I also have seen a number of green 77 Orchards, but I have never seen a red one. I agree with the red primer, several of the tractors I repair and maintain came with red primer. I strip every tractor that I will repaint down to bare metal, now that I think about it I can&#039;t recall any that didn&#039;t have red primer. I would think that the custom paint would be more popular in the industrial models, construction company colors, etc. But, you never can tell, some large fruit farmer might of wanted his own color. That is just one of the things that makes this hobby so interesting, once you think you have seen everything, done all the correct research, something different happens!!
