John Deere 4020 Tractor Parts

The John Deere 4020 was made from 1964 to 1972. The 4020 quickly gained popularity due to its Syncro-Range and Power Shift transmission and its reliable 6.6L diesel and 5.6L gas (also available as LP) six-cylinder engines. Of the over 184,000 JD 4020 tractors produced the majority were the 6.6L diesel. Available as 2WD and MFWD 4WD (which became available as an option after 1969).
