I'm not a master painter, so take this FWIW. While we're talking about paint on JD tractors, this is a bit off-topic but somebody might find it useful: I've repainted a few of the 300 series JD tractors and initially thought that maybe these rattle-cans come from the same place. So I tried the cheap stuff. Krylon and Rustoleum both sell a green paint that looks like JD Green. I have used them both. The Krylon is absolute garbage. It goes on very very thin and will not hold a gloss. Rustoleum is much better, but still loses it's gloss once it is dried. The JD Green rattle can green is far superior. I have been able to get some nice glossy finishes with these cans. But be careful not to recoat too soon, or the prior coat will crinkle up, and you'll have to sand it all off. I know that by experience. So I give it one coat, then about 30 minutes later, another coat, and then 30 minutes more another coat. Each of those additional coats goes on while the previous coat is still very very soft.
So spend just a little more and stick with the JD rattle cans.
Also, I didn't see anybody mention that JD has two shades of green: One is called (I think) lawn and turf, and the other is just JD Green. I've always used the JD Lawn and Turf since I was working on either a 318 or a 332.
