I don’t know much about the Eclipse company at this time. But from what I have found out is that the founder was Fred Adams.
Freed Adams was an Illinois farm boy who later trained as a jeweller. His idea of a self-sharpening lawn mower came way back in 1900.
The next year he started the Eclipse Company in Prophetstown, Illinois. One of the first mowers the company produced was the sidewheel “Lady” mower.
Eclipse also made many other sidewheel models during its early years. In the 1950’s a wide range of powered machines were made.
In 1960 the company was taken over by Hahn.
This is all I know about the Eclipse company now, but will try to find more later on.
If any one has anything else on these mowers or the company, please fill free to comment.
