Bought a nice 49 G from man that owned it for 55 years. He stated that there was no antifreeze in it and he hoped the head gasket was OK as it sat for some time without water / antifreeze. I drained the water and, although it looked like more, maybe a less than an eighth pint of oil drained out last. Haven't dropped the oil yet. He said the oil had been in the tractor a long time, but not many hours. So more than likely it will have condensation which would be hard to tell from coolant water. Manual says 12 7/8 gallon cooling capacity and that's about what came out of it. Any suggestions would be appreciated.
