摘要: An exemplary embodiment providing one or more improvements includes a frame which is attached to the front or rear of a lawn mower, and a spike assembly attached to the frame which provides spikes on rotating collars. The spikes penetrate and are withdrawn from the soil when the mower is moved, thereby aerating the soil. Embodiments can be attached to a vertical or horizontal surface on a mower. Guards optionally may protect the user from any injury.
