PROBLEM TO BE SOLVED: To provide a lotus root digger having such a mechanism as to take water inside a lotus pond into a high-pressure pump, ensuring the high-pressure pump or the like not to undergo cloggings even with such water, affording good workability through stably feeding water for digging lotus roots, and easily movable throughout a lotus pond. SOLUTION: The lotus root digger 1 has such a construction and mechanism as to be loaded on a float 8 movable in a floating condition on the surface water layer in a lotus pond and extrude water taken via a muddy water filter 10 through the high-pressure pump 22. In this digger 1, the float 8 is of approximate U-shape seen from the top with only its rear end open, and behind and underneath the float 8, jet propellers 55 functioning to extrude pressurized water from the high-pressure pump 22 are installed respectively.
