  If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, make sure you are sitting on the seat and the parking brake is engaged. Check that the fuel tank is filled with gasoline and the choke lever is set to ON. You may also need to clean or replace the air cleaner element, install the wire(s) on the spark plug(s), install a new, correctly-gapped spark plug(s), or replace the fuel filter.

  An uneven cutting height with your Toro Lawn Mower can occur due to several reasons. The blades might not be sharp, requiring you to sharpen them. Bent cutting blades should be replaced. Ensure the mower is level from side to side and front to rear. A dirty mower underside needs cleaning. Incorrect tire pressure should be adjusted. If the blade spindle is bent, contact an Authorized Service Dealer.

  If your Toro Lawn and Garden Equipment engine won't start, starts hard, or fails to keep running, there are several things to check. Make sure you're seated and the parking brake is engaged.

Why is my Toro Lawn Mower vibrating abnormally?
- C
  Cynthia BellSep 4, 2025
  Abnormal vibration in your Toro Lawn Mower can stem from several sources. It might be due to bent or unbalanced cutting blades, which necessitates installing new ones. Alternatively, check if the blade mounting bolt or engine mounting bolts are loose and tighten them accordingly. Also, inspect the engine pulley, idler pulley, or blade pulley for looseness and tighten if needed. If the engine pulley is damaged or the blade spindle is bent, it is recommended to contact an Authorized Service Dealer.

What to do if the blades on my Toro 30612 Lawn Mower won't rotate?
- N
  Natalie GarrisonSep 6, 2025
  If the blades of your Toro Lawn Mower are not rotating, the possible causes are: * A worn, loose, or broken drive belt, which requires a replacement. * The drive belt is off the pulley, so it should be reinstalled, and the traction unit idler pulley, idler arm, and spring should be checked. * A worn, loose, or broken deck belt, which also requires a replacement. * Too loose deck idler pulley tension, which can be fixed by repositioning the spring anchor on the deck. * The deck belt is off the pulley, so it should be reinstalled, and the idler pulley, idler arm, and spring should be checked.
