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: -During the 19th century, the technologies that most influenced westward expansion were the telegraph and railroad. Prior to the expansion of the railroad westward, traveling out West was a long and dangerous undertaking. It was also difficult to ship commodities back east for a profit.
Detailed explanation-3: -What is the Steel Plow and What Does it do? The steel plow was used to break up tough soil, bury crop residue, and help control weeds. Due to the rich soil in the Midwest of the United States, wood plows would commonly break.
Detailed explanation-4: -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.
