ABSTRACT:
An articulated-boom hoist is attachable to a motorized vehicle and structured to transfer an aquatic rake and rake float between a carrier and a body of water to be cleaned of aquatic plants. The aquatic rake is placed on the rake float. The rake float on the body of water is propelled to a select distance from the motorized vehicle. The aquatic rake is then removed from the rake float, dropped into the body of water and pulled towards the motorized vehicle with a winch and winch line attached to the motorized vehicle which is anchored appropriately in resistance to the winching action. Aquatic plants are uprooted from a bed of the body of water thereby. The articulated-boom hoist is then employed to lift the aquatic rake with aquatic plants gathered thereon from the body of water and position it above a transport vehicle or other dump site. The aquatic rake is tilted appropriately to cause aquatic plants to drop from it. Then the aquatic rake is repositioned back on the rake float to repeat the process as desired. The articulated-boom hoist can be either vertically swivelable or both vertically and horizontally swivelable, depending on use-condition tradeoff factors. If the articulated-boom hoist is horizontally swivelable, the motorized vehicle to which it is attachable need not be moved to dump aquatic plants from the aquatic rake. A float boom is optional for positioning the rake float with the aquatic rake thereon for drag-line cycles of operation.
