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.
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
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.
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.

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.

The handlebar can be set to several positions to suit your body height. This individual height adjustment ensures comfortable and ergonomic lawn mowing, without in any way affecting the stability or manoeuvrability of the STIHL lawn mower.
