1420 Cylinder stopper, seems locked

Will not turn, gear box in high or low, has no effect on it, try shifting from N to H or L with threshing engaged and it is like trying to shift a tractor with out using clutch. Grinds gears as it should, It IS shifting into gear, but the cylinder is not turning, Any one have any ideas what it could be, a splined shart sheared, are there shear bolts in the driven shafts? The big pulley and belts all turn as should, but from the driven gearbox pulley, to the rotor, something is broke. Where do I start.
 
On back of the rotor there is a hub that bolts on to it with splines that run on the gear box shaft. Im betting the bolt sheared off. To fix it you will have to pull feeder house and pull rotor out from cage enough to get to it. There are bushings in this hub also that should be replaced when you pull it out.
 
Can you roll the rotor round with a bar when the gearbox is in gear? It sounds like the bolts broken in the coupling. But I had a similar problem with a 1680 and it was the gearbox. Mine would grind when you tried to engage high or low, but wouldn't hold in either gear as soon as the rotor moved about half a turn. Ended up changing the 2 speed gearbox. When you pull it out the coupling is right there. I'm not sure if I'd pull the rotor as Mike says or pull the gearbox. Pushing the rotor back up there and lining up the splines might be a bit of a challenge.
 
When you say the cylinder is locked are you meaning you can't roll the rotor around even when the gearbox is in neutral? If the rotor is locked, then it sounds like you have something jammed up in there or maybe bearing collapsed?
