I'm ready to pull the trigger on a BX260. Went to 2 Kubota dealers in NH. When I mentioned the fine cut deck both said they don't recommend them. Asked why, the reply was "the terrain in New England is too rocky for that type of deck". I mulch cut and it seems that the fine cut deck is better suited for that. I realize that you can add the mulch kit to the standard deck as well. Can anyone fill me in on why the two decks are different?
