Always appreciate these videos. Informative! Keep it up!

Beautiful 4020! I grew up on a potato farm in northern Maine, I remember when the 4020 diesel came out, that was one monster of a tractor in the 60's.

GREAT INFORMATIVE VIDEO, ENJOYED!! I WRENCHED MY NEIGHBORS 4020 SEVERAL TIME INCLUDING AND COMPLETE ENGINE OVERHAUL, AND LATER A TRANSMISSION OVERHAUL! WAS CURIOUS ABOUT THE 4010 , 4020 DIFFERENCES AS WELL AS THE 30s!! THANKS, GREATLY!! KEEP THEM ROLLING BROTHERS !! 👍👍

Loved the 4010's and 4020's also grew up driving those and some of the big red tractors

I ran a 1971 , J D 4020 When they was new I loved them ,one of the best J D tractor ever made

Looks mighty fine too me. Great job, keep us updated.

I really enjoyed this video. I have a soft spot in my heart for these old tractors. I’ve repainted several 4010s and a 4020. My dad had two 4010s , a 4020 power shift, which was one of my favorite tractors. He also had a 3010 which I still have. I also painted a 4010 for a friend once. As the equipment got bigger so did our tractors. My dad ended up selling all of them except for the 3010, I wouldn’t let him sell that one lol ( I later wished we’d kept the 4020😢). Ours were all propane tractors, I would love to have a 4020 diesel, console tractor, but I really would have no use for one other than to have just to have 😂. These tractors were so easy to work on. We did all our own overhauls and everything. I am wanting to build a shop just for restoring these old tractors, for myself and others. I really liked your 3020 with the factory duals, don’t see too many of those.

Thanks for the great video. Can't wait to see it in action

4020 looks really good as is. Waiting to see when you're done making it in your image 👍🏾

Love those John-Deere tractors. Would rather drive one if those instead of a Cadillac ANY day.

Thanks for the break down in the difference. Now I know what I want for an older tractor.

Great video! Full off some great information! Thanks for posting

Had a '61 4010 row crop...great tractor...

Good video. Always informative!

A little tid bit for you... The old oil bath housing can be converted to a dry filter. It takes a little cutting and welding. The worst part is getting all the screens out. I did one about ten years ago. Looked at a dry one on a 4020, did some measurements and made it work. New were still available at the time, but very cost prohibitive!!! Used must have been gold plated...they were almost as much as new!!! I think I had about a half day into converting it... Most of that was getting and cleaning up. Thanks for the video!!!

Yes, that will look and work great with the duals. I love the 4020. Nice to see some of the differences right there. Interesting fact about the scavenge pump on the syncro stopping with the clutch.

Lots of differences between the 10 series and the 20 series, which made the 4020 one of Deere's all time most popular tractors, as well as cementing the entire 20 series as a huge step forward for Deere's Utility Tractors. "Nothing Runs Like A Deere" 🦌 👍 🇺🇲

Love the 4020. Grew up on one just like it. We had a 2010 and 3020 as well but the power shift was the one we all fought over. We later got a 966 hydro but it never really grew on me like the JD. Thanks for the vid.

Great video! I just inherited a ‘63 4010 industrial. Do you have any videos about the industrials?

grew driving a 4020 what a great tractor.

Great comparison video and very useful. I have a 4010 and your video helps me see areas I needed to know about more. The battery box I have isn't under the seating area and I like your better. Would you send me some info on the box, and how it attaches to the tractor? I tried to figure it out from photos and shop manuals and its hard to picture without pictures.

Some small differences in the front end was the frame was a 2 hole for engine mounting and the 4020 had a 4 bolt...awsome video! I'm in the process of marrying a 4020 rear end with a 4010 front...4010 trans is junk found a good deal on a early 4020 back half

good informative vid nice 4020 would love one myself once had a 5020 to big though. regards UK

Very informative - the equipment focused videos are definitely my favorite. Evidently our 4010 has had a few 20 series upgrades on it such as rocker shaft covers with the tool box. I always wondered why the hydraulics were shaky starting up but they seem to do well once the engine is warm.

I once worked on a dairy farm and did most of my learning on a 4020 gas model.

Your 4020 is very sharp. I also appreciate the straight rust free sheet metal. I like your row crop tractors. I ran a 4020 row crop wide adjustable front axle in 97 98. It was a 1 owner tractor at that time.

Interesting as always

Love the old tractors getting scarce like someone said the new ones are heading to the junkyard who wants to restore one of those.

To whomever is complaining about how the muffler looks, give the guy some time. Takes $$. But I guess not as much on a 1/16 scale or probably 1/64 scale toy that your driving on your knees.Dont throw criticism out unless you can show what your driving.

Looking good 👍 I have a 70 4020 with all the M&W stuff on it

I like your 4020 nice tractor

Great comparison video! I'm pretty knowledgeable on the two-cylinders but never quite understood the differences in the New Generation models. From a distance, they all look the same to me lol. I wouldn't mind having a 4320 or something similar one day. But I really have a soft spot for the 30 and 40 series.

That charge pump explanation was the best I ever heard. Who in the world at JD ever thought that was a good idea I can't understand. I guess the dual PTO clutch prevented the charge pump from being driven all the time. All the brands of tractors of the time had their major flaws though.

I do like the way you put the original parts back on ! You gotta love the style in the new generation tractors, that hood just makes it look like its going fast! Does the 4020 have the aluminium MW oil pan ! I have a 190 or a200 Allis Chalmers muffler on my 2940 with the MW turbo, its less restricted than the JD mufflers . Thanks for sharing that nice tractor

I've spent I bet over a combined 15,000 hours on 4010 diesels and 4020 diesels both sycro and power shift. I have a 1966 4020 diesel of my own. My fuel filters are double spin on canisters with a drain/bleeder. I see yours was switched to the square one. (Stock up on them as I have had trouble finding various filters.) I was curious what the filter next to the generator is for. My block heater is mounted on that mount. I like the M&W cover on the hood. Most of the ones I see are hatchet patch jobs but I think if I were trying to make a clean restoration I'd take the hood to a good fabricator/bodyman and have something welded in so it looked clean. Nice tractors and a nice shop.

Nice video guys. I learned a bunch. My grandpa and now my dad has a gas powered 2510 synchro. A lot of similarities. Loved that tractor. A true multi-purpose row crop tractor. My dad semi-restored it about 10 yrs ago. But he's probably going to retire and sell it in the next couple years. It will be sad to see it go.

The belly PTO was great for running spray pumps Ace Centrifuged pumps

Great video!

Fun fact you could remove the rear steer wheel on John Deere cotton pickers and the front ends of the 4010s and 4020s and swap them out we did that in the fall especially if it was wet helped with cotton harvest

I think the synchro range tractors had a flat floor board, power shift tractors had a hump in the middle. Didn't work well for carrying a water jug between your feet. The power shift was cool, but it would cook my feet in the summer!

@ 2:25, the frame rails are most definitely different on the 4020! They were heavier, and the attaching points at the front of the engine block used 4 bolts instead of just 2 as with the 4010. These changes gave the 4020 considerable more strength for loaders. 4020 frames will fit right on a 4010, but if you try to fit 4010 frames on a 4020, you will weaken the joint at the front of the engine block.

I’m interested in knowing where you got the turbo kit from and also where you get your parts from for the jd 4010.

Thanks for the video. I'm doing auction preview videos and I can't tell the difference between the 4010 and 4020. I'm an International man, but am familiar with the 2 cylinder John Deere tractors. I've never had anything to do with the next generation John Deere tractors.

Nice!

Good video and comparison between the 10 and 20 series tractors. The tractor world was in a state of hyper-evolution in the early to mid 60's and the three heavyweights (JI Case, IH and JD) were going toe to toe. Many old timers will tell you that JD took a step back going from the horizontal two cylinders to the high speed inline six but JD had to keep pace with the 06 and 66 series IH and 30 series Case's of the day. All very interesting history that shaped the face of American (and worldwide) agriculture to what we see it as today.

Thanks for the video lot of good information. My ideal 4020 would be a 72 model powershift 38s on the back. Hope you have a great afternoon lot of cold air coming through from the West.

My son just bought a 1968 4020 and it has the square shaped intake manifold that drops down. It has the wide block like a 4010 but it has pencil injectors. Its also 24 volt with a 24 volt alternator. Would it be original like this? It also has a non adjustable front axle.

Very interested

Sometimes the M&W kit would have the 7 blade fan and the deep aluminum oil pan.

Nice! All of them! I still have the old "66" 3020...syncro, and really miss the 720 My favorite was the D. As a youngster I was too short to work the peddles....and the hand clutch worked for me. 😉 Green has always been my favorite color! 🤠

It will look great with duals

Nice 4020 ..

The 4010 engines sound better than the 4020 in my opinion, and they don't smoke when they idle.

A local farmer brought a 69 4020 and 4520 125 horse power the dealer put a mw on the 4020 the stories goes that it was pulling a 5 bottom plow like the 4520 but it was running off a leaving it the 4020 was pushing over 125

Many hours on a 4020 great tractor

There was a hog farmer near beloit ks that had a 4010, his grinder mixer was 1000 rpm PTO, everything else was 540, usually once or twice a year they would break the pin that shifted the pto speeds

McGrew kity corner of Polk Auction in Paris Indiana. Salvage yard. Also Dennis Polk might be able to help you for hard to find parts as well. Maybe worth a few minutes. Steiner's Tractor Parts Lennon Michigan.

We had a 67 3020 with Synchro Range. Did many hours of loader work until it was replaced in 1982. Never had the hydraulic issue you described.

You're wrong about the hydraulics on a synchro range. Had one for many years on a loader.

Was the front PTO an option or was that standard?

Good looking tractor, however, I can't agree with the hydraulic levers on the console being advantageous. My 71' 4020 has the PTO to the left of the steering wheel and the hydraulic levers to the right of the seat. JUST LIKE the JD 4840 that I drove as a kid with a disc and cultipacker. Long story short John Deere changed the levers and PTO around and carried it on to the newer series tractors. I can't imagine feathering a disc in a wet spot with the lever on the dash. I was taught to spend a good percentage of my time looking back at the implement. That makes the right side lever perfect as you can adjust without actually looking. Long story short I think that mod on the late 4020's was a step in the right direction... FWIW, IMHO, and IME.

Front engine mounts 4010: 3 bolts, 4020: 4 bolts, engine block (drilling) and frame rails different, all other engine parts the same, at first on 4020, except fuel filters were cartridge on 4010 and spin on, on 4020. New style (69+) had basically a completely different engine , only really shared displacement and color. Early 4020 hydraulic system was identical to 4010 except for front drive coupling(interchangeable, most updated, as I don't believe old parts any longer available). The most significant difference is the PTO. The two speed gearing was located in front transmission case and shifted to 540 by no recess in low speed output stub. 1000 RPM was spring engaged, either with no stub, or the 21 splined stub with recess to not contact shift rod, passing through center of shaft. 4020 has two speed gearing added to the rear of trans-diff housing, and had no mid or front PTO. I think that this change was made to accommodate the option of power shift transmission. I have found the weakest part of all the synchro tractors was the clutch, and the PTO clutch coaxial installation in the flywheel, was a poorly planned idea. Many other manufacturers ran a live shaft from the engine to run all the hydraulic pumps, as well as powering the PTO clutch. Another difference is 4010 has pull out fuel shut down, whereas 4020 was either throttle stop override or key switch (electric). New style 4020 all had pencil style injectors, an Bocsh rectangular glass fuel filter. Bottom line, early 4020 had more in common with its older brother than the younger. Fun fact, upright air intake and precleaner was optional on 4010, standard on 4020.

There was an attachment thT didn't go over to well very destructive to the engines it was commonly called A Red Rooster Booster it was an attachment to put either a 20 or 30 lb. Propane tank it would give you extra fuel and power when you hit the switch. Alot of hired hands and kids would over engage it ultimately burning up the engine

Y wld u convert to a dry element over a oil bath?oil bath is less maintenance and does a better job

Seria muy interesante ver los comentarios traducidos al español , 👍

What years did the 4020 come with the the wide fenders and the front wrapr around pieces by the clutch and brake pedals just wondering

Never had a problem with our loader on a 3010 syndrome range.

How do turn it up

We had a 63 4010, a 64 4020, and a 67 4020.... the best one was the 64.. we had an IHC 19FT. 45 Vibra Shank field cultivator the 4020s would run with it the 4010 not so much....

On the syncro tractors with a loader, if you have a hydraulic valve that stays with the loader it works better. You put a t in the pressure line down by the brake pedals and the the return goes to the hydraulic filter housing. You can buy a filter housing from deere with this return line already plumbed or some guys just braze a fitting to the old filter housing. Doing it this way allows all the returning oil from the loader to go back to the front pump without the oil having to be repumped by the transmission pump.

Sprayed a lot of tobacco juice on my cousins 4020 he got upset until I told him if I was getting paid for daylight to dark work I'd feel real bad. Red Man ,4020, dusty fields and free labor its a good deal.

I too, grew up on a 4010 LP, very good tractor. I am also a fan of the 6030. It looked like a 4020 on steriods.

I believe that you are wrong about the 3020 engine being a shortened 404, since the four cylinder 3010/3020 had the balancer shaft to lessen the inherent vibration in the 4 cylinder (270 CID) engine. I wonder how many 48/58 148/158 loaders were installed on these tractors WITHOUT having the reinforcing plates that went on the inside of the frame rails? They are shown in the parts manuals for these loaders.

The farmers back home have a saying, "everyone needs a 4020"

Grew up with, 2010, 3010, then 2940

I have a 4320 needs some head work done runs incredibly smooth but blows a lot of blue smoke due to oil on cold start and has a fuel line leak. But I’m a mechanical idiot so idk

Actually, the biggest difference between any of the “10’s” and “20’s (be it 4020, 3020, etc...) is the redesign of the rear end. My Dad was one of the engineers in Waterloo that was part of the redesign. The 10’s were not holding up in field tests as well so JD “beefed” up the bearings, axels, and gearing in the rear end, transmission, etc. to be stronger....more metal in better places. They are all great tractors, but there is a reason the 10’s were not made long and it was the need for a redesign. Dad was tell you to always go for the “20” series over the “10” series .... but they are all good. The 4020 is still the most popular and revered.....

The screen on the 4010 is called a corn picker screen

Put a chrome or stainless straight Pipe on the 4020! It will sound great! Especially with the turbo!!!

Without watching the rest of the video 1st, is there also a difference with a 4000 vs 4010 or 4020?, years ago I helped on my cousins farm and I used a 4000 diesel alot, with that said, is there much of a difference?.

We never understood why dad's John deere 730 diesel never had fenders we finally realized that fenders were an option and dad didn't buy options

The differences between the 4010 and 4020 are quite subtle...

3010 has the fat injectors as well. I have a 3010 I did a video of. Check it out

I’ve got a 69 4020, nice rigs!! I need to paint mine....enjoy the comparison...

Nice video! One other difference between the 4010 and 4020 is the (Sycro range only) 4010 has 3 reverse speeds and 4020 has two reverse speeds.

How much power is the 4020 turbo putting out

Can you roll start a power shift?

We’re some of the early 4010’s powered by a Cummings engine?

You did not talk about the hydraulics difference between the two

My grandfather bought a 4010 when they first came out for his 1080 acre farm in Florida. I drove it pulling a 5 bottom plow in 5th gear and it ran like a champ. It would run all day long. I miss those days.

Nice tractor. Getting hard to find good looking 4020’s.

Why is your pro lever so short? ?)(4020). They are longer on my 4010 and 4020. Have a good day!

Great comparison of these JD tractor models Curious how the late 60’s early 70’s 4020 compared to the 4000. Was told the 4000 had more Hp, but really couldn’t tell the difference when hooking them both up to same chisel plow. Liked the seat side hyd controls on the 4000 though...

Gorgeous 4020.. I hear the pulling guys like the synchro trans because it stronger and the 4010 rear since its lighter.

My 4010 has grease zerks on front axle that 4020 doesn't have.

Not enough o's in smooth for that one

One of the differences that you didn't mention was the 4020 had a differential lock option and the 4010 didn't....

Engineers keeping their jobs

Yr 2020 traded for a 1963 4010 there is no pressure at the rear hydraulic remotes everything else hydraulic works can anyone help me out?

Looks good now put a straight pipe on it and you will be dealing.
