ABSTRACT:
A dredging apparatus having an improved dredging head in which the suction pump and drive motors for the same are mounted adjacent the clean-out and cutting augers for increased pumping efficiency. The augers include a cooperating plurality of cutting teeth mounted peripherally on the flighting of the auger and extending spirally along the same to provide for a continual shearing cutting surface in a line parallel to the rotational shaft of the augers for more efficient cutting of the fibrous materials.
