That's a really weird way to spell "incumbency and network effects".

In fairness, you're not wrong, but that seems to be a very specific framing that hides a lot of what this whole discussion is about.

It is more than that. It is also the dealer has the parts you need, even for older stuff. Deere is well known to stock replacement parts longer than anyone else, and can get replacement parts where others would say not possible. network effects and incumbency help as well, but Deere is the most repairable.
