Had to take my Walker to the dealer the other day. While they were trying to figure out the problem, I was looking at all the toys. Man I love looking at all that new shiney paint. Anyway I happen to look at a model MB and noticed something looked different about the deck ,so I asked and they told me it was the new mulching deck. Upon further investigatoin this dude is completly different than my deck [mine is only 5 months old] it is on a bigger frame, seemed to be deeper and had different blades. They said it was for high capacity mulching. Has anyone tried one of these decks?
