Battery Performance
As part of the versatile STIHL AK System, the RMA 239.1 C can be powered by various batteries to suit the size of your lawn. The expected coverage per full charge is as follows:
| Battery Model | Max. Area per Charge |

| AK 10 | up to 120 m² |
| AK 20 (Recommended) | up to 250 m² |

Key Features
Ergonomic and Convenient Design: The mower features a unique height-adjustable, mono-comfort handlebar. This single-sided design provides unobstructed access to the grass catcher box and can be folded down for compact storage and easy transport, aided by a practical integrated carry handle.
Efficient Grass Collection: The 40-litre grass collection box is designed for easy emptying. It features a fill-level indicator to signal when it’s full, and its clever design uses airflow to ensure dense filling, maximising its capacity. Vents on the side direct air downwards, protecting the user from swirling dust and debris.
Central Cut-Height Adjustment: A single, easy-to-use lever allows for simple adjustment of the cutting height across several levels, with a scale indicating the current setting. This allows you to adapt perfectly to the conditions of your lawn for optimum results.
