That is what these guys with these new tractors don't understand. That 4020 is raw rugged tractor and still going 40+ years later. The iron, axles, gears, the tractr in general is hard to beat. You had to be doing something half stupid to tear one up. These new tractors are a basket full of problems waiting to happen. You got guys with power train problems, transmission problems, axle amd differential problems, guys breaking loader arms, electronic whizzos screwing up etc. We never had these problems years ago, stuff like that was unheard of. Yeah, maybe an alternator, or a starter, or a water pump or something like that. These new tractors are having catastrophic failure and half the time only have 1000 or 1500 hours. I got a buddy who runs a tractor repair shop. He says the new jd have computerized stuff similiar to cars. He said jd is claiming copyright propriety and if you can't get into the diagnostics, you can't repair the tractor. Jd is apparrently trying to run a mafia style shakedown in a sense. The made the tractor and they are the only one that can fix it. We are trying to push through a "right to repair law" in which jd would have to furnish the diagnostic information. Until then, who want to buy a tractor you cant work on. These new tractors seem like a real mess to me and most will probably be long gone and sitting in the junk yard way before 30, 40, or 50 years of service. I've upset some apple carts on here, but i sure like to talk to these guys when their little foreign made tractor hit 10,000 hours if it will stay running that long.
