What causes abnormal vibration in my Toro 74253 Lawn Mower?
- LLori MartinezSep 7, 2025
Abnormal vibration in your Toro Lawn Mower can stem from several issues. The cutting blade(s) may be bent or unbalanced, requiring replacement. The blade mounting bolt could be loose, so tighten it. Also, check if the engine mounting bolts are loose and tighten them if necessary. A loose engine pulley, idler pulley, or blade pulley can also cause vibration, so tighten the appropriate pulley. For issues like a damaged engine pulley, bent blade spindle, or loose/worn motor mount, contact an Authorized Service Dealer.
