John Deere 420

Last Updated: June 2024

Overview

The John Deere 420 is a classic row-crop tractor produced by John Deere between 1956 and 1958 in Dubuque, Iowa. This tractor was designed to be versatile, offering different engine types for various fuel preferences: gasoline, all-fuel, and LP-gas, each with 1.9 L, two-cylinder, and liquid-cooled features. The 4x2 2WD chassis is paired with a manual steering system and an unsynchronized gear transmission system that offers up to 5 forward gears and a single reverse gear. The open operator station and varied PTO options exemplify the tractor's utility for a range of agricultural tasks. Despite its age, many 420 models are still in use today, thanks to their sturdy build and ease of maintenance.
