ANNUAL FARM HERITAGE DAYS
THE MAIN EVENT
Our biggest event at the Warren CO‑MO Old Threshers is our annual Farm Heritage Days, now expanded into a full three‑day celebration. This show represents the culmination of countless hours of hard work from our members and volunteers, all coming together to display, demonstrate, and preserve the tools and techniques of farm life from an era long past.
Some of our largest attractions are our threshing machines, powered throughout the weekend by both steam traction engines and gasoline tractors. Another crowd favorite is our belt‑driven sawmill, operated by either a steam traction engine or one of our larger gasoline tractors. We’ve also added corn shelling demonstrations, giving visitors another hands‑on look at historic farm practices.
The grounds stay lively all weekend with tasty BBQ, live music on Saturday and Sunday, and activities for the whole family. In 2012 we introduced an antique tractor pull, followed by a garden tractor pull in 2013. In 2025, an Out‑of‑Field Tractor Pull joined the lineup on Saturday evening. As always, we continue to feature our antique tractor show, parade of power, and a variety of vendors offering crafts, goods, and novelties made the old‑fashioned way.
Adult Games
We offer a variety of games and activities at our Farm Heritage Days one of which being the "Barrel Train" pictured to the right. We even have 2 adult sized pedal tractors for our Adult Pedal Tractor Pull which offers cash prizes to our winners.
Kids Games
Our kids games are not only fun for the little ones but mom and dad will get a laugh just watching. Best of all entrance to our Farm Heratige Days is still free and so is entering the kids into our games. We couldn't have these events without including the pedal tractor pull - it is a favorite of all the younguns'. We also have a nickel hunt in the straw stack from our threshing machines, a hoop race, sack race, egg in spoon race and plenty of other interactive displays to keep the kids busy all day.
Tractor Games
One of the very entertaining things to participate in or just watch are our tractor games. Tractor owners or drivers can participate. Games include the slow race, gathering the chain, the ball drop, and even a blind driving event. Its fun for both participants as well as spectators
Vendors and Demonstrators
Every year a big part of our show are the vendors that come and offer thier goods. We have a great history of having a jams and jellies vendor, wooden kitchen utensil maker, broom makers and many others. Outside of the museum building you may even find a blacksmith or a chainsaw carver.
If you are a vendor interested in participating in the Farm Heratige Days please take a moment to visit our contact page and send us a note. Vendor set up is currently free and building interior space is limited but available on a first come first filled per request basis.
