TL;DR
A mulching mower blade is a cutting blade with extended, curved cutting edges that recirculate clippings inside the deck, chopping them fine so they fall into the turf as a nitrogen return instead of collecting in a bag. Used with weekly mowing at proper height, the clippings can supply a quarter of a lawn's fertilizer need without causing thatch.
What it means

Used with weekly mowing at proper height, the clippings can supply a quarter of a lawn's fertilizer need without causing thatch. It trades some bagging and discharge performance, struggling most in tall, wet grass.
