The blade shaft and pulley all stop. So I called Amazon and they gave me a refund for it so I ordered a new one which will be here Saturday. So I'm going to replace it and see what happens. I spent hours trying to get it to work so I feel like something isn't right because the other one just bolted on with no issues after I put it together. I took the whole thing apart and didn't see anything but who knows.maybe the blade attachment is hitting something. There's resistance on the shaft when I tighten the blade. And if I tighten to much it locks it in place I'll just keep it to have as a parts spindle I guess.
