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.
