We used a non adjustable Petersen in our 93 R62 in grass. It did OK, but nothing great. It did help keep some straw and leaves out of the bin.

Since the sieve was in the combine anyway we went right into wheat with it. We couldn't save grain and it cost us at least a mile / hr. Don't know why it behaved that way. In defense of the sieve we didn't give it much of a try. Once we saw it wasn't working out it came

The dealer I purchased it from (used) said the round hole sieves are a hit and a miss in Gleaners. Some guys like it and some don't.
