Spectrum SW420-Expert · product viewHigh-output scarifying and aeration
A two-cassette petrol machine for intensive lawn renovation.
The SW420-Expert combines a 212cc OHV engine with dedicated scarifying and aerating cassettes. Six working-depth settings and a 45-litre collector support controlled treatment of moss, thatch and compacted turf.
Aerating tine cassette
Use thirteen sets of tines to open the turf and support root development.
High-output petrol engine
The listed 4.5kW output is intended for more demanding renovation than light electric units.

Power unit
212cc OHV engine
The air-cooled four-stroke engine provides the listed 4.5kW output.
Working depth
Six-stage adjustment
Set the working depth to match light aeration or more intensive scarification.
Cassettes
Scarifying and aerating systems
Switch the complete cassette rather than asking one mechanism to perform both jobs.
Working modes
Separate scarifying and aerating into deliberate operations.
Use the scarifier to remove restrictive material, then aerate only when soil and turf conditions justify additional penetration.
Scarify
Lift moss and thatch from the surface and collect loosened material.
Aerate
Use the tine cassette to improve exchange of air, water and nutrients.
Collect
The 45-litre bag reduces manual raking after a pass.

Ownership planning
The purchase decision continues beyond the specification sheet.
Plan aftercare
Renovation can expose soil and thin turf, so plan seed, feed and watering where appropriate.
Test before full use
Start shallow and verify the result before making deeper passes.
Clean after use
Remove compacted debris and inspect the working parts before storage.
