Features

Standard equipment

  • Carrying handles Zoom
    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.

  • Quick Fix quick clamping devices Zoom
    Quick Fix quick clamping devices

    The Quick Fix quick clamping devices can be used to fasten or release the handlebar of the STIHL battery-powered lawn mower in a few seconds. This enables the lawn mower to be folded away compactly or made ready for action without using tools.

  • Foldable grass catcher box Zoom
    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 Zoom
    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 Zoom
    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.

  • Polymer housing Zoom

  • Easy-running wheels Zoom
    Easy-running wheels

    Eco mode

    When eco mode is activated, the speed of the lawn mower motor is automatically adapted to the actually required power. As a result, the STIHL battery-powered lawn mower consumes very little energy and can cover a larger area before it needs to be recharged.

Retrofitted equipment

  • Mulching function Zoom
    Mulching function

    This cordless lawn mower features an effective mulching function. Simply remove the grass catcher box and insert the mulching key. The clippings are finely shredded and evenly distributed over the lawn immediately after being mulched. Consistent mulch mowing reduces lawn thatch. The mulching function dispenses with the disposal of clippings and provides the lawn with moisture and important nutrients.
