Steampunk fans will love this. In the Aug. 1, 2012 local edition of The Budget — a weekly newspaper from Sugarcreek, Ohio, focused on the Amish and Mennonite communities — appears Miller's Monster, a 43,000 pound Case 110 steam engine.
According to the article, the tractor was built in 1912 and is currently owned by J.D. Miller. The tractor celebrated it's 100th anniversary at the recent Doughty Valley Steam Days. Miller spent more than a decade restoring the massive machine, which stands 13 feet tall.
For more on the tractor, see this article from The Bargain Hunter, which details Miller's restoration (and provided the great photo above). There's also a fascinating video on YouTube showing another Case 110 plowing a field.
BTW, I love reading The Budget newspaper, which is published in both a local and national edition. The national edition contains dispatches from Amish and Mennonite communities around the world. For more information on the paper, including how to subscribe, go here.
