My friend has a Toro Prolline 36" thats about 3 years old. He hardly ever uses it and it just sits at his property. I was thinking about seeing if he wants to sell it but I don't know how much these are worth. Can anyone tell me if this is a good mower and about how much you think its worth. Or what you would pay for it. Same thing I guess. It has a 13 hp Kawasaki and the T-bar controls. Is there some kind of blue book for lawn equipment? Thanks for your help.
