ABSTRACT:
An assembly for mounting an excavating tooth particularly suited for a dredge cutterhead includes a base, an adapter, and a lock. The base includes a convex, curved bearing surface that abuts a concave, curved bearing surface on the adapter. The curved bearing surfaces are able to maintain substantially full contact with each other under transverse loading. The undersurface of the base is formed with a groove to improve the strength and durability of the weld.
