John Deere 4020 tractor was a power equipment model produced in the span of 1964 to 1972 by John Deere Company. This agricultural tractor was launched as a replacement of the 4010 model, which launched in 1960 as a part of Deere’s New Generation series. There are plenty of upgrades brought by the 4020 including higher horsepower, differential lock, and more heavy-duty axles.
This tractor was offered in diesel, LPG, or petrol engine. The standard version of the John Deere 4020 tractor came with a syncro-range transmission that had 8 F and 2 R gears. Meanwhile, there’s also an option power shift transmission. Other optional features provided by the company were enclosed cab with air and heat conditioning as well as dual rear wheel alternative.
The production of the John Deere 4020 tractor was led by the sale number of the 4010 that passed the mark of 40,000 units from 1960 to 1962. Being a best-selling release, the design was inevitably passed to the new model, that’s able to replicate the success. In fact, the model’s overall design was a prominent reason why the 4020 was so successful.
There were more than 184,000 units of John Deere 4020 tractor produced, which speaks for its massive popularity during its time. There are several small adjustments made over the production years for this and other models under New Generation series, such as visibility improvement by integrating slimmer oval muffler, relocating the hydraulic lever to the operator’s right side from the dash’s left side, and using bent-shaped and longer gear shifter.
The company launched a 4020-inspired tractor, the 4000, in 1969. This unit was marketed as the more economic version of its predecessor. It was nearly 1,000 lbs lighter in frame while maintaining the powerful aspect, but at fewer prices. That being said, there were only almost 8,000 units of the 4000 sold – a significantly smaller number than the 4020.
