I have a craftsman snowblower (10hp). The outer blades turn fine (cotter pins look fine). My two inner sets of blades do not. I did remove a piece of wood that I must have picked up. It is now clear but still does not turn. Thoughts?

Hi,
Shear pins or soft bolts used as shear pins are used for attachment purposes. They are meant to be the weak points and to shear to prevent damage to another component.
