ABSTRACT:
An agricultural tool bar includes a main frame adapted to be drawn by a traction vehicle. First and second tool support beams are pivotally mounted to the main frame. The tool support beams are adapted for movement between a use position and a road travel position. In the use position, the axes of the tool support beams are collinear and extend transverse of the direction of travel of the vehicle, and in the travel position, they are folded rearwardly. An articulated link is provided for each tool support bar, selectively holding it either in the use position or the folded position. The main frame and tool support beams may be raised relative to the ground so that the tool support bars do not have to be rotated about horizontal axes prior to folding.
