I would like to get another aerator. Has anyone here heard of a Ryan model "Reno Thin" or something like that? I have an opportunity to get this aerator with a 4 hp Honda for $500.00 Cdn. New Bluebird is another $2700.00 This is what I know about the aerator; It has two chain drive, sold axle, four wheel independent steering, throttle is like a motorcycle hand grip type, four tines, and the 4 Hp Honda. Any suggestions on what year or model this is and any comments about the machine itself? To buy or not to buy??
