Approximate Chronology 
of Production Diesel-Powered Farm Tractors

I compiled most of this list by reviewing the book Farm Tractors 1926-1956, from Intertec, which was in turn compiled from advertisements in Implement & Tractor (I&T) publications.  The book says that the advertising dates weren't always the same as the introduction dates, and so any given date may be off by a few years.  See any mistakes?  Please e-mail me at
  1932:  Cat Diesel 68-79 crawler (first production diesel tractor, wheeled or crawler)
