Just got a YM 2000 from a Customer whose Husband passed away. The tractor had been sitting for a while but only has 82 hours on it. We replaced the battery, and cables, changed the fluids but after running for a short while it runs hot. I had one of my guys flush the radiator but it is still doing it. If it was the water pump, it would very quickly run hot, wouldn't it? Does anyone have a suggestion what to look at or what it might be? Does anyone have one of these tractors and what success have you had with it? It seems like a strong little tractor. Thanks.
