The present invention relates to a mower blade, and the present invention comprises: an assembly part formed at the center of the blade and comprising a connection hole so as to be connected to a drive shaft located inside a gear case of a mower; two side end parts protruding outwardly in the shape of an arc at both front end parts opposite to each other around the assembly part; a front part connecting the assembly part and the two side end parts in front in the propagation direction of the blade, and in which a first processing part is formed along the outer surface; a rear part for connecting the assembly part and the two side end parts at the rear in the propagation direction of the blade; and a first bending part formed by downwardly bending a part of the rear part on the basis of a first bending line connecting any one point of the outer surface of the two side end parts and any one point of the rear outer surface of the assembly part. Accordingly, the present invention can reduce the fatigue of a worker by reducing the weight of a mower through buoyancy according to the blade rotation, can improve workability, can effectively solve the problem of the breakage of blades caused by the easy bumping thereof against stone and the like on the ground or the injury of a worker caused by bounding stones and the like, and, by means of the wind that is downwardly discharged by the blade rotation, has effects of facilitating the cleaning of a cut object and enabling work to be more comfortably carried out by cooling the leg region of a worker. |
