I have new to me 9660 walker an can't seem to get clean sample in dry(12) barley. Lots of 4in long straw in hopper. Enough to bale
Concave gap 5 an. 850. Fan 1200. Bottom sieve 5 top 18 an chafer 18. Help would be very nice thanks

Try opening up your concave a touch and opening the bottom sieve. Dry barley should take almost nothing to thresh, 850rpm almost seems a little quick for cylinder speed too.

Ok thanks. Any other suggestion would be nice

might be a little late but is probably coming from your precleaner as anything that drops through goes directly to the grain tank. Yours may have sprung open a bit and straw is spearing through from the grain pan below the walkers. Seems no matter what you do, you cannot get those fins completely closed as there are always a few that are sprung a bit. Precleaner of no use to grain farmers, I wish JD would offer a grain pan option to replace the pre cleaner sieves to small grain farmers.
