  If the engine of your Husqvarna Lawn Mower will not turn over, make sure that the clutch/brake pedal is depressed and the attachment clutch is disengaged. Check the battery and recharge or replace it if it is weak or dead. Replace the fuse if it is blown. Clean the battery terminals if corroded and check all wiring for any looseness or damage. Check or replace the ignition switch if faulty, and also check or replace the solenoid or starter if faulty. For a faulty operator presence switch, contact an authorized service center/department.

  If your Husqvarna Lawn Mower's engine clicks but doesn't start, begin by checking the battery. It might be weak or dead, requiring a recharge or replacement. Also, inspect the battery terminals for corrosion and clean them thoroughly. Ensure all wiring is securely connected and free from damage. If these steps don't resolve the issue, the solenoid or starter might be faulty, necessitating a check or replacement.

  Jillian LozanoAug 18, 2025
  If your Husqvarna Lawn Mower is hard to start, begin by checking the air filter and replace or clean it if it's dirty. Replace the spark plug if it is bad. If your lawn mower has a battery, recharge or replace it if it's weak or dead. Replace the fuel filter if it's dirty. If the fuel is stale or dirty, empty the fuel tank and refill it with fresh, clean gasoline. Check all wiring for any looseness or damage. In case of a carburetor or engine valves maladjustment, refer to the 'To Adjust Carburetor' section in the Service Adjustments manual or contact an authorized service center/department.
