Standard features

• 
  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-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.

• 
  Highlift blade

  The highlift blade gives a precise finish to the lawn and ensures optimal filling of the grass catcher box. The blade creates a strong air current in the housing, which makes the grass stand upright before cutting and efficiently carries the clippings into the catcher box using an integrated and powerful air flow system.

• 
  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.

• 
  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.

• 
  Carrying handles

  This STIHL lawn mower is equipped with carrying handles to make transport simple and loading easy. The carrying handles are also suitable as lashing points for securing the lawn mower with a strap during transport.

• 
  QuickFix quick-clamping devices

  The QuickFix clamping devices can be used to effortlessly fasten or release the handlebar of the STIHL lawn mower. This enables the lawn mower to be folded away compactly or made ready for action without using tools.

• 
  Polymer housing

  The extremely lightweight polymer housing combines high resistance and robustness against forces, heat and UV radiation.

• 
  Height-adjustable handlebar

  The handlebar can be set to several positions to suit your body height. This individual height adjustment ensures greater comfort without affecting the stability or manoeuvrability of the STIHL lawn mower.

• 
  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.

Additional features

• 
  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.
