If you have it in neutral, will it roll freely if pushed - confirms transmission/ drivetrain not locked up (hard to do if loader is down!).
Still in neutral, can you turn the crankshaft from the front of the engine using a breaker bar and socket - confirms engine not locked up.
Can't really roll it but jacked up rear end and everything spin in gear and out. Can not turn engine manually.

does it have a clutch? if you engage does the motor then spin?

I pulled starter, and injectors. Started fine in the morning to raise bucket and ran great the whole day prior.

yea buddy i got nothing for you, if the clutch is in, and the pto's are off, starter is pulled and injectors pulled. you have some sort of mechanical problem, drain oil see if you have metal. I can't think of anything else, is the hydro chain? maybe break a hydro line open

Only a couple things that I know of that will lock an engine besides a transmission issue which can be eliminated by pushing in the clutch or putting in neutral aid that is a dropped valve, hydrolocked engine or ran it out of oil and spun a bearing.

Have you ever had the overhead adjusted. I believe Kubota recommend every 1000 hours or so. Pull the valve cover and have a look-see at the valves.
