I have one on the front of my Deere 333e. I love it, it is very fast compared to the drum type mulcher I have used in the past. There is a good 30 hour learning curve for a new user. There is a little more chance for throwing debris but at least you can tell that you did it and where it went. The front of my machine stays so much cleaner than when I ran a drum and was covered by slippery vegetation. A down side is that it sticks out there a little further and it weighs quite a bit.
