.
