trouble with a M2 in beans

Alright I’m asking this for a guy at work, they (his family) have a M2 combine that they have a hard time cutting beans with. The beans are very dry 9 to 10% but the stalks still have a little green left in them, and the stalks are plugging up on the threshing beater.  Right now they set the feeder beater slip clutch so light it plugs up there instead of inside the combine. He said that they’ve tried everything that they have heard of except a spiked beater and he don’t want have to change it for corn and that they are hard on the corn. I hope that my explanation is accurate.

#1. lower the cylinder lower than you have it now, to chew up the green straw so it can't wrap....usually less than 1/2" and probably around 3/8". #2. Have the correct pulley/belt combination on the cylinder, so the speed can be as high as 800 rpm's !!! ...operate the cylinder speed high enough that you damage some beans and then just slow it down enough to eliminate/reduce splits...speed is your friend here. #3. Install a 25 tooth drive sprocket on the left side of the cylinder to speed-up the thresher beater (std is 18 tooth). #4. Remove the lower/front raddle guard if it has one...this usually aggrivates wrapping of the thresher beater. #5. Over the top of the main seperator raddle there is a steel curtain....remove it and throw it away for corn and soybeans. #6. Worn out cylinder bars really add to the misery of green stemmed soybeans. #7. wait for a killing frost and repeat #1. thru #6.

I have a question about our L3 (sorry for the hijack)  Is the cylinder closer to the back of the concave than the front?  Or Is the clearance closer in the back than in the front?  It sure appears this way!

When we bought our Gleaner back in 1987 the dealer told us if we were having a problem with wrapping we were on the wrong side of the shed door. 8-9% beans dont mean a thing, a heavy dew, light rain a day of fog there back at 16. Personally I would rather harvest dead ripe beans at 15% and take the deduction than to fight 8-9% green stems and take the huge beating on weight when you sell them. Another funny, but unexplainable thing about waiting is they seem to yield better, not sure if its from the cracking, or shatter or where the extra weight is coming from, but what I do know is I get paid by weight. If the neighbors are all grinding the beans off that is not an idication that they are ready, and there is no prize for being the first one started and the first one finished.

i have an almost new set of factory stylr bars in KY- i would sell them cheap but the shipping to mo would be a killer
