i have run the 60 and 90 for a while broke the 60s suspension the 90s a monster though one thing that scares me is that theres not much protection for the hyd drive lines not that ive broken one but there always seems to be a piece of random crap near themI have seen alot of ASV RC 100s with the forestry package running mulchers. They flow 38 gallons a minute I think and have about 100 horsepower. Here are some used with mulchers included.http://www.machinerytrader.com/listings/list.aspx?ETID=1&Manu=ASV&Mdltxt=RC100&mdlx=exact&GUID=7DA199B220AD42BD9B8B96A19D4AF3FB
