Seized 8n update

[Trz]

Been soaking the cylinders on this 8n for a couple weeks now and no progress. I took the starter off and prying on the ring gear it doesn’t budge. Took the exhaust manifold off and it looks pretty crusty in there. Trying to rock it in 4 gear also doesn’t budge. I’m thinking at this point I’ll go ahead and remove the head although I don’t know what that could revival. It will roll while in nueteral and it will roll while in gear with the clutch in. Although it won’t shift into 1st or 3rd gears. Is this for sure a seized engine or could I be overlooking something ? Do I have any other options now other than pulling the engine?

Any and all help will be appreciated as this is my first tractor and I was hoping I could get it running. It ran when parked 8 years ago.

Set in neutral, used a breaker bar and socket to the front bolt on the crank, see if it will turn, if it feels like your just tightening the bolt, it’s most likely seized up, barring starter isn’t seized.just went through this with mine, was rusted up and seized. Rebuilt it too to bottom.

Place the transmission in neutral.
Engage the PTO.
Remove spark plugs.
Place a 20" or 24" crescent wrench over the splines of the PTO output splines as if they are a bolt.
Wiggle the wrench and continue to tighten the jaws as tight as possible.
Get a 3 or 4 foot section of 1 x2 square tube to slide over the crescent wrench handle as a cheater bar.
Pretend you're King Kong on rotating the engine.
If something breaks, don't blame me....
