Robot mower vibrates excessively, with noticeable shaking and rattling while cutting.

Safety first: Turn OFF the mower and wear gloves before working near the blades.

• Check blade count: Ensure all blade positions on the disc are filled with identical Flymo blades and screws.
• Remove debris: Clean any mud or grass clumps from the disc, especially if concentrated on one side.
• Inspect disc: Spin the disc by hand and look for wobble. A bent disc should be replaced.
• Test again: After balancing the disc, run the mower on a flat area and observe for reduced vibration.
