Title: Turf aerating device

Abstract: Disclosed herein is a turf aerating device including a cylindrical drum rotatably supported from a frame for rolling travel over the surface of the turf to be aerated, a plurality of circumferentially-spaced, core-forming elements or tines mounted on the outer periphery of the drum in laterally-spaced, generally parallel rows, and a plurality of guard members mounted on the frame rearwardly of the drum axis. Each of the guard members extends toward the outer periphery of the drum to a location adjacent one of the rows of tines and has a surface located to travel closely adjacent the turf surface and thereby positively restrain the turf from being pulled upwardly by the tines as they are withdrawn from the turf after penetration. The guard members terminate in a generally straight edge closely spaced from the outer periphery of the drum so as to serve as a scraper from removing debris collecting on the drum.
