lA, If you want the chaff spread you will have to get a chaff spreader. I have been using a Vittetoe single spreader on my TR's. It is easy to install and I have been moving it as I trade combines. It runs off the reel hyd. It would not have any trouble spreading 20'. I take it you now own a TR86 with a 20' headIJ I can't help you with the YM as I would like to have one also someday. later, IlNH
