Wisconsin Tractor Farm tractors by year
The Wisconsin Tractor was the product of the McFarlane family. After moving the blacksmith and farm equipment company from Lodi to Sauk City, Wisconsin, the production of farm tractors began. The company produced nearly 500 tractors when crop failures, and the resulting loss of payment, stopped production in 1925. The family business still exists to this day, with farm machinery and metal fabrication.
