Tractor Info


The Co-op No. 2 model was of conventional four-wheel design with 11.25 x 28 inch rear tires. It weighed 4,050 pounds and used a Chrysler engine with a 3 1/8 inch bore and 4 3/8 inch stroke. A Co-op No. 3 model was identical except that it used a 3 3/8 x 4 1/2 inch, six-cylinder Chrysler engine. In 1938, the Cooperative Manufacturing Company at Battle Creek offered the same three models. After 1938, neither company appears in the tractor directories.
