So my brother-in law sent me a picture the other day of a compressor that he was installing on a John Deere planter, I had to go see the thing in person. I'm fairly sure it's a Viair 450-60-80, here's the pics. Also anybody seen the new portable Slime compressors, they really look like a smaller Viair.
I definately like the air filter on this better than what they're turning loose from Viair, it's actually a K&N on the inside of the metal shield. And aparently these compressor setups or just the compressor thru John Deere is $600, must be the special green paint lol!
