The STIHL FSA 120 cordless brushcutter is a powerful professional battery machine designed for cutting long grass, dense weeds and larger areas of rough ground. Its ergonomic bike handle provides a natural sweeping action, making it particularly effective for open spaces, verges, paddocks, orchards and grounds-maintenance work.
Part of the professional STIHL AP System, the FSA 120 combines strong cutting performance with low noise, simple push-button starting and zero exhaust emissions at the point of use. It is a practical alternative to a petrol brushcutter for landscapers, grounds teams and demanding domestic users.
Important: this is a tool-only machine. It is supplied with a GrassCut 230-2 metal blade and double shoulder harness. A compatible AP battery and charger are required and are available separately.

What is included with the FSA 120?
This Masseys listing is for the FA08 200 0000 GrassCut blade version and includes:
- STIHL FSA 120 cordless brushcutter.
- GrassCut 230-2 reversible metal cutting blade.
- Double shoulder harness.
- Appropriate guard and standard fitting equipment.
The battery and charger are not included. Customers who do not already own compatible AP System equipment will need to add an AP battery and a suitable charger.
For most users, we recommend the STIHL AP 300 S battery. For longer working periods, consider the higher-capacity STIHL AP 500 S battery. You can view compatible models in our STIHL battery charger range.
Who is the STIHL FSA 120 suitable for?
The FSA 120 is best suited to people who regularly need to clear more than ordinary lawn edges. Typical users include:
- Professional gardeners and landscape contractors.
- Grounds-maintenance teams and local authorities.
- Schools, hospitals and organisations working in noise-sensitive locations.
- Estate, paddock and orchard owners.
- Demanding domestic users maintaining large or overgrown areas.
- Existing AP System owners who want to move away from a petrol brushcutter.
The bike-handle configuration is particularly effective when working across broad, open areas. For detailed trimming around trees, posts, benches and other obstacles, the STIHL FSA 120 R with loop handle may be the more suitable choice.
Key features
Powerful 36 V AP System performance
The FSA 120 is part of STIHL’s professional battery platform and develops approximately 0.80 kW of mechanical power. Intelligent Constant Power electronics help maintain consistent cutting performance as the battery charge falls.
AP batteries can also be shared with a wide selection of professional STIHL chainsaws, hedge trimmers, blowers, pole pruners and KombiMotors. Browse the wider STIHL professional cordless range at Masseys.
Bike handle for larger areas
The ergonomic bike handle supports the broad, side-to-side movement normally used when clearing long grass and weeds. This makes it easier to cover open ground efficiently than with a conventional loop-handle strimmer.
A central, tool-free clamping mechanism allows the handle position to be adjusted to suit the operator. The handle can also be rotated for easier transport and more compact storage.
GrassCut 230-2 metal blade
The supplied GrassCut 230-2 is a 230 mm reversible steel blade designed for cutting tough grass and coarse weeds. It is a suitable choice for areas where ordinary nylon line would wear quickly or struggle to maintain cutting performance.
The FSA 120 can also accept compatible STIHL mowing heads, including selected AutoCut, TrimCut, DuroCut and PolyCut options. When fitted with a suitable mowing head, the machine can provide a cutting circle of up to approximately 380 mm.
Two power levels and variable-speed control
The control handle allows the operator to select between two power levels:
- Level 1/ECO: reduces maximum speed to extend battery working time during lighter cutting.
- Level 2: provides full performance for thicker grass and more demanding vegetation.
The variable trigger gives additional control when approaching trees, fences, planted areas or other sensitive obstacles.
Automatic cutting-tool recognition
The FSA 120 can recognise the type of compatible cutting attachment fitted and automatically adjust its operating speed. This helps the machine provide appropriate performance when switching between line heads, polymer blades and metal cutting tools.
Efficient brushless EC motor
The brushless EC motor is efficient, durable and requires less routine maintenance than a petrol engine. There is no pull cord, fuel mixture, spark plug or warm-up procedure: insert a charged battery, release the controls and begin work.
Low-noise cordless operation
Battery power substantially reduces operating noise compared with a conventional petrol brushcutter. This makes the machine particularly useful around homes, schools, care facilities, hospitals and other locations where noise disruption needs to be minimised.
IPX4 splash-water protection
The FSA 120 is IPX4 rated and designed for professional use in wet grass and changeable weather. IPX4 means splash-water protected; it does not mean that the machine or battery should be submerged or cleaned with a pressure washer.
STIHL Connected compatibility
The machine is compatible with a STIHL Smart Connector, allowing operating hours and maintenance information to be recorded through the STIHL Connected system. This can be particularly useful for professional users managing several machines.
Battery options and approximate working times
The FSA 120 works with compatible STIHL AP batteries. Actual runtime varies according to the battery, cutting attachment, selected power level, vegetation density, temperature and operating technique.
| Battery | With nylon mowing head | With metal blade |
|---|---|---|
| AP 300 S | Approximately 50–30 minutes | Approximately 110–60 minutes |
| AP 500 S | Approximately 60–35 minutes | Approximately 130–70 minutes |
The higher figure generally represents lighter work or a lower power setting, while tougher vegetation and full-power operation reduce runtime.
For most customers buying the FSA 120 for regular maintenance, the AP 300 S provides a good balance of weight, runtime and cost. The AP 500 S is more suitable when maximum handheld working time is the priority.

What Masseys thinks
Our view: the STIHL FSA 120 is an excellent choice for customers who need a proper bike-handle brushcutter but want the easier starting, lower noise and reduced maintenance of battery power.
It sits in a useful position within the AP range: considerably more capable than a light garden strimmer, but not as heavy or expensive as STIHL’s largest professional clearing saws. We particularly recommend it for regular long-grass cutting, paddock edges, orchards, verges and professional grounds maintenance.
For most users, we would pair it with an AP 300 S battery. Customers working for longer uninterrupted periods may prefer the AP 500 S. The main decision is handle type: choose this bike-handle FSA 120 for open areas and sweeping work, or the FSA 120 R when manoeuvrability around obstacles is more important.
