Hey Retro, you still selling Badboy? I believe you on the blade tip speed. I ran a Hustler with a rear discharge about 3 yrs ago and noticed that it seemed to be running slower but I didn't really put much thought into it. It makes sense because the clippings don't have as far to travel, just like I mentioned before. I had to keep looking back to see if the mower was actually cutting the turf-I was used to seeing and feeling clippings come out the side. How does the cut on the rear grasshopper compare to the Hustler? Does the Hustler have that fourth blade also?
