ABSTRACT:
A disk harrow embodies a fore-and-aft extending center pole which hitches at one end to a tractor and has paired tool gang assembly units which extend laterally from opposite sides thereof. These units include tool gang carrying inner beams which are supported on transport wheels and are connected to said pole for horizontal adjustment about pivots spaced along the longitudinal axis of the pole, one behind the other. Adjustable length truss bars connected between the pole and the inner beams releasably lock said tool gang assembly units in a transport position generally perpendicular to the pole. The tool gang assembly units also include a tool gang carrying outer beam which is hinged to the inner beam to fold vertically thereover onto the pole when the units are perpendicular thereto. The spacing of the pivots provides sufficient clearance that the folded outer beams lie flat with their tools in close side-by-side relation on the pole for transport.
