From time to time, I get an email from a 4020 owner or fan who has a question about the serial number system for the New Generation tractors.Now, I am no expert, but I like playing detective because it’s fun to try and make sense of something I don’t understand or know anything about. And it’s a learning experience that I can take and hopefully use to help someone else.
So strap on your thinking caps and lets see if we can make some sense of this.New Generation Tractors Serial Number Logic (if you can call it that)The serial number of any 10 or 20 series New Generation, Waterloo built, tractor represents more than just a serial number. It indicates the 2000, 3000, 4000, 5000, 6000, 7000 or 8000 series type.It also identifies the chassis type; row crop, standard, high crop, row crop utility, industrial, or other designation. The fuel type; gas, LP, or Diesel, and transmission type; Syncro-Range or Power Shift were also indicated. Last, but not least, the serial number was part of this seemingly complicated sequence. A letter suffix was added to also denote the place of production.The serial number sequence went through some changes, most of them occurring starting with the 1965 production year. Lets start with the system prior to 1965.Prior to 1965, the sequence started with two numbers then a letter.
The first number indicated the Series Production Code followed by the Chassis Production Code. Following the Series and Production Codes, a letter “T” indicated “Basic Tractor”. The remaining digits represented the numbered order of production of the unit which can be used to determine the year of production. It is interesting to note that a third digit (a number) indicating the Fuel Type Production Code (explained further below) was not added until mid-summer 1963 starting with the 1964, 3020 series, production year. See the example at the end of the page for the 4020’s produced prior to 1965.From 1965 on, the sequence started with the letter used as a prefix of “T” which, again indicated “basic tractor”. The letter B would be used to indicate a sub variant such as the 4000 model.

The prefix was followed by the Series Production Code and the Chassis Production Code. The third number indicated the Fuel Type Production Code. The forth digit was a letter that indicated the Transmission Type Production Code. The letter “P” indicated Power Shift and the letter “R” indicated Syncro-Range The remaining digits represented the numbered order of production of the unit which can be used to determine the year of production. The last letter “R” represented the Deere Waterloo Tractor Works.

See the example at the end of the page for the 4020’s starting production in 1965.Here are the codes listed for further reference:The “T” (and “B”) CodeThe “T” code indicated “basic tractor” and was the third digit until the Fuel Type Code was added to the sequence for the 1964, 3020 model year. It became the fourth digit in the sequence until 1965 when it was moved to the prefix indicating the same “basic tractor” designation.Series Production Codes1 = 3010, 3020 (w)2 = 4010, 4020, 4000.

(w)3 = 5010, 5020 (w)4 = 1020, 1520 (d)5 = 2020 (d)6 = 4320 (w)7 = 2510, 2520, 7020 (w)8 = 4520, 4620 (w)9 = 7520 (w)(w) = Waterloo produced tractors(d) = Dubuque produced tractorsNOTE: The serial number system outlined here only applies to the Waterloo tractors. The Dubuque numbering system is different. Check out this link for the Dubuque system if you are interested.

The plate will list the Serial Number, Number of Cylinders, Engine Displacement in Liters or in Cubic Inches, the fuel option, Naturally Aspirated, Turbocharged or Turbo Aftercooled (Intercooled). The plate can also have the country in which the engine was manufactured.There will also be a plate that will list the Engine Option Codes. Each code is a four digit number. The first two numbers of the four digit codes identify a specific group of parts or area of the engine. The other two numbers give a specific option of the parts and their application. If an engine is ordered without a particular component, the last two numbers will be '99'.There also may be Serial Number breaks listed in the parts listings. The P C Industries listing will refer to this as Code or Codes if this is required in the section of components.
Examples of John Deere Serial Numbers and Engine Option Code Plates are listed in the Engine Identification pages.
