Engine Problem

Ok Guys. I have a 1948 John Deere B and it was running and I pulled it on my trailer to haul it. It run like it always does, not a problem. I chained it down and transported it. When I got home I unchained it and went to start it. The starter engaged and that was it. The starter is free and away from the flywheeland I can't even turn the flywheel. I tried different options like pulling the spark plugs and no gas in the cylinder walls. I did pull the top plate off to look into the engine and I tried to move the pistion crank, on the flywheel side I can move it but on the clutch side I can't move it. Did that pistion cease up? Like I said it was running fine before this. I'm hoping that I don't have to tear down the engine. Any ideas or suggesting would be a great help. This is the first 1948 I've owned. Thanks for any suggections or ideas.
 
If the plugs are out and the starter is not engaged there be no compression. You should be able to turn the flywheel by hand.Something on the clutch side may have broken while transporting if the clutch was engaged. If it ran fine going on the trailer and shut down normal I don't think it is the engine being seized. Sounds to me like a bearing on the crank or something on the clutch side. Hope this helps.
 
Does this engine happen to have those compression boosting inserts that are installed above the pistons? If so the right one might have moved down the cylinder and is now jammed in there by carbon not allowing number two piston to move. Sort of locked at TDC by all the torque it's under. The only guess I can come up with and it's a wild one for sure. Or maybe it's a valve that lost it's keepers and dropped into the cylinder? Valve cover off would show that one real quick.
