There could be a build-up of grass, leaves, or trash under the mower, so clean the underside of the mower housing. Other causes include a dirty air filter (clean or replace it), low or dirty oil (check and change the oil), a faulty spark plug (clean, regap, or replace it), or a dirty fuel filter (replace it). Stale or dirty fuel, or even water in the fuel, can also cause problems; in which case, empty the fuel tank and refill it with fresh, clean gas, replacing the fuel filter.

      If you're experiencing a loss of drive with your Husqvarna Lawn Mower, make sure the freewheel control is in the “engaged” position. For debris on the steering plate, see "CLEANING" in the maintenance section. Replace a worn, damaged, or broken motion drive belt. Purge the transmission if air is trapped inside. Install the axle key at the rear wheel if it's missing; see "TO REMOVE WHEEL" in the Service and Adjustments section.

    Why my Husqvarna GT48XLS Lawn Mower will not start?
    • A
      Antonio BerryAug 20, 2025
      If your Husqvarna Lawn Mower won't start, several factors could be the cause. It might be out of fuel, so start by filling the fuel tank. 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 tank and carburetor, refill with fresh gasoline, and replace the fuel filter). Also, check for loose or damaged wiring. If none of these steps work, the engine valves may be out of adjustment, requiring professional service.
