In 1920, there were only 225 tractors in the United States.
Rubber tires for tractors were introduced in 1932.
The John Deere company started out when Deere developed the steel walking plow. It wasn't until they bought a company called Waterloo Gasoline Traction Engine Company in 1918 that they started producing tractors.
In 1930s and 1940s, Williamson County was one of the top three corn producing counties in Texas.
