we are doing AlOT better feeding in our 5'tall green stem beans.sure dont think 1 thing only is the answer as you already no. reel placement is critical'even with orbit reel,coupled with your feed floor we have several smiling in ohio.1foot tall grass in drounded out areas with 1'tall beans are still a challenge with paddle tines from hart carter a big help. Dan your feed floor is the biggest help down the pike in a long time, increased capacity in corn as well.i have testimonials if you need them.they just cant figure out where all that stuff goes!!!
