Abstract
A vibratory cable plow assembly including a frame assembly for connecting a plow blade to a frame of a prime mover. The frame assembly supports a vibrating mechanism or shaker that is adapted to impart vibratory movements to the plow blade. The frame assembly includes a lower support that extends rearwardly from its pivotal connection to the frame of the prime mover. The lower support mounts a blade supporting frame for rocking movement about a generally horizontal pivot mechanism. The blade supporting frame is mounted toward a distal end of the lower support intermediate its free ends and has the plow blade attached to a free end thereof. The vibratory mechanism is mounted on the blade supporting frame. An extendable/retractable driver extends about the lower support and is pivotally connected between the frame of the prime mover and the other free end of the blade supporting frame. An elastomeric bearing assembly isolates the blade supporting frame from transferring vibrations to the prime mover. A mounting promotes attachment of the frame assembly to the frame of the prime mover and facilitates horizontal movement of the plow blade relative to the frame of the prime mover.
