    Standard features

    • Easy start engine

      Thanks to the SmartChoke technology, the engine starts up reliably and with minimal effort both during cold and warm starting. 


    • Self-propelled

      Self-propelled STIHL lawn mowers take the effort out of lawn mowing. The drive mechanism propels the mower without it physically having to be pushed. This makes working easier, especially on large lawns and inclines.

    • Mulching function

      During mulching, the mulching blade shreds the mown grass before it falls back into the turf as a nutritional fertiliser. And with the appropriate mulching kit available as an optional accessory for this lawn mower, the machine can also be converted into a Multi-mower.

    • Multi-blade

      Thanks to the specially shaped cutting blades, the multi-blade of the STIHL petrol lawn mower shreds the mown grass. When using the grass catcher box, it is then efficiently conveyed in the box. During mulch mowing, the mown grass is directly ejected onto the lawn so that it falls back onto the turf as a nutritional fertiliser.

    • 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.

    • Smooth running wheels

      The smooth running wheels of the STIHL lawn mowers are extremely robust and hard-wearing. They have been equipped with a traction pattern and directional stability tread pattern for effortless manoeuvring and to help hold perfect line during mowing.

    • Super soft grip

      The super soft grip is comfortable to hold, especially when used over longer periods.

    • Aluminium housing

      STIHL lawn mowers fitted with aluminium decks are comparably low in weight, sturdy and durable. The powder-coated surfaces, retain their shine for a long time, unaffected by fuel and corrosion.

    • Central cutting height adjustment

      The central cutting height adjustment is spring-loaded, which makes it easy to set the desired cutting height in several settings. The current height is indicated by a scale.
