Tractor Info


The Co-op tractors were originally built by Duplex Machinery Company, Battle Creek, Michigan. Duplex sent one of their Co-op No. 2 tractors to Nebraska in 1936, and the results were given in Test No. 275. After Duplex operated for a year or so, the company name was changed to Co-operative Machinery Company, but the 1940 tractor directories list the Arthurdale people as the manufacturer. Shortly after that, the Second World War started, and that about ended the Co-op tractor.
