How to Fix / Troubleshooting
Safety first: Press STOP and switch OFF before lifting the mower.
- Check wheel condition: Compare tread wear on both wheels. Replace if one is significantly more worn.
- Clean wheel hubs: Remove grass and dirt from around each wheel and axle.
- Test on flat surface: Run the mower on a flat, open area and observe wheel behavior. Listen for unusual noise from one side.
- Swap wheels (if possible): On some models, swapping left and right wheels can help identify if the issue follows the wheel or stays with the motor.
If the mower still pulls strongly to one side, the weaker wheel motor or gearbox should be replaced.
