Three key inventions that significantly increased agricultural productivity are the mechanical reaper, the cotton gin, and the plow. The mechanical reaper, developed by Cyrus McCormick in the 1830s, allowed farmers to harvest crops more efficiently. The cotton gin, invented by Eli Whitney in 1793, revolutionized cotton processing, making it much faster and boosting cotton production. Additionally, advancements in plow design, particularly the steel plow by JOHN DEERe, enabled deeper tilling of soil, enhancing crop yields.
