Engineered to both scarify and aerate your lawn, this robust machine combines powerful performance with user-friendly features to help maintain healthy, vibrant turf over areas up to 2000m². All year round you can use this machine to keep you grass areas well maintained especially after periods of drought, and as we enter the Autumn and Spring periods

Powerful & Efficient Performance

Powered by a 6hp (4.5kW) easy start engine, the SW420-Expert delivers consistent performance to tackle compacted soil and stubborn thatch. Its reliable recoil start system ensures easy ignition every time, allowing you to get to work quickly and efficiently. The machine runs on unleaded petrol

Versatile Scarifying & Aerating Capabilities

This 2-in-1 machine features an impressive 42cm working width and is equipped with 18 robust blades, making short work of dethatching and aerating your lawn. With 6 working height positions ranging from -12mm to +10mm, you can precisely adjust the depth to suit your lawn’s unique needs—ensuring optimal air and water penetration to promote healthier growth.

Blade Engage Function

One of the smart features of the SW420-Expert is its blade engage mechanism. When you’re ready to start scarifying, simply engage the green lever, and the blades/tines will activate. When you need to stop the working cassette—such as when emptying the collector—just release the lever. The engine continues to run, so there’s no need to restart the machine, saving both time and effort. This convenient function adds safety and control to your lawn care routine.

Durable Build & Ergonomic Design

Constructed with a steel deck, the SW420-Expert is built to withstand the rigours of regular use. Its foldable handles with a soft grip not only enhance comfort during prolonged operation but also aid in easy storage. The inclusion of double ball-bearing wheels further improves manoeuvrability, allowing smooth operation over varied terrains.

Efficient Grass & Debris Collection

Equipped with a generous 45-litre debris collector, this scarifier/aerator minimizes downtime by capturing clippings and dethatched material efficiently. This feature helps keep your work area tidy and ensures that you can complete large tasks with fewer interruptions. Where the debris is large many operators use the machine without the collector and clear up on mass.

Ideal for Small to Large Lawns and garden areas 

Designed to tackle lawns up to 2000m², the Spectrum SW420-Expert is perfect for those with expansive outdoor spaces. Its balanced performance and robust design make it a reliable tool for maintaining the health and appearance of your lawn.
