Detailed explanation-1: -In 1831, twenty-two-year-old Cyrus McCormick took over his father’s project of designing a mechanical reaper.
Detailed explanation-2: -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-3: -He worked for 28 years on a horse-drawn mechanical reaper to harvest grain, but was never able to reproduce a reliable version. Building on his father’s years of development, Cyrus took up the project aided by Jo Anderson, an enslaved African-American on the McCormick plantation.
Detailed explanation-4: -Cyrus Hall McCormick was born in 1809. He grew up on his family’s 532-acre farm, “Walnut Grove", which was located north of Lexington, Virginia. As a boy, McCormick had a talent for both agriculture and inventing. At the age of 15, he invented a lightweight cradle for carting harvested grain (1824).
