Why Toro Lawn Mower vibrates abnormally?
- TTimothy McdonaldSep 22, 2025
If your Toro Lawn Mower is vibrating abnormally, the cutting blade(s) may be bent or unbalanced, so install new cutting blade(s). Check if the blade mounting bolt is loose and tighten it. Also, ensure the engine mounting bolts are tightened. Inspect the engine pulley, idler pulley, or blade pulley for looseness and tighten the appropriate pulley, checking that idler springs are not over stretched. If the engine pulley is damaged, replace it. A bent blade spindle should also be replaced. Finally, check the motor mount for looseness or wear and inspect the mounting bolts.
