We have two heads and one of them has the raised feather sheets and the other one has the Johnson bar. The raised feather sheets do help the feeding a lot and does a good job keeping the rocks out. The downside is trying to get the beans that shell out up the incline and into the auger. We are going to try installing a 1" tube at the sickle and run some air through it to try and get those shelled beans blown into the auger, I think if we did this the raised feather sheets will be perfect then. As far as the Johnson bar if the beans get to short it dams them up and then the reel has them pretty well shelled out before they get flipped into the header, but this only happens in real short beans. As far as the hose you can expect the same performance as the Johnson bar, but you won't have as good a seal at the sickle and we found that the occasional weed would get caught under it. If I can find the time I would like to make something similar to the Johnson bar but have the bar angled at 45 degrees and put an air hose behind it to push the shattered beans up the incline and into the auger. This should keep the head clean and keep the dirt and fines from sifting through the feather sheets and onto the skid plates. I think we all know the problems that causes when the skid plates are full of dirt.
