The 420iQ brings Husqvarna’s EPOS reference-station approach to a full-acre residential class. It can eliminate perimeter cable while retaining a dedicated positioning system, but the RS1 site and visibility requirements should be planned before assuming the installation is wire-free in every practical sense.
Measure only mowable grass, not total lot size. Map disconnected zones and the narrowest passage. Check the steepest working grade rather than the yard’s average. For satellite-guided machines, assess tree and building cover; for wired models, plan the dock and perimeter route before purchase.
