Abstract

A rake, pitchfork, or similar forked hand tool or tool head for mechanized machinery has welded tines. The tines each have a lower section located on the backbone of the tool head and a working section extending outwardly from the backbone. Each tine also has two lateral surfaces, two vertical surfaces and a transversely extending back edge surface therebetween. In one embodiment, welds extend the full length of one of the lateral surfaces, the full length of a vertical surface, the transverse length of the back edge surface and down the second vertical surface to the junction between the bottom of the vertical surface and the second lateral surface. Welds can also extend partially along the length of the second lateral surface for a distance not to exceed three quarters of its length. These tines have elongated fracture lines. The resulting tool is far less prone to breakage.
