Standard equipment

  • Easy start engine (ReadyStart) Zoom
    Easy start engine (ReadyStart)

    Thanks to the ReadyStart technology, the engine of the STIHL petrol lawn mower can be reliably started up with minimal effort both during cold and warm starting. 


  • Self-propulsion Zoom
    Self-propulsion

    Self-propulsion on the STIHL lawn mowers provides for the desired forward momentum during mowing. This makes working easier, especially on large lawns and inclines.

  • Highlift blade Zoom
    Highlift blade

    The highlift blade provides for an evenly cut lawn and ensures optimal filling of the grass catcher box. The blade generates a strong air current in the housing, which makes the grass stand upright before cutting and efficiently conveys the clippings into the catcher box using an integrated and powerful air flow system.

  • Fold-open grass catcher box with level indicator Zoom
    Fold-open grass catcher box with level indicator

    The plastic grass catcher box can be easily opened and emptied thanks to its folding mechanism. The current of air produced during mowing blows the clippings into the grass catcher box and ensures a high degree of filling. Thanks to the downward-facing vanes, the air is guided sideways towards the ground, preventing dirt from being 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.

  • Easy-running wheels Zoom
