  Drew RoweAug 1, 2025
  If your Stihl Lawn Mower cuts out, it could be due to the battery or machine's electronics overheating (remove the battery and allow both to cool down), an electrical or electromagnetic malfunction (remove and refit the battery), mowing overlong grass or at too low a cutting height (allow the machine to cool down and adjust the cutting height), having the feed speed too high (allow machine to cool down, reduce speed), or dirty cooling inlets (allow machine to cool down, clean cooling air openings in motor housing).
