Stihl RMA 460
Best OverallPros
- Powerful 36V system handles thick grass
- Variable speed self-propulsion
- Central cutting height adjustment
Cons
- Heavier than push models
- Batteries sold separately
The Stihl RMA 460 is the sweet spot in the brand's cordless lineup. It uses two AK 30 batteries in series for a 36V system that delivers consistent torque even in damp grass. Owners report cutting times of 45-60 minutes on a single charge with the included batteries, covering lawns up to 1/4 acre.
The self-propelled drive is smooth and variable speed, making it easy to match your walking pace. The steel deck is durable, and the 19-inch cutting width is a good balance between maneuverability and efficiency. Central height adjustment with seven positions from 1 to 3.5 inches gives flexibility for different grass types.
Stihl RMA 510
Best for Large LawnsPros
- Widest cutting deck in Stihl's range
- Excellent mulching capability
- Durable steel construction
Cons
- Heavy and less maneuverable
- Premium price point
The RMA 510 is Stihl's largest cordless mower with a 21-inch steel deck. It is designed for lawns over 1/4 acre and comes with the same 36V twin-battery system as the RMA 460 but with a wider cut. Owner reviews highlight its excellent mulching performance and the ability to handle tall, thick grass without bogging down.
At 55 pounds, it is the heaviest model in this roundup, but the self-propelled drive makes it manageable on flat terrain. The five-position cutting height adjustment ranges from 1 to 3.5 inches. The grass bag holds 13 gallons, reducing trips to the compost pile.
Stihl RMA 235
Best Budget / Small LawnsPros
- Lightweight and easy to carry
- Affordable entry to Stihl ecosystem
- Quiet operation
Cons
- Narrow cutting width
- Plastic deck less durable than steel
The RMA 235 is a compact push mower ideal for small urban lawns and tight spaces. It runs on a single 18V AK 10 battery, making it the lightest Stihl cordless mower at just 28 pounds. Owners appreciate how easy it is to maneuver around flower beds and garden obstacles.
Cutting height adjusts centrally with three positions from 1.5 to 3 inches. The 7-gallon grass bag is adequate for small lawns. Runtime with the standard AK 10 battery is around 20-25 minutes, which is enough for most small gardens. It is also very quiet compared to gas mowers.
Stihl RMA 443
Best Value Self-PropelledPros
- Self-propelled at a lower price
- Good balance of power and weight
- Steel deck for durability
Cons
- Smaller battery capacity than RMA 460
- Not as powerful in very thick grass
The RMA 443 bridges the gap between the budget RMA 235 and the premium RMA 460. It features a 17-inch steel deck and a single-speed self-propelled drive. It uses two AK 20 batteries for a 36V system, offering a good balance of power and runtime for medium-sized lawns up to 1/5 acre.
Owner reviews note that it is noticeably lighter than the RMA 460 at 42 pounds, making it easier to push manually when the battery runs low. The cutting height has six positions from 1 to 3.5 inches. The grass bag holds 11 gallons.
Stihl RMA 339
Best for Medium LawnsPros
- Lightweight and easy to maneuver
- 36V power in a compact package
- Folds for compact storage
Cons
- Plastic deck less durable
- Smaller grass bag (8 gallons)
The RMA 339 is a push mower that uses two AK 10 batteries in series for a 36V system. It is lighter than the steel-deck models at 38 pounds and features a folding handle for compact storage. It is best suited for medium lawns with relatively flat terrain.
Cutting height adjusts centrally with six positions. Owners report good cut quality on regular grass but note that it struggles slightly in very thick or wet conditions compared to the steel-deck models. The 8-gallon grass bag requires more frequent emptying.
What to Check Before Buying a Stihl Cordless Mower
Stihl's cordless mowers all use the AK battery system, but there are important differences. First, check the voltage: entry-level models like the RMA 235 use a single 18V battery, while most others use two batteries in series for 36V. The 36V models offer significantly more power for thick grass.
Second, consider the deck material. Steel decks are more durable and better for rough terrain, but they add weight. Plastic decks are lighter and rust-proof but may not last as long. Third, look at the self-propulsion feature. The RMA 460 and RMA 510 have variable speed, while the RMA 443 has a single speed. Push models like the RMA 235 and RMA 339 are lighter but require more effort on slopes.
Mistakes to Avoid
A common mistake is buying a mower with too small a battery for the lawn size. The RMA 235 with a single AK 10 battery is only suitable for very small lawns under 1/8 acre. For larger lawns, choose a 36V model with larger AK 30 batteries for longer runtime.
Another mistake is ignoring the weight. The RMA 510 at 55 pounds is heavy to push manually if the battery runs out. If you have a hilly lawn, consider a lighter model like the RMA 339 or ensure the self-propelled drive is adequate for slopes. Also, check that the grass bag size matches your lawn; smaller bags require more frequent stops.
