The tillage implement has tool beam assemblies that project laterally outwardly in opposite directions from the central fore-and-aft axis of the implement, and the inboard ends of the assemblies are overlapped transversely with respect to the path of travel of the implement while also being offset in a fore-and-aft direction so that the soil worked by the inboard end of the leading tool assembly is reworked by the inboard end of the trailing tool assembly to eliminate the formation of a furrow or ridge at the point of convergence of the tool assemblies. Notwithstanding the overlap and offset, the assemblies may be swung back into folded positions for transport in which the assemblies are substantially parallel to one another in order to reduce the overall roading width of the implement.
