We have a Peterson in a 9500, it works very well in sesame and klien grass seed.You close it almost shut to keep sticks out.Only trouble I have with it is that the adjusting linkage seems weak any small bit of stems or rocks have to be cleaned out to close down.Have a rigid in a 8820 but have no luck in these small seeds.It is alot lighter than the toothed chaffer and seems to save the shaker arms and bushings.Also it does a great job in wheat and milo leave set on full air.
