There should be a three digit hour meter on the dash of the YM1500. It will most likely show 600-800 hrs which is common for an early 80's Yanmar (I assume it's gray market) if it shows less than 300 hrs it may have rolled over already, but that should not worry you. Even after 1000 hrs these Yanmar tractors are just broken in good and should last for many more years. I have not any trouble with my 1300D. I have been using it for at least 5 years for mowing and tilling and have never had a single problem. I have no trouble finding parts. I order parts from Hoye Tractor and they seem to have every part imaginable, although I have only ordered a gas cap, fuel filters and a light bulb. They also carry user manuals for Yanmar tractors.
