The predecessor of Waterloo Boy came about in 1892. It was built by thresher-man John Froelich. It was called the Froelich tractor. But it did not sell well. But then they developed it more and came up with the "Waterloo Boy" design in 1913. This was more successful, selling 8,000. The Waterloo Gasoline Engine Company successfully made three models of 2-cylinder tractors namely the L and LA and the very successful model R. see for more details:- Waterloo Gasoline Engine Company
