Minneapolis-Moline had their Ampli-Torc and Magna Power systems, Ford had Select-O-Speed, and Case went with Case-O-Matic. Many of Deere’s competitors had released a transmission that could do this at least to some degree. Deere had been working for some time on a method that would allow the operator to shift between transmission speeds without having to stop, slow down, or even depress the clutch. The engines were a significant improvement, indeed, but the list of improvements in the 4020 didn’t stop there.

This engine was an improvement in both power and economy.

The LP version of the 4020 received an increase in compression to provide over 90 horsepower, an increase of 10. This again was seven more than its forerunner, and suffered the same dip in fuel economy. The 4020 with a gasoline engine was capable of 88 horsepower. 77 horsepower hours per gallon in fuel economy to the 4010. This additional power did come at a cost, though, as the 4020 lost. Now capable of producing over 90 horsepower the 4020 diesel continued to stand ahead of its competition. 125 inches of bore resulted in 24 more cubic inches of displacement and improved the horsepower of the tractor by about seven. When the 4020 diesel was tested in Nebraska in the fall of 1963, the first of these improvements was on display. When the series went through its transformation into the 20 series, these improvements were employed. In the midst of selling over 57,000 model 4010 tractors, Deere’s engineers looked to their suggestion box and found a few ways in which they could improve upon the tractor. And, if those reasons weren’t enough to take the wind out of competitors’ sails, it was introduced so suddenly and unexpectedly that even Deere’s own salespeople needed to catch their breath at its release. It featured horsepower numbers that were head and shoulders above that of the competition. The 4010 included a plethora of innovative features that the rest of the industry either hadn’t even dreamed of yet or were only just experimenting with.

John Deere’s innovative 4010 tractor was easily one of the greatest successes any tractor company had since the industry was created.
