What to do if Husqvarna 420 Lawn and Garden Equipment goes outside working area?
- C
  Courtney MaciasAug 25, 2025
  If your Husqvarna Lawn and Garden Equipment is operating outside the designated working area, it could be due to several reasons. First, ensure that the boundary wire connections to the charging station are not crossed and are connected correctly. Also, verify that the boundary wire isn't too close to the edge of the working area and is laid according to the instructions. If there are disturbances from metal objects or buried cables nearby, try moving the boundary wire. If the mower is struggling to differentiate the signal from a nearby installation, place it in the charging station and generate a new loop signal.

  If your Husqvarna Lawn and Garden Equipment displays 'Guide not found,' it indicates a problem with the guide wire connection. Check that the guide wire connector is properly connected to the charging station. Also, look for any breaks in the guide wire and replace any damaged sections with a new loop wire, splicing it with an original coupler. Finally, make sure the guide wire is properly connected to the boundary wire, using the original connector to splice.

  If the cutting height on your Husqvarna Lawn and Garden Equipment is blocked, it's likely due to grass or another object wrapped around the cutting height adjustment or between the blade disc and chassis.

  If your Husqvarna Lawn and Garden Equipment displays that the charging station is blocked, the contact between the charging strips and contact strips may be poor, and the mower has made multiple charging attempts. Dock the robotic lawnmower in the charging station and check that the charging strips and contact strips make good contact. Also, make sure that there is not an object obstructing the robotic lawnmower.

Why is my Husqvarna Lawn and Garden Equipment slipping?
- A
  Ashley HicksAug 29, 2025
  If your Husqvarna Lawn and Garden Equipment is slipping, it could be due to a few reasons. It may have gotten caught on something; free it and address the cause. If wet grass is the issue, wait for the lawn to dry. If the working area includes a steep slope, remember the maximum guaranteed slope is 45%; isolate steeper areas. If the guide wire is on a slope, ensure it's laid at an angle across the slope.

  If your Husqvarna Lawn and Garden Equipment is showing a low battery, several factors could be at play. First, ensure that the charging station and guide wire are installed correctly.

Finally, check the charging station's indicator lamp for a red flashing light, which could indicate a defective charging station antenna.
