This photo, taken in 1951 on the Grenfell ranch in South Dakota (but not on a Sunday), shows Barbara Grenfell on horseback, Harold Currey (1902-1971) on the threshing machine* being pulled by the McCormick-Deering 22-36 tractor driven by William Grenfell (1879-1956).
[From my personal collection]
Although the tractor looks practically prehistoric, a note on the cardboard Kodachrome slide holder credits it with "25 crops on ranch," so Grandpa Grenfell must have acquired it in 1926.**
The two men in the picture below are Grandpa Grenfell and his youngest child, Richard (1904-1981), who was Barbara's father.

I was able to find a video of a slightly newer McCormick-Deering 22-36 in action.

*This looks like it was originally designed to be pulled by a team of horses which would be in keeping with Grandpa Grenfell's well-known resistance to change. (Dad said that the some of the metal lugs on the rear wheels had gotten lost over the years leaving big gaps which caused the tractor to lurch along so he repositioned enough of them to smooth out the ride and got no thanks for his efforts.)
