In this video, Jason and Glyn from Robot Lawn Mowers Australia address one of the most common problems with the Mammotion Luba 2 robot mower: loud or strange noises coming from the blade system. If your Luba is making unusual sounds after a few days or weeks of use, this step-by-step troubleshooting guide has all the solutions you need!
🔊 Common Noises with the Luba 2 Explained:
Loud vibrations
Blade clipping sounds
Squeals or squeaks during motor startup and shutdown
Grinding or harsh mechanical noises
🛠️ What Causes These Noises?
Loose or cracked blade discs creating imbalance (sounds like a petrol engine!)
Debris stuck between the blade disc and guards
Overused blades wearing screws, leading to blades touching each other
Grass buildup between the mower body and blade guards
Loose center nut on the blade disc collar
✅ How to Fix Luba 2 Noise Problems:
Learn proper blade system cleaning (check out our cleaning tutorial linked in the video!)
Inspect all blades and replace worn or damaged blades (don’t reuse blade screws!)
Tighten the center nut on the blade disc collar for proper balance
Troubleshoot motor bearing noise and how to test the cutting motor
🚨 When to Contact Support:
If the noise persists—such as when bearings are dry or parts are failing—Jason and Glyn explain how to identify these issues and what to do next.
💡 Pro Troubleshooting Tips:
Test your cutting motor in manual mowing mode with and without blade discs.
Identify a failed part if the noise remains with no blade discs installed.
