I had the same thought about the rotor, it is as slow as it can possibly go right now. I have the fan up as far as it can go without throwing too much over. It may have been worse before I got the fan speed all the way up or it could just be wishful thinking on my part.
I will remember the part about the auger, thanks.
I can remember when doing sunnies a while back , I had dropped the stone trap for the night and then went thrashing the next day and couldn't figure why there wasn't anything going into the hopper -- be damned if I forgot the door . It is amazing how much gets thrashed out by the feeder chain as there wasn't too much in the head parts on the ground but LOTS of seeds .
