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. In a first embodiment, 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 first embodiment of the disclosed plow assembly provides remote steering, blade pitch, boom tilt, and depth adjustment and the entire assembly may be raised by piston-cylinders, about the transverse horizontal pivot, for transport. In a second embodiment of the cable plow, the rear of the assembly is supported on V-shaped struts, and the plow frame is supported within the opening formed by the struts on converging upper and lower links. The upper links are longer than the lower links to permit an attack angle for the blade which works well in a variety of soil conditions as well as an elliptical motion of the blade which reduces the forces required to pull the blade through the ground.
