摘要： An underwater weed-cutting device comprising a longitudinally adjustable shaft for immersing in a body of water, a drive motor mounted at one end of the shaft and cutting blades mounted at the other end of the shaft. A submersible float is adjustably mounted on the shaft intermediate its ends and contains an independently driven chopper mechanism an a suction device adapted to suckup and finely chop the weeds cut off at the bottom of the body of water for disposal, the intermediate submersible float being provided to maintain balance of the cutting device, to adjustably raise or lower the cutting blades in relation to the various depths of the body of water, and to vary the height of the chopper mechanism relative to the height of the weeds.
