About the only way water can get into oil other than from cooling system is from open exhaust when tractor is left out in rain. The rain goes down through exhaust, through an open exhaust valve and into cylinder and slowly leaks through rings. I doubt this is your problem. If water gets into the crankcase it will not turn oil milky untill the engine is run. The water or antifreeze will settle to the bottom of the pan untill engine is run or it is drained out. Sometimes if there is enough water in there it will settle out over time after the tractor is run,to the bottom of the pan again. If I was you I would drain oil only if it is milky. Then put the plug back in. If oil is not milky I would simply leave tractor sit for awhile and add pressure with compressed air and a special radiator cap to the cooling system. Somtimes a cracked head or block or a bad headgasket will only leak while cooling system is under pressure when engine is warm. Then wait a day or two then (if oil is still in crankcase) just unscrew oil drain plug untill liquid starts to drip. If the oil has been drained ahead of all this you can take the drain plug clear out. If antifreeze or water comes out you know that you got a bad head gasket or cracked head or block. Do not run tractor while going through this procedure becuase the engine will just try to mix the oil and water together. If tractor is not run the laws of physics will let the water and oil seperate leaving the water at the bottom of pan right on top of the drain plug. If you do find that there is antifreeze or water whichever is in radiator you will have to tear engine down to see just where it is coming from. If there is no water or antifreeze it may just be that the engine has not had oil changes according to specifications and may just take a few oil changes to clean the old engine up inside. If oil changing has been abused just simply changing the oil one time is not going to clean all the puke and grim out of the engine by just draining existing oil. This puke and grim all over inside the engine will just make new oil look puky and grimmy in a short while. You said you just bought the tractor so it might be the owner knew what was really going on and just past on the problem. I bet you'll find that you will have to tear the engine down but I hope I am wrong and you find no coolant leaks. I hope this helps you.
