Thanks for the reply. :thumbsup: When I got the tractor, the owner said that he had just changed the oil's. When I pull the dip sticks, the oil looks clean and clear (for oil), so I'm going to say they have been changed. He did say the PTO had 90 weight. Good to know the amount in the PTO, as I had no idea, as with the engine. Since John Deere used and from what I understand, still does use the Yanmar Diesel, I should be able to find that out. Want to add Sea Foam to the oil and fuel pretty soon. So will look at doing that. Man, I love this tractor. I'm finding myself trying to find things to do with it. What an addiction! :laughing:
