There is disclosed a ground aeration device which forces aeration spikes into the soil without requiring ballast weight. The aeration device is comprised of a cylindrical roller having a plurality of spikes projecting therefrom, the spikes being aligned in a helical row which extends once around the circumference of the roller; support arms having the roller rotatably secured to one end; and mounting brackets which are adapted to mount the opposed ends of the support arms to the front of a lawn mower, the support arms being oriented toward the ground at an angle of between 30 and 60 degrees in relation to the horizon such that the spikes of the roller penetrate the underlying groundsurface.

A ground aeration device, comprising: a. a cylindrical roller having a plurality of spikes projecting therefrom, said spikes being aligned in a helical row which extends substantially once around the circumference of said roller; b. support arms having said roller rotatably secured to one end; c. mounting brackets which are adapted to pivotally mounted the opposed ends of said support arms to the front of a wheeled trolley such that the forward motion of the trolley forces said spikes of said roller to penetrate the underlying ground surface, said support arms being oriented toward the ground at an angle of between 30 and 60 degrees in relation to the horizon, (such that said spikes of said roller penetrate the underlying ground surface).
