We traded off grandpa's B, it's been at the farm for 50 or so years, its been on mowing duty for the last 20 years or so.  It worked fine just slow, to many obstacles and too much turning.  It's being replaced by a Woods zero turn we've used in our yard for the last 15 years.  The new Grasshopper will be staying in our yard.  I'm sure at some time they will both get used in the same yard just to see how fast we can get done.  This is the only "new paint" around here this year.
