Where the range runs out
The largest Husqvarna we have specs for is the Automower 450XH EPOS at 2.5 acres. Allowing the quarter more that real lawns need for borders and travel paths, that covers 1/4 acre, 1/2 acre, 1 acre, 2 acres. For 3 acres or 5 acres you need another maker.
On grade, the Automower 450XH EPOS tops the range at 45% — 24.2°, not 45°. Rolling ground yes, a bank you would struggle to walk up no.
