Why American Farmers Are Hacking Their Tractors With Ukrainian Firmware
A dive into the thriving black market of John Deere tractor hacking.
To avoid the draconian locks that John Deere puts on the tractors they buy, farmers throughout America's heartland have started hacking their equipment with firmware that's cracked in Eastern Europe and traded on invite-only, paid online forums.
Tractor hacking is growing increasingly popular because John Deere and other manufacturers have made it impossible to perform "unauthorized" repair on farm equipment, which farmers see as an attack on their sovereignty and quite possibly an existential threat to their livelihood if their tractor breaks at an inopportune time.
"When crunch time comes and we break down, chances are we don't have time to wait for a dealership employee to show up and fix it," Danny Kluthe, a hog farmer in Nebraska, told his state legislature earlier this month. "Most all the new equipment [requires] a download [to fix]."
The nightmare scenario, and a fear I heard expressed over and over again in talking with farmers, is that John Deere could remotely shut down a tractor and there wouldn't be anything a farmer could do about it.
"What you've got is technicians running around here with cracked Ukrainian John Deere software that they bought off the black market"
A license agreement John Deere required farmers to sign in October forbids nearly all repair and modification to farming equipment, and prevents farmers from suing for "crop loss, lost profits, loss of goodwill, loss of use of equipment … arising from the performance or non-performance of any aspect of the software." The agreement applies to anyone who turns the key or otherwise uses a John Deere tractor with embedded software. It means that only John Deere dealerships and "authorized" repair shops can work on newer tractors.
"If a farmer bought the tractor, he should be able to do whatever he wants with it," Kevin Kenney, a farmer and right-to-repair advocate in Nebraska, told me. "You want to replace a transmission and you take it to an independent mechanic—he can put in the new transmission but the tractor can't drive out of the shop. Deere charges $230, plus $130 an hour for a technician to drive out and plug a connector into their USB port to authorize the part."
"What you've got is technicians running around here with cracked Ukrainian John Deere software that they bought off the black market," he added.
Kenney and Kluthe have been pushing for right-to-repair legislation in Nebraska that would invalidate John Deere's license agreement (seven other states are considering similar bills). In the meantime, farmers have started hacking their machines because even simple repairs are made impossible by the embedded software within the tractor. John Deere is one of the staunchest opponents of this legislation.
"There's software out there a guy can get his hands on if he looks for it," one farmer and repair mechanic in Nebraska who uses cracked John Deere software told me. "I'm not a big business or anything, but let's say you've got a guy here who has a tractor and something goes wrong with it—the nearest dealership is 40 miles away, but you've got me or a diesel shop a mile away. The only way we can fix things is illegally, which is what's holding back free enterprise more than anything and hampers a farmer's ability to get stuff done, too."

I went searching for one of the forums where pirated John Deere firmware is sold. After I found it, I couldn't do much of anything without joining. I was sent an email with instructions, which required me to buy a $25 dummy diagnostic part from a third-party website. Instead of the part, I was sent a code to join the forum.
Once I was on it, I found dozens of threads from farmers desperate to fix and modify their own tractors. According to people on the forums and the farmers who use it, much of the software is cracked in Eastern European countries such as Poland and Ukraine and then sold back to farmers in the United States.
Among the programs I saw being traded:
John Deere Service Advisor: A diagnostic program used by John Deere technicians that recalibrate tractors and can diagnose broken parts. "It can program payloads into different controllers. It can calibrate injectors, turbo, engine hours and all kinds of fun stuff," someone familiar with the software told me.
John Deere Payload files: These are files that specifically program certain parts of the vehicle. There are files that can customize and fine-tune the performance of the chassis, engine, and cab, for instance.
John Deere Electronic Data Link drivers: This is software that allows a computer to talk to the tractor. "The EDL is the required interface which allows the Service Advisor laptop to actually communicate with the tractor controllers," the source told me.
A reverse engineer who goes by Decryptor Tuning, who I met on a forum, told me they distribute programs that are "usually OEM software that is freely available but must be licensed."
"If things could get better, [companies like John Deere] should be forced to freely distribute the same software dealers have," they said. "And stop locking down [Engine Control Module] reading functionality. They do this to force you to use their services, which they have a 100 percent monopoly on."
Also for sale (or free download) on the forums are license key generators, speed-limit modifiers, and reverse-engineered cables that allow you to connect a tractor to a computer. These programs are also for sale on several sketchy-looking websites that are hosted in Europe, and on YouTube there are demos of the software in operation.
On its face, pirating such software would seem to be illegal. But in 2015, the Librarian of Congress approved an exemption to the Digital Millennium Copyright Act for land vehicles, which includes tractors. The exemption allows modification of "computer programs that are contained in and control the functioning of a motorized land vehicle such as a personal automobile, commercial motor vehicle or mechanized agricultural vehicle … when circumvention is a necessary step undertaken by the authorized owner of the vehicle to allow the diagnosis, repair, or lawful modification of a vehicle function."
This means modification of embedded software is legal long as it can still meet emission requirements. Whether the exemption allows for the downloading of cracked software is an unanswered question.
"Are we supposed to throw the tractor in the garbage, or what?"
It's no surprise, then, that John Deere started requiring farmers to sign licensing agreements around the time the exemption went into effect. Violation of the agreement would be considered a breach of contract rather than a federal copyright violation, meaning John Deere would have to sue its own customers if it wants the contract to be enforced. I asked John Deere specifically about the fact that a software black market has cropped up for its tractors, but the company instead said that there are no repair problems for John Deere customers.
"When a customer buys John Deere equipment, he or she owns the equipment," the company said. "As the owner, he or she has the ability to maintain and repair the equipment. The customer also has the ability through operator and service manuals and other resources to enable operational, maintenance, service and diagnostics activities to repair and maintain equipment."
"Software modifications increase the risk that equipment will not function as designed," the company continued. "As a result, allowing unqualified individuals to modify equipment software can endanger machine performance, in addition to Deere customers, dealers and others, resulting in equipment that no longer complies with industry and safety/environmental regulations."
Gay Gordon-Byrne, executive director of Repair.org, a trade organization fighting for right-to-repair legislation, told me that John Deere's statement is "total crap," and noted that "some of our members have repeatedly attempted to buy the diagnostics that are referenced [from John Deere] and been rebuffed."
"They require buyers to accept an End User License Agreement that disallows all of the activities they say are allowed in their statement," she said. "Deere is a monopolist and has systematically taken over the role of equipment owner, despite having been paid fairly and fully for equipment. Their claims to control equipment post-purchase are inconsistent with all aspects of ownership including accounting, taxation, and transfer of products into the secondary market."
It's quite simple, really. John Deere sold farmers their tractors, but has used software to maintain control of every aspect of its use after the sale. Kluthe, for example, uses pig manure to power his tractor, which requires engine modifications that would likely violate John Deere's terms of service on newer machines.
"I take the hog waste and run it through an anaerobic digester and I've learned to compress the methane," he said. "I run an 80 percent methane in my Chevy Diesel Pickup and I run 90 percent methane in my tractor. And they both purr. I take a lot of pride in working on my equipment."
Farmers worry what will happen if John Deere is bought by another company, or what will happen if the company decides to stop servicing its tractors. And so they have taken matters into their own hands by taking control of the software themselves.
"What happens in 20 years when there's a new tractor out and John Deere doesn't want to fix these anymore?" the farmer using Ukrainian software told me. "Are we supposed to throw the tractor in the garbage, or what?"
If you work for a John Deere dealership or are a farmer who has been hurt by the company's stance on repair, tell me your story—here's how you can contact me securely.
