John Deere settled in Grand Detour, Illinois. At the time, Deere had no difficulty finding work due to a lack of blacksmiths working in the area. Deere found that cast-iron plows were not working very well in the tough prairie soil of Illinois and remembered the needles he had previously polished by running them through sand as he grew up in his father's tailor shop in Rutland, Vermont. Deere came to the conclusion 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.
