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. Finally, the bottom edge of the plow blade is tapered to reduce soil resistance as the plow blade is returned to the lowest point in the stroke during vibratory motion for wedging the soil away from the blade.
