An aquatic weed cutter has a continuous cable strung along the horizontal and vertical members of an inverted T-shaped cable frame. The cable is moved by a motor drive in a circuit between opposed sheaves on the ends of the horizontal and vertical members. The drive comprises a pair of engaging belts which hold the cable therebetween and drive it about the circuit. Cutting clips are attached at spaced intervals to the cable for cutting the stems of underwater plants.
