Analysis
In 1916, Deere and co. (present day John Deere) purchased
the Waterloo Gasoline Engine Works in Waterloo Iowa. This is the event that
brought John Deere into the production of tractors. In 1923, their former
tractor, the Waterloo Boy, was replaced by the John Deere model D, the first
tractor to wear the John Deere name. Many other models of tractors were
introduced through the 1920’s and 30’s including the model A and B. Production
of these so called lettered series tractors lasted until 1952, when the company
introduced the first of the numbered series, the models 50 and 60. The models
40, 70 and 80 would soon follow. In 1956, production of the 20 series began.
These were replacements of the numbered series and tractors were similar in
design, although some improvements were made. The 30 series was introduced late
in 1958. These replaced the 20 series tractors and were again similarly
mechanically designed with slight changes in appearance. All John Deere
tractors to this time had ran on two cylinder engines, most gasoline, but a few
had diesel engine options. None exceeded seventy five horse power. The main
opinions of farmers were that you either loved these two cylinder tractors or
you hated them. The New generation
tractors were introduced in 1960, which included the models 3010 and 4010.
The
John Deere model 4020 (1963-1972) is the best tractor ever made, in the history
of farming. It provided advanced features and unsurpassed power that
competitors had never dreamed of or began engineering of yet. Some features
took competitors up to twenty years to catch. The 4020 was the best-selling
tractor of the era and was the most popular tractor in history. Virtually every
farmer, no matter the equipment they may use, knows about the John Deere 4020.
An article in the green magazine, 4010 + upgrades = JD
4020, by Benjamin Hain, points out key points in explaining the significance in
the John Deere 4010 and 4020 tractors. Hain first states; “John Deere’s innovative
4010 tractor was easily one of the greatest successes any tractor company had
since the industry was created. The 4010 had a plethora of innovative features
that the rest of the industry hadn’t even dreamed of yet or were only
experimenting with” (Hain). This shows the significance of the 4010 in its
competition. It was a step or two ahead of its competitors, which include
Farmall and Oliver, as well as Allis Chalmers. “If that wasn’t enough to take
the wind out of the competitors sails, it was introduced so suddenly and
unexpectedly that even Deere’s own salespeople needed to catch their breath at
its release” (Hain). The model 4010 was introduced very quickly with very
little warning. This helped insure that the competitors had no way to compete with
the 4010 at its release. The 4010 was a very popular tractor and sales sky
rocketed, but nothing is perfect. Some of the customers who had purchased the
John Deere model 4010 tractor had wrote letters to the John Deere engineers
with some suggested improvements. The engineers used these suggestions to
design an improved tractor. These improved tractors made up the next series of
the New Generation classification; the 20 series, and includes the John Deere
model 4020. “When the 4020 diesel was tested in Nebraska in the fall of 1963,
the first of these improvements was on display. Giving the engine an additional
.125 inches of bore resulted in 24 more cubic inches of displacement and
improved the horsepower of the tractor by about seven” (Hain). Horsepower has
always been a big deal in farming. Tractors need horsepower, and most
importantly, they need to be able to get the horsepower to the ground. Any
spinning is a loss of horsepower and any internal components that rub or touch
in a machine are a loss of horsepower. The John Deere engineers incorporated
this in the fact that the engine is mounted directly on the transmission, while
the other manufacturers, like Farmall, had a separate gear box called a torque
amplifier, between the engine and transmission on they’re farm tractors, which
resulted in a loss of engine horsepower making it to the ground. “Now capable
of producing more than 90 horsepower, the 4020 diesel continued to stand ahead
of its competition” (Hain). The John Deere model 4020 was yet another step
ahead of the competition from the competitors. It had unseen horsepower
ratings, and was also introduced quickly, only three years after the 4010. One
of the major improvements and advanced features of the model 4020 was the new
Power Shift transmission. Up until that time, while operating a tractor, you
would just have to pick the right gear and stay in it. If the soil began to
make the tractor pull hard or bog down excessively, you would have to stop and
change to a lower gear. Some of John Deere’s competitors had simple sorts of
solutions to these problems, which were known as torque amplifiers.
“Minneapolis-Moline had its ampli-torc and Magna Power systems, Ford had
Select-O-Speed and Case had Case-o-Matic” (Hain). These were not like a Power
Shift transmission, but a separate gear box on the transmission that would
tighten up and slow the tractor down while in tough conditions. “Deere never
produced this system commercially, as it believed (and sold tractors under this
premise) that “Torque Amplifiers” of that kind were no more than “Torque
Substitutes” and that a good tractor should be able of getting work done
without resorting to such workarounds” (Hain). This statement from Hain
expresses John Deere’s feelings on the production of Torque Amplifiers and the
reason that the company chose to create an entirely new concept of
transmission. The new Transmission was not at all a workaround. The operator
could actually shift between gears while moving, and there was only one lever
needed to do so. This was a huge advantage for farmers who may have hard clay
soils in their fields. The Power Shift transmission is very common among the
new tractors of today. You will probably not be able to find a farm tractor that
is brand new with-out a Power Shift transmission. The 4020 also had a float
ride and adjustable seat, which was designed with the help of chiropractors, to
offer the best seating positions. These were called Personal Posture seats, and
were the first to be introduced among the farming industry. These are also very
common today. The 4020 was also the first to offer roll over protection and
axel mounted dual rear wheels, along with Manufactured Front Wheel Drive/ Front
Wheel Assist, which is known in the automotive industry as four wheel drive.
The John Deere 4020 was the tractor that started the modern tractor industry.
It began the many advanced features of today and was a few steps ahead of the
competition. The 4020 is a classic today, but yet still has many of the modern
features, making the John Deere model 4020 the best tractor ever made.
