The biggest advantages of the STIHL RMA 339 are that is lightweight, cordless and easy to handle. Its innovative STIHL 36V AK battery system runs off powerful lithium-ion cells. The batteries can be used for many other STIHL machines with this battery system by simply unplugging and replugging them. For especially economical mowing, collecting and retrofittable mulching, use the activatable eco mode. It automatically adapts the motor speed to the required power, for the greatest possible mowing time. The flow-optimised blade also increases the energy efficiency. This saves valuable battery capacity and increases the coverage. But that is not all: the lawn mower is also equipped with a foldable grass catcher box as well as central cutting height adjustment. This enables the compact machine to achieve the best results on small and medium-sized lawns, and its straightforward handling makes it popular with all gardeners.
Features
| Carrying handles | The STIHL battery-powered lawn mower has two carrying handles integrated into the housing for ease of transport. They make the cordless mower easier to load or return to the upright position. The carrying handles are also suitable as lashing points, for example for securing the lawn mower with a strap during transport. |

| Foldable grass catcher box | The innovative grass catcher box is made of plastic and features a folding mechanism that makes it particularly easy to open and empty. The current of air produced during mowing blows the clippings into the grass catcher box and ensures its optimum filling. Special vanes in the box channel the air towards the ground, and so protect the user and lawn mower alike from dust and dirt that has been thrown up. The level indicator signals the correct time for emptying. The airflow generated by the blade raises the level indicator. When the basket is full, the airflow stops. If the airflow is too low, the level indicator returns to its idle state and this is an indication to empty the catcher box. Optimal airflow is required in order for the level indicator to function fully. External influences such as wet, dense or tall grass, a low cutting height, contamination, etc. may affect the airflow and the performance of the level indicator. |

| Flow-optimised blades | The flow-optimised blade trims the grass with minimal resistance, only swirling the air as much as absolutely necessary. As a result it consumes minimal battery capacity, which means that the stored energy is sufficient for the largest possible area. |

| Central cutting height adjustment | The central cutting height adjustment on this STIHL battery-powered lawn mower is spring-loaded making it easy to operate, and has several adjustment levels to obtain the desired cutting height for the lawn. The current height is indicated by a scale. In this way, the grass can always be optimally adapted to the conditions of the lawn surface and the use. |
