For whatever its worth ,a small rod at a steeper angle than the divider mounted on divider may help, the lenght of rod will depend on lenght of stems. Also try running reel faster than normal and as far forward as proper feeding will allow. But the long diivders will help the most and can be adjusted to divide crops in diff. conditions. I think I have same dividers as you without that problem ,but have rowed beans and very little lodging, also have crary air reel which may have slightly diff reel.
Also thanks for the info on my problem "pushing dirt". I have tried many diff. table heights without much difference. I am done with the short beans and am in tall beans w/rocks and the feeder tilt setting is ideal for these conditions. Thanks again.
