Abstract
A cutting blade for a rotary mower has a generally horizontally disposed, elongated blade body adapted for rotational movement about the vertical axis thereof when operatively connected to a rotary mower, and a plurality of fins attached to the blade body, each fin extending generally vertically from the blade body and away from the vertical axis thereof and disposed at an angle to the longitudinal axis of the blade body such that the outwardly facing surface of each fin is presented to the air upon rotation of the blade. In operation, the fins force air and grass clippings upwardly and radially outwardly from the rotating cutting blade.
