A foldable agricultural implement for use in a towed relationship with a tractor, wherein a pair of outboardly wheeled implement frames or wings carrying ground working tools are rotatably and pivotally supported at their inboard ends by a wheeled rear carrier. The implement frames are connected to the rear carrier by ball and socket joint assemblies and are pivotally and rotatably connected to a towing means by a twin tongue assembly, adapted so that the work performing means are capable of maneuvering and closely following the contours of a field and folding forward and elevating to provide ground clearance for transport.
