What to do if my Toro Lawn Mower starter does not crank?
- J
  John JohnsonAug 7, 2025
  If the starter on your Toro Lawn Mower isn't cranking, it could be due to several reasons. First, ensure that the blades (PTO) are disengaged by shifting the blade control lever. Next, make sure the parking brake is engaged. A dead battery, corroded or loose electrical connections, or a blown fuse could also be the cause. You can try charging the battery, checking the electrical connections, and replacing the fuse. If the issue persists, it may be due to a damaged relay or switch, in which case you should contact an Authorized Service Dealer.

How to troubleshoot a Toro Wheel Horse 16-38XL Lawn Mower engine that loses power?
- S
  Shelby MyersAug 12, 2025
  If your Toro Lawn Mower engine is losing power, consider these possible causes: The engine load might be excessive, so shift to a lower gear to reduce ground speed. A dirty air cleaner, low oil level, or plugged cooling fins and air passages can also cause power loss; clean the air cleaner, add oil, and remove any obstructions. Other potential issues include a faulty spark plug (replace it), a plugged fuel cap vent hole (clean or replace the cap), or a dirty fuel filter (replace it). If the problem persists, it could be due to dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

  Uneven cutting height on your Toro Lawn Mower can be caused by incorrect tire pressure, an unlevel mower, or a dirty mower underside. Ensure that you set the tire pressure correctly and level the mower from side-to-side and front-to-rear. Cleaning the underside of the mower can also help.

  Barbara JohnsonAug 25, 2025
  Abnormal vibration in your Toro Lawn Mower can stem from several issues. The cutting blades might be bent or unbalanced, requiring replacement. Check if the blade mounting bolt or the engine mounting bolts are loose and tighten them. Also, inspect the engine pulley, idler pulley, or blade pulley for looseness and tighten as needed. If the engine pulley is damaged, contact an Authorized Service Dealer.

What to do if the blades on my Toro Wheel Horse 16-38XL do not rotate?

  Maureen ParkAug 29, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it's likely due to a worn, loose, or broken blade drive belt, which will need to be replaced. Another possibility is that the blade drive belt has come off the pulley; in this case, reinstall the belt and check the idler pulley and belt guides for correct positioning.
