Celebrating 75 Years of Midwest Old Threshers

The Midwest Old Settlers and Threshers Association (MOSTA) was founded in 1950, marking the beginning of a cherished tradition rooted in agricultural heritage and community spirit. The idea to create a non-profit organization dedicated to preserving and celebrating the legacy of threshing originated in September 1949. Clark Everts, W.E. (Ted) Detrick, Ray H. Ernst, and Herman E. Elgar, inspired by their visit to the Zehr Threshing Reunion in Pontiac, Illinois, envisioned a similar event in Mt. Pleasant, Iowa. With an abundance of steam engines and separators in Henry County, the potential for a local reunion was undeniable.

Through a series of winter meetings, the election of a Board of Directors, and dedicated planning, the Midwest Old Threshers Association was officially chartered on August 21, 1950. Less than a month later, on September 20–21, 1950, the first Old Threshers Reunion came to life. The inaugural event featured 15 steam engines, 8 separators, and drew an impressive crowd of approximately 10,000 attendees.

Over the years, the Reunion has grown into a nationally recognized celebration of agricultural history and vintage machinery. Today, the event attracts over 35,000 hard ticket sales annually, showcasing over 2,000 exhibits and attractions, from steam engines and gas-powered tractors to live demonstrations and historical reenactments. Midwest Old Threshers continues to honor its founders’ vision by bringing people together to experience the rich heritage of rural America.

As we celebrate 75 years of this beloved tradition, we invite you to join us in Mt. Pleasant, Iowa, where history comes to life and community thrives.
