The disclosed vibratory cable plow has a generally horizontal boom supported on transverse horizontal and vertical pivots and a trailer supported on the boom by a vertical pivot. A plow blade is supported on a vibration isolating frame beneath the trailer and the rear of the assembly is supported on wheels which are pivoted by piston-cylinders to control the depth of penetration of the plow blade. The disclosed plow assembly provides remote steering, blade pitch and depth adjustment and the entire assembly may be raised by piston-cylinders, about the transverse horizontal pivot, for transport.
