I like to watch one lonely farmer on you tube. In the last couple of days he has put up a few videos on a JD 60 that seems to have been painted some shade of yellow in its life. He believes it is a John Deere made and painted for Caterpiller. I know some Deere dealers were allowed to sell both Deere and Caterpiller. I believe this was more common out in the Western US. I was under the impression that they were allowed to sell both brands but was not aware that Deere painted and decaled in Caterpiller colors.
My opinion is the tractor may be a industrial 60, but was not painted and decaled in Caterpiller colors from the factory. What do you think?
