Kawasaki FJ180 KAI Engine
The W520 is powered by a Kawasaki FJ180 KAI commercial-grade engine. Husqvarna rates the engine at 4.6 HP, with a displacement of 10.9 cu. in. The engine uses air cooling and full-pressure lubrication with an oil filter.
The 4.6 HP figure is the power rating supplied by the engine manufacturer, rather than a measurement of power delivered at the wheels or cutting blade.
This gasoline engine gives the W520 the advantage of quick refueling and eliminates the need to manage battery charging between mowing sessions.
20-Inch Aluminum Cutting Deck
The W520 features a 20-inch aluminum cutting deck. Aluminum construction provides a useful combination of durability and reduced weight, making the mower easier to maneuver than many heavier steel-deck commercial machines.
The cutting system offers nine height positions, with a minimum cutting height of approximately 1.5 inches and a maximum of approximately 4.5 inches. The central adjustment mechanism allows the operator to change the deck height without adjusting individual wheels separately.
Three Cutting Methods
The W520 can be configured for:
- Grass collection – Collects clippings in the supplied high-capacity catcher.
- BioClip® mulching – Finely cuts grass clippings and returns them to the lawn when the optional BioClip® equipment is installed.
- Rear discharge – Discharges grass clippings behind the mower when the grass catcher is removed.
Husqvarna lists the BioClip® kit and BioClip® plug as accessories, rather than standard included equipment.
Variable-Speed Self-Propelled Drive
The W520 uses rear-wheel-drive self-propulsion with variable speed. The documented model provides a forward speed range of approximately 2.2 to 3.7 mph.
This allows the operator to slow the mower when working through dense grass or around obstacles and increase the pace when covering open areas.
The aluminum-case transmission is designed to provide a durable drive system for users who regularly operate the mower.
Blade Brake Control
One of the W520's useful professional features is Blade Brake Control (BBC).
BBC allows the operator to stop the cutting blade while leaving the engine running. This can be useful when the operator needs to temporarily stop mowing without shutting down the gasoline engine completely.
Durable Commercial Construction
The W520 is built around a cast-aluminum chassis with a side protection bumper. Husqvarna describes the chassis as designed for longer service life, making the mower suitable for demanding professional applications.
The mower also uses aluminum rims and wheel bearings on both the front and rear wheels, helping provide smooth movement and durability during repeated use.
High-Capacity Grass Collection
For users who prefer a clean, finished lawn, the W520 includes a 2.3 cu. ft. fabric grass collector with a dust blocker. Its relatively large capacity reduces the frequency of emptying compared with smaller collection bags.
The catcher can be removed when rear discharge is preferred.
Operator Comfort and Convenience
The W520 incorporates an ergonomic handlebar with a soft grip to make prolonged mowing more comfortable. The handle height is adjustable in two positions, and the handle folds down for easier transportation and storage.
The mower also includes a throttle control, allowing the operator to regulate engine speed according to operating requirements.

Why Choose the Husqvarna W520?
The W520 is designed for users who need more than a basic residential push mower. Its commercial-grade Kawasaki engine, aluminum chassis, aluminum transmission case, self-propelled drive, and BBC blade control give it a professional-oriented specification package.
The 20-inch deck keeps the mower maneuverable, while the 2.3 cu. ft. collector provides useful capacity when a clean, collected finish is desired. Variable-speed propulsion also allows the operator to select a comfortable working pace.
Ideal For
- Professional lawn-care operators
- Property-maintenance crews
- Commercial landscaping applications
- Large residential lawns
- Users who prefer gasoline-powered equipment
- Applications requiring frequent grass collection
- Properties with obstacles where a compact 20-inch mower is advantageous
What's Included?
The W520 970 62 16-01 is supplied as a complete gasoline-powered mower with its grass-collection equipment. Husqvarna specifically identifies the following as not included:
- BioClip® kit
- BioClip® plug
These components are available separately for users who want to use the mulching function.
Product Identification Note
For replacement parts, accessories, and service information, use the exact W520 SKU (970 62 16-01) when possible. Husqvarna's support documentation shows that the W520 name has been used for more than one SKU, so specifications such as engine configuration and equipment should be matched to the exact model number rather than assumed from the W520 name alone.
