I watched RME’s video with a Louis the other day and I got a ton out of it. It’s lead me to put further effort into getting my 8120 to load the sieves more evenly. Overloading the right hand side is something that’s been a problem for sometime now and I think it’s exacerbated by my use of a stripper header, though the problem is just as bad in canola too. I’ve done just about everything I can with adjustments including moving my pinch point to the left, playing with concave clearance and rotor speedand using a sieve offset but the problem persists.

I’m wondering if there’s modifications I can make to help resolve this problem. I thought about putting a blank out plate on half of a module on the right side. Another idea would be putting angle iron pieces on the grain pan at an angle to help shift some material more to the middle. Has anyone tried anything like this or have any other ideas for me?

Up to 5 years ago I tried a couple things, I never tried your idea of fitting something to the pan because, from memory, I couldn’t think of a way to do it without making the modules a lot harder to change.....
On the round bar corn modules I welded some lourves (spelling!?) under neath to deflect the grain as it fell through the modules.
For summer harvest though I tended to run a range of modules so rather than that idea which was fixed, and wouldn’t have covered the range if conditions, I tried fitting some curved triangular deflectors under the modules.... from memory they bolted up near or at the point where the modules bolted in.
I think they helped a little however in the end running about 1.3 to 2 degrees offset on the sieves was a Mickey Mouse way around the issue..... it still takes a bit of pissing around to work out what number you need and may not stay consistent as the day and conditions change. I found as I tweaked the thresh from starting in morning thru the heat of the day then back to the end of the day the grain distribution changes. And not mention the side hill issue where obviously you’ll get less slope compensation on one side because the sieves are already tilted on the flat.

This will be my first harvest with my 7120. It will be a learning experience. Paying attention to detail hopefully I can get it to keep every expensive kernel in the tank. There are 3 cover plates per module with Wildfong concaves. That allows more customization for conditions than factory concaves.

New Holland TRs had adjustable louvers that hung down from the concaves. A rod stuck out the side of the machine so you could move them side to side. The side covers and the upper part of the concaves came out together. This picture isn't very good but it gives you an idea. The front one has the cover plates.

If you are returning any amount of grain it tends to fall through the concave on the right side. That was 1688. I guess new machines have rethreshers though. I ran a cover plate under the return auger discharge so the grain in the return would get swept across the concave and spread better before it dropped through and not overload the right side of the sieve
