I picked up a tiller today. It's a Ariens 7HP Rear Tine Tiller. It was a customer's of mine that I do regular maintenance for. He had two tree stumps that he had ground and he said if I would fix the two areas and sow new grass, that I could have the tiller in trade. It needs a little work, but nothing too terrible. What do you think? Did I get a good deal or the short end of the stick?
