John Deere 4020 Oil Filter Cross Reference Info

The John Deere 4020 is one of John Deere’s all-time most popular tractors, and is still highly regarded as a workhorse around the farm. Manufactured from 1964 to 1972, a staggering (especially for the time) 184,000 4020’s were built. What is even more impressive is the thousands and thousands of these 4020’s still running like the day they left the factory. This article will (hopefully) provide you with the John Deere 4020 oil filter cross reference information you need to save some time and money on filters.

John Deere 4020 Oil Filter Cross Reference

There were several engine options available on the 4020 but fortunately they all used basically the same filters. There are many filters for 4020’s that will cross reference to the OEM John Deere filters, but the ones we list are easy to find and affordable. Since the filters for this tractor are so affordable it’s a good idea to keep several on hand. That 50+ year old machine just might make 50 more with timely oil and filter changes. Let’s get into the John Deere 4020 oil filter cross reference info:

John Deere 4020’s manufactured between 1963 and 1968 hold 8 quarts of 15W40 oil. Starting in 1969 (after serial number 200001) the oil pan was redesigned to hold 12 quarts. The standard John Deere 15w40 oil you can get from the dealership is pretty good, but pricey. Shell Rotella T5 Synthetic Blend performs just as well or better than the John Deere oil, and it is easier to find and more affordable. In newer engines we normally recommend using Royal Purple oil, but I think ultra premium oils are a bit of overkill in a 4020. Here is a link to a 3 pack of gallon jugs of Rotella T5, which is enough for a change on both the 8qt and 12qt 4020 engines: Shell Rotella T5 Synthetic Blend 15W-40 Diesel Engine Oil (1 Gallon, Case of 3)

It’s important to note this list does not cover every possible John Deere 4020 filter cross reference possible for these filters (there are likely hundreds of crosses). We only listed filters that have proven to be reliable and are readily available. Using filters from Wix, Baldwin, Donaldson or Fleetguard ensure that you are putting on a filter that has been tested to meet and actually usually exceed John Deere specs.

A John Deere 4020 is one of the most reliable tractors ever built, and proper and timely maintenance will keep it that way. When you can get filters for a reasonable price, you usually will change them at regular intervals (instead of putting it off). I encourage you to check the prices on our filter links, Amazon changes prices regularly, and the best deal today might not be the best deal tomorrow. We hope this article gives you enough John Deere 4020 oil filter cross reference information to save money while maintaining your tractor. Thanks for supporting our website!
