need some help on what company is the best to find tractor parts, and which ones usually keep them in stock, also bought a tractor from a guy was told all oils were full, ready to run, come to find out not so, ran my tractor about 3 hours with about 4 quarts of oil in my trans. and low and behold, it stopped working. what kind of damage might have i done to it, i didnt hear any loud noise it just stopped moving forward, i drained the oil that was in it, found no metal, used a magnet to make sure there were no pieces laying around the bottom, is there anything i should be looking for. its an 801 ford. thanks for your help. twiggy
