Fellow by the name of Fred Adams started the Eclipse Mower Company in 1902 in Prophetstown, IL. They built outstanding mowers. My understanding is Eclipse was bought out by Hahn, and they moved the operation to Evansville, Indiana in 1961. 1959 was the last year Eclipse mowers were uniquely painted. In 1960 the Eclipse line adopted the yellow and white Hahn color scheme and still bore only the name of Eclipse. They went by the name of Hahn/Eclipse for a bit after the move. They eventually dropped the Eclipse part.
