  • Patent number: 5481856
    Abstract: A method and apparatus for cutting aquatic vegetation is provided which substantially reduces the tendency to wrap or clog conventional cutterheads. A cutterhead of the present invention includes a plurality of radially oriented rotatable cutting members which cooperate with stationary cutting teeth to tear weeds and other aquatic vegetation. The rotatable cutting members are preferably spirally mounted along a smooth rotatable drum to inhibit draping of the vegetation during cutting. Recessed cutting teeth are located at the ends of the drum to further inhibit aquatic vegetation from passing through gaps between the drum and the cutterhead shroud. The shroud directs the cut vegetation to a submersible pump so that it may be pumped to a remote site.
