  Erica AndersonAug 29, 2025
  If your White Outdoor Lawn Mower is not mulching grass effectively, place the throttle control in the FAST position. Avoid mowing when the grass is wet; wait until it's drier. Mow once at a high cutting height, then mow again at your desired height, or make a narrower cutting swath. Also, sharpen or replace the blade.
