The Latest John Deere Repair Lawsuit Now Has The Go-Ahead

December 8, 2023 by 50 Comments

Long time readers will have followed the twists and turns of the John Deere repair saga, in which the agricultural machinery manufacturer has used DRM to restrict the repair of its tractors. It may be hot stuff on the prairies, but it matters to everyone because it’s a key right-to-repair battleground. Now the company’s attempt to throw out the latest class-action lawsuit, this time in Illinois. has failed, paving the way for a meaningful challenge.

This lawsuit is special because has the aim of determining whether or not Deere conspired to drive up the cost of repair and edge out independent mechanics. It comes against a backdrop in which their promised access to repair software which we reported on back in January has failed to materialize, and this is likely to figure as an act of bad faith.

A failing of corporate culture is that the organisation can in its own eyes, never be wrong. In Deere’s case they have accrued plenty of bad publicity in the years they’ve pursued this ill-advised business model, and in case that weren’t enough they’ve alienated their core customers out on the farms to the extent that a second-hand Deere from before the DRM era has more value than its newer counterparts. Deere genuinely do make very good tractors, so for farmers loyal for generations to turn their backs on them is a very significant story indeed. One has to ask, how much bad publicity and how many lawsuits do they have to have before someone at head office in Moline figures out that DRM in tractors (or anything else for that matter) isn’t the great idea they once thought it was? Maybe this one will finally herald the moment when that happens.

The World’s First Agricultural Right To Repair Law

April 29, 2023 by 29 Comments

Long time readers will know that occasionally we mix up our usual subject matter with a dash of farm equipment. Usually the yellow and green variants that come from John Deere, as the agricultural manufacturer has become the poster child for all that is wrong in the fight for the right to repair. An old Deere is worth more than a nearly new one in many places, because for several years now their models have had all their parts locked down by DRM technologies such that only their own fitters can replace them. Now after a long legal fight involving many parties, the repair and parts company iFixit sound justifiably pleased as they announce the world’s first agricultural right to repair law being passed in the US state of Colorado. (Nitter)

This may sound like a small victory, and it will no doubt be followed by further rearguard actions from the industry as similar laws are tabled in other states. But in fact as we read it, with this law in place the game is de facto up for the tractor makers. Once they are required to release any access codes for the Coloradans those same codes will by extension be available to any other farmers, and though we’re guessing they won’t do this, they would be best advised to give up on the whole DRM idea and concentrate instead on making better tractors to fix their by-now-damaged brands.

It’s exciting news for everybody as it proves that right-to-repair legislation is possible, however since this applies only to agricultural machinery the battle is by no means over. Only when all machines and devices have the same protection can we truly be said to have achieved the right to repair.

We’ve reported on this story for a long time, here’s a previous piece of legislation tried in another state.

You Can Now Fix Your Deere

January 9, 2023 by 29 Comments

Over the last few years we have brought you many stories about John Deere tractors, and how their repair has been locked down such that only manufacturer-authorised technicians can work on them. They’ve become a poster child in the battle for the right to repair, a symbol of the worst practices. Finally now we can bring you some good news of sorts, as the agricultural giant has signed a memorandum of understanding with the American Farm Bureau Federation to ensure that their products will henceforth be repairable by people without Deere approval.

We can’t imagine that Deere will have taken this step willingly, and while we’d like to imagine that consumer protests in favour of right-to-repair have hit their mark, we’re guessing that it’s more of an economic pressure at work alongside the threat of legislation outside their native America. If farmers getting caught out waiting for a Deere van to arrive while their crop withers in the field wasn’t enough, when the price of a second-hand tractor without the DRM outstrips that of a newer one with it, eventually the sales of new tractors will also suffer.

So this is good news, and we’re guessing that other agricultural manufacturers doing the same DMCA practices will now follow suit. But it’s not a complete victory. The problem starts not with the DMCA restriction itself, but with the extension of the machine’s computer system into every part, including those many parts which simply don’t need it. It’s not a complete victory if anyone can now use the software to register a new hydraulic valve with the system; instead that hydraulic valve should not have to be authorised in the first place. It’s this creeping unnecessary complexity which is the true enemy of right-to-repair, and we shouldn’t forget that.

Finally We Can Watch The Deere Cracking Def Con Talk

September 12, 2022 by 12 Comments

A few weeks ago, some tantalizing social media posts emerged from a Def Con talk, in which [Sick Codes] broke into the screen control unit for a John Deere tractor live on stage, and proceeded to play a special Deere-themed DOOM level upon it. At the time there was nothing more to go on, but we’re pleased to find out that the whole talk has been put online.

The talk starts with an introduction to the topic, to the basics of the control units within the machine and to the various different ages of Deere screen unit. We find that the earlier machines, which are still at work on farms worldwide, rely on outdated Windows CE versions, though the very latest screens run a Linux variant.

It’s one of these last screens to which he turns his attention, and we’re treated to an in-depth look at some of its secrets. After a lot of dead ends and learning exercises the final result is distilled into a pogo pin adapter for the hardware part, and a simple enough cron job to bypass one of Deere’s defenses by keeping the filesystem writable so a file can be updated. There’s a bit more detail about the special DOOM level too, as a special bonus.

You can see our original mention of this talk, or read some of our past Deere coverage.

Did You See A John Deere Tractor Cracked At DEF CON?

August 17, 2022 by 6 Comments

The Internet, or at least our corner of it,  has been abuzz over the last few days with the news of a DEF CON talk by [Sick.Codes] in which he demonstrated the jailbreaking of the console computer from a John Deere tractor. Sadly we are left to wait the lengthy time until the talk is made public, and for now the most substantive information we have comes from a couple of Tweets. The first comes from [Sick.Codes] himself and shows a game of DOOM with a suitably agricultural theme, while the second is by [Kyle Wiens] and reveals the tractor underpinnings relying on outdated and un-patched operating systems.

You might ask why this is important and more than just another “Will it run DOOM” moment. The answer will probably be clear to long-term readers, and is that Deere have become the poster child for improper use of DRM to lock owners into their servicing and deny farmers the right to repair. Thus any breaches in their armor are of great interest, because they have the potential to free farmers world-wide from this unjust situation. As we’ve reported before the efforts to circumvent this have relied on cracked versions of the programming software, so this potential jailbreak of the tractor itself could represent a new avenue.

As far as we’re aware, this has so far taken place on the console modules in the lab and not in the field on a real tractor. So we’re unsure as to whether the door has been opened into the tractor’s brain, or merely into its interface. But the knowledge of which outdated software can be found on the devices will we hope lead further to what known vulnerabilities may be present, and in turn to greater insights into the machinery.

Were you in the audience at DEF CON for this talk? We’d be curious to know more. Meanwhile the Tweet is embedded below the break, for a little bit of agricultural DOOM action.

For Once, The Long Arm Of John Deere Presses The Right Button

May 2, 2022 by 84 Comments

Over many years now we’ve covered right-to-repair stories, and among them has been a constant bête noire. The American farm machinery manufacturer John Deere whose instantly recognisable green and yellow tractors have reliably tilled the soil for over a century, have become the poster child for inappropriate use of DRM. It’s enough to make any farmer see red, but there’s a story from CNN which shows another side to manufacturer control. A Deere dealership in Melitopol, Ukraine, was looted by invading Russian forces, who took away an estimated $5m worth of farm machinery. The perfect crime perhaps, save for the Deere computer system being used to remotely disable them leaving the crooks with combine harvesters they can’t even start.

It makes for a good news story showing the Ukranians getting one over on the looters, and since on-farm thefts are a hot topic anywhere in the world it’s not entirely unexpected that Deere would have incorporated a kill-switch in their products. Recently we covered a look at how the relationship between motor vehicle owner and manufacturer is changing from one of product ownership to software licence, and this is evidently an example of the same thing in the world of machinery. It’s reported that the looters are seeking the help of tractor hackers, which may be unfortunate for them since the world’s go-to source for hacked Deere software is Ukraine. Perhaps they would be better remembering that Russia has legendary tractors of its own.

Thanks [Robert Piston] for the tip.

This John Deere Tractor Doesn’t Need A Driver

January 10, 2022 by 50 Comments

While most autonomous vehicles are meant to travel over the highway, John Deere’s new 8R tractor shown at the 2022 Consumer Electronics Show will likely only traverse fields and it will do so without a human at the wheel.

The tractor is slated to be available to farmers in late 2022 and has six pairs of stereo cameras to generate a 360 degree view of obstacles. It also uses location technology, including GPS, to ensure it is where it is supposed to be with a claimed accuracy of 1 inch. You can see a video about the beast below.
