The Sageng Thresher eliminated many problems faced by conventional steam threshing rigs

The working model of the Sageng thresher in 1/3 scale when it was shown at the 1998 Rollag, Minn., Steam Threshers Reunion.
A working model of one of the Sageng threshers about 1910, giving a sense of how huge the Sageng was. Doubtless two of the people in the picture are Halvor Sageng and his brother, Ole (a Minnesota state senator), but it's unclear which ones. The others are probably investors.

The blueprint of the Sageng thresher that got Alfred Steidl interested in making a model of the unique machine. No full-size Sagengs are known to exist.
