What to do if my Toro Lawn Mower will not mulch grass?
- S
  Shawna BarnesAug 21, 2025
  If your Toro Lawn Mower isn't mulching grass effectively, make sure the throttle control is in the FAST (rabbit) position. Avoid mowing when the grass is wet; wait until it's dry. If the grass is excessively high, mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting swath. Also, ensure that the blade is sharp; sharpen or replace it if necessary.

  Denise DouglasAug 23, 2025
  If your Toro Lawn Mower engine is running erratically, try these steps: Push the CHOKE control in (if equipped) or move the throttle control out of the CHOKE position. Connect and tighten the spark plug wire(s). Clean the fuel line and fill the tank with clean, fresh gasoline (less than 30 days old). Replace the fuel filter, if equipped. Clear the vent or replace the cap if damaged. You may also need to drain the fuel tank and refill it with fresh gasoline. Lastly, replace the air cleaner cartridge/element or clean the pre-cleaner, if equipped.

Why Toro Lawn Mower has an uneven cut?
- C
  Christopher AriasAug 30, 2025
  If your Toro Lawn Mower is leaving an uneven cut, it could be due to several reasons. The deck might not be balanced properly, so perform a side-to-side deck adjustment. A dull blade can also cause this issue, so sharpen or replace the blade. Finally, check the tire pressure in all four tires to ensure they are even.

  If your Toro Lawn Mower engine is overheating, it could be due to a couple of reasons. First, check the engine oil level and fill the crankcase to the proper capacity with the correct weight of oil. Second, ensure that the airflow isn't restricted by cleaning any grass clippings and debris from around the engine’s cooling fins and blower housing.
