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

Lightweight and well-balanced, this cordless 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 that you can easily clear away debris, such as leaves, twigs and dirt, from your garden.

The BGA 57 replaces the BGA 56 as part of the AK System of tools, which includes a grass trimmer, hedge trimmer, chainsaws and lawn mowers and uses interchangeable batteries that can be swapped between tools in the range.

  • Run time with AK 20 battery: up to 22 min
  • Run time with AK 30 battery: up to 27 min


Quiet technology Quiet technology

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

Extendable blower tube Extendable 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 Neutral locking position

There are two positions for the battery - in the first neutral position, the battery is secured in the machine but is 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.

Soft grip Soft grip

The handle has a soft finish, so it's comfortable to hold, even when you're using it for longer, and provides a secure grip no matter what the weather.

Hanging eye Hanging eye

The BGA 57 can be easily hung up in the shed or garage, thanks to the eyelet in the handle

AL 101 charger AL 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.


QHow 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 760m², depending on what you are clearing.

QHow 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.

QWhat size garden will it maintain?

A: The BGA 57 leaf blower is great for clearing medium to large gardens.

QWhat battery does it use?

A: The blower is powered by an interchangeable 36V Lithium-Ion battery.

QAre 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, which all have different capacities. For the BGA 57, we recommend the AK 20 battery, and it is designed to be perfectly balanced with this battery, but 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.

QWhat should I wear when using this blower?

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


#1Cleaning your BGA 57

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

#2Storing 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.

#3Using 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.

#4Clearing 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 up.

#5Looking 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). To find out more about looking after your battery, read our blog post.
