It's not so much the hours as it is the maintainence performed during those hours. Oil changes, grease, schedule maint.. Keep it all up and hours really don't matter.
My buddy Armondo(tree farmer) has a Badger with 3,000 hours on it going for 6K. It's in really good shape(Grinding up fruit tree branches once a year) but needs paint as it was stored like any other farm equipment. I could PM ya his # if ya want, and don't mind the drive.
