Abstract
A cable feed subassembly for use with a vibratory plow in placing a cable or tube in the earth. The plow includes a plow blade and an associated vibratory unit. A cable guide assembly is mounted on the rear side of the plow blade and an incremental cable feed subassembly is mounted in association with the vibratory unit so as to be oscillated in synchronism with the vibratory cycles of the vibratory unit. The cable feed subassembly includes a pair of cooperating rollers through which the cable is passed, and by which it is forced downwardly by the periodic, incremental rotation of at least one of the rollers.
