A ground working apparatus has a plow assembly including a frame formed with an attached runner and a plow tool. A linkage assembly couples the frame to a bridle assembly for movement of the plow assembly between raised and lowered positions relative to the bridle assembly. The runner and the plow tool depend downwardly from the frame to concurrently run over and plow, respectively, ground to be plowed along a plowing path ahead of the bridle assembly and the plow assembly, wherein the runner sets the frame of the plow assembly at a fixed elevated position with respect to the ground to be plow.
