The catch
Husqvarna Automower 430X
You take on extra work installing and repairing the perimeter loop.
Side by side
Husqvarna Automower 430X vs 420 iQ: 430X sticks with installed boundaries, and 420 iQ adapts when the yard layout changes
Quick verdict
Under heavy tree cover, an installed wire gives a durable boundary, which makes the 430X a fit for a stable lawn. For layouts that change, the 420 iQ works better because EPOS zones can be revised in the app.

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 430X
Does not work with your numbersIts rating covers 0.8 acre and 45% grades inside the boundary, and it needs a boundary wire. 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.
