Abstract: An apparatus and method for removing water hyacinths. The system of the present invention utilizes a transfer mechanism and grapple to collect hyacinth material from a body of water. The collected material is then passed to a transport for delivery to a header unit and grapple. The header unit grapple then retrieves the hyacinth material and delivers it to a collection bin for processing. The chopped hyacinth material is thereafter discharged for subsequent use as a biomass.

Abstract: An apparatus and method for harvesting aquatic plant biomass, and more particularly, to a system and method for harvesting attached algal communities or algal turf whereby water is utilized to transport algal biomass to a central collection location. Additionally, the apparatus and method of the present invention is drawn to a gathering means whereby algal turf or biomass is severed from the ATS and transferred via a towing method, instead of pushing, thereby reducing potential damage to the ATS.

Abstract: A system for harvesting and processing aquatic plants growing on the surface of a body of water includes a shore mounted harvesting apparatus which gathers the plants from the surface of the water and conveys them to a first chopper assembly which rips and shreds the plants to a first manageable size. The harvester assembly includes a first rotating drum positioned in the water which forces the plants upward and into engagement with a second rotating drum having a plurality of spiral wound vanes which engage the material and forces it along the passageway into further engagement with a third rotating drum which cooperates with a cutting bar to serrate and shred the material. The shredded material is thereafter transferred to a chopping assembly which comminutes the aquatic plants into very small pieces.
