I have a 56 and painted them red.  I knew green was the &amp;quot;correct&amp;quot; color, but red looks so much better (IMHO).

However, I dug around and did find some evidence that there might have been some red wheeled 56&#039;s at the end of the production year.  Nobody has been able to prove or disprove that, but its what I&#039;ve been told more than once.  Unless you plan on putting your tractor in a museum, you might as well paint it the way you like it, your the one who has to live with it.
