Ariens ST824 - 924082 - Nothing Turning

All, Thanks in advance for your time and any help.
Was out in more than 24" of snow yesterday. Broke a shear pin, no problem, had most of the job done, thank God, when something got sucked up by the auger. After that, the auger, shaft, and impeller will not turn.
Never fails. Before the storm I always clear the sidewalk of junk and potential hazards. Just too much wind the other day though.
She still runs and drives - forward and reverse is fine.
Checked the shear pins, removed them, and re-installed, and they were fine. Still, there is no way to spin the auger or the impeller.
I popped off the cover for the belts - one seems fine but the, larger, with the tensioner, seems loose. It is still on and around the pulley, however, when the handle is engaged, it is still a bit loose for my liking.
Has anyone a suspicion or place to start? I would really hate to take it down before determining just belts?
Has anyone a procedure for troubleshooting?
FWIW - it's a Tecumseh.

You don't want anything engaged and as stated you should probably pull the spark plug wire just in case. What we are trying to do is determine if the impeller shaft is turning like it should be. You should be able to turn it either way with a little bit of drag felt from the auger brake. If it does not turn you can try pushing the auger handle down 1/4 to 1/2 way to relieve the tension on the brake without fully engaging the belt and see if that helps. When you push the auger handle it pivots an arm. On one end of the arm is a wheel that pushes the belt tight. On the other end is a brake pad and spring. When the arm is pivoted one way the belt pushes tight against the pulleys, when it is pivoted the other way the spring pulls the brake pad against the bottom of the pulley.

Back again.
I believe I have all of the terminology down right. I am looking at the pdf for the Ariens 924 Sno Thro. It does not list my exact model (924082) but it looks close. Hopefully, the parts are known by the same name.
As expected, the pulley closest to the engine rotates with a pull of the chord.
As expected, the pulley on the impeller side, does not rotate - either with the clutch down or not.
The impeller does not want to rotate. I tried the 2x4 with a hammer and was able to muscle her through 90 degrees. Very difficult.
I have looked everywhere and there does not appear to be anything obviously obstructing its rotation. However, I am unable to see a good portion of what's behind the impeller.
Facing the impeller, from the auger side (opposite that of the operator), there is no way to visibly inspect if there is anything behind the impeller from about the 6:00 - 12:00 position.
I tried reaching down to rotate the large pulley, with and without clutch - nothing.
Worm shaft will not rotate and neither will the auger shaft.
Finally, I did see some debris, likely from a rock. Also, fresh scratches on the impeller housing.
Ideas?

No Luck, nothing behind the impeller.
Could there be something jammed in the gear case? Causing the impeller, worm, and auger shaft to all not turn?
What would be your next move?

What would be your next move? I have read a couple reports of roll pins falling out or breaking inside the gear gase. If it fell out I could see it jamming, but if something else was stuck I would think you would have some wiggle in it. At this point I guess you have to start taking everything apart and checking everything until something fails to turn. To check the gearbox you have to get the pulley off the impeller and remove the whole assembly from the housing. One other thing to check would be the bearing behind the impeller. ---- You might be able to remove the oil fill plug and look inside with a flashlight.
