I am looking at a YM 2500 Yanmar tractor for my first tractor. The tractor was bought in Liberty, MS from Liberty tractor. The man selling it says they completely refurbished the tractor (new seals, clutch and tires and the such not to mention a new paint job). It does appear that way, there are no oil leaks, the steering seems to be tight and everything appears to be in good shape. It comes with a KingKutter finish mower and he wants $5,000 for it. Its serial number is 06079 and the diesel engine 3-cylinder is a 3T80. Does anyone have one of these? Any problems I need to watch out for? Problems with parts availability? How about a manual on this model where can I get one if I buy this tractor? Can any one tell me how old this tractor is (1977 ?)by the serial number? or any other information?
