An apparatus for aerating lawns or the like for forming a plurality of holes in a turf surface and the underlying ground having a wheeled frame supporting an electric motor that is coupled to a pair of perforation bits through a coupling drive which imparts rotational motion to each bit. The bits are held at a fixed vertical position relative to the frame and a pair of wheels are attached to the frame rearward of the bits, such that the frame is rotatable through an arcuate path about the center of rotation of the pair of wheels. An operator rotates the frame forward to insert the bits through the turf surface and underlying ground and rotates the frame rearward to remove the bits. The bits are designed to push the underlying ground in a direction downward and transversely to each bit as it is makes a hole to prevent the underlying ground from displacing in a direction upward and out of the hole.
