Abstract

The two gang disc harrow units are pivotally joined near corresponding ends by a vertical axis hinge coupling. Near their opposite corresponding ends, the harrow units are connected by a collapsible toggle linkage which operates in a horizontal plane under influence of a power cylinder, whereby the harrow units can be positioned at a prescribed angle for working the soil and in parallel relationship for transport. Two transport wheels are pivotally attached to the rear harrow unit on transverse pivot axis which are parallel to the rear unit. Power cylinders interconnecting these wheels with the rear harrow unit are operable to lower and raise the wheels for lifting and lowering the rear unit. The front harrow unit has a pivotal connection with a drawbar which in turn is coupled through a draft tongue with the hitch of a towing or transport vehicle.
