Abstract
Hitch structure for towing first and second implements forwardly one behind the other in a transport position and in a side-by-side relationship in a field-working position. The hitch structure includes an elongated rear hitch pivotally connected to a rear corner of the first implement by a 180 degree horizontally folding hinge and rockable by a rear hydraulic cylinder between a transport position wherein the rear hitch connector for the second implement is centered behind the first implement, and a field-working position wherein the connector is offset to one side of the first implement. A fore-and-aft extending forward hitch includes an aft end pivotally connected to the first implement at a location offset to the side of the implement and a forward connecting end attached to a towing vehicle. A forward hydraulic cylinder rocks the forward connecting end between a transport position, generally centered with respect to the first implement, and a field-working position wherein the forward connecting end is centrally positioned between the implements. A rear hitch brace is responsive to forward hitch movement to automatically move into and out of a latching support position as the implements are moved to and from the field-working position.
