i have the first gen, which only cuts 3" max. i do allot of commercial and really needed a 4" height for proper cutting height to promote a healthy lawn. the floating deck is top notch, like a 36" commercial mower, slightly bigger front tires, the control handle bars are a much better design from the old gen, more user friendly and easier to control. i find myself enjoying using it now, my old one is still kicking strong after 5 years of commercial use. thats why i bought another one, the 28 fits just about anywhere and feels like one of the big boys. i recommend!
