Claim:
A density control system for use in cooperation with a packing machine that is adapted to move forwardly with respect to a ground surface as the machine packs material into a container, the density control system comprising: a material-forming enclosure having an intake end configured to couple to a packing machine and configured to receive material to be packed, and an output end extending rearwardly away from the packing machine and configured to receive a container; and at least one drag member including a first and a second drag strap operatively coupled to the packing machine and configured to extend rearwardly beneath at least a portion of the container to resist forward movement of the packing machine; wherein at least one of the first and second drag straps has at least an upper surface and a lower surface; wherein at least a portion of the upper surface is adapted to be disposed in frictional contact with at least one of a portion of the container and a portion of the packed material; and wherein the lower surface is adapted to be disposed in frictional contact with a ground surface.
