John Deere 4066R Filter Cross Reference Lists

The single most important maintenance step with any tractor is changing filters and oil regularly. Although they aren’t as cheap as they used to be, clean filters are still far, far cheaper than replacing engine parts or worse a whole engine. There are several high quality John Deere 4066R filter cross references available for the OEM filters on this tractor, with the exception of the cab fresh air filter. Most major filter brands these days make high quality filters, even Fram has come a long ways in reliability.

In the end the best filter for any tractor is a clean one, and we can’t stress enough how important changing oil and filters at the correct hour intervals is. We recommend a minimum of an oil, oil filter and fuel filter change out at the end of the year regardless of whether or not your hour meter says it’s time. It’s cheap insurance and makes you examine your machine more closely while doing the maintenance. Often times you will see something else that needs attention while reaching for that drain plug, that you otherwise might not have seen for months.
