Plug in your numbers
Can either mower handle your yard?
This checks hard limits only. Personal preferences are left out of the math.
Husqvarna Automower 410 iQ
Works with your numbersIts rating covers 0.5 acre and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Husqvarna Automower 420 iQ
Works with your numbersIts rating covers 1 acre mowing systematically (0.5 acre mowing irregularly) and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
The area check uses the published maximum with no reserve added. When a systematic mowing rating is shown, the mower has to follow that pattern to reach the maximum area. Slopes at the boundary can have a lower limit than the interior. You still need to check trees, gates and separate zones.
