  Amber ClementsJul 29, 2025
  If your Husqvarna Lawn Mower won't start, several factors could be at play. It might be out of fuel, so start by filling the fuel tank. Ensure the engine is choked properly, referring to the “TO START ENGINE” section in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other potential issues include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), or water in the fuel (empty the fuel tank and carburetor, refill with fresh gasoline, and replace the fuel filter). Also, check for loose or damaged wiring. In some cases, the carburetor or engine valves may be out of adjustment, requiring professional attention.

  If the engine of your Husqvarna Lawn Mower will not turn over, make sure the clutch/brake pedal is depressed. Also, ensure the attachment clutch is disengaged. If these aren't the issue, check for a weak or dead battery (recharge or replace), a blown fuse (replace), or corroded battery terminals (clean). Inspect all wiring for looseness or damage. Finally, the ignition switch, solenoid, or starter might be faulty, requiring a check and replacement if needed.
