John Deere has announced that all Tier 4 engines in its lineup are now approved to run on B30 biodiesel blends, expanding from the earlier limit of B20. The announcement was made at the 2025 Farm Progress Show in Decatur, Illinois, where all equipment in the company’s Ride and Drive area is operating on B30, reports Chemanalyst.
Pierre Guyot, Senior Vice President of John Deere Power Systems, said the approval reflects the company’s push for renewable fuels. He noted that renewable fuels not only support a cleaner environment but also strengthen the agricultural economy, especially since many John Deere customers grow the crops used to make biodiesel.
The company has supported renewable fuels for decades. Tier 3/Stage III A and lower-tier engines are already cleared for biodiesel blends up to B100, while spark-ignition turf and utility machines can run on E10 ethanol. John Deere is also researching higher ethanol blends, including a concept 9.0L engine designed to run on near-pure ethanol (E98).
Industry leaders welcomed the move. Caleb Ragland, President of the American Soybean Association, called it a major boost for both farmers and rural communities, as higher biodiesel demand benefits soybean growers while offering cleaner fuel. Scott Fenwick, Technical Director of Clean Fuels Alliance America, said the approval reinforces biodiesel’s reliability and role in cutting emissions.
John Deere advised customers adopting B30 to work closely with fuel suppliers to ensure smooth integration into their operations.
With this step, the company strengthens its leadership in renewable fuel adoption, advancing sustainability in both agriculture and heavy equipment.
