I recently purchased a Bluebird aerator, also known as a plugged or corer. Is was an ex hire company machine but in recent years was owned by a landscaper who specialized in lawns. I am trying to work out how old it is and the model number. There are no numbers on the machine. The weights are inserted in the front and fit between the tynes, whereas the newer models have the weights on the side. Any help appreciated. I paid $1250 for it , the tynes appear worn, so I will probably replace them in the near future.
