Abstract
A cutting blade for a rotary lawn mower to increase the mulching effectiveness of the mower comprises a generally rectangular blade having a central portion and radially outermost end portions. The blade is curved over its entire length to have a concavely curved upper surface across the width thereof from one end to the other. In addition, the radially outermost end portions of the blade are twisted reversely relative to one another to cause the leading edges thereof to slant downwardly as they extend from the central portion of the blade to the tip portions of the blade.
