  A Husqvarna Lawn Mower that's hard to start might have a dirty air filter (clean or replace it) or a bad spark plug (replace it). Other possible causes include a weak or dead battery (recharge or replace it), a dirty fuel filter (replace it), or stale or dirty fuel (empty and refill with fresh, clean gasoline).
