John Deere 4020

Postby Sd1030 » Fri Aug 17, 2018 8:30 am

Found a 72 model with a loader on it for sale. Tractor has around 5k hrs on and from what im being told its a two onwer tractor mainly used for hay work and bushhogging. My dad grew up on one of these and says it was the best tractor he ever ran. Obviously i know when comparing it to newee tractor technologies have advanced tremendously but for just a tractor to use to move hay around and other odd and farm projects whats yalls thoughts?

They cost more now than they did new. That should be a good indicator of the quality, or it could just be an indicator that baby boomers have a sentimental attachment to them and money to burn. One way or the other, a guy could have made some money on a shed full of them.

I sold mine a few months back. I got seven grand on a very very rough tractor that was out of clutch.
And that's something you should check. How much clutch adjustment is left. Pretty major surgery on the 40s.
Otherwise as bullet proof as they get.

Look at the axles alot have been cracked numerous times and welded over and over. The biggest thing I look for is how it shifts alot of the times they don't shift correctly and you have to try to find the gears i go through all gears to check it can be synchronizer or clutch issues. Thats the biggest things I look for. Typically alot of those with loaders i find the front axle is cracked up because they were carrying haybales or something heavy hitting bumps etc imo the weak part on that tractor is the hitch bracket on them and the axles

I had one for 20 yrs before I updated to get a cab tractor. As others have said easily one of the best tractors ever built but now they belong in the shed painted up as an antique in my opinion. If it`s a powershift be sure and check that the pto will stop after it`s been turned on if it doesn`t that's very expensive to fix. Also the load shaft seals leak sometimes. I would also run it for a while then feel the scv boxes if they feel hot then they`re bypassing on the inside and will need rebuilt. Keep in mind if it`s a syncro range you will loose hydraulics to the loader shortly after the clutch is pushed in which can be a pain depending in what your using it for If just mainly putting out bales you`ll be fine though. The price really varies a lot by condition and also by region. Mine was a powershift and the pto brake was out on it I traded it without the loader and still got $6500 5 yrs ago and was glad to see it gone before spending any major money on it if that helps.

One of the best all around tractors of all time. They are the perfect tractor for hay work in my opinion. The syncro transmission is more durable than the powershift. If you've never run a syncro you will hate it at first but once you figure it out you will like it. One of the smoothest riding tractors out there, they are just balanced really well. I would expect to pay $10,000 for a decent one and I feel like that would be a bargain for what you get

I have wanted a 3020 for a long time. As a kid i always wanted a 4020 and a 1086. Got the ten but have decided i really want a 3020. I don't think it will be much longer.
