The global tractor market is estimated to be $137 billion U.S. Dollars in 2022.* While the figures are dated in the next source, they give an indication of how large the number of tractors are in the world. It lists the number of tractors for each of 147 countries as of 2000. The U.S. was  first with 4.8 million followed by Japan with 2.03 million.** We’ll look at applications of Lean and Six Sigma in the tractor industry in India and Brazil and finish with a video of the Massey Ferguson Tractor factory in France.
