Abstract
An implement hitch for ganging multiple implements and towing them forwardly in a field-working position and endwise in a transport position. Trusses extend between hitch assemblies on the implements to provide endwise spacing of the implements. Stabilizers extend rearwardly from the trusses to the front of the implements to maintain the proper fore-and-aft alignment while allowing the implements to move up and down freely over uneven terrain. A main beam pivotally connected to an outermost truss serves as a common link between a towing vehicle and the hitch assembly for both the field-working and transport positions. Transport wheel assemblies mounted near the rear of the implements are provided for raising and lowering the implements to and from the transport position. The inner transport wheel assemblies include means for automatically connecting the adjacent corners of adjacent implements together as they are raised. As the implements are lowered to the field-working position the adjacent corners are automatically disconnected so the implements can move vertically freely with respect to each other.
