Abstract
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.
Claims16
A method of manufacturing an implement with an improved crossbar connection comprising the steps of:
- a) extruding a crossbar independently of welding to provide a void-free and seam free cross section at least in a connection zone internal to an attachment portion having parallel flats, said flats spaced apart about a circular exterior surface of the crossbar;
- b) connecting said crossbar securely to an implement whereby said parallel flats cooperate with a channel of a coupler whereby when the implement is connected to the coupler, the flats contact against opposing sides of the channel in a connected configuration, and one of said flats and coupler rotated relative to the other whereby the flats are out of connection with the sides of channel through rotation to thereby permit disengagement of the coupler from the crossbar.
