John Deere approves B30 across its entire portfolio of Tier 4 engines

In Illinois, John Deere announced the approval of B30 biodiesel use across its entire portfolio of Tier 4 John Deere engines. This increases the previous approval of blends up to B20. The announcement will also be highlighted this week at the 2025 Farm Progress Show in Decatur, IL, where all John Deere equipment operated in the company’s Ride and Drive area will run on B30 biodiesel.

John Deere has a long history of supporting renewable fuel use in its equipment. Prior to the announcement, all Tier 4 John Deere engines were approved for B20 biodiesel and RD100 renewable diesel, with all Tier 3/Stage III A and lower tier engines approved for biodiesel blends up to B100. In addition, all John Deere spark ignition turf and utility equipment is approved for E10 ethanol blend. John Deere is also exploring the use of higher ethanol blends in future engine solutions, including the development of a concept 9.0L ethanol engine that runs on E98. Customers interested in incorporating higher renewable fuel blends including B30 into their operations are encouraged to consult their fuel supplier.
