    Why won't my Toro Riding mower start?

      Gregory TorresAug 20, 2025
      Your Toro Riding mower might not start due to several reasons: the fuel tank could be empty, so fill it with fuel; the air cleaner might be dirty, so clean or replace the air cleaner element; or there might be dirt in the fuel filter, so replace it. For issues related to dirt, water, or stale fuel in the fuel system, it is recommended to contact an Authorized Service Dealer.

      Shawn MedinaAug 22, 2025
      If your Toro Lawn Mower's engine won't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank is filled with gasoline and the fuel valve is open. Next, make sure the choke is on. Check if the air cleaner is dirty and clean or replace it if necessary. Also, verify that the spark plug wires are securely connected to the spark plugs and that the spark plugs are new and correctly gapped. Finally, inspect the fuel filter for dirt and replace if needed. If the issue persists, it could be due to dirt, water, or stale fuel in the fuel system, in which case you should contact an Authorized Service Dealer.

    • K
      Kristina SmithAug 27, 2025
      Uneven cutting height on your Toro Riding mower could be due to several reasons. The blades may not be sharp, so sharpen them. Bent cutting blades should be replaced with new ones. Ensure the mower is level from side-to-side and front-to-rear. Clean the underside of the mower if it's dirty, and adjust the tire pressure if it's incorrect. For a bent blade spindle, contact an Authorized Service Dealer.
