Stihl AK System - Cordless Tools for Medium-Sized and Larger Gardens
STIHL’s AK System offers versatile, battery-powered tools designed for medium-sized and larger gardens. Perfect for a wide range of tasks—from mowing lawns to cutting firewood—this system caters to homeowners seeking flexibility and efficiency in their gardening work.
The expanding AK System includes:
- Chainsaws: MSA 60 C-B, MSA 70 C-B
- KombiEngine: KMA 80 R
- Pole Pruner: HTA 50
- Leaf Blowers: BGA 57, BGA 60, SHA 56 (blower and vacuum)
- Grass Trimmers: FSA 57, FSA 60 R, FSA 80, FSA 80 R
- Hedge Trimmers: HSA 50, HSA 60, HLA 56 (long-reach)
- Lawn Care: 11 cordless lawn mowers and the RLA 240 scarifier
These tools are powered by interchangeable AK 10, AK 20, or AK 30 batteries. While all batteries fit each tool, higher-capacity models, such as the AK 30, are recommended for power-intensive tools like the MSA 70 C-B chainsaw.
Some AK System tools are available as sets, including a battery and charger, offering cost savings compared to separate purchases. Individual tools are also sold separately, ideal for users who already own compatible batteries and chargers.

Key
Recommended Battery
Reduced Tool Performance
¹ Power Capacity according to the specifications of the cell manufacturer
² The battery working times and area specifications for each battery charge are estimates and may vary depending on how the tool is used and what is being cut
³ With higher output power tools, the same work is completed more quickly, e.g. with the FSA 60 R compared to the FSA 57
⁴ Level 1 - Level 2
⁵ In Boost mode
⁶ When working in an area, only move the tool in one direction (no crossing-over)
