Gravely ZT42 zero turn ride on mower with 42" cutting deck for sale. Only used for two seasons when Kohler 22HP engine seized after I had it serviced by some bonehead. Bought it new for $4000 (taxes in) 4 years ago. I see new ones are going for around $5 - 6000. Could be a project for someone to rebuild the engine or drop a new engine in and it's good as new to use or resell. Everything else works fine. Has been kept covered and out of the elements. At $600 it gives you lots of room to make a profit or you have a great mower that will last you several years without paying the big bucks for a new one.
