Im in the spot where its looking like im going to need to add a 72" machine to our mowing line-up. I have a 48" hustler WB that we have been VERY happy with. In terms of dealer support my dealer sells both DC and Hustler so thats not a issue. I need a machine that can handel alot of grass. And mowing conditions that are not ideal at times (wet ect.) I know that the Hustler is faster but how fast can it mow? Does the new XR-7 deck increse cutting speed? And whats Hustlers stance on double blades? I would really like to have my mowing crews with all Hustlers what do you guys think >?
