I'm mowing with a Walker MB 56" ZTR.
http://www.walkermowers.com/MODELBspecs.htmlIt was the only zero turn I could find that could handle a 3:1 slope fairly safely, unless the grass is wet. The deck sticks out a fair distance from the drive wheels so I can just run around the pond NASCAR style blowing the algae producing grass clear of the pond. It stripes nice too and is low enough to the ground that I drive under low hanging trees. My only complaint is that you sit right on top of some pretty small tires making for a rough ride at times.
