  If your Toro Lawn Mower engine won't start, starts with difficulty, or consistently fails to run, there are several potential causes. First, make sure the fuel tank isn't empty by filling it with gasoline. If the tank has fuel, ensure the choke is on by moving the choke lever to the on position. A dirty air cleaner can also cause this issue, so clean or replace the air cleaner element. Check that the spark plug wire is securely connected to the spark plug. Inspect the spark plug itself; if it's damaged or improperly gapped, install a new, correctly gapped spark plug. Also, check for a dirty fuel filter and replace it if necessary. If you find dirt, water, or stale fuel in the fuel system, it is recommended to contact an Authorized Service Dealer.

Why is my Toro 30177 Lawn Mower engine losing power?

  Laura HillAug 8, 2025
  If your Toro Lawn Mower engine is losing power, consider these possible causes: The engine load may be excessive; try reducing your ground speed. A dirty air cleaner can also cause power loss, so clean the air cleaner element. Check the oil level in the crankcase and add oil if it's low. Make sure the cooling fins and air passages under the engine blower housing are free from obstructions. Inspect the spark plug; if it's pitted, fouled, or incorrectly gapped, replace it with a new one. Also, ensure the vent hole in the fuel cap isn't plugged by cleaning or replacing the fuel cap. A dirty fuel filter can restrict fuel flow, so replace it if needed. If you suspect dirt, water, or stale fuel in the fuel system, it is recommended to contact an Authorized Service Dealer.

  If your Toro Lawn Mower does not drive, there are a few possible reasons. Check that the shift lever is not in neutral; move it to a drive gear position. If that's not the issue, the traction belt may be worn, loose, or broken, or it may have come off the pulley. In either of these cases, you should change the belt.
