ABSTRACT:
An extension cone for a cutter for a hydraulic dredge. The cone has spiral helical blades with an opposing helix to the cutter head to force the material forward as the cutter rotates, thus smoothing the bottom and returning any material which was cut and has passed the cutter head back to the suction orifice.
