BGA 57 Cordless Blower
AK System leaf blower
Overview
STIHL’s new lightweight cordless blower in the AK System is the successor to the BGA 56.
Ideal for domestic users, the BGA 57 is perfect for clearing jobs around the garden. Featuring a new design in line with other new STIHL releases, the blower also has an improved balance and better blowing performance –all whilst retaining a low weight (2.2 kg) and sufficient working time for domestic use (22 min with AK 20 battery).
The BGA 57 can be used without the need for ear protection. An adjustable blower tube allows you the choice of 3 lengths to suit the users height. The operators control handle is easy to use, with the trigger lockout designed symmetrically for right or left handed use.

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.
