Abstract
The present invention is a device that aerates lawn or soil using a unique triangular shaped tine or spike. The spikes are arranged on drums in a pattern. The drums can be filled with a fluid such as water or a granular material such as sand to adjust the depth to which the spikes penetrate. The drums may be angled with respect to the direction of travel to impart a transverse movement to the soil. The triangular shape of the spikes and the transverse movement greatly enhances the degree of aeration and results in significantly better aeration compared to using round spikes and coring devices. The surface is not cluttered with cored debris, so the present invention can be used on playing fields or lawns where post aeration appearance is important.
