Running Oats Through a Rotary Gleaner Question

I would like some advice as to how I can clean up my sample when running oats through my R50. Here's the situation:



It's a 88' R50 with the standard chaffer and sieve. It does not have the option of return to cylinder on the returns, only back to the accelerator rolls.



Last year was the first year for the R50 in oats. I ran with the book settings and I left the filler bars (3) in the concave as I had previously done wheat. I "tweeked" the settings a little as I went along to minimize rotor and shoe loss.



I think I'm getting too many little pieces of straw in the grain tank. I'm afraid to turn the wind up too high for fear of blowing oats over the shoe. Would it help any if I took out the filler bars? Would a perforated finishing sieve clean up my sample?



Any insight anyone who runs oats through their rotary Gleaner would be appreciated.



Thanks, Tom K.
