Husqvarna Automower 420 iQ Robotic Mower
Wire-Free EPOS Navigation for New Hampshire Lawns Up to One Acre
About the Husqvarna Automower 420 iQ
The Husqvarna Automower 420 iQ is a wire-free robotic mower built for New Hampshire residential lawns up to one acre. It runs on Husqvarna’s EPOS navigation system (Exact Positioning Operating System), which uses patented RTK satellite technology combined with the national cellular network to deliver centimeter-accurate positioning with no buried perimeter wire.
Setup is done through the Automower Connect app. You drive the mower along your boundary once to map it and define your mowing zones and stay-out areas, and the mower takes it from there.
Seacoast Power Equipment has been serving the seacoast since 1965. We are an authorized Husqvarna dealer in North Hampton, NH, and we carry the Automower iQ Series. Contact us to confirm current availability and to schedule a demo on your property.
Best for: NH residential lawns up to 1 acre with standard terrain and slopes up to 45% (approximately 24 degrees).

One Acre, Done Right: What the 420 iQ Delivers
The 420 iQ is built for the homeowner with a full acre to maintain. One acre of lawn is a real time commitment every week when done manually. The 420 iQ eliminates that entirely.
EPOS delivers centimeter-level positioning accuracy of 2 to 3 centimeters across your full property. The mower knows exactly where it is and mows systematically rather than randomly, producing consistent coverage and clean striping patterns, including parallel stripes, checkerboarding, and triangle designs.
The extended battery supports the additional coverage required for a full acre. Larger wheels and an optimized bumper handle surface transitions, driveways, paths, and grade changes throughout the mowing area. The IPX5 weather rating means the 420 iQ operates in rain without issue. Radar detects obstacles continuously. Physical wire backup can be added for any dead zones with limited satellite coverage, so no corner of your property goes unmowed.
The 420 iQ is part of the Automower iQ Series, recognized by Newsweek as New and Noteworthy for innovation in residential lawn care. Husqvarna has over 25 years of robotic mowing experience and remains the world’s number one selling robotic mower brand by retail value.
