2005 Scag Turf Tiger, 27hp, 61" deck

I have a Scag 2005 Turf Tiger, 27hp Kohler air cooled, 61" mower deck with 500 hrs on it. Excellent condition with more than regular maintenance. Solid front tires installed. What would you consider a fair price for it now. Sorry no pics. I'm in AZ and the mower is in VA. Thanks
