John Deere

Cast Steel Plow

• John Deere designed the first cast steel plow that greatly helped the Great Plains farmers. The large plows made for cutting the tough prairie ground were called "grasshopper plows."
• The plow was made of wrought iron and had a steel share that could cut through sticky soil without clogging. By 1855, John Deere's factory was selling over 10,000 steel plows a year.
