I've narrowed my search to a John Deere Z930M with either a 60" deck, a 60" MOD deck, or a 72" deck. What would you folks suggest as far as quality of cut, striping, quality of mulch, maintenance, etc? I've read that the MOD decks don't cut as well as standard decks and that they don't mulch as well as standard decks with mulch kit. Agree? If std 60" vs std 72", I've read that a 60" gives an overall better cut than a 72". Most of what I mow is fescue ... and of course clover lol.
