Abstract
A vibratory plow used for laying pipe or electrical cable in the ground is provided with an improved V-shaped oscillating blade. The V-shaped blade has two blade arms that are not connected at their lower ends, so that each blade is free to move in an oscillatory path in the plane of the blade without interference from and independently of the other blade arm.
