Thanks for the reply. I'm sure that I'm buying an sts (not that I think they are superior, just that if JD has phased out the walker machine I don't want to buy something that is already obsolete). A rotor will be something very new to me but I guess I'll learn. Seems that there is a ton I can learn just by reading these forums. I just wanted to be sure that I can do at least as much as my old massey 860 can do. Also, the 9560 is the only thing I can afford for the size farm ours is (not that $160,000 is exactly cheap).
