A tool-carrying implement having a center section and a pair of outer sections extending transversely from opposite ends of the center section. The center section supports a pair of carriers that shift transversely on the center section and each carrier supports a vertical pivot at its inner end. The inner ends of the outer sections are connected with the respective outer ends of the carriers and a hydraulic cylinder is provided on the center section for shifting the carriers transversely to swing the outer sections rearwardly about the pivot and rotate the tools carried on the outer sections behind the tools carried by the center section to avoid interference therebetween.
