Powerful Cordless Performance for Demanding Gardens
The STIHL FSA 80 is a high-performance, battery-powered brushcutter engineered to tackle the toughest mowing, cutting, and clearing jobs in a domestic garden. Its powerful and efficient brushless EC motor delivers consistent power, ensuring a clean cut even as the battery discharges. Thanks to its battery power, the FSA 80 has low noise emissions, making it an excellent choice for working in built-up or noise-sensitive environments without disturbing neighbours.
Please note: This is the tool-only version of the FSA 80. The battery and charger are required for operation and are sold separately.
Intelligent Control and Ergonomic Design
The FSA 80 puts the operator in complete control with a variable speed trigger that features two distinct power levels. Level 1 (ECO mode) conserves energy for lighter tasks like trimming lawn edges, extending the battery runtime. Level 2 unleashes the tool’s full power for mowing thick grass and dense vegetation. The machine is fitted with a new style loop handle with a quick-mounting system, allowing for easy adjustment to the user’s height for a comfortable and ergonomic working position. This handle design makes it easier to manoeuvre on slopes, around trees, and across uneven terrain. For added comfort during longer jobs, the FSA 80 comes with a basic harness and features an eyelet for easy attachment.
Versatile and Smart Operation
Supplied as standard with the AutoCut 27-2 mowing head, the FSA 80 is also compatible with a wide array of other STIHL cutting attachments, including the TrimCut, DuroCut, PolyCut, and GrassCut cutting tools. A clever feature is its automatic tool recognition, which adjusts the motor speed to the optimal level for whichever cutting attachment is fitted, maximising performance and efficiency. Furthermore, the tool is compatible with the Smart Connector, allowing it to be integrated into the STIHL connected system for tracking operating hours and managing maintenance schedules via a smartphone app.

Frequently Asked Questions
Frequently Asked Questions
What battery and charger do I need for the STIHL FSA 80?
The FSA 80 is part of the STIHL AK battery system. It is compatible with the AK 10, AK 20, and AK 30 S batteries. For the best balance of performance and runtime, STIHL recommends the AK 30 S battery. You will also need a compatible charger, such as the AL 101 or AL 301. Battery and charger are sold separately.
Is the STIHL FSA 80 powerful enough for thick grass and weeds?
Yes, the FSA 80 is designed for demanding mowing jobs in home gardens. Its powerful brushless EC motor and two-speed control allow you to use full power for cutting through thick grass, weeds, and overgrown areas. It can also be fitted with a metal grass cutting blade for tougher conditions.
What cutting attachments can be used with the FSA 80?
The FSA 80 is highly versatile. It comes standard with the AutoCut 27-2 line mowing head but is also compatible with other STIHL cutting tools, including the TrimCut, DuroCut, PolyCut, and various GrassCut metal blades, allowing you to adapt the tool to different tasks.
How does the ECO mode on the FSA 80 work?
The ECO mode is the lower of the two power settings. By selecting this mode on the control handle, you reduce the motor’s speed and power consumption. This is ideal for lighter tasks like trimming lawn edges and helps to significantly extend the battery’s working time on a single charge.
