History and legacy
The source places Rock Island sales by 1912. Related catalog pages give inconsistent 1914 and 1916 acquisition dates, so this history does not select one without stronger evidence. The combined Heider–Rock Island badge survived the ownership transition.

Index power values can include estimates derived from belt or PTO power. They are identified on each model card and are not interchangeable with a measured engine rating. Model years and missing values follow the source index.
