Re: Tractor keep overheating not the radiator just had it...
As Colin said, could be the head gasket. Overheating is a tell tale sign of it, replacing it can cost a lot of money as well. www.steelseal.co.uk is an affordable alternative !

thermostat or clogged radiator you would see the water pump leaking go to the water pump and try to move the pulley back and forth take the belt off and check for free turning no grinding I'm pretty sure the thermostat's closed but the belt could be slipping to so check the tension on it if its to loose it will slip and not rotate the water pump pulley at the proper rpm's
have you flushed out block to make sure that block is clean ?do the same for radiator, replace thermostat and make sure its installed correctly ,not backwards , if that works for the overheating ,it might answer the cutting out
If the overheating is only occasional, it sounds like the radiator still has some blockage that moves around and plugs up again. Try flushing it backwards again. If it continues, consider a new radiator. A radiator is cheaper than head gasket work, which may happen if it keeps overheating.
There is no adjustment on the cooling fan. If the car overheats, there are only a few things it could be. First, with the engine off and cool, check if the radiator is full of coolant and it looks clean.
The most likely cause of overheating is a stuck thermostat. You will need to drain the coolant and replace the thermostat. You can locate it easily by following the top radiator hose to the housing on the engine. The thermostat is under this housing.
You could also have some kind of blockage on your radiator. If there is a lot of dirt in the fins, air cannot circulate and remove the heat. Use some compressed air to blow the fins clean.
1 Check if the radiator fan is working properly.
2 Check the level of coolant in the radiator. If less top it up.
3Check the oil level. May be the oil is less. If so top it up.
4 Check the water hoses are connected properly and there is no leakage at the connecting points.
5Get the fins at the radiator cleaned up to allow free flow of air.
6 If all this OK and the car is still getting overheated then either the water circulation pump or the oil pump is not functioning.
A bad head gasket will sometimes cause air to bubble into the coolant system. If it bubbles over when you start the engine (cold), then there is probably a bad head gasket.
If the usual things (thermostat, coolant level, clean the bugs out of the radiator, coolant flush) don't fix it, then the radiator could be bad with calcium or corrosion deposits.
