ABSTRACT:
An embodiment of an overall approximately rectangular rotary mower blade, affixed to a powered support shaft, where the support shaft rotates the blade tines on a rotational plane parallel to the vegetation to be cut, where the blade employs aerodynamic tines preceding the main cutting edge. Features of the aerodynamic tines improve cutting, mulching, and safety of mower operation.
