John Deere recently 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.

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

John Deere has long supported renewable fuel use in its equipment. Until now, Tier 4 engines were cleared for B20 biodiesel and RD100 renewable diesel, while Tier 3/Stage IIIA and older models could use biodiesel blends up to B100. The company’s spark-ignition turf and utility machines are already approved for E10, and engineers are even testing a concept 9.0-liter ethanol engine that runs on E98. Customers looking to move to higher renewable fuel blends, including B30, should check with their fuel supplier.

“This is a win-win situation for U.S. soybean farmers and rural communities,” said Caleb Ragland, Kentucky soybean farmer and president of the American Soybean Association. “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.”

“John Deere’s approval of B30 demonstrates true leadership in supporting America’s farmers and advancing sustainable fuels,” said Scott Fenwick, technical director for Clean Fuels Alliance America. “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.”

John Deere is committed to expanding the production and use of renewable fuels across all modes of transportation to support farmers, consumers, and the rural economy while also helping reduce emissions.
