Advance Rumely Ideal Separator, 32 x 52

Advance Rumely Ideal Separator, 32 x 52

Usage conditions apply
Ronald Miller of Geneseo, Illinois, donated this threshing machine to the Museum in 1988. The bright red paint that covered the machine when new had faded, but wood and internal parts were in excellent shape, a testament to the care that farmers lavish upon their machines.
Smithsonian conservators decided to accept the threshing machine without restoration, and this separator threshed oats at the 1991 Smithsonian Folk Festival, pulled by a Rumely Oil Pull 20-40 tractor.
The 32 x 52 designation refers to a 32-inch cylinder and the 52-inch-wide threshing shoe. The 7-ton machine was designed to have four men pitching bundles of grain into the feeder; it could thresh over 2,500 bushels a day.

"I ran across the original mailing flyer advertising the Advance Rumely Ideal Separator (Threshing machine) showing a picture of both the 32-52 as well as the 20-40 Oil Pull Tractor that the company offered to its customers. The text reads, "Right now every kernel counts...On whatever basis you put it, high grain prices or patriotic duty... " So my question is; was the text in reference to WWI ? I would be interested to know the relationship between agricultural advertising and the Great War or whether there were sentiments similar to this. Thanks! "
