摘要： A weed removing apparatus suitable for grubbing weeds from a lake bottom. The apparatus includes a land-based unit including a combustion engine driving an hydraulic pump, and a separate submersible unit including a hydraulic motor which is driven by the hydraulic pump of the land-based unit via an elongated hose. The submersible unit incluldes a rotatable drum including several tines extending radially outward therefrom for grubbing weeds and which is driven by the hydraulic motor. The submersible unit includes wheels which are propelled by the hydraulic motor. A handle extending from the submersible unit provides a steering mechanism to the operator for guiding the submersible unit about the lake bottom in the area desired to be cleared of weeds. The land-based unit further includes a take-up reel for storing a substantial length of hose when not in use. The hose also includes several spaced-apart flotation devices for buoying the hose upon the water surface to avoid entanglement and snaring about the lake bottom or with weeds. The submersible unit is easily maneuvered and has a large range, and thus is adaptable to a large area of shoreline. The tined drum removes weeds by the roots such that weed regrowth is substantially inhibited. The submersible unit can be used in various depths of water by using an extension handle and is easy to use since the wheels are cleated and propelled by the hydraulic motor. Thus, a mechanized apparatus is provided to reduce the labor required to remove lake weeds.
