Carrying handles
The STIHL battery-powered lawn mower has two carrying handles integrated into the housing for ease of transport. They make the cordless mower easier to load or return to the upright position. The carrying handles are also suitable as lashing points, for example for securing the lawn mower with a strap during transport.

Foldable grass catcher box
The innovative grass catcher box is made of plastic and features a folding mechanism that makes it particularly easy to open and empty. The current of air produced during mowing blows the clippings into the grass catcher box and ensures its optimum filling. Special vanes in the box channel the air towards the ground, and so protect the user and lawn mower alike from dust and dirt that has been 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.
-
Flow-optimised blades
The flow-optimised blade trims the grass with minimal resistance, only swirling the air as much as absolutely necessary. As a result it consumes minimal battery capacity, which means that the stored energy is sufficient for the largest possible area.

STIHL Smart Connector
STIHL connected is a smart fleet management system that enables professional users to digitally manage machine fleets and work assignments.
This is managed by the STIHL Smart Connector - a sensor with a diameter of just under 5cm, which is mounted on the tool. It can be mounted on petrol, electric or battery-powered tools where it records and saves the operating hours while the motor is running and transmits this information via Bluetooth® 4.2 to the STIHL connected App (the smart connector can be mounted on non-STIHL tools too). The Smart Connector offers entirely new functions and services, as a basis for device management both in your home garden using the STIHL connected App, and for managing your machine fleet using the STIHL connected Portal.
Here’s a few reasons why STIHL connected can help manage your fleet of tools:
- The Digital Fleet Management keeps a record of all tools and their service record
- You get prompts when a tool needs servicing, so you never forget to change the plug, filter or just carry out maintenance
- You can see how many hours a tool has done, so you can plan which tools to use, replace or buy more of
- At the end of the day, you can open the app and see which tools are next to you - so you can tell if something is missing
- Book a service with your nearest STIHL Approved Dealer and give them access to see what work will be needed in advance.
STIHL Connected is an intuitive way to manage your machine fleet and workload intelligently and efficiently. Visit: STIHL connected FAQs to find out more.
