Losing what seems to me an excess amount of beans out of cylinder.
Not the shoe . I removed spreader to get a better idea as to where I was losing beans and it is definitely coming from the cylinder.
I tried 1 mph to 3 mph. No difference concave is set st 1/2" I tried opening concave more but then I was getting un shelled pods. Tried lo Range on cylinder.
Currently on hi at 460 .
First year with beans . Machine does fine in corn.
Thanks cory

Beans are 14%.
I did not try and close concave down less than 1/2" yet.

With the spreader removed, measure an 18 inch long (front to back) area where the straw has fallen and count the rotor loss. This is a two square feet area. Your owners manual has a chart saying how many BPA loss you'd have for a 15 ft head or 20 ft head. My memory fails me here and I don't have an owners manual. I do know for corn you have to have 2 kernels per square foot over the ENTIRE field to be 1 BPA. I believe soybeans is 4 kernels for EVERY square foot in the whole field to be 1 BPA loss. Corn loss would have to be 30 kernels in that 2 sq foot straw grid to be 1 BPA with a 6-30 head. Yes...30 kernels. So I think 60 kernels would be correct for soybeans at 1 BPA but check your book. Tighten your concave more or wait until they are fit. I used to get a lot more complaints in corn than soybeans for rotor loss, so I question what's going on here. Also not knowing how many changes have been made to the processor it's really hard to advise.

Are you cracking any? Thats a lot slower than i normally run. 600 is about as slow as ive had mine and haven't ever had loss. Shouldn't have to narrow concave up much if its threshing beans out of pod.

600 to 650 is where I usually run too, but too fast increases rotor losses and I have no idea what his processor is set up as.

Thanks guys. Iam not cracking any beans. I do have a manual.
Rotor is stock. Rasp bars and helicals are still good . Not new but good. Iam running cage sweep.

I'd also be SURE the processor area isn't plugged up with green tough straw !!!

If your moisture sensor/tester is reading 14%, then in theory the grain sample probably contains a few 15-17% grains? If that’s the case, then your rotor/concaves don’t have enough aggressiveness too thresh those few wetter grains? Or maybe think about it as though it’s taking too long to completely thresh soybeans from pods??
Try increasing rotor rpm to upwards of ~700rpm? Then G.O.A.L.(“get out and look”). If not threshing to your desire, then additionally decrease concave clearance by 1/8” increments until satisfied.

Thanks.
Will hopefully be back in field this weekend and will try to report back.

Increased cylinder speed to 730, pinched concave down a 1/8" less than 1/2". Seems to be better.
Thanks cory.
