Use the Peterson in a 9500 does a good job in klien grass and sesame.The adjusting leakage seems weak but once shut down it keeps the sticks out.Play with the fan to fine tune.Our 8820 has a rigid but willnot work in these crops.It does a perfect job in oats,wheat and milo.Its also lighter than the toothed chaffer so it saves the shaker arms and bushings.
