I am going to be buying a new Hustler Super Z in the next couple of weeks (Merry Christmas to me) I will also be getting a bagging system for it...I know why bag? It because the people I work for demand it in the contract...anyways to my question. What type of bagging system is best the bac-vac or the three bag system. has anyone used both? How good does the Hustler bag? I hope to mulch most of the time, but I have to bag also. While im asking any suggestions on engines would be helpful...Im leaning toward the 28 hp kohler.
