4110 gas locked up

[theruffneck]

So this was weird. I was mowing, my wife called so i turned it off. Finished my convo, tried to start it again, and nothing. I checked the starter, it did what starters do. I checked the oil, altho its a little low, its still on the dipstick. I just put a 3 ft breaker bar and socket on it. She didnt budge. Im thinking ill jack it up, and use the transmission to try to free it. Anything i should check before? Its a 3 cyl gas tractor, 4110.

Check your bank account before trying to free it using the transmission!! JMHO

Starter did what starters do??? Starters turn the engine so it will start, when you used the starter did it just clunk? I'd be removing spark plugs at the least and then use the socket/breaker bar again.
Some learn the hard way but a hydro locked engine can actually bend connecting rods if you apply enough pressure trying to turn it over. I gained experience from others failures, a lot cheaper that way.
