I finally decided to try out a Hustler Super Z and see what all the fuss is about. The one I demoed had 200+ hours on it and it had a 66" deck with a 30 Kohler. My Scag has a 61" velocity deck with the 29 DFI Kawi and has 200+ hours on it. I'm going to give my opinion but they are nothing more than my opinion and not someone leaning toward a certain brand. First impression:The Hustler is blistering fast just like everybody said it was and will run circles around the Scag as far as cutting. Like Tacoma pointed out, the Scag is severely dampened and takes some getting used to. The Hustler has the typical sensitive levers like the Exmark's I had and this is what I prefer. You really have to push the TT down to get it rolling. Cut quality: I had heard a lot of negative comments about the poor cut on the Hustler but I didn't notice. Both machines had brand new blades. I'd consider the Hustler to have an average cut. I mowed my rough cut at 2.75" and my fescue at 3.75" and it did fine. However, the velocity is second to none. It just seems to have better lift and continues to cut good even when the blades are dull. The 61" deck has a lot of rollers on it also and it automatically leaves a nice stripe that my Exmark's never did. Also, the Scag has a spring assisted lift that makes floating the deck a breeze and I use it constantly. I was killing myself trying to do this with the Hustler. On tedious turf, this is very important. Ride: The Hustler didn't have the flex forks but had a standard suspension seat and it rode ok. It's funny but the two mowers had the exact same seat but they are night and day as far as ride. The Scag is like sitting in a lazy boy and rides really good while suspending you up and down with the terrain. It also has a lower COG and you feel like you are sitting in the machine and feel secure. I felt like I was sitting on top of the Hustler out in the open. Hillside stability: NO CONTEST!!!!!!!!!The Scag walks the dog in this category. It has a lower COG and sticks to hills like glue-literally. I ride some pretty nasty ditches and hills and the Scag rarely slips a tire. The Hustler is actually wider but I wouldn't trust it as far as I could throw it. I was spinning tires each time I'd turn it and it wasn't from speed. If you pointed it down on the slightest incline, it started sliding and felt like it had no weight on the rear. However, when you'd take off, it wanted to wheelie. The balance of the machine was very strange. Even the Exmarks' I had held hills much better than the Hustler. I was very surprised with this fact. Quality: NO CONTEST!!! I've had two Hustlers in the past and am used to a very quality machine but didn't see it with the Super Z. This really disappointed me. The front casters had one bolt holding them on and when I'd get up speed on the asphalt, the wheels wobbled so bad, it was dangerous. When I returned it, I found one bolt really loose and I've never run into this before on other machines. The sight lens on one of the fuel tanks was already buckled in and with only 200 hours. The veneer around the gauges was already peeling up. My Scag looks like new. One of the rollers on the deck was falling off and bent. The metal it was attached to was only one sided and the Scag is two sided-a lot more metal.The front wheels are air filled on the Hustler and the Scag has no flat fronts as standard. The Scag is doubled framed in a lot of places and just plain has more metal and is much better built-you're getting more machine and something that should last longer in my opinion.Everything on the Scag just feels beefier and the Scag feels like a cadillac compared to the Hustler. Engine: I didn't give this much thought because I wanted to compare mowers. However, I think the Kohler had better power over the Kawi, even though I'm not a Kohler fan. The choking and lack of LC does seem old school to me at this point, I admit. Conclusion: The Super Z is a fast machine and I would still buy one despite it's shortcomings. It cuts a lot of grass in a hurry and that's what I do-it would be an asset to me in that regard. It seems to be a better fit for rough cut though-schools, churches, etc. That's Hustler's first intentions-rough cut-industrial mowing but I don't think that's where they had intended to be in 2009. They still have some refining to do but they are a great company and I have confidence in them-they are very pro active compared to other companies. If I was wanting to cut a lot of grass fast, I'd get the Hustler off the trailer. However, if I was wanting a better quality cut and had some tedious mowing to do, I'd get the Scag off the trailer. If I wanted to mow embankments, I'd get the Scag off-no questions asked. There it is in a nutshell, I hope this helps someone.
