The present invention is a self-propelled ground aerating system. The system comprises, in general, a wheeled platform that has disposed thereon a power pack, a steering mechanism, a hopper for distributing materials, and a spiked drum. The spikes disposed on the drum are selectively positioned to engage the ground at a selected angle. The depth of penetration of the spikes into the ground may also be selected. The power pack provides the required power to a drive mechanism which in turn provides power to rotate the spiked drum thus propelling the present invention.
