I have a decision to make in less then 48hrs. Here's the scoop: I added a new com'l account and they have a huge steep hill which occupies about 75%of the lawn. I cut some scary steep hills now with a Z but this one is walk-behind ONLY. It's tiered mid way and the slope is held up by a 8' high retaining wall that runs a span of about 200'. From the top of the wall to the top of the hill is about 80'. This is the only account I'll ever need to use a walk-behind on, so here's what I'm stuck between on. I can buy a over stock New 2010 48" Metro for $2989 OTD full factory warranty, or an '06 TT w/jungle wheels used by a LCO as a back up (he says) for $2200. Any thoughts?????
