The John Deere 420 tractor is considered to be a jack of all trades in the industry.
It was produced in many different configurations to suit different jobs.
Configurations included General-Purpose, Hi-Crop, Standard, Utility, Special, and Crawler varieties.
As if that weren’t impressive enough, each configuration has several different wheel configurations.
The 420 was produced from 1956 to 1958 and was equipped with one of three different engines. The 420 replaced the 40 with basically the same styling except for the change in color ( now green AND yellow).
However, some of the earlier models were painted all green so be sure to check the serial plate to be sure. A total of 55,000 of these models were built which sold for $2300 in 1958.
Although most John Deere 420’s have a straight steering shaft, some of the later models have a slanted one.
The engine is oriented in an “inline” fashion with vertical cylinders. Although a two-cylinder, it lacks a belt pulley and flywheel on the side due to this orientation. The Standard and Utility models were available with fixed width front ends.
The “rowcrop” model had a tricycle wheel configuration with either one or two wheels, or it could come with a wide adjustable width front end. There was also a high version known as the “highcrop”.
Perhaps the most unusual of the configurations was the model 420c, which has tracks instead of wheels.
