  Madison ShahAug 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.

  If your Toro Lawn Mower isn't driving, it could be due to several reasons. Check if the bypass valves are open and close them. If that's not the issue, the traction belts might be worn, loose, or broken, or the traction belts are off of the pulleys, or the transmission has failed. In all three cases, contact an Authorized Service Dealer.
