Parts availability is a massive factor. When you break down mid-task, your task is often time sensitive. You can't always risk having your tractor stuck in the middle of a paddock for weeks while you get new parts in.

So, the reality of choice is pretty much down to what your local tractor seller/repairer supports, because they'll have the supply chain setup to cope with certain brands only.

The issue is that the tractor senses if you try to repair it yourself. There’s a trap mechanism which will punish you if you’re audacious enough to try to fix your machine.

Truth. Equipment is locked to the chassis SN and exchanging it throws a flag that requires a JD signoff to clear.
