    • K
      Kathleen ConnerSep 6, 2025
      If your Ryobi Lawn Mower is vibrating at a higher speed, it could be due to an unbalanced or excessively worn blade, which means you should replace the blade. Another possibility is a bent motor shaft. If you suspect this, stop the motor, remove the isolator key and battery, disconnect the power source, and inspect for damage. Have it repaired by an authorized service center before restarting.
