Recently, the Trump administration gathered a variety of agricultural stakeholders, including prominent companies such as John Deere and AGCO, along with the American Farm Bureau Federation (AFBF), to discuss significant policy changes aimed at providing additional support for farmers and advancing the Farm Bill.

During the Great American Agriculture Celebration, President Trump unveiled several initiatives designed to alleviate costs for farmers, including the removal of Environmental Protection Agency (EPA) requirements for diesel exhaust fluid (DEF) sensors in machinery and the increase of nationwide ethanol blending this summer.

Removal of DEF Sensor Requirement

DEF systems are often prone to failures because of faulty sensors, which can lead to unexpected machine shutdowns, speed reductions, costly repairs, and productivity losses. The EPA estimates that by eliminating the sensor requirement, farmers could save approximately $4.4 billion per year, while American consumers could benefit from a total savings of about $13.79 billion annually.

Lee Zeldin, EPA administrator, addressed the importance of this change: “Americans are justified in being fed up with failing DEF system issues. EPA understands this is a massive issue and has been doing everything within our statutory power to address this. Today, we take another step in furthering our work by removing DEF sensors.”

John Deere, a major player in agricultural machinery, showcased its 8R 540 high-horsepower tractor at the event. The company expressed its approval of the changes, noting that false DEF-quality sensor readings could contribute to significant downtime. “Today’s announcement builds upon EPA guidance from February 2026, requested by John Deere, to provide farmers additional tools to complete emissions-related repairs,” stated Kyle Gilley, VP for global government affairs at John Deere. “These announcements are a win for farmers and their ability to keep modern equipment operating in the field.”

Nationwide E15 Fuel Waiver

In an emergency measure, the EPA has permitted the nationwide sale of gasoline blended with 15% ethanol (E15) for the summer season, alongside the removal of restrictions on E10 sales. This follows the finalization of the Renewable Fuel Standard “Set 2” rule, which will raise the renewable fuel volume requirements for 2026 and 2027 to unprecedented levels, according to an EPA press release.

Amid rising tensions related to the U.S. war with Iran, concerns about fuel and fertilizer availability have escalated, notably due to the closure of the Strait of Hormuz. As prices surged to around $114.81 per barrel for Brent crude oil on March 27, the new E15 measures aim to provide economic relief.

AFBF President Zippy Duvall recently expressed approval for the increased ethanol blending levels, emphasizing that “Biofuels play an important role in meeting America’s energy needs and are a win-win for farmers and drivers. E15 gasoline can save consumers between 10 to 30 cents per gallon, while also creating a substantial market for American-grown crops.” He further noted that permanent E15 sales would boost corn demand by roughly 2.4 billion bushels annually.

John Deere echoed this sentiment, with Gilley remarking, “Today’s Renewable Volume Obligations announcement sets blending volumes at record levels—providing farmers with stronger, more reliable demand for the crops they cultivate. This action supports rural economies, enhances fuel choice, and fosters American energy independence.”
