  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.

  If the starter on your Toro Lawn Mower isn't cranking, check these items: 1. Ensure the blade control switch is disengaged. 2. Confirm the motion control levers are in the park position. 3. Make sure you are seated on the seat. 4. Check the battery charge and charge if necessary. 5. Inspect the electrical connections for corrosion or looseness and ensure good contact. 6. Examine the fuse and replace it if blown. If these steps don't resolve the issue, a relay or switch may be damaged, and you should contact an Authorized Service Dealer.

  Nina CobbAug 28, 2025
  Your Toro Lawn Mower engine may be losing power due to: * Excessive engine load. Try reducing ground speed. * A dirty air cleaner. Clean the air cleaner element. * Low oil level in the crankcase. Add oil to the crankcase. * Plugged cooling fins and air passages. Remove any obstructions. * Faulty spark plug(s). Install a new, correctly gapped spark plug(s). * A closed vent in the fuel cap. Open the vent. * Dirt in the fuel filter. Replace the fuel filter. * Incorrect fuel in the fuel tank. Drain the tank and replace with the proper type. If the problem persists, there may be dirt, water, or stale fuel in the fuel system. In this case, it's best to contact an Authorized Service Dealer.

Why my Toro Lawn Mower doesn't move?

  Steven FordSep 3, 2025
  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.
