Robot mower leaves patches of uncut grass because the blades are not cutting cleanly.

Safety first: Turn OFF the main switch and wear cut-resistant gloves.

• Inspect blades: Turn the mower on its side and check all pivoting blades on the disc. Replace any that are dull, chipped, or missing.
• Use correct blades: Install genuine McCulloch blades with the sharp edge facing the correct direction as indicated in the manual.
• Check blade screws: Ensure all blade screws are tight but allow the blades to pivot freely.
• Adjust cutting height: If the grass is very tall, raise the cutting height and gradually lower it over several days.
