Automower 410iQ
Rated for 0.5 acres and 45% grade — that is 24.2°, not 45°. On a real lawn, once you allow for borders and travel paths, plan on about 0.4 acres.
What it handles
Two-wheel drive, which caps how steep it can work. That covers rolling ground, but not a bank you would struggle to walk up.
Navigation is satellite-based without vision or LiDAR, so heavy tree cover is a real risk — it loses its fix under canopy.
If your ground is steeper
These are rated for a similar area but hold more grade than the Automower 410iQ’s 45%.
How confident we are
Cross-checked against the manufacturer and at least one other source.
Area 0.5 acre from the "Lawn Size (+/-20%)" row on husqvarna.com/us - the same row the 420iQ 1.0 acre comes from, so the two stay comparable. Irregular-lawn capacity is 0.25 acre. Slope 45 PERCENT (24.2 deg) inside the installation, but only 15% at a virtual boundary. SKU 970727401. Dealer network, not online retail.
