The Automower 450X NERA is a robot mower for large lawns: the stated working area is 5,000 m² (±20%). It works inside a buried boundary wire, so installation requires preliminary work along the edge of the lawn. It handles slopes up to 50% inside the area and up to 25% at the boundary, with electrically adjustable cutting height. One charge gives about 145 minutes of mowing and recharging takes 40 minutes. Lift and tilt sensors detect when the mower is raised or inclined, and it is controlled through the Automower Connect app. Theft protection includes a PIN code, GPS tracking and geofence (a virtual perimeter). Cutting is done by three pivoting razor blades, which are replaced at regular intervals.

Technical specifications

How it works
Parameter	Value	Source
Working area capacity	5000 m² This is the area the mower covers in ideal conditions, and manufacturers state it with a tolerance (Husqvarna prints ±20%). A garden split into several zones, with trees or narrow passages, costs more than the square metres suggest: choose with headroom rather than at the limit.	Compiled by editorial team

Number of blades	3	Compiled by editorial team
Maximum slope	50 % Measure the slope at the steepest point of the lawn, not on average, and remember the declared figure assumes dry grass in ideal conditions. If the lawn comes close to this value you need headroom: a mower at its limit slips and leaves strips of uncut grass.	Compiled by editorial team
Maximum slope at boundary	25 %	Compiled by editorial team

Boundary wire required	Yes «No boundary wire» does not mean «no installation»: satellite models need an antenna placed where it can see the sky, and under tree canopies or next to a high wall the signal can drop out. The wire goes away, the site survey does not.	Compiled by editorial team

Noise
Parameter	Value	Source
Guaranteed sound power level	58 dB(A) This is the guaranteed sound power level (LWA) that makers of outdoor machinery must declare in Europe: it measures how much noise the machine emits, not how much is heard a few metres away. It cannot be compared with the decibels of home robots, which are a sound pressure level.	Compiled by editorial team
