The Old Threshers story is unequaled in its growth in nearly 4 decades of existance. From the thoughts and wishes of an interested farmer, the annual Old Threshers day has evolved from a small neighborly demonstration to a spectacular three day event bringing over 5,000 people annually from many states and foreign countries to the show. With over 130 exhibitors from many states, it is one of the most unique events in the midwest United States with many one of a kind antique threshing units and steam engines in actual operation, over 15 draft horse teams working horsepower units providing a rare opportunity to show the early birth and evolution of our agricultural technology. Many displays and demonstrations have been added to the show each year to attract and entertain all ages.

The 1990's proved to be some of the most progressive years for this group. They received federal status as a 501(C)(3) non-profit organization and purchased over 7 acres of land as a site for the show. Along with the visibility and permanence of the show and the stability of the group that this commitment provides, it has also provided the opportunity to expand the show with historic buildings, displays, attractions and events. Twelve buildings have been moved in and are preserved, bringing back Main Street of the past with sights and sounds of yesterday. A kitchen/concession building with modern restrooms was built through donations, fund-raisers and volunteer labor in 1997. Thousands of hours of volunteer work have been spent restoring as well as equipping these buildings with actual working demonstrations and memorabilia. The show has grown by thousands in attendance each year. The show was proud to host the J.I.Case exposition in 1999.
