I am in the market for a used walk behind and have been offered a Snapper Pro Hydro Walk behind 36" 15 hp Kohler fixed deck. They say its been used at the dealers residence only. Looks like its about 2-3 years old and in decent shape. Started at 2500 but says I can probally get it around 2k with a 1 year warranty. I went to demo it but it hade been sitting for a few and needed some adjustments. I am positive that they would service it. Is it a deal or what?
