A Tradition Rooted in Wisconsin’s Heartland
Welcome to the Union Thresheree
Held every July in Symco, Wisconsin, the Union Thresheree is a celebration of agricultural history and community spirit. Each year, we come together to preserve our agricultural and homesteading heritage and celebrate the technologies of yesteryear. From antique tractors and steam engines to live music, food, and family fun, it’s a weekend where the past comes roaring back to life.

What is Thresheree?
Located at the center of Waupaca County, the Union Thresheree Grounds in Symco, Wisconsin, have been part of the Larry Werth family for over 70 years. What began as a gathering of local farmers has grown into a multi-day celebration of vintage machinery, agricultural history, and community spirit.
Every year, thousands of visitors walk these 33 acres to experience the smell of fresh-cut hay, the hum of antique engines, and the camaraderie that keeps this tradition alive.
MORE THAN JUST A WEEKEND
Symco Hotrod & Kustom Weekender
Every second weekend in August, the quiet town of Symco comes roaring to life. The Symco Hot Rods & Kustom Weekender takes over the Union Thresheree Grounds with classic cars, vintage campers, and a whole lot of old-school charm.
Hot rods and kustoms from across the Midwest roll in with Shasta and Scottie campers in tow, packed with vintage gear and memories waiting to be made. Add in live rockabilly music, great food, and the unmistakable spirit of small-town Wisconsin, and you’ve got one unforgettable weekend.
