I know this subject has been visited before. I was talking to my dealer about this and he couldn't recommend it and had never heard about it. I'm running a Scag SSZ 52" and a Great Dane Super Surfer. I'm all for better dispersion of clippings. I understand that longer bolts may be required. Where does one find these? Also, when putting the blades on, would I just put them at 90 degrees and the bolt holds them in place. None of the guys up in this area have heard of using double blades. What works best, the gator blades, high lift or just a standard blade?I may start a trend.
