John Deere announced Aug. 26 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, Illinois, where all John Deere equipment operated in the company’s ride-and-drive area will run on B30 biodiesel. 

“At John Deere, we’re committed to supporting and growing the use of renewable fuels in our equipment,” said Pierre Guyot, the senior vice president of John Deere Power Systems.

“We believe strongly in the role that renewable fuels play in supporting the agriculture economy and are excited to offer our customers—including those who grow the very crops used to make renewable fuels—the opportunity to leverage higher blends of fuels like biodiesel in their own equipment,” Guyot added.

John Deere has a long history of supporting renewable fuel use in its equipment.  

Prior to the Aug. 26 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 are approved for E10 ethanol blends.  

John Deere is also exploring the use of higher ethanol blends in future engine solutions, including the development of a concept 9.0-liter 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.  

“This is a win-win situation for U.S. soybean farmers and rural communities,” said Caleb Ragland, president of the American Soybean Association and Kentucky soybean farmer. “Higher blends of biodiesel mean greater demand for the soybeans we grow and cleaner-burning fuel for equipment in the field. John Deere’s leadership in approving the utilization of B30 in their machinery helps move renewable fuels forward while directly supporting the farmers who help produce them.”  

Scott Fenwick, the technical director for Clean Fuels Alliance America, added, “John Deere’s approval of B30 demonstrates true leadership in supporting America’s farmers and advancing sustainable fuels. Biodiesel is engineered to deliver the performance fleets and equipment owners expect, while exceeding ASTM quality specifications. By embracing higher blends, John Deere is assuring customers they can rely on a clean, homegrown fuel that reduces carbon emissions and strengthens rural economies.”
