ok Dan I thought you had posted some pics.of your sweeps but I can't find them, just what are they how are they installed and how and what do they actually do? I have a R-52 '98 model, I have redone the rotor high low bars,( set up like shown on the hyper mod post. extended ends,new feeder floor,(hump out) what improvement will the hump kit on the rock door do? what am I missing, would like to use a enclosed rotor but still haven't read about one that would work in all of my crops, (corn soybeans milo and wheat. Tks. for all your help in the past to me and other's on here.. Tks. Bob
