Does anyone run round bar concaves in wheat on their STS machine? We have a corn combine and aren't satisfied with our results in wheat with those concaves. We might get small wire concaves to switch out to in wheat and milo. In the meantime, I was just wondering if there is any tricks to getting round bar to work in small grains with any attachments. We currently run two concave inserts on the first two rows and the next three we have closure strips. No matter what settings on the combine (cylinder,concave gap, sieve, fan, etc.) we cannot get the white caps out of the sample. Anyone with any suggestions?
