ABSTRACT:
Two cultivators, in combination, form an assembly with a first implement having fixed soil penetrating members and a second cultivator has rotatary soil working members with tines that intensely work the soil broken by the first cultivator. Each cultivator has a corresponding coupling member at the forward portion of its frame and each coupling member is connectable to the lifting hitch of a conventional tractor independently of the other implement. Alternatively, the coupling members can be interlinked to one another with pivotable arms so that each cultivator is independently movable with respect to one another for a limited extent in vertical directions. A supporting roller can be positioned to the rear of the second cultivator.
