Abstract
A turf or soil aerating apparatus includes in one embodiment a carrier drum having a plurality of turf aerating tines pivotally supported thereon such that movement of the drum along a turf surface establishes a pattern of aerification holes in the turf. In one embodiment, a tubular coring tine is provided having a generally cylindrical elongated shank portion, a sharpened penetrating end and a bulb portion proximate the penetrating end, the bulb portion having an outer diameter greater than the diameter of the shank portion so as to substantially eliminate friction drag on the shank portion during turf penetration. The inner surface of the shank is sized to facilitate easy passage of turf plugs through the tine. In an alternative tine embodiment, a solid shatter core aerification tine is provided which includes a solid body having an elongated cylindrical shank portion terminating in a generally spherical shaped bulb portion defining a penetrating end of larger diameter than the shank portion so as to substantially eliminate friction drag on the shank portion during penetration into the turf or soil. The tubular coring tines and shatter core aerification tines may also be carried by turf aerating apparatus operative to effect substantially vertical reciprocating movement of the tines during aerification.
