water in oil

Being antifreeze, it is a cracked block or head but most likely a head gasket issue which can be solved with a new gasket. Contined use of the tractor with antifreeze in the oil will result in significant damage to the bearings which can only be resolved with an engine rebuild, Hal.
 
I would suggest removing the valve cover and pan and do some investigating before any other disassembly.
Add a small amount of air pressure with a cooling system tester to a filled radiator and look for where the antifreeze is coming from.
I believe there is a soft plug in the front of the block behind the gear train front plate that could be rusted away causing the leak.
If the plug is leaking you should be able to see antifreeze dripping from the front main bearing. All engines may not have this plug.
If you disassemble first you have no way to test anything.
Good luck

Mark,

M heads are notorious for cracking. If the engine is in good condition otherwise, I would drain the antifreeze, replace with clean water, get a good stop-leak compound and follow directions carefully. Once sealed, drain the stop-leak and replace with antifreeze. We ran an M under a cotton picker (heavy loading for up to 12 hrs. per day and 30+ days per year and primary tillage with disc and pan plow)several years with antifreeze in it after using this method. If the engine ever boils, the stop-leak will likely NOT continue to hold. I would check the oil color and even loosen the drain plug frequently before starting. Maybe even every morning. Lot cheaper than an engine overhaul.
