ABSTRACT:
A pipe or cable laying apparatus includes a quadrilateral linkage device mounting the narrow ripping plow to a tractor and a chute body hingedly mounted to the trailing edge of the plow. The chute body includes a cable conduit compartment therein, and a separate chute and hopper for passing particulate materials through the body, and an auger device provided at the bottom of the body. The auger device is hollow and communicates with the cable conduit. The other end of the hollow auger device communicates with a discharge opening in the bottom of the body while the chute provides a steady gravity flow of particulate material to the auger.
