Toro 421 Snowblower - Both Augers Not Spinning

With Utah's latest storm today, I got out the old Toro 421 to clear the several inches we had received over the last few hours.

Without warning one of the two augers, that feed into the second stage, stopped spinning...and now spins freely.

I'd like to order the part to get this fixed ASAP but am unsure as to which part, exactly, is causing the issue.

Anyone have experience with this or know enough to tell me?

That's the closest diagram I could find to my model.

The parts you need are # 34 - shear bolt and # 35 - nut for bolt.

For some reason the part # 34 is not listed in the parts listing.

If your augers just spin on the front shaft.....then the shear bolt is what you need. You should see a cutout in the auger.....towards the outside.....the bolt is in there.

Dead on PJmax.

The bolt on the outside of the auger was entirely missing...does this also mean bolt 34 is also missing? I'm not sure what this part does, exactly. I can easily replace the outer bolt, any idea what size bolt it would be?

They are basically 1/4" bolts BUT you want them of a certain metal so that they shear (break) if augers get jammed. Those bolts should be available at any local small engine parts or service place. A common part.
