Detailed explanation-1: -The mechanical reaper invented by Cyrus McCormick in 1831, the mechanical thresher designed by Hiram and John Pitts in the 1830s, and the steel plow developed by John Deere in 1837 revolutionized farming. These inventions allowed farmers to produce more crops at a lower cost for a rapidly expanding commercial market.
Detailed explanation-2: -Cyrus Hall McCormick invented the mechanical reaper, which combined all the steps that earlier harvesting machines had performed separately. His time-saving invention allowed farmers to more than double their crop size and spurred innovations in farm machinery.
Detailed explanation-3: -In 1831 Cyrus, aged 22, tried his hand at building a reaper. Resembling a two-wheeled, horse-drawn chariot, the machine consisted of a vibrating cutting blade, a reel to bring the grain within its reach, and a platform to receive the falling grain.
Detailed explanation-4: -The impact of McCormick’s reaper was profound. Crops could be cut far faster than before, and with fewer farm hands to pay. By some estimates, about 75% of the U.S. labor force was connected to agriculture in 1820; by 1968, that number had dropped to just 5%.
