On February 21, 1865 John Deere (blacksmith) received a patent for plow

On February 21, 1865 John Deere (blacksmith) received a patent for ploughs. He founded Deere & Company in 1837, which still is a major player in agricultural technology. He invented the first commercially successful steel plow.

Deere found that cast-iron plows were not working very well in the tough prairie soil of Illinois. Deere discovered that a plow made out of highly polished steel and a correctly shaped moldboard (the self-scouring steel plow) would be better able to handle the soil conditions of the prairie, especially its sticky clay.
