Oatboy, At one time AGCO offered the front to rear cage sweep as a retrofit update. I installed five of these back in the late 80's early 90's. They do work well when you get into tough thresh conditions that send all the material through the cage. I have net seen one plug yet.The customers that have them are still running them. One from a P3 R60 should work even though it is a little different from the retrofit kit,but you may have to weld some of the pieces to your existing cage where the rollers ride and also at the top of where your access doors are you will have to weld in a couple of pieces. I still have a copy of the installation instructions for the AGCO retrofit kit.I could make you copies and mail them to let you see what is involved. Price from AGCO back when these cage sweeps where installed was around $1700.00. Hope this helps, Hyper Harvest II P.S. Have a Happy Thanksgiving!!!!!!!!!!!
