B2150 4x4, motor won't turn

[pgarber901]

Need some help/ ideas. Kubota 2150 ran great yesterday. Started fine this morning. Raised loader so I could remove some brackets for the mower deck. I finished up and the loader had drifted down a little( which I expect) and then I lowered it all the way down while tractor was off. I went to start it later and it won't turn over , only got a partial revolution, so I thought being cold it needed a charge. Well 3 hours later it still won't turn , starter engages and tries but can't. Starter is fine. Any ideas ??????
Before I get these answers I got from another site , starter , battery, the wires and connections are good ! It's not electrical ! Also I moved the loader controls around in every correction to relieve any pressure.

I know you say the battery is good and that you charged it, but if it were me, I'd try a different battery before you do anything else (maybe pull the one out of your vehicle just to test it). Always try the simple stuff first.

Way past the simple stuff.

Measure your battery voltage. With the voltmeter still connected try the starter. The battery should be about 12.6 volts initially. If it drops below, say, ten volts it's time for a new battery. If the voltage is indeed good check the voltage getting to the starter.

IT'S NOT THE BATTERY!!!! Engine won't turn over even by hand . Ran it the whole day before. No issues , no problems, no excessive smoke , all fluids good.

All fluids are good.

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.
