Annual Harvest & Kuchen Festival

The Twin Rivers Old Iron Harvest & Kuchen Festival is an annual show that highlights the history of agriculture as well as the history of the machines that were used in years gone by. It also celebrates South Dakota's official state dessert: Kuchen. There will be parades on Saturday and Sunday, an antique tractor pull Sunday afternoon, and threshing demonstrations. There is fun for the whole family including vendors, playground equipment, and train rides for the kids. Lunch is available on the grounds, which are on the western edge of Delmont. Admission is free. Happening September 13-14, 2025, the festival will feature International Harvester. Kuchen will be for sale both days.
