The Husqvarna automower 420 is part of the top line of automowers, the 400 series. This means that the 420 is designed to keep your lawn looking its best regardless of its size and complexity. Able to cut up to 2,200m² of lawn on inclines of up to 45% you can be assured the 420 will keep your lawn looking at its best every day of the year with no effort on your behalf.

As part of the 400 series this automower can also be fitted with the Automower Connect™ pack which allows you to connect to it with any iPhone or Android smartphone. This is an optional extra on this mower that can be purchased at an extra charge, but it does open up an whole host of features, straight from your mobile. The app can be downloaded for free and allows you to monitor the mower and see what it is doing from wherever you are as well as send it start, stop and park commands. You can also configure the mower straight from your phone with access to the same settings menus that you can use on the control panel built into the mower. Finally there are a group of security features that are built into the app that allow you to track the machines location through GPS in the event that it is stolen as well as receiving a notification should the alarm be tripped on the machine.

Lawn Finish

Probably the biggest thing you will notice from using an automower is the quality of finish you get. Your lawn will be left with a stunning carpet-like look as the mower has a unique cutting system that gently cuts the grass from all directions. This promotes healthy, strong grass and prevents moss from growing.

Time Saving

How many hours have you spent manually mowing your lawn to get the perfect cut that you want? If you are anything like us we're guessing a lot. The automower will go out and cut your lawn automatically day after day giving you a perfect lawn with no effort from you (that's why we now have one cutting our lawn outside the showroom). While it's busy giving you a beautiful lawn you can get on with some other work, spend some time with the family or even just put your feet up and make a cup of tea.

Random Cutting

The random cutting concept is an idea Husqvarna built into their automowers to mimic sheep. Sheep create greener grass by grazing little and often over a patch of grass. By cutting a little each day and letting the clippings fall back into the grass the nutrients and moisture are returned to the ground promoting a healthy lawn.

With some clever programming the automower constantly mows in a random pattern while ensuring that all ground has been covered. You define the area that the mower works in by easily laying down a boundary line which can be embedded into the soil around the perimeter of your lawn.

Functions & Security

The automower is designed with sensors that allow it to work around trees, brushes and even flowerbeds. Rain won't stop your lawn being cut either as the automower can work in all but the most extreme conditions.

When the battery is running low or it has finished its cutting for the day the automower returns to its charging station. Security isn't an issue either as you set up a pin number for the mower that allows only you to change what the mower is doing and the is an alarm that will sound if someone tries to move the mower.
