Gilson Lawn tractors by series

Gilson was a US manufacturer of mowers, tractors, and other outdoor equipment for most of the twentieth century. Founded in 1911, Gilson became a major manufacturer of residential power equipment in the 1960s with the purchase of Gearo, Versch, and Burns. In addition to their own brand, Gilson also manufactured lawn tractors for Montgomery Ward and Ford. Gilson was sold to Outboard Marine Corporation (OMC) in 1987 and merged with OMC's Lawn Boy group. Lawn Boy was sold to Toro in 1989 and the Plymouth, Wisconsin factory ceased production in 1990.
