Abstract
A vibratory plow blade having a tapered leading edge, a trailing edge, and a tapered bottom edge wherein the plow blade is configured such that its longitudinal axis regresses or is arcuately angled away from the towing vehicle. The tapered leading edge of the plow blade includes an upper straight cutting section and a plurality of forward angled serrations along its length which provide for downward and upward cutting and fracturing of the soil with each successive stroke of the blade during vibratory action. The guide chute for the cable is mounted to the trailing edge at a substantial bend radius for reducing the flexing required of the cable and reducing the weight of the guide chute. The construction permits close proximity between the plow blade and guide chute for providing increased chute protection and a reduction in the chute frictional drag thereby leaving more vibrational energy for soil displacement.
