I don't think floating decks wipe out scalping completely, but they do help. It depends on what you have the scalp wheels set and what height you are cutting on. Don't get me wrong, there is a big difference between floating and fixed decks!! I wouldn't drive through a yard thinking that its not going to scalp anyhting, because it does, it just depends on the terrain and how you handle it. Takes practice and knowing what your machine can and can not do, that is the best way to avoid scalping. Overall, the floating decks are a lot better than the fixed decks!!
