An early threshing machine, patented in 1837 by Hiram A. and John A. Pitts of Winthrop, Maine, U.S., was operated by horsepower.

When was the first threshing machine made?

Their timing coincided with the development of the threshing machine, designed to remove a plant's grain from its stalks and husks, thus “separating the wheat from the chaff.” The first threshing machines were invented in Great Britain in the 1780s and American-made machines soon followed.

Why was the threshing machine invented?

The thrashing machine, or, in modern spelling, threshing machine (or simply thresher), was first invented by Scottish mechanical engineer Andrew Meikle for use in agriculture. It was devised (c. 1786) for the separation of grain from stalks and husks.
