Robot lawnmower vibrates excessively, especially when the blades are running.

Safety: Turn OFF the mower and wear gloves before touching the blade area.

• Check for missing blades: Ensure all TerraMow blade positions on the disc are populated with blades and screws.
• Inspect for damage: Look for bends or warping in the blade disc. Replace the disc if it is not flat.
• Clean disc: Remove any clumps of grass or mud stuck to one side of the disc that could cause imbalance.
• Tighten screws: Verify that all blade screws are tightened evenly to the recommended torque.
