    Why Gardena Lawn Mower is outside working area?
    • W
      William JonesAug 23, 2025
      If your Gardena Lawn Mower is operating outside the designated working area, it could be due to a few reasons: * The boundary wire connections to the charging station may be crossed. Ensure the boundary wire is connected correctly. * The boundary wire might be too close to the edge of the working area. Verify that the boundary wire has been laid according to the instructions. * The robotic lawnmower may be struggling to differentiate the signal from a nearby installation. Try placing the robotic lawnmower in the charging station and generating a new loop signal.

      If your Gardena Lawn Mower is trapped, it means it has gotten caught on something or is stuck behind multiple obstacles. To resolve this: * Free the robotic lawnmower from whatever it's caught on and address the reason it became trapped in the first place. * Inspect the area for obstacles that might be hindering the robotic lawnmower's movement.

    Why Gardena Lawn Mower has uneven mowing results?
    • K
      Karen ToddAug 28, 2025
      Uneven mowing results with your Gardena Lawn Mower can stem from several factors: * The robotic lawnmower may not be working enough hours per day. Increase the working times. * The working area's shape may require manual adjustments for the robotic lawnmower to reach all remote areas. Use Lawn coverage to guide the robotic lawnmower to these areas. * The working area might be too large. Consider limiting the working area or extending the working time. * The blades could be blunt. Replace all blades and screws to ensure balanced rotation. * Grass accumulation near the blade disc or around the motor shaft. Check that the blade disc skid plate rotates easily. If not, unscrew the blade disc and remove any grass or foreign objects.

    Why Gardena Lawn Mower has no drive?
    • C
      Crystal HunterAug 30, 2025
      If your Gardena Lawn Mower is showing 'No drive', there could be a few reasons: * The robotic lawnmower may have gotten caught on something. Free it and address the cause. If wet grass is the issue, wait for the lawn to dry. * The working area might include a steep slope. The maximum guaranteed slope is 35%. Isolate steeper slopes. * The guide wire may not be angled correctly on a slope. If the guide wire is on a slope, it must be laid at an angle across it.

      Trevor ClarkeSep 1, 2025
      If your Gardena Lawn Mower is running at the wrong time, it's likely due to: * The robotic lawnmower clock needs to be set. Set the clock. * Incorrect start and stop times for mowing. Reset the start and stop time settings for mowing.
