They were painted both ways. Green for ag, yellow for industrial. No real difference when it comes to the machine. Usually owners repaint them, but sometimes, they yanked bits across the factory and repainted on the fly.
For example, my 420c is green all the way, except the reverser which is yellow under green. I know it was ordered Ag because my uncle sold it new, then got it back 10 years later.
So, now you get to check all your main castings to see if they are green under yellow or not.
Oh, and the track frames were all yellow, as were the sprockets and idlers. So don't bother looking there.
