Right to Repair

More DEF Relief? EPA Takes New Action for Farmers and Truckers

Tue, 03 Feb 2026 16:14:42 GMT

On the heels of clarifying farmers’ right to repair their own equipment, EPA is escalating pressure on diesel engine manufacturers over ongoing Diesel Exhaust Fluid (DEF) system failures the administration claims continue to sideline farm machinery and trucks.

On Tuesday, EPA Administrator Lee Zeldin announced the agency is demanding detailed failure data from major diesel engine manufacturers as it considers additional rules aimed at reducing DEF-related shutdowns and derates that have plagued farmers, truckers and equipment operators for years.

The move builds directly on Monday’s EPA right-to-repair guidance announcement that clarified the Clean Air Act does not prohibit farmers from fixing their own non-road diesel equipment, which includes making temporary emissions overrides when necessary to complete repairs.

“As I traveled to all 50 states during my first year as EPA administrator, I heard from truck drivers, farmers and many others rightly complaining about DEF and pleading for a fix,” Zeldin said in a statement on Tuesday. “EPA understands this is a massive issue, which is why we have already established commonsense guidance for manufacturers to update DEF systems.

“Today, we are furthering that work and demanding detailed data to hold manufacturers accountable for the continued system failures,” he added.

While neither announcement fully rolls back DEF requirements on tractors, a step many farmers and truckers continue to push for, both signal movement in that direction.

With today’s news in the mix, here’s what farmers and truckers need to know:

1. Increased Operational Up-Time.

The most immediate benefit is the reduction of “forced downtime.” Under the clarified guidance announced on Feb. 2, farmers can now perform temporary emissions overrides to complete essential work, such as planting or harvesting, even if a DEF failure occurs. The extension of warning periods — specifically the 36-hour window for non-road equipment before a derate kicks in — provides a buffer to finish a job before seeking repairs.

2. Legal Empowerment for Repairs.

EPA has explicitly stated the Clean Air Act cannot be used by manufacturers as a shield to prevent farmers from fixing your own equipment. This clarification removes a major legal hurdle in the right-to-repair movement, potentially lowering repair costs by allowing farmers and independent mechanics to access the tools and software needed to address DEF-related faults.

3. Manufacturer Accountability.

Under Section 208(a) of the Clean Air Act, EPA is demanding warranty and failure data for Model Year 2016, 2019 and 2023 engines from 14 major on-road and non-road diesel manufacturers (covering 80% of the market). That shifts the burden of DEF reliability from the end-user to the manufacturer. EPA says the information will help determine whether persistent DEF problems are tied to specific product generations, system designs or materials, and will inform further regulatory steps in 2026. Manufacturers have 30 days to comply or face potential enforcement actions.

4. Impact on Machinery Values.

Auction data suggests farmers are already voting with their checkbooks. According to Machinery Pete , demand and values remain strongest for pre-DEF used equipment, while interest in DEF-equipped machinery has softened.

If these EPA actions lead to more reliable DEF systems or easier repairs, the high demand (and inflated prices) for older, less efficient equipment might eventually stabilize as newer models become less of a liability in the field.

5. More Changes are Coming.

When asked why EPA has not eliminated DEF requirements entirely,Zeldin said the agency said it is actively building on last summer’s guidance and actively moving toward “common-sense” adjustments that prioritize productivity alongside emissions standards.

EPA’s demand for warranty and failure data follows DEF guidance issued in August 2025 that significantly softened inducement rules. That guidance delayed severe derates, reduced sudden shutdowns and required manufacturers to update software so operators could continue safely working while addressing faults.

For heavy-duty trucks, warning periods were extended to up to 650 miles or 10 hours before derates begin, with weeks of normal operation allowed before speed is limited. Non-road equipment now sees no impact for the first 36 hours after a DEF fault.

EPA has also said that starting with Model Year 2027, new diesel trucks must be engineered to avoid sudden and severe power loss after running out of DEF.

EPA Backs Farmers, Affirms Right to Repair Equipment

Mon, 02 Feb 2026 17:42:08 GMT

EPA issued new right-to-repair guidance on Monday, clarifying how the Clean Air Act applies to non-road diesel equipment. It’s a move EPA Administrator Lee Zeldin says is intended to end years of confusion and misuse of the law that has limited farmers’ ability to fix their own machinery.

“Unfortunately, equipment manufacturers have misused the Clean Air Act by falsely claiming that environmental laws prevented them from making essential repair tools or software available to all Americans,” he says. “Because of this misinterpretation of the law, manufacturers have limited the ability of farmers and independent repair shops to repair equipment.”

How Much Will Right to Repair Save the Average Farm?

According to Kelly Loeffler, Small Business Administration (SBA) administrator, the savings could be $48 billion across agriculture. For an individual farm, that could mean:

$33,000 in savings per repair
$3,000 to $4,000 in potential yield losses avoided due to reduced downtime
10% reduction in annual operating costs
Up to 80% reduction in repair costs annually

Loeffler says savings come from avoiding dealer-only repairs, reducing downtime during critical fieldwork windows, and eliminating transportation and labor delays tied to authorized service requirements.

The news came as a joint announcement on Feb. 2 with Loeffler as well as USDA Secretary Brooke Rollins.

“Today we are issuing guidance out of the Trump EPA to make abundantly clear that if you own your farm and other non-road diesel equipment, you have the right to fix it,” Zeldin says. “This might seem like a no-brainer, but ask any American farmer and they will tell you about the headaches and costly hassles that they have been forced to endure at the hands of equipment manufacturers.”

Zeldin says manufacturers have relied on what he calls a false interpretation of the Clean Air Act to restrict access to repair tools, software and diagnostic systems. He says today’s announcement will make that new guidance clear.

What EPA’s Announcement Didn’t Include? A Complete Rollback of DEF

Following today’s right-to-repair announcement, Farm Journal asked EPA why the administration isn’t also removing Diesel Exhaust Fluid, or DEF, requirements for farm equipment. Farmers have long cited DEF as a major contributor to rising equipment costs, particularly compared with competitors in Brazil, for example. In summer 2025, EPA issued guidance relaxing DEF “inducement” requirements, and today’s announcement focuses on allowing farmers to temporarily override DEF when making repairs.

In response, EPA says the agency is actively building on last summer’s DEF guidance.

“As Administrator Zeldin mentioned on today’s press call, EPA is actively working to build upon the DEF guidance the agency issued this summer,” the press office wrote. “EPA understands DEF is a major issue facing farmers, truck drivers and equipment operators. The agency will be making an announcement on DEF in the near future.”

This indicates that while today’s right-to-repair guidance stops short of changing DEF rules, additional updates could be coming soon.

Downtime, Dealer Dependence and Lost Productivity

Zeldin says farmers are often forced to rely exclusively on authorized dealerships for repairs, even during critical times like during planting and harvest when downtime costs farmers time and money.

“Instead of a farmer being able to fix their own equipment in the field or bring it down the road to their local repair shop, farmers have been forced to rely solely on authorized dealers for essential repairs, which are not always close by,” he says. “For farmers, timing is everything. When equipment breaks down during planting or harvesting, delays can result in thousands of dollars in lost productivity.”

He adds that the financial burden goes beyond inconvenience.

“Being forced to haul machinery to a certified dealership, pay higher prices for repairs and wait in line; it’s not just inconvenient,” Zeldin says. “It can prove to be very economically damaging.”

The Future of DEF: Is an Emissions Rollback Coming?

This latest right-to-repair announcement builds on action taken by the Trump administration in August 2025, when EPA issued guidance addressing diesel exhaust fluid, or DEF, system failures in farm equipment. The 2025 guidance aimed to address widespread frustration among farmers with Tier 4 emissions technology, while maintaining long-term environmental protections.

Prior to that announcement, in early June, John Deere sent a letter to EPA, asking the agency to clarify that temporary emissions overrides are allowed. In response, EPA issued guidance on Aug. 12 and later urged DEF system software updates to prevent sudden shutdowns, helping farmers and equipment operators make repairs without losing productivity or safety.

The new right-to-repair guidance announced today by EPA, USDA and SBA aims to extend this administration’s approach by clarifying farmers’ ability to make essential repairs themselves, which they claim will further improve reliability, efficiency and cost savings on the farm.

If you go back to the Trump administration’s original announcement last summer, EPA said it would allow manufacturers to update DEF system software to prevent abrupt power loss in tractors, trucks and other diesel machinery. The goal was to reduce “red tape” and prevent equipment shutdowns during critical planting and harvest periods, while still maintaining emissions controls.

Key aspects of the 2025 DEF guidance included:

Reduced Derating: Instead of immediate, severe speed and power reductions when DEF levels are low or sensors fail, engines could now slow down more gradually, reducing disruption in the field.
“Soft” Power Loss for New Models: For 2027 and later models, engines were required not to shut down or lose power abruptly if DEF ran out.
Software Fixes for Existing Equipment: Manufacturers could issue software updates to ensure older machinery properly handled low-DEF scenarios.
No Deleting Permitted: Emissions equipment could not be removed, and the guidance did not legalize deleting any system.

EPA says the announcement meant tractors and machinery were less likely to experience sudden, catastrophic power loss, which would reduce downtime.

USDA: Right to Repair Is Important for Everyday Farm Operations

USDA Secretary Brooke Rollins says the administration has been working on the guidance for months because of its importance to everyday farm operations.

“We have been working on today’s guidance now for a while because we know how much it means for the everyday farmer,” Rollins says. “The right to repair isn’t just a slogan. It’s a common-sense extension of the God-given right to private property.”

Rollins ties equipment downtime directly to food production and national security.

“Every single day our farmers feed us, they fuel us, they clothe us,” she says. “But when that equipment breaks down and remains out of operation, it means crops aren’t planted or harvested, mouths aren’t fed, and America’s economic growth and national security are put at risk.”

She says farmers overwhelmingly agree they should be able to repair their own equipment, an issue USDA has been hearing since President Trump took office more than a year ago.

“Farmers shouldn’t be forced to haul their equipment to specialized and costly repair shops when they could be making those repairs on their own,” Rollins says. “An overwhelming majority of farmers, north of 95%, agree with that statement.”

What Does the New EPA Right to Repair Guidance Allow?

Zeldin stresses the guidance does not weaken emissions standards or change the Clean Air Act.

“It does not change the law, and it does not reduce compliance obligations,” he says. “What it does do is stop the law from being misused to block common-sense repairs.”

The guidance clarifies that equipment owners may temporarily override emissions systems — including diesel exhaust fluid (DEF) systems — when necessary to complete a repair, as long as the equipment is returned to compliance.

“At times, a tractor might just stop working altogether in the middle of harvest because of a DEF issue,” Zeldin says. “This allows farmers to fix broken DEF systems right there at home or in the field.”

SBA: ‘Huge Relief’ with Measurable Savings

Small Business Administration Administrator Kelly Loeffler says the guidance delivers significant, quantifiable savings for farmers.

“I’m the product of one of the 1.9 million farms in this great nation that feed, fuel and clothe our country,” Loeffler says. “Diesel exhaust fluid and now right to repair — these are huge-relief, common-sense reforms.”

Loeffler says SBA economists worked to quantify the impact farm by farm.

“In the aggregate, this is about a $48 billion savings,” she says. “It’s about $33,000 per repair.”

She adds that downtime drives additional losses.

“The loss of yield could be up to $3,000 to $4,000 for the average farm,” Loeffler says. “That’s time spent leaving the field, missing a window of dry weather and dealing with delays in parts and labor.”

According to Loeffler, the guidance could reduce annual operating costs by roughly 10% and cut repair costs dramatically.

“This could potentially reach an 80% annual reduction in the cost of repairs,” she says. “And we know those repairs are getting even more expensive.”

John Deere Say’s EPA’s Guidance Responds to Formal Request

John Deere says the EPA’s right-to-repair guidance directly responds to a formal request the company made to the agency in June 2025 .

In a statement, John Deere says it sought updated guidance from EPA to expand repair options for customers and independent technicians while still ensuring compliance with federal emissions requirements.

“John Deere appreciates today’s action by EPA Administrator Zeldin, which responds directly to a formal request made by the company in June 2025,” the company says. “John Deere sought this updated guidance from the EPA with the intent to further increase customers’ and independent repair technicians’ repair capabilities while ensuring compliance with EPA requirements and guidance.”

The company says its request aligns with its long-standing position that customers should have flexibility in how their equipment is repaired.

“John Deere’s request to the EPA is consistent with the company’s longstanding commitment to supporting customer choice on how equipment is repaired — whether through their trusted John Deere dealer, with a local service provider, or by doing the work themselves,” the statement says.

John Deere adds that in light of the updated EPA guidance, it plans to roll out new repair functionality for customers.

“The temporary inducement override capability will soon be made available to John Deere customers through Operations Center™ PRO Service,” the company says, describing the platform as an enhanced digital repair tool that provides diagnostic, repair and reprogramming capabilities.

The company says additional information about the tool is available through its website.

Trump Administration Frames Announcement as Farmer Choice and Independence

All three officials frame the announcement as centered on farmer independence.

“This is about fairness, competition and independence,” Zeldin says. “Farmers should be able to choose where and how their equipment is repaired.”

“In America, the timely, affordable maintenance of agricultural equipment should not be a luxury,” Rollins says. “It should be a given.”

“And coming from a multigenerational farm family, this issue is very personal,” Loeffler says. “We’re going to continue to make sure farmers get the regulatory relief they deserve.”

Is The Death of DEF Coming Soon?

While today’s announcement is another step in reducing regulations and emissions standards, EPA didn’t go as far as to eliminate DEF requirements on farm equipment, but told Farm Journal an announcement on that is coming soon.

Industry analysts say a rollback of federal emissions requirements on machinery could send shockwaves through both the new and used equipment markets, though exactly how depends on how far any policy would go and how manufacturers respond.

Greg Peterson, widely known as “Machinery Pete,” says the biggest immediate impact would be on used equipment values, particularly older, pre-emissions models that farmers already favor.

Emissions Rollback Could Reshape Machinery Markets, Analysts Say

Peterson points to years of auction data showing strong demand, as well as rising prices for good-condition pre-DEF tractors and combines, even during tight grain markets. If emissions rules were suddenly relaxed, he says the industry would be entering uncharted territory.

“The wild card is what happens to that one-, two-, three-, four-, five- and six-year-old equipment that’s already out there,” Peterson says. “It would be unprecedented.”

Opportunity and Uncertainty for Dealers and OEMs

While that uncertainty could create short-term friction, Peterson also sees opportunity. If manufacturers were allowed to build simpler machines again, it could align more closely with what many farmers are already voting for with their checkbooks.

“That’s what farmers want,” Peterson says, noting the continued premium buyers are willing to pay for older machines without complex emissions systems.

He adds that such a shift could be “an unbelievable opportunity” for both manufacturers and dealers, depending on how quickly and cleanly changes could be implemented at the factory level.

Manufacturers Unlikely to Fully Abandon Emissions Systems

Casey Seymour, host of the ‘ Moving Iron ’ podcast, agrees the used equipment market could benefit, but he’s skeptical manufacturers would abandon emissions technology altogether.

Seymour says the bigger issue for OEMs is regulatory whiplash. Environmental rules can change dramatically from one administration to the next, making it risky to retool factories for non-emissions machines only to reverse course a few years later.

“I don’t see a manufacturer of any color completely stepping back and saying we’re not going to worry about this anymore,” Seymour says.

Flexibility Could Boost Used Equipment Values

Instead, if EPA would decide to roll back emissions standards, Seymour envisions machines leaving the factory “emissions-ready,” giving farmers flexibility down the road. If deleting emissions systems became legal, equipment could be modified and resold without violating regulations, opening new possibilities in the secondary market.

That shift, Seymour says, could actually strengthen used equipment values. Demand for legally modified machines could rise, and farmers would no longer need to remove emissions components illegally.

Both analysts agree the used market would likely react first to any regulatory change, while new equipment pricing may remain largely unchanged unless manufacturers gain long-term certainty on emissions policy.

Right To Repair Granted? John Deere Launches Digital Self-Repair Tool for $195 Per Tractor

Thu, 31 Jul 2025 15:51:28 GMT

In what appears to be a direct response to anti-competition claims raised in the ongoing FCC v. John Deere Right to Repair lawsuit , the equipment manufacturer has released an updated digital service tool to enable equipment owners to maintain, diagnose, repair and protect farm equipment.

The new Operations Center PRO Service tool is available now in John Deere’s Operation Center app to equipment owners in the U.S. and Canada.

John Deere says it will charge farmers an annual license starting at $195 per machine for the tool. The company is charging independent service professionals $5,995.00 per year, which includes up to 10 local downloads.

The increased functionality of the new service tool replaces John Deere’s previous digital service iteration, known as Customer Service ADVISOR. John Deere representatives confirm ADVISOR will be phased out over the next year.

What farmers need to know

John Deere says the new Operations Center PRO Service “delivers digital repair content filtered by year and model number and provides users with additional relevant machine information to help troubleshoot, diagnose and repair Deere equipment. It’s designed to be intuitive and deliver support in real time.”

Here are the new service and repair capabilities within the tool:

Machine health insights and diagnostic trouble codes
PIN-specific machine content, including manuals
Software reprogramming for John Deere controllers
Diagnostic Readings
Diagnostic Recordings
Interactive diagnostic tests
Calibrations

Quick Analysis

If you’ve been following the FCC v. John Deere Right to Repair lawsuit, you may recall FCC’s legal team asking the equipment manufacturer to release a full digital repair and diagnosis tool for farmers and independent service technicians as part of its filed request for injunctive relief.

Related: What Does Right to Repair Really Mean?

Right to Repair advocates and antitrust attorney James Kovac, along with the FCC’s legal team, at the time were critical of the Customer Service ADVISOR, calling it an incomplete diagnostic tool. Kovacs himself says “independent repair pros and the farmers have access to (the tool), but (it) doesn’t give them the full suite of options to repair all the needs of their farming equipment.”

What John Deere is saying about the new tool

“Our development of these tools reaffirms John Deere’s support of customer self-repair,” says Denver Caldwell, vice president of aftermarket and customer support with John Deere. “We view continuously enhancing self-repair as consistent with our mission to ensure John Deere customers have the best machine ownership experience possible.”

What about independent repair technicians?

On the John Deere online store, it currently lists a Operations Center PRO Service annual license for a “Service Business” as costing $5,995.00 . The license provides for 10 local downloads of the PRO Service application, the listing says.

“Our message to our customers is clear,” Caldwell continues. “Whether you want the support of your professionally trained and trusted John Deere dealer, to work with another local service provider or to fix your machine yourself, we’ve created additional capabilities for you to choose the option that best fits your needs.”

How does it work?

Equipment owners must access Operations Center PRO Service through the John Deere Operations Center. Once connected to the platform, owners will add their equipment into their account using the machine’s serial number. Use of an electronic data link might be required for more advanced features within Operations Center PRO Service, including software reprogramming. Certain interactive tests, calibrations and reprogramming limitations will exist at initial release.

John Deere says it will deliver additional capabilities in future updates. See JohnDeere.com/PROService for further details.
