摘要： A conventional tine used for management of a broad expanse of grass is manufactured by cutting a long hole-shaped opening in the middle portion of a pipe. As a result, the width of the opening is narrower than the diameter of the pipe, a plug resulting when a tip of the tine bores a hole in the grass does not easily drop out from the opening, and the tine is easily clogged. A tine according to the present invention includes a hollow cylindrical tip insertion (11) that is tapered and becomes thinner as it approaches the tip, a base grip (12) apart from the tip insertion (11), and a connection (13) for connecting between the tip insertion (11) and the base grip (12), wherein the connection (13) includes an aperture (15), and the aperture (15) has a circumferential angle of 180 degrees or greater centered around the central axis a of a virtual hollow cylinder (17), which is formed by extending the maximum diameter portion of the tip insertion (11) toward the base grip (12).
