If I remember right I was in the 350-4 ballpark when I bought mine a few years ago. It does alright in normal conditions and mulches pretty good if its dry. I just had to complain a little. I see Hustler made a 21 for a little while. Id like to find a cheap one of those , then I would match ..lol Got a 35 yd mulch job yesterday Well see what today brings. Cold and rainy so far.
