ABSTRACT:
A pair of tool beams with support hitches for ground working implements, the support hitches being placeable at desired positions along the tool beams. By placement of hitches at desired positions, old and new implements for working different numbers of rows may be pulled by a large tractor. The tool beams are connected through linkages or hinges to a forward draft beam such that the tool beams can be turned from a transverse working position to a longitudinal, trailing position for transportation. In the position for transportation, the implements are positioned toward a center line between the tool beams. The hitches for the implements are connected to the tool beams through power lift supports for raising the implements, and the implements are held in a raised position while being transported and while the tool beams are being folded and unfolded.
