How to Fix / Troubleshooting
Safety: Turn OFF the mower, disconnect from dock, and wear gloves.
- Identify source: Tilt the mower carefully and locate whether the leak is from a drive wheel gearbox or the cutting motor area.
- Clean area: Wipe away leaked grease to inspect for cracks or loose screws.
- Check wheel play: Wiggle the affected wheel; excessive play suggests internal wear.
