The tractor starts, but the belt is squealing since the fan is not turning. I cannot spin the fan by hand, what's wrong? Can I free it up somehow or is this a BIG problem?
It is likely a big problem, or going to cause one, if you try to run the tractor for very long. Almost certainly, the trouble is the water pump has seized due to corrosion, so is not spinning while the engine turns. Obviously, without a functional water pump, the tractor will rapidly overheat, with severe damage imminent.
The water pump can be rebuilt or replaced; I have done both on some of my tractors.
