"The portable horse-powered treadmill invented in 1830 by Hiram and John Pitts of Winthrop, Maine, was coupled with a thresher, or "separator."A list of incorporation dates for U.S. firms producing steam traction engines is here. But in the U.S. grain belt, due to the roughness of rural roads, the scarcity and expense of delivering coal to power steam engines beyond the railroad lines, and the availability of inexpensive horses, the predominant form of the threshing machine through the 19th century remained the stationary, horse powered version. Only with the invention of liquid petroleum fuels in the early 20th century, and subsequently the internal combustion engines that ran on petroleum fuels, did the horse powered equipment fade away. It was certainly well after WWI that horse powered threshing crews ceased to roam the American Midwest, replaced by mechanical crews. The reason the stationary thresher crews needed so many hands, was that they were cutting wheat in the field, tying sheaves, and bringing the sheaves to the threshing machine. Once the internal combustion engine was available, it made sense to mechanize the whole process, and add cutters and conveyors, along the lines originally laid out by the earliest steam powered "combine harvesters" of the mid-19th century..
The horse-powered treadmill was later replaced by the traction engine tractor, which both transported the threshing machine from farm to farm, and when a destination was reached powered the thresher."
Not a woman in the county but hates the threshing machine. The dust, the din, the sustained exertion demanded to keep up with the steam tyrant, are distasteful to all women but the coarsest. I am not sure whether, at the present time, women are employed to feed the machine, but some years ago a woman had frequently to stand just above the whizzing wire drum, and feed from morning to night...posted by Abiezer at 4:09 AM on August 26, 2009
Steam engines don't work very well for small mobile applications. I have no doubt you've seen pictures of them, but I wonder if those were advertising pictures from the manufacturers?
