I am thinking of buying a 2 year old 61 inch Great Dane ZTR. It has 270 hours on it and has been well maintained. I know this cause I have used it for about a year. It is owned by a friend of mine. He keeps on lending it to me to try and sell it to me. I like the machine and am thinking about buying it from him. It has a 26 Hp Kaw on it. Is there a web site out there that shows how much used equipment is worth? Or can you guys tell me what you think it would be worth. Thanks.
