About us

Midwest Old Settlers and Threshers Association (MOSTA) was founded in 1950. The original idea to form Midwest Old Threshers Association, a non-profit organization, came from a discussion between Clark Everts, W.E. (Ted) Detrick, Ray H. Ernst and Herman E. Elgar in September 1949. The four were returning from the Zehr Threshing Reunion in Pontiac, Illinois. Considering the many Steam Engines and Separators in Henry County, Iowa, the men decided there was a great potential to host a Threshing Reunion in Mt. Pleasant, Iowa.
