I have an 8 hp Yard Machine Snowblower. It is about 10 years old. I'm in Burlington, Vermont (33 inches yesterday) and just started blowing my walk which has small "pea stones". The snowblower suddenly stopped throwing snow. I shut off the machine and noticed that I had broken one of the shear bolts on the auger. After fixing this, the inside wheel (auger that shoots out the snow?) continued to turn freely, without any friction and would not engage the auger to make it turn. I then pulled out the auger which is attached to the inner wheel (auger). Now I have no idea what to do. The snowblower still starts but the auger(s) won't turn. Any help would be appreciated. Thank you.
