  Michele HarrellAug 25, 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 drive belt. Another possibility is that the drive belt is off of the pulley; install the drive belt and check the adjusting shafts and belt guides for the correct position. Finally, the mower belt might be worn, loose, or broken, so install a new mower belt.
