This is really a non-issue. These tractors are now controlled by computers to the point it would cost thousands of dollars in equipment and training to be able to work on them to alter the software.

If an owner were to change the software to increase Hp or alter emissions it would void the warranty just like it did years ago when someone cut the lock on the injector pump to increase Hp.

Yes, the law now says you can work on it. How are you going to do that when the manufacturer refuses to provide the training or computer interface to non-dealers?

I’m a retired engineer that worked on tractors (not Deere) so I do know a bit about these systems.

Error happened. 1
