Keck-Gonnerman manufactured tractors, steam engines, and other farm machinery in Indiana. Growing out of a blacksmith shop, Keck-Gonnerman began manufacturing kerosene tractors in 1917. Several standard-tread tractor designs followed, but Keck-Gonnerman tractor designs did not keep up with the rapid changes of the 1920s and tractor production ended by 1937. Production of other equipment, including combines, continued until 1955.
