John Deere approves B30 biodiesel across engines, boosting renewable fuel use, supporting farmers, reducing emissions, and strengthening agricultural sustainability.
John Deere has officially announced that all Tier 4 engines in its portfolio are now approved for the use of B30 biodiesel fuel blends. This move marks a significant step forward from the company’s earlier approval of biodiesel blends up to B20. The announcement is being showcased at the 2025 Farm Progress Show in Decatur, Illinois, where all equipment operating in John Deere’s Ride and Drive area is running on B30 biodiesel.
Pierre Guyot, Senior Vice President of John Deere Power Systems, emphasized the importance of this advancement, stating, “At John Deere, we’re dedicated to expanding the use of renewable fuels within our equipment. Renewable fuels play a crucial role in strengthening the agriculture economy, and we are proud to provide our customers — many of whom produce the crops used in making biodiesel — with the opportunity to benefit from higher fuel blend approvals.”
John Deere has a longstanding history of supporting renewable fuels. Before today’s announcement, all Tier 4 engines were approved for use with B20 biodiesel and RD100 renewable diesel. Meanwhile, Tier 3/Stage III A and lower-tier engines were cleared for blends up to B100, offering flexibility for customers with older equipment. In addition, the company’s spark ignition turf and utility machines have long been compatible with E10 ethanol. Looking ahead, John Deere is actively researching the potential for higher ethanol blends in future engine technologies. Among these efforts is the development of a concept 9.0L ethanol engine designed to run on E98, underscoring the company’s commitment to exploring diverse renewable energy pathways.
For customers interested in adopting higher blends such as B30, John Deere recommends working closely with fuel suppliers to ensure seamless integration into operations.
The announcement has also drawn strong praise from agricultural and renewable fuel industry leaders. Caleb Ragland, President of the American Soybean Association and a soybean farmer from Kentucky, described the move as “a win-win for both farmers and rural communities.” He noted that increased biodiesel demand directly benefits soybean growers while delivering cleaner-burning fuel for farm equipment. Ragland highlighted how John Deere’s leadership reinforces the role of farmers in producing sustainable energy solutions.
Scott Fenwick, Technical Director of Clean Fuels Alliance America, echoed these sentiments, applauding John Deere for its proactive stance in advancing renewable fuel adoption. He explained that biodiesel is engineered to meet and exceed ASTM quality standards while providing reliable performance. According to Fenwick, John Deere’s decision reassures customers that they can depend on biodiesel as a clean, domestically produced fuel option that reduces carbon emissions and strengthens rural economies.
With this expanded approval, John Deere continues to position itself at the forefront of sustainable fuel integration in the agriculture and heavy equipment sectors, directly supporting both environmental goals and farming communities.
