Looking to trade a 1975 JD 4430 and a 1967 3020 with loader on a newer 4x4 cab tractor with loader. I am a John Deere fan but am not wild about the newer models. Am considering JD and other brands, even Mahindra. What I'd really like to find is a low hour John Deere 7220. They were built in the US and have no emission control systems. Plus, they are 6 cylinder. They are hard to find and are expensive. Any and all info appreciated but practical experience trumps hearsay. Thanks.
