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.

Abstract: A vibratory plow blade which increases the efficiency of the plowing action. The tapered leading edge of the plow blade includes a plurality of saw-like teeth or serrations. The uppermost serration acts as a soil cutter as the plow blade moves along the ground slot formed by the blade during vibration, thereby relieving surface tension created by packed soil or sod. The intermediate serration provides an upward fracturing of the subsoil with each successive up stroke from the vibratory action. This fracturing reduces the amount of work required to move the plow blade through the soil in the direction of plowing. The lower serration also provides an upward fracturing of the deep subsoil directly above the serration. Further, the upper leading edge of the lower serration is sloped to a greater extent than the upper leading edges of the other serrations to provide blade pull for maintaining the proper plowing depth during the plowing operation.

Abstract: A vibratory plow assembly which eliminates the need for elastic torque cushioning elements. The plow assembly includes a vertically extending support frame and a vertically extending shaker frame having an elongated plow blade attached thereto with an oscillating mechanism supported on the shaker frame for reciprocating the shaker frame and plow blade. The support and shaker frames are interconnected adjacent their upper ends by conventional connecting links. The lower ends of the support and shaker frames are interconnected by a generally planar, horizontally disposed, spring plate member which is fixedly attached to the support frame at one end and is secured to the bottom of the shaker frame at its opposite end. The spring plate member withstands the loading imposed upon it by the shaker frame and plow blade while being flexible to deflect vertically thereby permitting the vibratory motion from the oscillating mechanism to be transmitted to the plow blade.
