Check those nuts and bolts.

I was snow blowing this morning and my buhler/Farmking 740 started to make a noise. Sounded like something was getting banged around in the auger. I couldn't find and thing like a rock/ice. started to check for loose bolts and such and touched the main fan bolt and it came out in my hand! I think that would have been a major mess if it got loose before I found it.
