Visitors can now explore the Tri-State Antique Engine and Threshers Association buildings year-round. Begin at the visitor center to plan your route through more than 30 buildings housing hundreds of tractors. In addition to vintage farm equipment, the site features an antique car museum, creamery, church, sod house, blacksmith shop, and print shop. Exhibits also highlight domestic life, including kitchens from the late 1800s and 1950s. Don’t miss the 1922 wooden self-propelled combine by Charles Holt—an innovation that helped lead to Caterpillar—or the Depression-era Hoover wagon.
