The disclosed vibratory cable plot has two in line plow blades supported on a trailer having a transverse horizontal pivot and a vibrator which imparts a rocking oscillatory motion to the trailer and the blades. The first blade is preferably shorter, but thicker than the second trailing blade. The second blade is longer than the first blade and has a trailing cable guide guiding flexible cable, pipe and the like into the slot cut by the blades. The double blade assembly is more efficient than a single blade and reduces blade wear.
