Keeping the Heritage Alive
Celebrating our 54th Show August 8-10, 2025
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.
