Worn blade motor bearings, Loose cutting disc, Foreign object trapped under deck, Worn wheel motor gearbox

How to Fix / Troubleshooting

Safety first: Turn OFF the mower and disconnect battery if possible. Never place hands near blades while powered.

Steps to check:

  • Inspect underside: Turn the mower over and look for stones, branches, or toys lodged near the blades or wheels. Remove carefully.
  • Check blade disc: Ensure the cutting disc mounting bolt is tight and the disc is not wobbling.
  • Spin test: Rotate the cutting disc and wheels by hand. Listen for grinding or roughness that indicates bearing or gearbox wear.
  • Replace worn parts: If noise clearly comes from the blade motor area, plan to replace the blade motor assembly. If from a wheel, replace the drive wheel motor assembly.

When to call a technician: Persistent abnormal noise should be investigated by a professional to prevent further damage.
