In previous years we have had over 100 tractors competing in ten classes, in 2021 we had a record 116, from under 2500 lbs (Ultra Flyweight) to 12000 lbs (Class 6). This includes four weight classes for the lighter tractors under 4000 pounds. Weight classes and pull rules are posted at the bottom of the page. We have a drive-on electronic scale for determining tractor-with-operator weight. Vintage tractors must be "stock" 1960 and older to compete, and all competitors are welcome. Non-stock vintage tractors can participate in demonstration pulls.
