Description
Is the STIHL FSA 140 the right cordless brushcutter for you?
The STIHL FSA 140 Cordless Brushcutter is a high-output professional machine developed for landscapers, grounds-maintenance teams, estates, local authorities and demanding private users. It is designed to clear large areas of long grass, dense weeds and tougher vegetation without the fuel, exhaust emissions and starting procedure associated with a petrol brushcutter.
Its combination of 1.0 kW mechanical power, an ergonomic bike handle and the supplied GrassCut 260-2 metal blade makes the FSA 140 particularly effective when making controlled, sweeping cuts across paddocks, verges, orchards, banks and other areas of open ground.
Important: this is the bike-handle STIHL FSA 140. It is supplied as a tool-only machine, so a compatible STIHL AP battery and charger must be purchased separately.
STIHL FSA 140 key features
- Professional 1.0 kW output: delivers the power needed for demanding grass and vegetation-clearance work.
- Ergonomic bike handle: supports a natural side-to-side cutting action when working across larger areas.
- GrassCut 260-2 blade included: a reversible steel cutting blade designed for cutting tough grass and weeds.
- Three selectable power levels: match the machine’s performance and energy consumption to the job.
- Variable-speed trigger: gives the operator precise control over cutting speed.
- Constant Power: maintains strong cutting performance as the battery discharges.
- Power Boost: allows the motor to provide maximum available performance when required.
- Automatic cutting-tool recognition: helps the machine adjust its operating characteristics to the fitted cutting attachment.
- EC brushless motor: efficient, durable and low maintenance.
- Metal mesh air filter: supports effective motor cooling and reliable operation in demanding conditions.
- IPX4 protection: designed and tested for professional outdoor work in wet weather conditions.
- Smart Connector compatible: enables machine-use information to be recorded through STIHL connected systems when a compatible connector is fitted.
Why Masseys recommends the STIHL FSA 140
At Masseys, we recommend the FSA 140 to customers who need more cutting capacity than a general-purpose cordless strimmer but still want the convenience, reduced noise and low maintenance of battery power.
The FSA 140 occupies a particularly useful position in STIHL’s professional cordless range. It has enough power for regular work in long grass and heavier vegetation, while its bike handle and double shoulder harness make it better suited to sustained work across open areas than a conventional loop-handle strimmer.
We particularly recommend it for:
- Professional landscapers and grounds-maintenance contractors
- Schools, parks, estates and commercial premises
- Clearing long grass around trees, fences and field boundaries
- Maintaining paddocks, orchards, verges and banks
- Users replacing a professional petrol brushcutter
- Existing owners of compatible STIHL AP System batteries

Professional cordless performance without petrol
The FSA 140 has a rated voltage of 36 V and produces up to 1.0 kW of mechanical output. This gives professional users the performance required for more intensive vegetation clearance while retaining the principal advantages of a cordless machine.
There is no fuel to mix, no pull cord and no exhaust emission at the point of use. Starting is immediate, and the lower operating noise makes the FSA 140 particularly useful around schools, hospitals, hotels, housing developments and other noise-sensitive locations.
The electronic motor management system also provides consistent performance throughout the battery charge rather than allowing cutting speed to fall away noticeably as the battery discharges.
Bike handle for clearing larger areas
The FSA 140 uses an adjustable two-handed bike handle. This configuration allows the machine to be guided in a broad, controlled sweeping motion and distributes the workload more evenly between the operator’s arms and shoulders.
Compared with a loop-handle brushcutter, the bike-handle design is generally the better choice for:
- Large areas of open grass
- Long periods of continuous cutting
- Wide sweeping passes
- Using a metal grass-cutting blade
- Maintaining a consistent cutting height
The supplied double shoulder harness supports the machine during use, while the tool-free adjustable harness eye helps different operators obtain a comfortable working position.
GrassCut 260-2 metal blade included
The STIHL FSA 140 is supplied with a GrassCut 260-2 reversible steel blade. It is intended for cutting tough grass, dense weeds and similar vegetation where standard mowing line may wear too quickly or provide insufficient cutting performance.
The machine can also be used with other approved STIHL cutting attachments, including compatible mowing heads, provided the correct guard and installation components are fitted. Always follow STIHL’s operating instructions when changing the cutting tool.

Three power levels and variable-speed control
The control handle allows the operator to select one of three power levels. Lower settings can be used when working around obstacles or carrying out lighter trimming, helping to reduce energy consumption. The highest setting provides maximum performance for dense or resistant vegetation.
The variable-speed trigger then lets the operator regulate the cutting speed within the selected level. This combination gives considerably more control than a basic on/off cordless brushcutter.
Which battery should you use with the STIHL FSA 140?
The FSA 140 is part of STIHL’s professional AP System cordless range. It is supplied without a battery or charger so that existing AP System users do not have to purchase components they already own.
For most professional users, Masseys recommends the STIHL AP 300 S battery as a strong balance between operating time, battery weight and purchase cost.
For longer working periods and fewer battery changes, consider the higher-capacity STIHL AP 500 S battery. Actual working time will vary according to the cutting attachment, selected power level, vegetation density, temperature and operator technique.
You will also require a compatible STIHL AP battery charger. A faster charger can be particularly worthwhile for professional users operating several batteries throughout the working day.

STIHL FSA 140 versus FSA 140 R
The principal difference is the handle configuration:
- STIHL FSA 140: bike handle for wide sweeping cuts and prolonged work across larger, open areas.
- STIHL FSA 140 R: loop handle for working in confined spaces, around obstacles and on narrower paths or banks.
Choose the FSA 140 when productivity across open ground is the priority. Choose the FSA 140 R when manoeuvrability around trees, street furniture, fences and other obstacles is more important.
Frequently asked questions
Does the STIHL FSA 140 include a battery and charger?
No. The FSA 140 is supplied as a tool-only machine. A compatible STIHL AP System battery and charger must be purchased separately.

Yes. It is a professional brushcutter designed for landscaping, grounds maintenance, estate management and other demanding vegetation-clearance work.
Can the FSA 140 cut brambles?
The supplied GrassCut blade is primarily intended for tough grass and weeds. Light young bramble growth may be manageable, but established woody brambles may require a different approved cutting attachment. Ask Masseys for advice before fitting a different blade.
Can a mowing-line head be fitted?
Yes, the FSA 140 can be used with compatible STIHL mowing heads. The cutting attachment must be approved for the machine and used with the appropriate guard and fitting components.
Which battery does Masseys recommend?
For a balance of battery weight, working time and cost, Masseys generally recommends the STIHL AP 300 S. For longer professional working periods and fewer battery changes, consider the AP 500 S.
Can the STIHL FSA 140 be used in the rain?
The machine has an IPX4 protection rating and is designed for professional outdoor use in wet weather. It is not waterproof and must always be operated, cleaned and stored in accordance with STIHL’s instructions.
Is the FSA 140 quieter than a petrol brushcutter?
Yes. Its battery-powered EC motor produces less operating noise than a comparable petrol machine and creates no exhaust emissions at the point of use. Hearing protection should still be worn where required.
