There is a lot of misinformation about this. At face value, articles like this imply you're not able or allowed to fix mechanical issues, how dare they! What they don't mention is that manufacturers protect their electronic gear i.e. the consoles inside the machine that use GPS to run a field, adjust the attachment acccording to various sensors etc. This is very sophisticated stuff, and farmers need and want this fun…
It’s one thing to say oh only the new stuff is locked down, but every part of the vehicle is, something that wasn’t the case a short while ago. In fact they’re digitizing controls and simple mechanical functionality that doesnt need to be digitized so they can abuse their maintenance monopoly.
