1. John Deere 3020 tractor history

The John Deere 3020 tractor was manufactured as a part of the New Generation Series from 1964 to 1972. The first Series was produced from 1964 to 1968, and the second from 1969 to 1972. The tractor series was made in Waterloo, Iowa, and Mexico. The total number of tractors produced was 74,463.

The model replaced the John Deere 3010 tractor, although the two machines were similar. However, the John Deere 3020 tractor stands out in the New Generation Series due to improved hydraulic levers, a longer, bent gear shift lever, and a narrower oval muffler, providing better visibility.

The original price for the New Generation Series from 1964 to 1972 was $10,000. Nowadays, the price ranges up to $17,000 at local auctions and dealers.

In addition, throughout the years, the serial numbers were changing, including:

  • 1964: 50000
  • 1965: 68000
  • 1966: 84000
  • 1967: 97286
  • 1968: 112933
  • 1969: 123000
  • 1970: 129897
  • 1971: 150000
  • 1972: 154197

However, the numbers changed with the years & it might be challenging to read them correctly. For instance, if your serial number is T113R074121, here is the guide to read it:

  • The first “T” means tractor, and 1XX means your tractor is 3020
  • The second number x1x tells if it is 1 – row crop, 2 – standard, 3 – high crop
  • The third number xx3 is fuel designation, 1 – gas, 2 – LP, 3 – diesel
  • The letter R is for synchro transmission, while P is a power shift transmission.
  • T113R is a 3020-row crop, diesel engine and synchro transmission.
