      Abnormal vibration in your Toro Lawn Mower can stem from several issues. It might be due to a bent or unbalanced cutting blade, which requires a new blade. Alternatively, the blade mounting bolt or engine mounting bolts could be loose, needing tightening. A loose engine pulley, idler pulley, or blade pulley could also be the culprit, so check and tighten them as necessary. If the engine pulley is damaged, contact an Authorized Service Dealer.

      If the blades on your Toro Lawn Mower aren't rotating, the blade drive belt might be worn, loose, or broken, requiring a replacement. The belt could also be off the pulley, in which case you should reinstall it and check the idler pulley and belt guides for correct positioning. Another possibility is that the PTO belt is worn, loose, or broken, which also necessitates a new PTO belt.

The blade slope or blade slope in transport could also be incorrect, requiring adjustment. Additionally, the belt might be worn or damaged, necessitating a new belt. If the pulley is damaged, contact an Authorized Service Dealer.
