Well, it's new and Hustler's "entry level" Residential ZTR. It may be a cut above what you find in big box retailers for the money, but the sealed, non-servicable trannies(I assume HydroGear EZT's as I couldn't find any real specs on the Hustler website) and FR(Residential) series Kawasaki will probably mow 1 acre OK. I wouldn't expect commercial-grade endurance or cut quality, but again it would probably be better than what you find at Lowes or Home Depot. Even the Hustler Sport model is pretty well an entry level ZTR and you have to move up to the Fastrak or Fastrak Super Duty to get servicable trannies and more commercial-like characteristics. I would recommend you go to a Hustler dealer, look at all of the models, see if they'll let you demo them and then decide which fits your needs(and budget) best. Personally, I have a little over an acre and I made an offer on a 54" Hustler Fastrak Super Duty for the same I paid for my 52" Gravely Commercial. The dealer wouldn't budge and wanted $200-$300(plus tax) more for a "Residential" ZTR than I paid out-the-door for an entry level true Commercial unit in my Gravely. Hustler definitely makes a good product though, it's just a little early to tell on this new offering.
