Stihl RLA 240.0
Best OverallPros
- Quiet brushless motor with good torque
- Central height adjustment (5 positions)
- Large collection box (30 litres)
Cons
- Battery and charger sold separately
- Not for very thick thatch on first pass
The Stihl RLA 240.0 is a battery-powered scarifier that uses the AK system, making it compatible with other Stihl garden tools. It has a 32 cm working width and a brushless motor that provides consistent power without the noise and fumes of a petrol model. Owner reviews on retailer sites highlight its ease of use and effective moss removal on medium-sized lawns.
The central height adjustment offers five settings from -12 mm to +6 mm, allowing you to set the depth for light scarifying or more aggressive dethatching. The 30-litre collection box is large enough to reduce emptying frequency, though some users note it can fill quickly on thick lawns. Overall, it is a well-balanced machine that suits most domestic gardens.
Stihl RL 540
Best Budget / CordedPros
- No battery cost or runtime limits
- Lightweight and easy to manoeuvre
- Simple height adjustment
Cons
- Power cord limits range
- Smaller collection box (25 litres)
The Stihl RL 540 is a corded electric scarifier that plugs into a standard household socket. It has a 30 cm working width and a 900 W motor that delivers reliable power for small to medium lawns. Owner feedback on DIY forums indicates it handles light thatch well and is a good entry-level option for those who do not want to invest in a battery system.
This model is lighter than the battery versions at 13 kg, making it easier to lift and store. The height adjustment is manual with three positions, which is less versatile than the RLA range but sufficient for basic scarifying. Users should note that the 25-litre collection box requires frequent emptying on mossy lawns, and the cord can be a nuisance on larger plots.
Stihl RLA 340.0
Best for Large LawnsPros
- Wider 38 cm working width for faster coverage
- High torque brushless motor
- Large 40-litre collection box
Cons
- Heavier than smaller models
- Requires two AK batteries for best runtime
The Stihl RLA 340.0 is a larger battery scarifier designed for bigger lawns. Its 38 cm working width reduces the number of passes needed, saving time on areas over 300 sq m. The brushless motor provides high torque, and the 40-litre collection box is the largest in the Stihl range, meaning fewer stops to empty.
This model is heavier at 17.5 kg, which some users find tiring on uneven ground. It uses two AK batteries (sold separately) to deliver extended runtime, but this also increases the upfront cost. Owner reviews on Amazon UK praise its build quality and the even cut depth across the full width, making it a favourite for serious lawn care enthusiasts.
Stihl RL 640
Best Heavy Duty CordedPros
- Powerful 1200 W motor
- Wide 38 cm working width
- No battery runtime concerns
Cons
- Heavy and less portable
- Cord management can be awkward
The Stihl RL 640 is a mains-powered scarifier with a 1200 W motor and 38 cm working width, making it suitable for heavy thatch removal on large lawns. It offers consistent power without the need for battery charging, which is ideal for users who prefer a simple plug-and-play setup. Owner reviews on Screwfix note its effectiveness on thick moss and compacted thatch.
At 18 kg, this is one of the heaviest models in the Stihl range, and the lack of a self-propelling feature means it requires some physical effort to push. The height adjustment is manual with four positions, offering decent versatility. It is best suited for users with a power socket close to the lawn and who prioritise raw power over portability.
Stihl RLA 240.0 Set
Best Value BundlePros
- Includes battery and charger
- Same performance as RLA 240.0
- Good value for new Stihl users
Cons
- Higher upfront cost than tool-only
- Battery capacity may be limited for large lawns
The Stihl RLA 240.0 Set is the same scarifier as the standalone RLA 240.0 but comes packaged with an AK 30 battery and AL 101 charger. This bundle is ideal for users who are new to the Stihl AK system and do not already own batteries. The set offers a cost saving compared to buying the components separately.
Performance is identical to the standalone model, with the same 32 cm working width and brushless motor. The included AK 30 battery provides enough runtime for a typical medium lawn (around 200 sq m) on a single charge. Owner feedback on Stihl UK's website confirms the set is a popular choice for first-time battery tool buyers.
What to check before buying a Stihl scarifier
Working width is a key factor. A 30-32 cm model is fine for small to medium lawns, while 38 cm suits larger areas. Consider the power source: battery models offer freedom of movement but require investment in batteries and chargers, while corded models provide unlimited runtime but are limited by the power cord length. Weight also matters for ease of use, especially on sloping or uneven ground.
Mistakes to avoid
Do not buy a battery model without checking if you already own compatible Stihl AK batteries. Avoid using a scarifier on wet grass, as it can clog the machine and damage the lawn. Do not set the depth too low on the first pass, as this can scalp the grass and leave bare patches.
FAQs
Can I use a Stihl scarifier on wet grass?
It is not recommended. Wet grass and moss can clog the scarifier and reduce effectiveness. Always scarify when the lawn is dry.
Do Stihl scarifiers come with a battery and charger?
Most models are sold as tool only. The RLA 240.0 Set is an exception and includes a battery and charger.
What is the difference between scarifying and dethatching?
Scarifying cuts deeper into the soil to remove thatch and moss, while dethatching is a lighter process that removes surface debris. Stihl scarifiers can do both depending on the depth setting.
How often should I scarify my lawn?
Once a year in spring or autumn is sufficient for most lawns. Over-scarifying can damage the grass.
Are Stihl scarifiers easy to maintain?
Yes. Clean the blades after each use and check for wear. Battery models require little maintenance beyond keeping the battery charged.
Can I use a Stihl scarifier on artificial grass?
No. Scarifiers are designed for natural grass only. Using one on artificial turf will damage the blades and the surface.
What is the warranty on Stihl scarifiers?
Stihl offers a standard 2-year warranty on domestic use. Commercial use may have a shorter warranty period.
Which Stihl scarifier is best for a small garden?
The Stihl RL 540 corded model is a good budget choice for small gardens. The RLA 240.0 is also suitable if you prefer battery power.
Do I need a separate aerator if I have a scarifier?
Scarifying and aerating serve different purposes. A scarifier removes thatch, while an aerator improves soil drainage. Both are beneficial for lawn health.
Can I scarify a new lawn?
Wait at least one year after laying turf or seeding before scarifying. New lawns need time to establish strong roots.
Our verdict
The Stihl RLA 240.0 is the best overall scarifier for 2026, offering a great balance of power, ease of use, and battery convenience for most UK lawns. For a budget-friendly corded option, the Stihl RL 540 is a reliable choice for smaller gardens. Both models deliver the build quality and performance expected from the Stihl brand.
