Stihl RMA 2.39
Best OverallPros
- Excellent cut quality with Stihl's twin-blade system
- Central height adjustment with 7 positions
- Folding handles for compact storage
Cons
- Not self-propelled
- Grass catcher could be larger
The Stihl RMA 2.39 is the benchmark for mid-range electric mowers. It uses a 41 cm cutting deck and a twin-blade system that provides a clean, mulched finish. Owners consistently report that it handles damp grass better than many competitors, with less clogging. The central height adjustment lever is easy to reach and offers seven positions from 25 mm to 75 mm.
Battery life is a strong point, with the included AK 30 battery providing enough runtime for most medium-sized lawns (up to 400 m²). The mower is relatively light at 23 kg, making it easy to maneuver. The main drawback is the lack of self-propulsion, which can be tiring on larger or sloped lawns. The grass box at 40 liters is adequate but will require emptying on longer grass.
Stihl RMA 4.39
Best for Large LawnsPros
- Self-propelled with variable speed
- Wider 46 cm cutting deck
- Large 50-liter grass box
Cons
- Heavier than non-propelled models
- Battery runtime shorter on high speed
The RMA 4.39 is the logical upgrade for anyone with a lawn over 500 m². The self-propulsion system is smooth and adjustable, allowing you to match the walking speed to your pace. The 46 cm cutting deck reduces mowing time, and the 50-liter grass box means fewer trips to the compost heap. Owners praise its ability to handle thick, wet grass without stalling.
The mower runs on the same AK 30 battery as the RMA 2.39, but the extra power draw of the self-propulsion system means runtime is slightly lower, around 35 minutes. A second battery is recommended for larger lawns. Build quality is typical Stihl: robust plastic deck with metal handles and a solid feel. The height adjustment is central and offers six positions.
Stihl RMA 2.35
Best for Small LawnsPros
- Very lightweight and easy to maneuver
- Compact design for small storage spaces
- Good value for money
Cons
- Smaller 30-liter grass box
- Not ideal for thick, tall grass
The RMA 2.35 is Stihl's entry-level electric mower, designed for small urban lawns and gardens. At just 18 kg, it is one of the lightest mowers in its class, making it easy to push and lift. The 36 cm cutting width is narrow enough to navigate tight spaces and flower beds. Owners appreciate its nimble handling and the fact that it folds flat for hanging on a wall.
The included AK 20 battery provides about 30 minutes of runtime, which is sufficient for lawns up to 200 m². The cutting height is adjustable in six positions via a central lever. While it lacks the power of larger models, it handles regular weekly cuts without issue. The plastic deck is durable, and the overall build quality is solid for the price point.
Stihl RMA 5.39
Premium PowerPros
- Powerful motor for tough grass conditions
- High-quality build with metal components
- Excellent mulching performance
Cons
- Expensive compared to competitors
- Heavy and less maneuverable
The RMA 5.39 is Stihl's top-of-the-line electric mower, designed for users who demand maximum power and durability. It features a robust motor that can handle the thickest, wettest grass without bogging down. The 46 cm cutting deck is paired with a premium twin-blade system that delivers exceptional mulching and collection results. Owners report that the cut quality is on par with high-end petrol mowers.
This model is self-propelled with a variable speed control, and the drive system is smooth and responsive. The build quality is outstanding, with a reinforced plastic deck and metal handles. The main downsides are the weight (30 kg) and the price, which is significantly higher than other Stihl models. It is best suited for large, demanding lawns where performance is the priority.
Stihl RMA 2.37
Budget PickPros
- Lowest price in the Stihl range
- Lightweight and easy to store
- Good for small, flat lawns
Cons
- Smaller 35-liter grass box
- Shorter battery runtime
The RMA 2.37 is the most affordable way to get into the Stihl battery ecosystem. It shares the same basic design as the RMA 2.35 but with a slightly smaller 37 cm cutting width and a less powerful AK 20 battery. It is ideal for very small lawns (up to 150 m²) where budget is the main concern. Owners note that it is simple to use and maintain.
The build quality is typical Stihl: durable and reliable, even at the entry level. The cutting height is adjustable in six positions, and the handles fold for compact storage. The main trade-offs are the smaller grass box and shorter runtime, but for the price, it offers excellent value. It is not suitable for large or overgrown lawns.
Who Are Stihl Electric Lawn Mowers For?
Stihl electric mowers are designed for homeowners who value reliability, build quality, and the convenience of battery power. They are particularly well-suited for those who already own other Stihl battery tools, as the AK system is shared across their range of trimmers, blowers, and chainsaws. The mowers are ideal for small to medium-sized lawns, with the self-propelled models capable of handling larger areas.
Stihl's focus on robust construction means these mowers are built to last, often outlasting cheaper alternatives. They are a good fit for users who want a premium product without the maintenance of a petrol engine. However, they are not the cheapest option, and the battery ecosystem is less extensive than competitors like Makita or DeWalt.
Performance and Cut Quality
Stihl electric mowers are known for their excellent cut quality, thanks to the twin-blade system used in most models. This design creates a vacuum effect that lifts the grass before cutting, resulting in a cleaner, more even finish. Owners consistently report that Stihl mowers handle damp grass better than many rivals, with less clogging in the deck or grass box.
The motors are quiet and powerful, providing consistent torque even in thick grass. The self-propelled models offer smooth, variable-speed drive that makes mowing large areas less tiring. The mulching performance is also strong, with the blades chopping clippings finely enough to be left on the lawn without creating clumps.
Build Quality and Reliability
Stihl has a strong reputation for build quality, and their electric mowers are no exception. The decks are made from high-impact plastic that is resistant to cracking and corrosion. The handles are typically metal, and the height adjustment mechanisms are robust. Owners often report that Stihl mowers last for many years with minimal issues.
The AK battery system is well-regarded for its reliability and longevity. Stihl offers a two-year warranty on batteries and a longer warranty on the mower itself. The batteries are also compatible with a wide range of other Stihl tools, making them a good investment for those building a cordless outdoor power tool collection.
Alternatives to Stihl Electric Mowers
While Stihl is a strong contender, there are other brands worth considering. Makita offers a similar range of battery mowers with a more extensive 18V LXT ecosystem. DeWalt also has competitive models with high power output. For budget-conscious buyers, Flymo and Bosch offer good value options with adequate performance for smaller lawns.
If you prefer a petrol mower, Stihl also makes excellent petrol models. However, for most homeowners, the convenience and lower maintenance of an electric mower make it the better choice. The key is to match the mower to the size of your lawn and your budget.
What to Check Before Buying a Stihl Electric Mower
Before purchasing, consider the size of your lawn. The RMA 2.35 or 2.37 is sufficient for lawns under 200 m², while the RMA 2.39 is ideal for up to 400 m². For larger lawns, the self-propelled RMA 4.39 or 5.39 is recommended. Check the battery runtime and consider buying a second battery if your lawn is large.
Also consider the storage space. All Stihl mowers have folding handles, but the deck size varies. Ensure you have enough room to store the mower. Finally, check the cutting height range and make sure it suits your grass type. Stihl mowers typically offer a range from 25 mm to 75 mm, which covers most needs.
Mistakes to Avoid
A common mistake is buying a mower that is too small for the lawn, leading to longer mowing times and more frequent battery changes. Another is neglecting to charge the battery fully before the first use, which can affect long-term battery life. Finally, avoid using the mower on very wet grass, as this can cause clumping and strain the motor.
