Possible Causes
Worn gear teeth in wheel gearbox, Foreign object inside wheel hub, Cracked wheel rim, Loose wheel on axle
How to Fix / Troubleshooting
Safety first: Turn OFF the mower and lift it carefully by the handles.
- Identify the side: Manually rotate each wheel to determine which side makes noise.
- Remove wheel: Take off the noisy wheel and inspect the hub for stones or debris.
- Check gearbox play: With the wheel removed, gently rotate the gearbox output shaft. Excessive play or roughness indicates internal wear.
- Replace components: Replace the wheel if cracked. If the gearbox is noisy or rough, replace the complete drive motor/gearbox assembly.
Operating with a damaged gearbox can lead to sudden loss of drive or further damage to the mower.
