ABSTRACT:
A cutting tool for an excavating machine is described which comprises a support arm having an inner end adapted to be movably mounted on the machine and an outer end, a shovel member having a substantially flat working face and carried by the support arm at its outer end, and a plurality of cutting teeth arranged to contact the material to be excavated in advance of the said shovel member and fixed rigidly thereto, the arrangement being such that the said working face is substantially perpendicular to its direction of motion as it contacts the material to be excavated. Assemblies of such cutting tools are also described, which are particularly smooth and efficient in operation.
