As you can see I own 3 craftsman tractors. The old 42" cuts the best with all blades of grass cut and the lawn looking like a carpet. The newest 48" DGT6000 cuts the worst, leaving much uneven uncut grass. I'm on my 3rd set of blades and no change. I've tried high lift blades, Predator blades, and now Gator blades and its still the same. Is there a way to get my "new" tractor to cut nicer? How do the new 46" twin blade tractors cut?
