I've always been a bit confused about the right to repair debate, especially as it concerns John Deere equipment. I don't own any "new" John Deere products, but I do have a few pieces circa ~2010. Perhaps my experience is out of date.

Here's how it's always worked for me:

1. A code comes up on the computer.

2. A. The problem is self evident. Or;

2. B. I search online and find the problem. Or;

2. C. I search online and find the diagnostics manual, which I use to find the problem. Then I have diagnostics manual pdf forever, and can use this in the future.

3. A. I search online and find the parts diagram. Or;

3. B. I search my dealers website and find the parts diagram.

4. I order the part.

5. I install the part.

Has something changed with newer equipment that prevents farmers from doing this?

Newer Deere equipment has a lot of components that have to be adapted using DSA - turbo actuators, various hydraulic sensors, various suspension leveling sensors, fuel injectors, interior displays, and anything SCR related are the big ones. Basically, any sensor that needs a calibration step or triggers an emissions code, or a few intentionally vehicle locked modules (ECM).

		Interesting. I just finished with a thorny hydraulics problem on a 9870 Combine. It turned out to be a faulty sensor. Part of my troubleshooting involved buying a new sensor, and swapping out each sensor in the system one by one with the new unit until I was sure they were all working correctly. No calibration needed. When i do need to calibrate a system i can do it all from the onboard computer. What a systemic downgrade in capabilities.

The parts have to be unlocked with like a DRM system to work.
