  If your Toro Lawn Mower engine won't start, starts with difficulty, or stops running, several factors could be the cause. First, ensure the fuel tank isn't empty by filling it. Check that the fuel valve is open. If the engine still doesn't start, make sure the choke is on. A dirty air cleaner can also prevent the engine from starting, so clean or replace it. Inspect the spark plug wire(s) and ensure they are correctly connected. Finally, a faulty spark plug can cause starting issues, so replace it with a new, correctly gapped spark plug.

  Mr. Ricardo Ingram DVMAug 8, 2025
  If your Toro Lawn Mower engine is losing power, there are several potential causes. First, check if the engine load is excessive and reduce your ground speed. A dirty air cleaner can also cause power loss, so clean it. Ensure the oil level in the crankcase is adequate by adding oil if needed. Clear any obstructions from the cooling fins and air passages. Replace any pitted, fouled, or incorrectly gapped spark plugs. Make sure the vent in the fuel cap is open. Finally, check for dirt in the fuel filter and replace it if necessary. Also, verify that you are using the correct fuel type; if not, drain the tank and replace with the proper fuel.

  Uneven cutting height on your Toro Lawn Mower can be caused by dull or bent blades; sharpen the blades or install new ones. Ensure the mower is level from side-to-side and front-to-rear. Adjust the anti-scalp wheel height if it's not set correctly. Clean the underside of the mower deck, and adjust the tire pressure as needed.

  Gerald NortonAug 17, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken drive belt, in which case you should install a new one. Another possibility is that the drive belt has come off the pulley; reinstall it and check the adjusting shafts and belt guides for the correct position. Also, the mower belt may be worn, loose, or broken, requiring a new mower belt.

  If the starter on your Toro Lawn Mower doesn't crank, make sure the blade control (PTO) is disengaged. Ensure the parking brake is engaged by moving the motion control levers to the brake position, and that you are seated on the seat. Check if the battery is dead and charge it if necessary. Inspect the electrical connections for corrosion or looseness and ensure good contact. Also, verify if a fuse is blown and replace it if needed.
