IR thermometers aren't very accurate unless they are calibrated to the object emissivity. Read the instructions for it. If the emissivity can't be calibrated/adjusted, the temperature is probably wrong.
Also, the leak could be from the radiator cap. Most have a pressure relief spring under it and the radiator will have an overflow tube coming from the radiator neck. Take the cap off when it cool. Check the level of the radiator. If it's down, and it has a relief cap, the cap is probably bad. If it has a newer system which includes the expansion tank only, the pressure relief cap and overflow tube will be at the expansion tank. Those go bad too but, in both cases, the caps must be on tight.
For sure, your tractor is either eating coolant (blown head gasket) or it's leaking out.
