ABSTRACT:
Unwanted aquatic weeds are removed by first dragging the bottom of a lake with a horizontal bar to loosen the weeds from the bottom. The uprooted and broken weed stalks are permitted to float to the surface of the lake. The weeds are scooped from the water by a mesh scoop capable of being carried to a dumping area and emptied. The method is carried out by a self-propelled hull having a boom pivotally attached to a forward end thereof. The boom is adapted to receive various implements on its free end. One such implement is a horizontal drag bar with downwardly depending tines to drag the lake bottom and another of the implements is the wire mesh scoop mentioned above. The tines of the first implement each preferably include at least a portion that is angled forwardly, so that when the boom is lowered sufficiently to meet the lake bottom the angled portion of the tine if substantially orthogonal to the lake bottom. The tines preferably are at least partially embedded in the bottom and loosen the root systems of deeply-rooted aquatic weeds. The scoop is pivotally mounted on the boom so that it can be moved by gravity to a dump position that permits gravity to act on the weed stalks and empty the scoop.
