I had a chance to get onto a Super Z and figured I would post what I found. I would of been more interested in the Super Z at the time I purchased my JD, but dealer support was key. The Hustler was a 60" XR7 with a 31 Kawasaki. The John Deere is a 60" 7 Iron and a 27 Kawasaki. For the Hustler's highs,the hydro's are super responsive, good stance, smooth ride and seemed to stripe well. Other nice features are flex forks, hydro oil cooler, and Michigan type suspension seat. The downs of the Super Z are with the flex forks, scalped more than I would expect, no real fuel gauge, and the after cut left stragglers at medium speed. For the John Deere, the mower is stable, steering is very precise and smooth. It also requires less stick movement to turn than the Hustler. The ergonomics of the JD is far more superior than the Hustler. The placement of the controls and deck height adjustment system is much better on the JD. The lows for the Deere are it is much slower in a drag race, and it sits much higher than the Hustler. I feel completely stable on the Deere on hills, so that is not such a big deal, but for others, you will notice it. The Deere cuts better, but the Hustler stripes better. Both units had suspension seats and no stripe kits. The Hustler has its place, but for my accounts and comfort, I would have to choose the Deere if I had to choose one. I will post pictures of the two side by side here soon.
