Are there any other signs of overheat other
than temp gauge?? i would expect to see a lower
level of fluid in the radiator, and possibly
marks left from fluid leaking from the rad
cap...

It would be worth taking a on contact
thermometer and checking the temperature of the
engine when the gauge says it's hot, there is a
chance the gauge/sender is not accurate, might
be worth removing the sender and making sure
the ground is good (no tread tape etc)
 
Is the radiator water level down?? Your moisture COULD be condensation. Since you have not ran the tractor since October. I would change the oil and run it and see if you still have milky oil after that. Also check to see if you have any bubbles coming up into the radiator. A bad head gasket can do that. While your running it check the temperature with some thing other than the factory gauge. I have had them go bad. I usually use a inferred thermometer. IF your sure it is getting hot and there is water. I would pull the head and have it checked. The water leak could be many things but the getting hot is usually head or head gasket issues allowing combustion gas into the water.
 
They rarely blow a head gasket,, my bet is a pit in a liner...
You will get the same result...
