There are four divisions of Hustler Commercial mowing machine: Hustler Z Hustler Super Z, Hustler Mini Z, and Hustler Super Mini Z. Do they all cut the same and have the same decks? If a 52" Hustler Z had a 27HP engine and a 52" Hustler Super Z had the identical 27HP engine, would both mowers cut the same? Is the only difference comfort features? Also, what make a Hustler ZTR better than a Toro ZTR assuming both parties providing the same great service? Thanks in advance.
