ABSTRACT:
An improved cutter head for a floating dredge of the type having a lowerable boom with cutter head on the lowerable end thereof. The cutter head includes a rotatable open axis cage of cutter bars mounted adjacent to and along a rectangular suction inlet so that material to be shredded and sludge material are drawn into and through the rotating cage for shredding. Teeth are mounted on the cage bars for digging and breaking dredge material encountered by the teeth. The cage is connected to a drive plate having shock absorbing grommets which absorb axial, tangential and radial shocks received by the rotating cage.
