ROTATING BODY, MOWER, AND GRASS-MOWING METHOD

摘要

In order to obtain favorable cutting quality throughout a long-term, a rotating body has a brace that rotates integrally with a drive shaft of a mower, and a main body made of synthetic resin that is joined to the brace. The main body includes an upper body that is joined to the brace, a flange portion having a diameter larger than that of the upper body, a lower body having a diameter smaller than that of the flange portion, and an engaging structure with which the linear cutter is engaged. The upper body has, on the outer circumferential surface thereof, a plurality of outlets, from each of which one end of the linear cutter is pulled out. With the upper body integrally joined to the lower body with the flange portion therebetween, the linear cutter that is pulled out of each of the outlets is positioned above the flange portion.
