Fifth Annual Slepicka Tractor Collection Show

Saturday, June 14 13, 2026 | 10:00 am – 3:00 pm 6675 N. 79th Street, Niwot

Join the Niwot Community Association for the fifth annual Slepicka Tractor Show returns to a private property just outside Old Town Niwot. The collection includes more than a dozen full-size tractors, a set of rare Gibson tractors, hit-and-miss engines, small engines, and horse-drawn equipment. Most pieces have direct ties to farms and homesteads in the Niwot area.

Jerry and Marsha Slepicka have been building the collection since 1989. Many of the tractors run, and the Slepicka family is on hand to share the stories behind each one.

Free and open to the public. Presented by the Niwot Community Association.
