Working tools with wear resistant working surfaces for agricultural implements and other applications

摘要

A composite working tool, for example a ground engaging tool of an agricultural implement, features a body composed of a first material and an insert composed of a distinct second material of greater hardness than the first material to define wear resistant surfaces of the tool. The tool body has an opening recessed thereinto from an exposed exterior surface fully surrounding the opening on all sides thereof, and the insert is attached to the body in a position at least partially received within the opening, for example by brazing. The increases the wear life of the body and provides greater mounting strength over surface-mounted wear inserts of the prior art.
