ABSTRACT:
A vibratory plow particularly suitable for laying cable, pipe and the like underground. The plow blade is pivotally mounted on a frame assembly on a resilient mounting. The frame assembly includes a U-shaped yoke pivotally mounted at opposite ends to the frame assembly. A vibrator is mounted on the yoke and the yoke is pivotally connected to the blade by a link which is pivotally connected at opposed ends to the blade and the yoke. The blade is thereby vibrated in an orbital plowing motion as the blade is drawn through the earth by a suitable vehicle.
