I would not buy something I can’t do at least some of my own fixes to.
Go to Youtube “Farming, fixing, fabricating” channel. They do all their own fixes on a large fleet of John Deere equipment. The only thing they don’t do is ECU diagnostics. Privateers can do those kind of diagnostics too but you need the skills to go along with the equipment. Few people posses that.
P.S. The implications of this decision go beyond fixing tractors.
