The other thing about tractors is that the three point hitches, PTOs, etc etc, have been standardized forever, so there's very little lock in in terms of, swap out your JD for and IH and away you go, so I'm curious if eg modern seed drills have any fancy tech which locks you in.
Technically there are standards, but you know how that goes in the real world... Funnily enough, a friend bought a new tractor and planter, both from John Deere, and they weren't even compatible with each other. The tractor needed to have the cab removed to install the necessary hardware (ethernet) to be compatible with the planter.

Hydraulic hose couplers didn't find common adoption until the mid-80s/early-90s, which is surprisingly late.
