If you want to save time, the battery-powered BGA 57 blower is the tool for you.

Lightweight and well-balanced, this battery leaf blower is easy-to-use, and with an extendable blower tube, it can be adjusted to suit you perfectly. The powerful blowing force means you can easily clear away debris, such as leaves, twigs and dirt, from your property.

The BGA 57 is part of the AK System of tools, which includes a grass trimmer, hedge trimmer, chain saws and lawn mowers, all using interchangeable batteries that can be swapped between tools in the range.

Quiet technology

The STIHL AK System tools are so quiet you don't even need to wear ear protection.



Extendable blower tubeExtendable blower tube 

The length of the blower tube can be easily adjusted to suit your height, so you have control over the direction of the blowing force.

Suitable for right or left-handed use 

Suitable for right or left-handed use

All of the controls and the safety locking lever are within easy reach on the handle, which makes it easy for you to use whether you are right or left-handed.

Neutral locking position    

There are two positions for the battery - in the first neutral position, the battery is secured in the machine but not connected to the contacts. This means you can carry the battery around easily without accidentally starting the blower. In the second position, the battery is fully pushed in and you can easily start the tool.

AK 20 battery         

AK 20 Battery

36 V lithium-ion battery for the AK System with an impressive 118 Wh capacity. The battery runtime differs depending on which tool it is fitted to, see individual models for more information. With charge level indicator (LED). Use in conjunction with the AL 101 battery charger.

AL 101 chargerAL 101 Charger

Charger for the STIHL AK System. With operating mode indicator (LED) and cable tie with Velcro tape. The charger can be wall mounted if required.


Question: How long does the battery last?

A: The recommended AK 20 battery will last up to 22 minutes or enough time to clear an area up to 760 m², depending on what you are clearing.

Question: How long does it take to charge?

A: To fully charge an AK 20 battery using the AL 101 charger, it takes 180 minutes, but you can charge it up to 80% in 135 minutes.

Question: What size of property will it maintain?

A: Great for cleaning medium to large city properties. 

Question: What battery does it use?

A: The blower is powered by an interchangeable 36 V lithium-ion battery.

Question: Are the batteries interchangeable?

A: Yes, all of the tools in the AK System use the same style of battery. There are three different batteries in the range, offering different capacities. For the BGA 57, we recommend the AK 20 battery and it is designed to be perfectly balanced with this battery. You can also use the higher capacity AK 30 battery in this tool. We don't recommend using the AK 10, as the BGA 57 won't run for as long with this smaller battery.


Question: What should I wear when using this blower?

A: We recommend that you wear snug-fitting clothes, eye protection, gloves and sturdy boots or shoes, and tie back long hair.


#1 Cleaning your BGA 57

When you have finished using the blower, remove the battery and clean using a damp cloth or soft brush.

#2 Storing your BGA 57

Store your BGA 57 in a clean and dry area and keep out of the reach of children at all times. You can hang it on a hook using the eyelet in the handle.

#3 Using your BGA 57

It takes more power to blow away damp leaves than dry leaves, so it will take you longer to clear a smaller area of wet leaves. If you can, wait until a dry day to clear your garden to make the most of your battery.

#4 Clearing leaves with your BGA 57

Instead of just blowing the leaves around the garden, blow them into a corner to keep them contained and make it easier to collect them.

#5 Looking after your battery

Don't use a damp or wet battery in your BGA 57 and avoid using them in extreme temperatures (very hot or very cold).
