The history behind the manufacturing of Co-op tractors is complicated and moved all over the United States. This Co-op tractor No. 3 was made in 1948 and designed by Dent Parrett. Parrett is the designer of the No. 1, 2 and 3 Co-op tractors and worked for the Parrett Tractor Company in Chicago from 1913 to 1922 when the company went under. More than 10 years later in 1937, Duplex Printing Press was dismissed as the manufacturer of the Co-op tractors and replaced by Co-operative MFG at Battle Creek, Michigan. Then, in 1940, the Co-op tractors changed manufacturers to the Farmers Union Central Exchange St. Paul, Minnesota. After five years the manufacturer changed again to Arthurdale Farm Equipment, West Virginia. The manufacturer changed one more time in the 1940s to the National Farm Machinery Co-op in Shelbyville, Indiana, but the Co-op tractors fell out of production soon after WWII.
