About the John Deere 4020
The John Deere 4020 was produced from 1963 to 1972 and is widely considered the most influential American tractor of the 20th century. Powered by a 6-cylinder gasoline, LP, or diesel engine producing between 91 and 96 horsepower, the 4020 introduced the Power Shift transmission and a robust hydraulic system that became the template for modern tractor design. Today it remains one of the most actively restored and farmed vintage tractors in North America. Original service, parts, and operator's manuals are essential for any 4020 owner doing serious work.
