ABSTRACT:
An aerator for lawns and the like has spiders formed of four identically formed members. Each member has a tine on each end, so four members provide eight tines for the spider. The members are relatively narrow, and filler members at each side of the tine members provide stability to the spider. The spiders are carried by a frame, and the frame carries a weight-receiving tray for carrying weight to assure penetration of the tines. Springs carry the tray on the frame so the springs will absorb the energy if the tines engage an impenetrable object.
