Description
STIHL FSA 80 Cordless Brushcutter
The STIHL FSA 80 is a powerful 36V cordless brushcutter designed for cutting tall grass, weeds and more demanding areas in medium to large domestic gardens. Its bike handle supports a comfortable, controlled sweeping action across open ground, while the quiet and low-maintenance cordless design removes the need for fuel, pull-starting or an electrical cable.
The FSA 80 is supplied with a GrassCut 230-2 metal blade and basic harness. Choose the tool-only version if you already own a compatible STIHL AK System battery and charger, or select the kit with an AK 30 S battery and AL 101 charger.

Why choose the STIHL FSA 80?
Powerful cordless cutting
The FSA 80 produces 0.8 kW of power and is designed for jobs that require more cutting ability than a lightweight cordless grass trimmer. It is well suited to tall grass, thicker weeds, rough garden edges and larger areas that need regular clearing.
Comfortable bike handle
The ergonomic bike handle helps the operator guide the cutting attachment in a broad, controlled arc. This makes the FSA 80 particularly effective when working across larger open sections of grass or vegetation.
The handle position can be adjusted without tools, helping different users find a comfortable working position. It can also be repositioned to make the machine easier to transport and store.
Two power levels
Choose between two operating levels according to the job:
- Level 1 helps conserve battery energy during lighter cutting
- Level 2 provides maximum performance for denser grass and tougher vegetation
This allows you to balance cutting power and battery runtime without changing machines.
Constant cutting performance
The electronically controlled EC motor works with STIHL Constant Power technology to maintain consistent performance as the battery discharges. This helps the machine continue cutting effectively rather than gradually losing power as the battery level falls.
Automatic cutting-tool recognition
The FSA 80 can recognise compatible cutting attachments and adjust performance accordingly. This helps achieve suitable operating characteristics when changing between approved metal blades and mowing heads.
Quiet and low maintenance
The cordless motor is quieter than a comparable petrol-powered machine and requires no fuel mixing, spark-plug maintenance or pull-starting. It is a practical choice for residential gardens and other areas where noise needs to be kept under control.
Where does the STIHL FSA 80 work best?
The FSA 80 is particularly suitable for:
- Cutting tall or overgrown grass
- Clearing weeds and heavier garden growth
- Maintaining rough boundaries
- Working across larger open areas
- Cutting around orchards and less formal garden areas
- Clearing banks and awkward sections of ground
- Regular domestic garden maintenance where extra cutting power is required
For light lawn edging and routine trimming around obstacles, a smaller loop-handle model may be easier to manoeuvre. For larger sweeping work and thicker vegetation, the FSA 80’s bike handle and metal blade make it the stronger choice.
STIHL FSA 80 battery runtime
Indicative operating times with a metal blade are:
- AK 10 battery: up to 20 minutes on power level 1 or 10 minutes on power level 2
- AK 20 battery: up to 50 minutes on power level 1 or 30 minutes on power level 2
- AK 30 S battery: up to 60 minutes on power level 1 or 40 minutes on power level 2
The AK 30 S is the recommended battery for the FSA 80.
Actual working time will vary according to grass density, cutting attachment, selected power level, operator technique and weather conditions.
STIHL FSA 80 or FSA 80 R?
The two machines share a similar cordless power platform but are designed for different working styles.
Choose the STIHL FSA 80 when:
- You regularly work across larger open areas
- You prefer a bike handle
- You need a controlled sweeping cutting action
- You expect to use a metal grass-cutting blade
- Tall grass and heavier vegetation are frequent jobs
Choose the STIHL FSA 80 R when:
- You work in tighter or more confined areas
- You regularly cut around trees, furniture or obstacles
- You prefer a loop handle
- Manoeuvrability is more important than a broad sweeping action
The FSA 80 is generally the better choice for open ground, while the FSA 80 R is designed to be easier to position in restricted spaces.
Compatible batteries and chargers
The STIHL FSA 80 is part of the 36V STIHL AK System.
It can be used with compatible AK System batteries, although runtime and machine balance vary according to the battery selected. The AK 30 S is recommended for achieving the most practical runtime during demanding brushcutting work.
Customers who already own compatible AK System equipment can purchase the tool-only version and use an existing battery and charger.
Compatible cutting attachments
The FSA 80 is supplied with a GrassCut 230-2 metal blade.
It can also accept selected compatible STIHL cutting attachments, including approved mowing heads, for different types of work. Always use the correct guard and fittings for the attachment being installed.
Speak to Masseys before changing cutting attachments if you are uncertain which mowing head, blade, guard or fitting is required.

Frequently asked questions
Does the STIHL FSA 80 come with a cutting head?
The FSA 80 is supplied with a GrassCut 230-2 metal blade rather than a nylon-line mowing head. Compatible STIHL mowing heads can be purchased separately for applications where nylon line is more suitable.
Does the STIHL FSA 80 include a battery and charger?
The tool-only version does not include a battery or charger. The kit option includes an AK 30 S battery and AL 101 charger.
Which battery is recommended for the STIHL FSA 80?
STIHL recommends the AK 30 S battery. It provides up to approximately 60 minutes of operation on power level 1 or 40 minutes on power level 2 when using a metal blade under test conditions.
Can I use my existing STIHL AK battery?
Yes. The FSA 80 is compatible with the STIHL AK System. However, a lower-capacity battery will provide a shorter working time, and the AK 30 S is the recommended option.
Is the STIHL FSA 80 suitable for tall grass?
Yes. The FSA 80 is specifically suited to tall grass, weeds and more demanding growth. Its bike handle and GrassCut metal blade make it effective for sweeping work across larger open areas.
What is the difference between the FSA 80 and FSA 80 R?
The FSA 80 has a bike handle and is supplied with a GrassCut metal blade, making it well suited to larger open areas. The FSA 80 R has a loop handle and is easier to manoeuvre around obstacles and in restricted spaces.
Can the cutting blade be replaced with a nylon-line head?
Yes, the FSA 80 can use selected compatible STIHL mowing heads. The correct guard, attachment and fittings must be used. Masseys can advise which components are required.
Is the STIHL FSA 80 a professional machine?
The FSA 80 belongs to STIHL’s AK System, which is principally intended for demanding domestic users. Customers requiring a machine for intensive daily professional use should also consider STIHL’s AP System brushcutters.
Does a cordless brushcutter need servicing?
Cordless brushcutters require less routine engine maintenance than petrol machines, but the cutting attachment, guard, fasteners, gearbox area, controls and battery connections should still be inspected regularly. Masseys provides servicing and repair support for STIHL garden machinery.
