I've had good ones. The air cooled tractors were not liked very well. I have a small air cooled 250 that has taken thousands of hours of abuse with no real parts use, just two clutches. But, it is a rough machine. The large water cooled tractors are better and I do like them. My local dealer sold over 10,000 of them in my area.
I have never had the parts problem. You can order directly from Belarus if you need to. My local dealer stocks the common parts. I've never had one break down more than any other old tech tractor. They make a great back up tractor and the prices are rock bottom. Major parts could take time, but you probably could just buy a "parts tractor" for very little. Around here, you have to pay cash, they have hardly no resale value after the importer went belly up. The Koreans are replacing the Russians, I wonder if they will have more staying power.
