Abstract
Official abstract text for this publication.
A cutter blade for a mower is driven to rotate about a vertical axis inside a housing. The cutter blade includes a blade body, a blade portion formed in the blade body and a wind generating portion formed in the blade body on its side opposite in a width direction thereof to the side where the blade portion is formed, the wind generating portion being formed by being raised and bent from the blade body over a predetermined area from an end in a longitudinal direction thereof. At an outer end portion of the wind generating portion in the longitudinal direction of the blade body, there is formed at least one recessed portion recessed more inwards than the remaining portion of the outer end portion.
