If you don't have many trees around the yard and your fall blanket is minimal, a lawn mower could work as a leaf shredder in a pinch—simply mow over the leaves and collect them in the mower's bag attachment. However, with several price-friendly options on the market, it's better to take the easier route and buy a leaf mulcher. A specialized leaf vacuum and mulcher does a more thorough job picking up the leaves and shreds smaller than a mower can.
