Keeping the Heritage Alive
Celebrating our 55th Show August 6-9, 2026
The very first Threshing Show was held in August of 1971. The Threshermen and Collectors Association was formally organized on December 11, 1974. On October 31, 1975, the members of the Association voted to accept a land gift of 15 acres from Ed and Agnes Sundholm for the development of the “Heritage Site”. From its humble beginnings, the Association has poured itself into and grown one of the best collector shows in the region. With the help of loyal volunteers, exhibitors and patrons, the show’s future will shine on for generations.
2026 Show Feature
Old Power Round-up and Wheat Run
The rumors are true – next year will be a four-day show! Our 55th annual Threshermen & Collectors Show will feature the Old Power Round-up and Wheat Run on August 6-9, 2026. Directors Brady Bonin and Grant Stein had the idea to do a unique feature event like this and have been working on it for several years. What is unique about this idea is that all makes will be a part of the feature rather than the typical focus of just one make of machinery. It will highlight the big power used on the farm prior to the 1930s. Visitors can expect to see big and small steam engines, huge prairie tractors, and much more. In the field you can expect to see around 20 combines running to give a visual of what a custom harvest crew might look like. In our threshing area, we will also demonstrate what that might have looked like pre-1930. You can expect to see around 7 separators threshing wheat to bring the wheat run to full circle. As the combines harvest, you can also expect to see the rakes, balers, and plows following up. This will truly be a show you won’t want to miss!
