Farmers are still buying Deere equipment for a lot of reasons, including the fact that Deere has by far the best service network during planting and harvest seasons. You will have the least likelihood of disastrous downtime with Deere equipment. Forcing you to get service from the service network makes sure that the service network continues to exist.
It's a complicated situation. (I support right to repair, btw)
Which doesn't actually mean they aren't screwing people over. Personally, I don't know if they are or not -- I'm not a farmer, and I don't know what all the issues specific to farmers are.
But the arguments that JD are making are ones that are bad for everyone outside of the farm equipment business. In that sense, they're helping to screw all of us over.
Then what? We probably see higher volatility due to an increase in crop failures, but maybe lower average food prices overall.
Having exclusive ability to repair their tractors does not make it easier for John Deere to stock that inventory. It makes it more profitable for them to stock that inventory, because they know they can sell it. That profit allows them to tighten their margins elsewhere, and to expand their belt elsewhere, but it does not fundamentally change the actual repair. It does make it easier in some ways that they can exploit supply and demand and economies of scale.
There are other ways that John Deere can enforce said Monopoly. They can sign contracts. Maintenance contracts are very common in this space, stating that you will only do business with John deere. That's not an unreasonable thing to do. I am a okay if every farmer wants to sign that contract with John Deere. If John Deere were to make that part of every purchase, at least it would be understood that it were part of every purchase, that you could not buy John Deere tractors without buying their service contracts, and how that interacts with existing antitrust law is a separate problem. One that has been discussed to death and will continue to be.
That's weird, cars get by just fine on having mechanics in every town.
They can more than afford to offer a high level of service at harvest time without ripping off their customers and screwing over everyone else as well by opposing our right to repair.
As it stands their current level of service isn't even that great. Farmers have been complaining about not being able to get parts (https://talk.newagtalk.com/forums/thread-view.asp?tid=104450...) and saying that because they're forced to get repairs from John Deere that single source for service gets overwhelmed and they can end up waiting for weeks on technicians while watching their crops rot away.

There's no difference between having a capacitor replaced or EEPROM reflashed by someone wearing a green shirt and not. If the fault is gone, it's gone. Publishing the tools to validate repair would alleviate the pressure on JD's service network.
So is the changing market dynamic is that John Deere now sells shitty tractors which means they have to depend on DRM and forcing people to get repairs through them in order to be profitable?
I suspect the reason so many companies resort to user-hostile anti-competitive practices is simply greed and a willingness to screw over anyone to make an extra buck at any cost. They want to have ever growing profits and growth which means they have to come up with more and more ways to take our money.
