John Deere Tractor History

Deere & Company, or more commonly known as the brand name John Deere, is an American company with headquarters in Moline, Illinois. It is also the premiere producer of agricultural machinery in the world. The Fortune 500 ranking placed John Deere in the 95th rank.

Agricultural products produced by Deere & Company, typically sold under the John Deere brand, include combine harvesters, tractors, seeders/planters, balers, forestry equipment and ATVs. John Deere products are also found in construction plants, and many gardens feature John Deere string trimmers, ride-on lawn mowers, snow throwers, chainsaws and even for a limited time snowmobiles.

John Deere products are easily identified by their trademark yellow and green color scheme. The company slogan "Nothing Runs like a Deere" is a pun on "Nothing Runs Like a Deer" and is found alongside the Deer logo.

Charles Deere was the original founder of Deere and company and left the corporation to William Butterworth upon his death in 1907. William Butterworth was the president who would expand the company into the tractor industry.

Throughout the 1950s and 60s, the John deere company saw great changes in letters and numbers, from the two-cylinder "Johnny Popper to the bigger 4 and 6 cylinder engines. The company would also go from 2nd to 1st place in the tractor business.

The Lettered Series

At the beginning of the 50's, the catalog of John Deere products was indexed with a letter to indicate their HP. From the lowest to the highest these were the models "B", "M", "A", "G", the grand "D", and the all-new "R".

The oldest and most impressive of the bunch was the "D", which had been adapted from the 1923 Waterloo Boy Tractor. Production of the model "D" continued all the way until 1953 and sold a total of 160,00.

The "D" was the best in the line until the "R" was introduced in 1949 and featured the first diesel engine in a John Deere Tractor. Due to some doubts, as to how the "R" would sell, the company kept the "D" in production until the 1950s.


To address the agricultural need for row crop farming, John Deere had produced the 28 HP Model "A", and 17 HP Models "B" between the 1930s and 1950s. In 1937, the more powerful Model "G" was added to the line of row crop tractors. In 1947, the "M", with an all-new hydraulic mechanism was introduced.

The Numbered Series

By 1952, the last of the wartime restrictions had been lifted and the tractor industry became a heavy competition between powerful and innovative manufacturers. John Deere decided this would be a good time to abandon the confusing letter system and use and easy to understand number system to inculcate the ever more powerful tractors they were producing.

The model "40" was the first of the line and features 23 HP on the drawbar. Soon after came to the 28 HP "50", the 37 HP "60", the 45 HP "70" and then in 1955 the 62 HP "80" was released as the very first 5-Plow tractor from the John Deere Company.

The 20 Series

John Deere introduced the "20" series in the 1950s, these featured more HP and more yellow on the color scheme than we see now. The first of the 20 series were the "320" that could be considered the bottom line for any serious farmer and the HP was never properly measured. The "420" was the next up and had 21 HP. Then there was the 26 HP "520", the 35 HP "620" and 51 HP "720". But it was the "820" that broke a record with a 70 HP. Prices for these units ranged from $1,885 for the small "320" and $4,850 for the monstrous "820".

The 30 Series and the Last of the Johnny Poppers

Throughout their history, the John Deere Company had produced two cylinder engines with a specific cadence to their mechanical function. The engines were simple yet capable of remarkable power. While they didn't know this at the time, buyers in the 50's were buying the very last two cylinder engines. This series featured upgraded power and special components for easier use and comfort while working. In the 30 series, we saw the 22 HP "330", the 28 HP "430", the 35 HP "530", the 44 HP "630" and the 54 HP "730". The "830" had the same 70 HP as the "820".

The Next Generation of Power

Toward the end of 1959, the John Deere shocked the world with the production of the super powerful "8010". The "8010" featured a powerful 6-cylinder engine that was purchased from the General Motors Company. The "8010" was capable of a full 150 HP at the drawbar and the capacity to haul 8 plows at 7 MPH.

That was three times the cylinders found in any other tractor produced and had over twice the horsepower as well. The price was also especially high, at $30,000 the "8010" was more than 5 times as expensive as any other previous model. The price was the reason that only 100 of the "8010" and "8020" line were sold. But this was the beginning of a new age of power for John Deere.

In the 1960's, John Deere celebrated the start of the decade with a new series, all with four to six-cylinder engines. We saw the 39 HP "2010" and the "4010" that had 72 HP as the first to come out of the line. In 1961 the 51 HP "3010" was being sold alongside the 30 HP "1010". All these models were sold at the same attractive prices as their predecessors and were very popular because of it.

For example, at the lower end of the price range was the old model "330" and the new model "1010" which would both cost about $2,200. But the HP went up a full 8 HP for the same price. All the models made during this time had four-cylinder engines, except for the "4010" which had a six. Nevertheless, the 72 HP engine was not enough for the farmers out west, so in 1963, John Deere added the "5010" to the line. It had a 100 HP engine to compare to the monster "8020's" 150 HP, but only cost $10,730, less than a third of the cost of the "8020".

The "020" series

By the middle of the decade, John Deere was updating their entire line of agricultural products with special powers and features. This new series was the one that would take them into the next decade. The series featured the Model "1020" which had 32 HP, then there was the 44 HP "2020", and the 55 HP "3020". Then the "4020" had 75 or 83 HP depending on the model. The "5020" had an impressive 114 to 122 HP.

Across all the makes and models, the John Deere Tractors were built to very specific standards and for various locations. For instance, any of them could be fitted to work within orchards by adding special fenders. Rice paddies could be worked with the addition of wider tires. Then farmers that needed greater clearance could purchase a tractor that appeared to be on stilts. Then most models, especially the earlier ones, could run off distillates, kerosene, diesel and gasoline fuels.

This was also the age when John Deere moved their operations internationally and opened up plants for fabrication in various locations of the globe.

Following are some of the more notable models to come out of the John Deere Company that fans of these powerful machines will love:

The 40 Series

Between the 70's and 80's, John Deere invested over $1Billion to invested in improving their facilities and also introduced a new line of implements. Arguably the most popular of the 40's was the "2040" capable of a full 70 HP from a diesel-powered engine.

Then the 8000 series were an all new line of reinvented tractors rebuilt from the ground up to include a variety of features and additions to fit the needs of farmers all over the world.
