  • Patent number: 5493850
    Abstract: A plant gathering apparatus for the removal of aquatic plant growth on lake bottoms includes a mobile frame adapted for towing across a lake bottom, a raking mechanism, a towing assembly, an actuating mechanism and a cleaning mechanism. The raking mechanism mounts to the rear end of the frame to undergo pivotal movement between a raised inoperative position and a lowered position in which the raking mechanism is adapted to engage and gather aquatic plant growth as the mobile frame is towed across the lake bottom. The towing assembly mounts to the front end of the mobile frame for use in towing the mobile frame and is rotatable relative to the mobile. The actuating mechanism mounts to the mobile frame for moving the raking mechanism between the lowered and raised positions in response to rotation of the towing assembly.
