John sold his first plow to a farmer named Lewis Crandall. Lewis loved the plow told lots of other farmers. By 1841, John was making 100 of the plows every year. In 1843, he started working with another man named Leonard Andrus to help him keep up! By 1848, John had stopped working with Leonard and moved the business to Moline, Illinois. Moline had water power, coal and cheaper transportation than in Grand Detour. In 1850, John’s company made 1600 plows. The company was soon producing other tools to go with the steel plow.
