Quikdraw, I do not want to start a brand war, as all units are probably good. I have been studying this adventure for 6 months. I feel from researching that the fecon is a very desirable head with great customer support. I visited a company a few months back that had been mulching for 6 years, started with bobcat machines, do not recall what cutter heads, they run 2 asv with fecon heads and just recently purchased a dedicated fecon machine. Recovery time, cutting efficiency, size of mulch may lean toward a particular brand, but I am after what I consider to be the best quality over all head and can sacrafice bigger mulch chips, 2 seconds slower recovery time, etc. If it is broke down and support is an issue, recovery time, chip size etc. not very important. I have ran bobcat, cat and asv machines. MY CHOICE is asv. I have not ran the bigger machines,(price of these machines-need big jobs) It would be wasting my time and the dealers time. Maybe down the road if things go well.
