Who is the Stihl RLA 240 for?
The Stihl RLA 240 is a cordless electric scarifier designed for homeowners with small to medium-sized lawns (up to 500 square meters). It is ideal for those who want to avoid the noise, fumes, and maintenance of a petrol engine. The machine runs on Stihl's AK battery system, meaning if you already own other Stihl garden tools (trimmers, blowers, chainsaws) using the same batteries, you can share power packs across the range.
Performance and key specs
The RLA 240 uses a 36-volt motor powered by two AK series batteries (20 Ah or 30 Ah recommended). It offers a 30 cm working width, which is standard for a domestic scarifier. The machine comes with two interchangeable drums: a scarifier drum with spring steel tines for cutting through thatch, and a raking drum for collecting moss and debris. Depth adjustment is tool-free, with six settings from -12 mm to +12 mm.
Owner reviews consistently highlight the RLA 240's ability to lift moss and dead grass effectively without tearing up healthy turf. The motor provides enough torque to handle light to moderate thatch, though very thick, neglected lawns may require two passes. The collection basket has a 30-liter capacity, which is adequate for most jobs, though it fills quickly on mossy lawns.
Build quality and design
Stihl is known for robust build quality, and the RLA 240 is no exception. The chassis is made from reinforced plastic, keeping weight down to 14.5 kg without batteries. The handles are ergonomic and fold for storage. The wheels are large enough to roll over uneven ground without snagging. The battery compartment is well-sealed against dust and debris. Stihl offers a 2-year warranty on the machine, with an additional 1-year warranty on the battery when registered.
Alternatives to consider
If your lawn is larger than 500 square meters, consider the petrol-powered Stihl RL 540. It offers a 38 cm working width and a powerful 31 cc engine, but it is heavier and louder. For a budget-friendly cordless option, the Flymo Contour 1200 XT is lighter and cheaper, but it lacks the robust build and dual-drum system of the Stihl. The Bosch AVR 1100 is another popular corded electric scarifier, offering similar performance at a lower price point, but with the limitation of a power cable.
FAQs
What is the difference between scarifying and raking?
Scarifying uses spring tines to cut vertically into the lawn, removing thatch and moss. Raking uses a drum with flexible tines to lift debris to the surface without cutting the soil.
Can I use the Stihl RLA 240 on a wet lawn?
It is best to scarify when the lawn is slightly damp but not waterlogged. Wet grass clumps and clogs the collection basket, and the tines may tear the turf.
How long does the battery last on the RLA 240?
With two 30 Ah batteries, you can expect around 30 minutes of continuous use, which covers approximately 300-400 square meters depending on thatch thickness.
Does the Stihl RLA 240 come with a battery and charger?
No, the RLA 240 is sold as a bare tool. You need to purchase AK system batteries and a charger separately, unless you already own them.
How often should I scarify my lawn?
Most lawns benefit from scarifying once a year in early autumn or spring. Heavy clay soils or lawns prone to moss may need twice a year.
Is the Stihl RLA 240 easy to store?
Yes, the handles fold down, reducing the overall height to around 70 cm, making it easy to store in a shed or garage.
Can I use the RLA 240 on a sloping lawn?
Yes, the machine is stable on gentle slopes, but very steep banks are not recommended due to the risk of the machine tipping.
What is the noise level of the Stihl RLA 240?
It operates at around 85 dB, which is significantly quieter than petrol models. This makes it suitable for use in noise-sensitive areas.
Does Stihl make a petrol scarifier?
Yes, the Stihl RL 540 is a petrol-powered scarifier with a 31 cc engine and a 38 cm working width, ideal for large lawns.
What is the warranty on the Stihl RLA 240?
Stihl offers a 2-year warranty on the machine and an additional 1-year warranty on the battery when registered within 30 days of purchase.
Our verdict
The Stihl RLA 240 is the best overall battery scarifier for most homeowners, offering quiet, effective performance and excellent build quality. For larger lawns or those without battery access, the Stihl RL 540 petrol model remains the top choice for raw power.
