A mower blade with a trailing sweeping edge that projects below the cutti ng edge serves to brush cut particles deposited on the grass surface down betwe en the grass blades and up into the air stream within the mower deck. As the cut particles are recirculated in the air stream, they are recut in a mulching action. The particles forced down between the grass blades reduce the amount of cut grass that has to be discharged. As a result, the amount of cut grass particles left on the lawn is reduced, thereby providing an improved appearance.
