I was getting ready to buy a JD 757 z-trak. I wanted a Hustler Super Z, with the top speed (15mph), but I was concerned about quality of cut. Dealer in area (which sells both Hustler and Exmark), told me Exmark was the better ztr, better cut, but this particular model (don't remember exactly: Lazer-Z w/60" deck for about $8400). I have a JD lawn tractor, 4 yrs. old, and then looked at JD ZTRs, since perhaps JD dealer could take my old one off my hands. I was surprised at the price (for JD) for 757: $7299 w/60" deck, cheaper than Exmark, and $200 cheaper than the Hustler. Now I'm reading that the JD doesn't cut as well as the Exmark. Quality of cut is important if you're cutting professionally. Just how much worse (if at all) is the JD than an Exmark? Does anyone have experience seeing both in comparison?
