Prior to the Steel (or iron) Plow, plows were made of wood. If you hit a buried rock, or even a large root, you could break the plow's blade.
Thomas Jefferson was the first to work out the exact proper angle of the mouldboard of a plow, (the curved part of the plow that turns the soil)
Charles Newbold acquired a patent in 1797 for the first cast iron plow. David Peacock followed in 1807 with a couple similar designs that resulted in a successful patent infringement suit by Newbold against him.
Blacksmith Jethro Wood acquired patents for two (three-part) cast iron plows in 1814 and 1819 that revolutionized the industry, making interchangeable parts a reality.
The first self-polishing steel plow, the Grasshopper Plow, was invented by JOHN DEERe in 1837. This made tilling prairie land finally possible.
