A method of constructing an improved attachment or implement for use with equipment connected to a coupler is provided. The implement has a crossbar which is one of machined, cast or extruded to provide a cross section within at least the connection zone which lacks welds while still providing parallel flats for connecting to a channel in the coupler. The cross section in the connection zone is void-free and seam free.
