The Death of DEF? Trump Says He’ll Roll Back Environmental Requirements to Cut Farm Equipment Costs

During a White House roundtable on Monday tied to a new $12 billion “bridge payment” plan, President Donald Trump said his administration will move quickly to ease environmental requirements affecting tractors and other farm machinery, arguing the changes will lower sticker prices and simplify repairs.

While the headline of the event was to announce the payments, which Trump says will be funded by tariff revenue, the roundtable discussion with farmers also revealed other actions the Trump administration is working on to reduce regulations. Trump told farmers Monday his administration plans to scale back environmental requirements on tractors and other farm equipment, framing the move as a way to bring down machinery costs that have climbed in recent years.

“The other thing I’d like to add … we’re going to also give the tractor companies, John Deere and all of the companies that make the equipment … we’re going to take off a lot of the environmental restrictions that they have on machinery,” Trump said. “It’s ridiculous.”

While Trump didn’t provide specifics on how the details of that plan will come together, Trump said EPA Administrator Lee Zeldin would be involved in carrying out the effort. There’s speculation on if that will be removing diesel exhaust fluid (DEF) requirements on tractors or also addressing the long-standing right-to-repair issue.

Earlier this year, EPA announced guidance to change, not eliminate, DEF requirements, allowing for softer power loss in new trucks (from model year 2027) when DEF runs low, preventing sudden shutdowns and enabling software fixes for existing vehicles, easing burdens on truckers and farmers. This guidance removed what EPA called “red tape,” allowing manufacturers to develop less disruptive fixes for performance issues caused by emissions systems, though it doesn’t legalize “deleting” emissions equipment.

EPA Says DEF Is “Unacceptable”

While Trump didn’t outline exactly what EPA plans to roll back, he hinted toward DEF being the target. Farm Journal reached out to EPA for clarification and comment, and EPA’s press secretary confirmed rolling back DEF requirements is the target for this administration.

“EPA has heard loud and clear from truckers and farmers across the United States that the Diesel Exhaust Fluid (DEF) system was unacceptable and cost millions of dollars in lost productivity,” Brigit Hirsch, EPA press secretary, told Farm Journal. “This summer, Administrator Zeldin issued clear guidance urging engine and equipment manufacturers to revise DEF system software in existing vehicles and equipment to prevent sudden shutdowns. It is essential manufacturers give operators more time to repair faults without impacting their livelihoods or safety. EPA will continue to evaluate ways to expand the work the agency has already done on DEF and looks forward to working across the administration to do so.”

She also pointed farmers toward EPA’s website dedicated to actions on Diesel Exhaust Fluid.

Trump Says “It Makes the Equipment Much More Expensive”

Trump argued added systems meant to meet environmental rules have driven up price tags and made equipment harder to operate and repair.

“You buy it, it’s got so much equipment on it for the environmental, it doesn’t do anything except it makes the equipment much more expensive and much more complicated to work,” he said, adding, “it’s not as good as the old days.”

Trump said the administration’s goal is to remove what he called “nonsense” and require manufacturers to pass savings along to farmers.

“And we’re going to do it, and we’re going to say: ‘You’re going to reduce the prices.’ We’re not going to do it, and they’re not going to reduce. They’re going to have to reduce their prices because farming equipment has gotten too expensive,” Trump said during the roundtable. “A lot of the reason is because they put these environmental excesses on the equipment which don’t do a damn thing except make it complicated, make it impractical.”

Trump Claims Modern Equipment is Overly Complex and Difficult to Service

Trump also described modern equipment as overly complex and more difficult for farmers to service themselves.

“For you really have to be, in many cases, you need about 185 IQ to turn on a lawn mower,” he said. “So we’re going to take that … off … that they put on Biden mostly.”

Trump claimed the changes would quickly impact costs, bringing down equipment prices and saying: “We’re going to do that immediately.”

“The machines, they’re always under repair because they’re so complicated that you can’t fix them,” “he said. The old days you used to fix it yourself. Now you can’t do that. You have to be a Ph.D. from, let’s say, MIT.”

Comments Came During Event Announcing $12 Billion in Bridge Payments

Trump made the remarks during a roundtable discussion with farmers at the White House that coincided with an announcement by the White House and USDA of $12 billion in bridge payments for farmers.

Up to $11 billion will go toward a newly designed Farmer Bridge Assistance (FBA) program targeted toward row crop farmers hit hardest by trade disruptions. Those payments will be sent by the end of February, according to U.S. Secretary of Agriculture Brooke Rollins. The remaining $1 billion will be set aside and is designated for other crops affected by the ongoing disputes.

USDA says the bulk of the funding will run through the new FBA program, administered by the Farm Service Agency (FSA) and funded under the Commodity Credit Corporation (CCC). Rollins framed the package as near-term help while trade and farm-safety-net updates ramp up.

John Deere Reacts

In a post on X following the announcement, John Deere commended the Trump administration’s announcement of relief and bridge payments for farmers saying: “The timely assistance will protect this essential industry, help rural communities and support critical long-term investments in the future of U.S. agriculture and manufacturing.”

John Deere also said it shares the administration’s focus on reducing costs for both producers and consumers.

“We are doing all we can to help U.S. farmers reduce input costs,” according to the post. “The equipment and technologies Deere makes here in the U.S. are giving American farmers new tools and technologies that can substantially reduce their input costs and labor costs while increasing yields, boosting margins.”

Those comments are drawing backlash from farmers and others online. Some argue if John Deere truly wants to help farmers, then they can start by lowering the price of their equipment. While others Deere will be one of the beneficiaries of farmers receiving these payments.
