ABSTRACT:
A harvester and method for harvesting aquatic algae or floating vegetation in shallow areas of water bodies, such as lakes. The harvester is manually operated. The harvester includes a pair of blades which are manually moved by a rope connected to an extension spring, a compressed gas cylinder or the harvester wheels through a metal rod driven system. The harvester provides improved hydraulic flow through a hydraulic friction reducing plastic or metal sheet, a movable plastic or metal bar to adjust the volume of water allowed into the apparatus and vertical hydraulic flow guides to improve flow of water through the apparatus. The aquatic algae or floating vegetation is collected on the harvester, removed from the harvester, dewatered and used for compost in garden and agricultural activities.
