Do you see any bubbles in the radiator when the engine is at an idle? Could be the head gasket. These engines are very easy to rebuild if it needs it. A good manual will walk you through it. Your engine has wet sleeves so your engine block shouldn't need any machining.
If I was going to rebuild it I would pull the engine. It's not that hard the manual has it down step by step. I would drain the radiator and oil pan and pull both of them. I would also pull the head. Then block up the drawbar so the tractor doesn't tilt backwards. Then use a chain hoist after rolling out the front wheels to lift the engine. Take pictures and notes during the teardown. Separate the parts and use a cardboard box. Mark the box where the parts were removed. Keep the rocker arms and bolts together in one box, head bolts or nuts in another same for the oil pan. Put the bolts you remove in another box you removed when unbolting the engine. Sleeve kits are available off this forum. Take the head and crankshaft to your local auto machine shop. Have them do a valve job and magnafluxed the head. Take along the crankshaft and have it measured for wear and buy your bearings from them. Check your clutch disc for wear. Get it relined if it's down or near the rivets. Have them install the old connecting rods to your new pistons. Clean that block area where the old seals are installed that seal your wet sleeves. You will need to drive out the old sleeves after removing the old pistons. Do one piston at a time and reinstall the rod cap back on the connecting rod once the piston is out. The caps and rods have numbers have them facing the same way and the numbers face the camshaft. Hal

Looking around at my new neighbors, most of whom are city raised and have recently acquired their first mini-farms of five to fifteen acres and also from reading questions ask at various discussion sites on the web it is frighteningly apparent that a great many guys (and a few gals) are learning by trial and error and mostly error how to use a very dangerous piece of farm equipment. It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
