Auger won't engage

Hey everyone,

I've got an old model (not sure of the year or SN) Simplicity snowblower with a 7HP briggs and stratton engine on it. This year after our first big snowfall the auger decided to stop engaging on me. I've checked the shear pins and the cotter pins, and they are all in tact. I'm pretty lost on my snowblower. I'm not very handy but I am willing to learn. Can anyone give me advice? First I'd like to know how to disassemble the front end and check inside to see whats going on there. What do I do?

When it's running and you engage the handle does the impeller spin but not the auger or are both "dead" ??

If neither than maybe the belt or the tensioner.
If the impeller is spinning but not the auger than it's the gearbox in the center of the auger

.
Make sure the windows are up before the snow plow goes by !!

The first thing you should check then is the belt and tensioner. Remove the belt cover and inspect, the belt may too worn or broken.

Well, I think I found my problem. Is there any other reason this thing might fray or cut like this either than the belt just being old? What should i look for?

Unplug your spark plug. Reach down and fidget that belt off. Look down or to the side on that bigger pulley for a brake or something that looks like it's wedged against that pulley (a brake arm from a spring or idler bracket). Usually spring loaded so may have to pry and secure somehow away from the pulley. Then try to turn the pulley toward the camera angle. It should spin by hand, and see the augers rotate (although not a one to one ratio as you turn the pulley, the augers should rotate forward from top to bottom as you rotate the pulley). If it does not, the impeller bearing/shaft is seized or the auger gearbox internals broke and jammed the situation to a stop. If all good and you see rotation corresponding to the auger from the pulley in picture, just replace the belt. From the looks, I'm guessing the front stopped for one of the reasons I suggested above. Bad belts don't usually stop on top of the engine pulley and burn through, they let go and snap.

Everything spins pretty good. I'm kinda worried about all that black dust all over the place. That has to be a sign of something.. Should I just get a new belt, install it and hope for the best, or look for a different problem?
