There were some fire-breathing beasts there that would scare the fenders off my new tractor. Look at this one:

35 Horsepower. Six-foot-wide cutting deck. Zero turn radius. Those were the official specs.
But unofficially, this thing could throw a squirrel 300 yards, easy. You can mulch, but if you use the bags you won't have to pick up the pedestrian body parts from all over the yard. Just imagine what this mower would do to your in-ground sprinkler system.
I have stood next to this thing. It's intimidating. Stay away, if you value your feet.
