ABSTRACT:
A turf coring tool includes a tubular cut out wall section turf coring tine having an upper tubular end for receiving force contained within a socket and having this upper end of the coring tine walls severed with an axial slit from the cut out area, allowing the slit walls to become flexible counter to the axis of the tine. A tube having elastic qualities is placed in the slit section and compressed by a washered screw wrenched into the socket base to allow the distortion of the inserted elastic tube to distort the flexible slit tine walls against the inner walls of the socket. The resultant pressure against the distorted tine walls will allow them to become bound in the socket. Wrenching to relieve the elastic compression will cause the tine to be free and released from socket.
