Weather-timer & innovative technologyWeather-timer & innovative technology

Weather-timer & innovative technology

The weather timer makes it possible for the Automower 420 to automatically adjust its working intervals to the weather and grass growth. This allows the robot mower to increase its working time on wet and rainy days and reduce it on sunny or dry days. The robust blades do not cut much at once, but thanks to its daily trips they cut regularly and thus ensure a healthy lawn.

Automower Connect@HomeAutomower Connect@Home

Automower Connect@Home

Thanks to the standard Connect@Home module, the Husqvarna 420 robot lawn mower can be controlled using a smartphone via a Bluetooth connection. To use this feature, you and the robot must be in close proximity.

For the complete use of the app functions, such as on-the-go control, theft alarm and GPS-based navigation, the optional Automower Connect module must be retrofitted (see customer options).

The innovative cutting system from Automower 420

The robot grass cutter does not cut off much of the blades of grass every time but mows regularly. This guarantees a nice and healthy lawn. It is equipped with three razor-sharp blades that are mounted on a cutting disc. This ensures an efficient mowing process and at the same time low energy consumption.

Thanks to the innovative mowing system and a noise level of just 58 dB the robot lawn mower works very quietly and particularly energy efficient in ECO mode. The cutting height of the robot mowercan be adjusted electrically to the desired value between 20 and 60 mm.


Timer for an automatic mowing operation

The Husqvarna Automower 420 can be operated, controlled and programmed via a large, high-resolution display. If a timetable has been set for the robot lawn mower, it follows the schedule completely independently.

When the battery level is low, or after it has completed its mowing task, the robot grass cutter returns to its charging station to recharge. To locate the charging station, the robot mower can choose from four different navigation options.


Automatic passage detection

The Husqvarna Automower 420 is equipped with an automatic passage recognition, enabling it to detect narrow passages. It then adjusts its navigation accordingly to the prevailing conditions and passes through narrow corridors skilfully and efficiently. This means that hard-to-reach areas in the garden are no problem for the Automower 420.


Husqvarna Automower 420 offers a remote start function

It is possible to define up to five different starting points for the robot mower. This allows the robot lawn mower to reach even remote areas in your garden. This function ensures consistent, uniform processing of all surfaces (including ancillary areas), and thus an even lawn appearance.


Weather timer for an optimized mowing frequency

The weather timer of the Husqvarna 420 allows an optimized mowing frequency, which is adapted to grass growth in the garden. This means that the robot mower reduces its operation during dry periods and increases it when it rains. The lawn thus receives exactly the care it needs.


Obstacle, lift and tilt sensors ensure safety

Equipped with different sensors, the robot lawn mower reacts accordingly to changes. The built-in obstacle, lifting and inclination sensors ensure safe operation of the robot mower. The PIN code and alarm feature protect Husqvarna Automower against theft and make it childproof.


Colourful case cover

The cover of the robot grass cutter Husqvarna 420 can be removed and replaced with a different colour.
