I just found three super a's in a man's garage. They were used in his nursery business for years to cultivate, plant, etc. Two are in pieces, one is together with cultivators on it. He said the one that is together ran, but they haven't touched it for years. The two in parts are all complete(he says). He is not trying to sell these tractors, I happened across them when my friend decided to stop in one day that I was along. I want to make an offer on them, but am not sure what to offer. I don't want to take advantage of the man, but i don't want to get ripped off either. Any ideas?? Thanks, Matt
