Joe: gene and Scotty have given you some very good advice, and like gene, I'm assuming you know very little of the past history.
To add to what has been already said, do you see any evidence of anti-freeze or coolant in the crankcase? Oil in the radiator will not have any adverse effect, however anti-freeze in the crankcase will. It will destroy the crank and rod bearings quite quickly, plus do significant damage to the crank. My guess is 95% of all cranks ever requiring turning and machining was brought on by anti-freeze in the crankcase.
Having said that, I'd drain both liquids, look them over very closely. Anti-freeze in oil will make it sticky when you rub it between your fingers. Oil alone should be quite slippery. If you find pure oil from crankcase, fill crank case and radiator with fresh clean liquids, carry on and watch both closely as you use the tractor. If your getting one way movement of liquid from crankcase to radiator, you should see bubbles in the radiator after tractor is warmed up. Then and only then I'd go looking for a cracked head, cracked block or bad head gasket.
On the other hand if you find coolant in the crankcase oil, you best get the wrenches out PDQ.
