Abstract

A landfill bucket for use with a conventional loader or other type tractor vehicle wherein the bucket is so constructed as to also be usable for dozing, spreading and carrying. It has particular utility in connection with solid waste disposal in that it can serve all the functions required for digging and filling trenches, and in addition can segregate large items out of piles of refuse for special handling.
