If you're a US company the vagueness of emissions law likely prevents a US company from hazarding doing it and instead locking down the repair of their power trains to ensure emission compliance. Korean companies get away with it because they don't give much a shit if they're banned from import, it can always be washed through another foreign company. John Deere can't try that sort of thing since being a household-name US company is their bread and butter for commanding a premium in the first place.

Everyone is doing it on the import tractors with the screws. They are not doing it with John Deere tractors, which are locked down for emission compliance. John Deere is handicapped by the fact they're located in the US and regulators have more leverage on them to prevent the sort of right-to-repair which would enable emission bypassing.

>Do what? What is not happening today that you think would happen if people were given the right to repair?

What is happening today is people with John Deere are not able to unlock their tractor for repair and turn the "screw" like they can with import tractors. The very first thing they will do once they can "repair" is delete emissions controls. That's a big part of what the farmers were pissed about and why they wanted right to repair, they couldn't "repair" their tractor to not use DPF, etc on their domestic tractors.

Do what? What is not happening today that you think would happen if people were given the right to repair?

You pretty clearly said everyone is currently bypassing this, otherwise companies would not be putting in larger engines. Is that wrong?
