That's Florian C. Karl at the controls of the 16 HP Advance engine. He has operated it for several years for Ermin Morrell.
We see Marvin Boettcher and his 30-60 Aultman and Taylor tractor at Scott-Carver in 1973.
This old time Fordson tractor belongs to Stanley Falada, Route 1, Mabel, Minnesota. He brought it to the Hesper-Mabel Steam Threshing Days in 1973. Courtesy of John Hays, 1511 Iglehart, St. Paul, Minnesota 55104
