The Most Popular Tractors of All Time

12 of 25

John Deere 4020 (1963-1972)

Here’s the one you’ve been waiting for. The 4020 replaced the 4010, which had a three-year production run.

These machines were not for the occasional farmer, with 95 horsepower and weighing more than 4 tons.

Another thing that separated the 4020 as a big time tractor was its price. At $10,345 new, that would be a $65,000 tractor in 2020.

Considering the size and price, the fact that John Deere sold 184,000 of the 4020 makes it a very significant tractor in the history of farming.

Today, the 4020 remains in service on many farms and has a loyal following of farmers who swear by this classic piece of tractor iron.

  • We added a couple to the list, Martin. Including the Allis Chalmers B and the Farmall F series.

  • Interesting that your Farmall H has widely-spaced front wheels.

    I grew up with one, and it had a tricycle configuration.

  • Glad to see you included the Kubota B series and the Massey Ferguson 35 and 135’s.
    But for me, the list would include the Allis Chalmers CA.
    One of the strongest tractors in it’s class.

  • The Oliver tractor was the first 6 cylinder tractor and also the first tractors to have live PTO’s.

  • The 2N Ford tractor is painted like a 8 N Ford. The 8 N’s were called red bellies because of their paint jobs. The 2 N’s were all gray except the rear rims.

  • Kubota had B5100-B7100 tractors which really were the first subcompact tractors here in the US.

  • The 8000 series Allis Chalmers produced from 1980 to 1985 were well ahead of the competition in their cab design and their power shift trans was the best at the time.

  • Ford 2N. “…switched from battery and alternator…”
    Alternators didn’t appear on tractors for decades later.
    Generator, perhaps?

  • Love my 8N, it’s not a show machine but a work horse. It has a Wagner bucket and a road blade. With forks on the bucket I have have unloaded a refrigerator from a UHaul van, mowed 4 acres, landscaped, moved large rocks, etc.
    It has saved my back and my wallet!

  • I think the 4020 recognition should be upgraded to all of JD’s 20 series.

  • The information on the John Deere “A” is not completely correct. I have a 1949 JD “A” and it has 6 speeds forwards and 1 reverse. There is a high/low arrangement with 1st & 3rd, 2nd & 4th, and then 5th & 6th on the shifter….

  • Farmall F-30.

    5,300lbs 2wd making 30hp and no loader. Those were the days of HEAVY iron.

  • The John Deere 50 Series are all YANMARS painted John Deere green. Most of the JD 50 Series folks know this and love the machines. The US Yanmar models are of the YM Series.

  • There has been several surveys done by agricultural groups , by contacting real farmers not want to bees. By far the John Deere 4020 came in number 1 and the Farmall M # 2

  • In my part of the US the prime workhorse tractors in the 50’s and early ’60 are Caterpillar D4 and D2 steel track crawler tractors.

  • In SouthWestern Ontario, it depended on the Dealer. Massey Harris 33,44, 444 and the Pony, Colt and Mustang were the most popular where I grew up.

  • what about the AllisChalmers wd or wd45/

  • Farmall H and John Deere 720 were and still are solid tractor.
