Does anybody out there use a Groundsmaster 120? If so, how do you like it? I might have an opportunity to pick up a used one of these. It has the same 44 deck that my walk-behind has, so it should cut good, because my wb does. I am wondering more about the stability and drivability of the machine. I do see a lot of guys using the bigger Groundsmasters at parks & municipal sites around here.
