Husqvarna Automower 420 iQ Wire-Free Robotic Lawn Mower – 1 Acre

EPOS Robotic Lawn Mower for Lawns Up to 1 Acre

The Husqvarna Automower® 420 iQ is a premium wire-free robotic lawn mower designed to autonomously maintain residential lawns up to 1 acre.

Built specifically for American lawns, the 420 iQ combines Husqvarna EPOS® satellite positioning, virtual boundaries, radar obstacle detection, systematic pattern mowing, app-controlled electric cutting height, GPS theft tracking, cellular connectivity, and automatic charging into one autonomous lawn-maintenance system.

There is no perimeter wire required for an EPOS installation. Instead, mowing areas, virtual boundaries, pathways, and stay-out zones are created digitally through the Automower® Connect app.

Even better, the Husqvarna EPOS® RS1 Reference Station is included with the 420 iQ. Husqvarna Cloud EPOS is also available in select locations, which may allow installation without using the physical reference station.

MSRP: $3,299.99

Husqvarna Automower 420 iQ at a Glance

These specifications match Husqvarna's current U.S./Canada SKU 970 72 75-01.

Designed to Maintain Up to 1 Acre

The Husqvarna 420 iQ doubles the systematic mowing capacity of the 410 iQ, making it the better fit for larger residential properties.

Husqvarna rates the 420 iQ for:

Systematic Mowing

Up to 1 acre

Irregular / Random Mowing

Up to 0.5 acre

Systematic mowing allows the mower to work in organized patterns rather than relying on random movement, substantially increasing the amount of lawn it can efficiently maintain.

For properties approaching an acre, Automation Hub recommends calculating actual mowable acreage rather than total lot size.

A 1.25-acre property, for example, may have considerably less than one acre of grass after accounting for the house, driveway, pool, landscaping, woods, patios, and other non-mowable areas.

Wire-Free Mowing with Husqvarna EPOS®

The Automower 420 iQ can eliminate buried perimeter wire entirely.

Husqvarna's Exact Positioning Operating System (EPOS®) uses satellite positioning and correction data to determine the mower's location and establish virtual boundaries.

Instead of burying wire around your property, you can digitally configure:

• Mowing areas
• Virtual boundaries
• Stay-out zones
• Pathways
• Cutting patterns
• Mowing schedules

If your landscaping changes, the virtual map can be modified without digging up or relocating boundary wire.

EPOS RS1 Reference Station Included

The EPOS RS1 Reference Station is included with the 420 iQ.

The current U.S. package includes both the RS1 Reference Station and EPOS Plug-in, so the hardware needed for a traditional EPOS virtual-boundary installation isn't an additional mower purchase.

This is particularly important when comparing robotic mowers because RTK or satellite correction hardware is not always included with competing systems.

Husqvarna Cloud EPOS

Husqvarna now offers EPOS via Husqvarna Cloud in select locations.

If your property has compatible Cloud coverage, the mower may use Husqvarna's Cloud-based correction service instead of requiring installation of the included physical RS1 reference station.

If Husqvarna Cloud covers your property:

A Cloud-based installation can provide a simpler wire-free setup.

If Cloud coverage isn't available:

The included RS1 reference station can be installed.

Automation Hub can help determine which EPOS installation method makes the most sense for your property.

Systematic Pattern Mowing

The 420 iQ can mow your lawn in organized patterns rather than only traveling randomly.

Available pattern options include:

• Parallel / striped
• Checkerboard
• Triangle
• Random mowing

That gives homeowners more control over the appearance of the finished lawn while also allowing the mower to cover larger areas more efficiently. Husqvarna specifically highlights systematic mowing as the technology enabling the 420 iQ to maintain its full 1-acre capacity.

Handles Slopes Up to 45%

The Automower 420 iQ is rated for slopes up to:

45% Grade

That's approximately 24° inside the mowing area.

Husqvarna rates maximum slope performance at the boundary at 15%.

The mower's larger wheels and rugged bumper are designed to help it navigate:

• Hills
• Rolling lawns
• Surface transitions
• Driveways
• Paths
• Uneven terrain

A compatible Husqvarna iQ Series Terrain Kit is also available for properties requiring additional traction.

1–4 Inch Electric Cutting Height

The 420 iQ provides a particularly useful feature for American lawns:

1–4 Inch Cutting Height

The cutting height is electronically adjustable, allowing changes through the mower's controls or Automower Connect app.

The broad range allows the 420 iQ to accommodate different turf varieties, seasonal conditions, and homeowner preferences.

9.4-Inch Cutting System

The 420 iQ uses a 9.4-inch cutting system with three pivoting razor blades.

Instead of allowing grass to grow tall and removing a large amount once per week, Automower is designed to mow frequently, removing small amounts of growth at a time.

The mower also supports dual cutting direction, helping distribute blade wear.

Radar Obstacle Detection

The 420 iQ incorporates radar object detection.

Radar works alongside the mower's navigation system to help identify obstacles and improve autonomous navigation around objects within the lawn.

This is particularly useful in residential environments where objects in the mowing area may change from day to day.

84-Minute Mowing Time & Faster Charging

Husqvarna currently specifies:

Typical Mowing Time

84 minutes

Typical Charging Time

54 minutes

When charging is required, the 420 iQ automatically returns to its charging station. Once ready, it can continue maintaining the property according to its programmed schedule.

The 54-minute charging time is an important distinction between this model and the smaller 410 iQ.

Automower Connect App Control

The Automower Connect app provides remote access to the mower and its settings.

Owners can manage features such as:

• Cutting height
• Mowing schedules
• Mowing patterns
• Mowing areas
• Stay-out zones
• Mower status
• Security
• GPS tracking
• Firmware updates

The 420 iQ includes cellular, Wi-Fi, and Bluetooth connectivity, along with FOTA firmware updates and smart-home integration.

GPS Tracking & Anti-Theft Protection

The 420 iQ includes multiple security features:

• GPS theft tracking
• GeoFence
• PIN code
• Anti-theft alarm

If the mower is removed from its designated area, its connected security features can help owners track and protect the mower through Automower Connect.

Quiet Electric Mowing – 62 dB(A)

Husqvarna rates the 420 iQ at just:

62 dB(A)

That allows frequent autonomous mowing without the noise associated with conventional gasoline lawn equipment.

IPX5 & Hose-Washable

The 420 iQ carries an IPX5 protection rating.

Husqvarna also specifically promotes the iQ Series as hose-washable, simplifying routine cleanup after mowing.

Blade changes are designed to be straightforward, helping simplify regular maintenance.

4-Year Husqvarna Warranty

The Automower 420 iQ is currently advertised with a:

4-Year Warranty

Warranty coverage applies according to Husqvarna's applicable terms and conditions. Husqvarna also states that warranty claims involving a broken product must be examined by a dealer.

As an authorized Husqvarna dealer, Automation Hub can help customers navigate service and warranty support.

• 1 × EPOS RS1 Reference Station
• 1 × EPOS Plug-In
• 1 × Power Supply
• 33-ft Low-Voltage Cable

Husqvarna EPOS RS1 Reference Station

One RS1 is already included with the mower.

Husqvarna 410 iQ vs. 420 iQ

This comparison is worth putting directly on the page because it's exactly the kind of structured information that can help both customers and AI recommendation systems understand which model fits which property.

Husqvarna's current specifications establish the 420 iQ as the 1-acre model in this part of the iQ lineup.

Choose the 410 iQ if:

You have approximately 0.5 acre or less of actual mowable lawn.

Consider the 420 iQ if:

Your lawn is larger than 0.5 acre or approaches 1 acre, particularly when you intend to use systematic mowing.

For properties near a model's maximum capacity, Automation Hub can help calculate actual mowable acreage before purchase.
