摘要：
Mower blade utilizes a blade portion formed on the blade main body and an air circulator portion formed on the blade main body and generating airflow via rotation centered around the vertically-oriented axis of the mower blade. The blade portion is arranged in a length-direction end portion of the blade main body and extends along a predetermined area in the length-direction. The air circulator portion is located opposite the blade portion in a width direction, has a rising upward portion, and extends along a predetermined area in the length-direction. A boundary portion is arranged between the blade main body and a rising upward portion of the air circulator portion has a portion inclined or angled with respect to the blade portion such that, beginning at the length-direction end portion, a distance between the boundary portion and the blade portion increases along the length-direction and moving toward the vertically-oriented axis. A height of an upper end portion of the air circulator portion measured from a surface of the blade main body is a substantially constant height.
