Whats a good price for a 4 year old Scag 52 inch fixed deck hydro mower with a 17hsp kawi. Comes with new blades, belts, new tires, new grass catcher, was used supposedly by a landscaper for 800 hrs or so. He said hydros are good everything works fine. Whats a good price to pay? Looking for a quick response im going to check it in a little while.
