Were all the paddles still in placeIJ Any bolts missing or threads pulled right out. You may find the evedence laying on grain pan in front of chaffer. Had to be something more major or paddle falling off. Good luck
If you still have the old style acc. rolls with the tire carcus material you may have a shaft that is broke internally.You have probably found the problem by now,but wanted you to be aware of this. New style acc. rolls have bolt on flutes and the old style is a stack of rubber material stacked onto a shaft. Good luck, Hyper Harvest II
