Just posting this for everyone to get a kick out of. My Wife and I were combining corn this PM when I took a quick turn on an end. All of the sudden the combine got to shaking like I thru a chopper knife, I wasn't sure that was it so I got my Wife in the cab to turn the machine on while I did a walk around and it was the chopper. Vibrating and the belt was jumping. Turned off the darn thing to check for a missing blade and they were all there. So we decided to loosen the drive belt and take it off to turn the rotor by hand, well I got the belt off and there was a piece of cob lodged in the pulley. That darn thing musta' had eyes to get in there.
