A plurality of ground working sections such as cultivator sections, are flexibly connected together and operatively connected to a hitch pole assembly. Each section is supported upon a pair of castor wheels mounted on a fore and aft beam pivotally connected to the front and rear of the frame members. The sweeps or cultivators move in an arc via hydraulic or mechanically operated rock shafts and the depth control is by means of controlling the pivotal movement of the fore and aft beams. This also permits the penetration angle of the sweep or cultivator to be preset and maintained. For transport, the draw pole is raised and the implement is towed by one end thereof with the castor wheels automatically aligning with the direction of travel thus eliminating folding or raising of sections and permitting practically any length of cultivator or ground working implements to be assembled.
