Choosing an inexpensive used tractor for personal use, so far the choice has fallen on a CaseIH 685, model year 1987. I read reviews on specialized sites and looked at its specs at https://www.tractor-specs.net/case-ih/cih-685.html , it seems to be a reliable machine. What can you say? Maybe you have had a chance to use it? I found an ad for it for sale for $17,000.
