  Cynthia GarciaSep 5, 2025
  If your Husqvarna Lawn Mower isn't mulching grass effectively: * The engine speed may be too low. Set the throttle between 3/4 and full throttle. * The grass might be wet. Avoid mowing when the grass is wet; wait until it's dry. * The grass may be excessively high. Mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting strip (e.g., 1/2 width). * The blade may be dull. Sharpen or replace the blade.
