  Theresa WallaceAug 19, 2025
  Your Toro Lawn Mower's starter might not crank due to several reasons. It could be because the blade control (PTO) is engaged, so move it to disengaged. The parking brake might not be on, so set it. Ensure you are seated on the seat. The battery could be dead, so charge it. Check electrical connections for good contact if they are corroded or loose. A blown fuse could also be the culprit, so replace it.
