Abstract
Removable bucket wheel teeth are provided with a rectangular-in-cross section shank portion and forwardly sloped shoulder areas for insertion into a complementarily-configured socket in a bucket lip. The resulting assembly is much more rigid and wears better than prior art tooth and lip configurations and tends to fracture preferentially when overstressed.
