ABSTRACT:
A self-contained dredging module includes a unitary body adapted to be attached to the stick of conventional back hoe apparatus to convert it with minimum modification from dry land to sub-aqueous excavation. The body carries a dual cutter wheel, suction pump, and separate motors for driving the cutter wheel and the pump. The cutter wheel is arranged on the module in such a position that dredging is permitted when the stick is moved in one direction and also permitted when the stick and module are turned upside down and the stick is moved in the opposite direction.
