Husqvarna LC221FHE 21 in 163 cc 4-Stroke Walk-Behind Mower with Electric Start and Mulching Capability DECK CLOG Error Fix: Grass Clumping Under Deck

Grass clumps under the mower deck instead of being mulched or discharged — mowing wet grass is the primary cause; a dull blade tears grass into clumps rather than cutting cleanly; an accumulation of dried grass under the deck reduces airflow needed for proper discharge; scrape the underside of the deck clean before each season; sharpen or replace the blade; in side-discharge mode, a clogged discharge chute blocks clippings; in mulching mode, ensure the mulch plug is properly installed
