Check the shear bolts on the auger shaft if it is a two stage. A single stage may have a broken belt.

Thank you! I checked the shear bolts and they were fine, but took off the belt cover and separated the machine, found a broken belt and lots of mice nests! Wish me luck putting it back together today. The only thing that puzzles me is how to the rear belt off whjen there is a housing in the way. It says to "push pulley to the left" but doesn't deal with housing in front of it. Hopefully I can figure it out.
