Standard equipment

  • Mulching function Zoom
    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.

  • Kawasaki engine with OHV Zoom
    Kawasaki engine with OHV

    The powerful Kawasaki engine with large air filter is particularly high-torque, smooth-running and durable.


    FLEXIBLE MOWING AND MULCHING. The multi-blade allows you to mow and mulch without changing the blade. The specially shaped blades shred the cut grass. Then you decide whether the grass should be transported into the collection box via air flow, or further shredded and distributed evenly over the green area to become a nutrient-rich fertiliser.

  • 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.


    LOW-MAINTENANCE AND FLEXIBLE. The drive with hydrostatic transmission allows you to continuously adjust the speed of your lawn mower with a large adjustment range. The use of a hydrostatic oil for power transmission means that no mechanical components are required except for the throttle lever. The lever opens and closes a valve which regulates the pressure in the oil. The low number of components means significantly reduced maintenance requirements compared to conventional transmission forms.

  • Easy-running wheels Zoom
    Easy-running wheels

    The easy-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 perfect line holding during mowing.


    RUN THE ENGINE WITHOUT BLADES. The blade-brake coupling ensures effective crankshaft protection. You can use it to decouple the blade from the engine on your lawn mower. If, for example, you need to drive over rocky ground or stone slabs, you can use the wheel drive of the lawn mower to move the lawn mower without the blades running.

  • Super soft grip Zoom
    Super soft grip

    Particularly ergonomic and pleasant handling is ensured by the super-soft grip of the STIHL lawn mower.

  • Mono-comfort handlebar
    Mono-comfort handlebar

    The foldable mono-comfort handlebar provides for easy handling during mowing and removal of the grass catcher box. Moreover, the STIHL lawn mower can be stored and transported in a space-saving manner. The handlebar can be adapted to your body height without using tools and ensures ergonomic working.

  • Aluminium housing with skirting protectors. Zoom
    Aluminium housing with skirting protectors.

    The STIHL lawn mowers with aluminium housing are characterised by their high sturdiness and relatively low weight. The side skirting protectors ensure particularly high durability. Equally advantageous are the powder-coated housing surfaces, which retain their shine for a long time, unaffected by fuel and corrosion.

  • Central cutting height adjustment Zoom
    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.

    • STIHL Smart Connector Zoom
      STIHL Smart Connector

      The STIHL Smart Connector forms the basis for using all STIHL connected functions. These functions can be used via both the STIHL connected App and the STIHL connect Portal. Once correctly attached to a STIHL power tool or another manufacturer’s power tool, the STIHL Smart Connector records operational hours while the machine is running, stores them and transmits them to your smartphone via Bluetooth as soon as it is within range. The data received in the STIHL connected App is transferred to the STIHL Cloud when there is an internet connection. The data is stored there in compliance with data protection regulations. The STIHL connected App and STIHL connected Portal allow you to access your power tool data at any time. STIHL connected opens up new avenues for professional users to obtain a convenient and transparent overview of their own power tool fleet. At the same time, STIHL connected provides information including operational hours, power tool status including reminders of overdue maintenance, the last known location, and whether or not the power tools are currently nearby. For professional users, this means improved digital fleet management, more efficient processes within companies, and even closer contact with STIHL dealers. Private users can also use the system to keep an eye on their power tools and carry out maintenance at the right time.
