Went grinding today with the new Carlton. It worked really good! I did a bunch of pine stumps and with the sandvic wheel it seemed like he mulch piles were much more manageable and did not throw chips all over the place. As far as having 1-machine this is as close as your going to get. However it's hard to beat the big power and chip containment of a pull behind. For the money I would say this is the best machine out there. If you buy a 4012 make sure to get the kubota, 4x4 and sandvik wheel. I did get the blade and it works great too. I demo a Bandit 3800 (2005 model) and it worked ok the wireless work great. The swing speed was slow. I believe the 4012 would beat the 3800.
