I bought two Gravely's last night on ebay. I thought it was a good price. $500. Both run. He hasn't used the C 7.6 in 3 years but has been using the 566 up until recently. He listed the following attachements: One regular sulky, one steering sulkey, one commercial 40" mower, one rototiller and one pulley attachement. I sent him an email earlier asking about the pulley attachment but haven't got a response yet. Do any of you know what he might mean by a pulley attachment? I couldn't see anything in the pictures he posted on ebay either.
