I posted on the JD forum down below about buying a JD 630 at the auction. I was uncertain about what I should do with it as it had been sitting for a few years and I was guessing that it was stuck. The posters on that site advised me that they were desirable tractors and highly sought after by JD collectors. With that in mind I decided not to sell it but give it to myself for a Christmas present Well, today I found out it was stuck for sure. So I enlisted the help of my wife and took the challenge to get it turning over.
I decided to use the hydraulic pressure method as that usually works on tractors that are stuck from sitting as opposed to those rusted tight by water entering the engine from rain and etc. First I removed both spark plugs and put a hydraulic fitting into the one of the spark plug holes. It took me a while to locate all of the hydraulic fittings that I needed because I had not had to free up an engine for a while.
Finally, with all my fittings located, I began the process of turning the engine. Now with the hydraulic adapter screwed into one of the spark plug holes and with my wife watching for movement, I applied hydraulic pressure to the piston.
My wife reported that nothing happened, nothing moved so on to the other side of the engine and change everything to the other plug. Try again and, "it moved" my wife announced. We had the engine make a full half turn with oil squirting out of the plug opening on the other side.
I have used this method to free stuck engine many times and it usually works if the engine is not badly seized. Sometimes I have had to tear the engine apart after it was freed because of rust damage but even then it was a much easier job since the cylinder walls are already lubricated from the hydraulic oil used to free the engine.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
