Tractors are durable goods. They are not replaced often. Becoming the Kirkland brand of tractors means taking a major hit to sales for years in the hopes that it comes back to you in decades. It means betting the entire tractor business on this, essentially.

You'll notice there are no Kirkland brand furnaces.

Knowing nothing about tractors, but there always was a strong push from vendors to not allow repairs by the user.

In the olden days it would be weird shaped screws and stickers with "warranty void" kind of bright red wording everywhere that would impact their bottom line. Then potential denial of repair or extra costs ("out of warranty") if they could find any plausible reason to attribute the issue to your intervention where you shouldn't touch.

I'd see the introduction of DRM as a way to enforce rules that were already there, more than a radical change to their business model.

So yes, I'd expect a lot of resistance to moving to right of repair.

Voiding a warranty for DIY repairs is very different from making DIY repairs impossible.
