B2782B Snow Blower shaft and sprocket.

The key is there and raised enough to be in the way. Yes, the sprocket has about a 1/4 inch of movement between pushed all the way back and abutting the key. Thank you for the link.I don’t see any key way in the hub. The key in the shaft looks like it is there just to fill the shaft key way.
Do you have the hub loose from the sprocket? Here is a link to an instruction manual for a similar product. I would not worry about getting the key out now and see if the hub will just slide off.

Is there some room for the sprocket to move back towards the snow blower?

hmm, 'move', as in AWAY( back) from the bushing ?
If so, great ! it's just the bushing 'friction' stuck on the shaft.
You might be able to use a 'puller' to get bushing off, even a chain securely bolted to it, a 'slap' puller
but if the bushing key isn't 100%
I don't see ANY 'keyway' in that bushing, especially compared to the posted picture in #9 (?) or the one in my hand. Maybe it's a 'trick of the lighting' but keyways are usually 1/8- 3/16 'tall'.

If you wanted to buy a replacement bushing, I believe this should fit. Verify the measurements before purchasing.

It doesn't look like Kubota sells the bushing by itself, only the combo with the sprocket.

Yes, that resembles what I have. Thanks. I already have the replacement kit coming tomorrow which includes the bushing (hub). The most difficult aspect of the repair so far is getting that key out of the keyway. I am still working on that.If you wanted to buy a replacement bushing, I believe this should fit.

The keyway is in the shaft, which is keeping me from pulling the bushing off.

OK, all I have is that picture you posted in #5 and it clearly shows the key is NOT in the keyway of the bushing. I'm betting if you took a picture of the 'bottom' side, you'll see a notch ( keyway) in the bushing.
Also keys are normally 50/50 into both keyways(shaft and sprocke/gear), yet yours is just a bit out of the shaft's keyway.
if you could get your head 'around back', you should see the keyway of the sprocket, that's supposed to be over the shaft keyway.
My gut's telling me, wrong key and somehow sprocket rotated relative to the shaft (remember key is supposed to 'lock' both parts in 'sync'. 2 mor epictures would be nice...
Grab a grinder and remove the visible key. It's OK to ,oopsy, grind a bit off that shaft as it's not being used in that area. If it has rotated as I suspect, YES, it will be a 'bear' to remove. 'slap hammer' to shock it will work,BTDT.

You need to rotate the hub or the shaft to make the key line up with the keyway.
Then you are still very likely going to need to use a puller to get the hub off.
If you can get a 2 or three jaw puller to grab behind the hub that's great if not use a steering wheel puller to get it off.

yeah it'll be a bear', (saw the newer pictures...), it did rotate.
even when you line them up, there'll be enough 'junk' to make life miserable.
sine the key is 'history' anyway, grind it down flush with shaft. Those bushings are presise made so even A 1/2 thou will 'bind' it up.
2-3 more posts and we'll see a 'tada' picture !!
