Description
Professional cordless cutting power with precise loop-handle control
The STIHL FSA 140 R Cordless Brushcutter is a high-powered professional battery brushcutter designed for demanding mowing, grass clearance and grounds-maintenance work. It delivers 1.0 kW of mechanical cutting power while avoiding petrol, pull-starting and exhaust emissions during use.
Part of the professional STIHL AP System, also presented by STIHL within its ALLPRO battery platform, the FSA 140 R is designed for landscapers, contractors, councils, schools, estates and grounds teams that require dependable cordless performance throughout the working week.
The “R” version uses a loop handle rather than a bike handle. This provides greater freedom of movement when cutting around trees, posts, benches, fencing and other obstacles, as well as when working on banks, slopes and uneven ground.
The machine is supplied with an AutoCut C 26-2 nylon-line mowing head and a double shoulder harness. This is a tool-only product, so a compatible STIHL AP battery and charger must be purchased separately unless you already own them.

Why Masseys recommends the STIHL FSA 140 R
At Masseys, we recommend the FSA 140 R as the middle ground in STIHL’s professional loop-handle cordless brushcutter range. It provides a useful step up in cutting output from the FSA 120 R without moving all the way to the heavier-duty, higher-output FSA 200 R.
Its combination of 1.0 kW output, a wide mowing circle and a manoeuvrable loop handle makes it particularly suitable for professional users whose work includes both open grass and more complicated areas containing trees, fencing, signs, benches or other obstacles.
We especially recommend it for:
- Professional gardeners and landscape-maintenance contractors
- Schools, hospitals and housing developments where noise must be controlled
- Estates, parks, commercial grounds and substantial private properties
- Cutting long grass, weeds and overgrown areas
- Working around trees, posts, fencing and street furniture
- Maintaining banks, slopes and uneven ground
- Existing STIHL AP System users who already own suitable batteries
- Businesses seeking to reduce petrol storage, fuel handling and routine engine maintenance
For ordinary lawn edging and occasional domestic trimming, the FSA 140 R will normally provide more performance than is necessary. A lighter model from our STIHL strimmer and brushcutter range may be easier to handle and more economical.
Key features of the STIHL FSA 140 R
1.0 kW professional cutting performance
The brushless EC motor produces 1.0 kW of mechanical comparative power, giving the FSA 140 R the output required for regular professional mowing and clearance work.
Power is available immediately when the trigger is pressed, without starting a petrol engine, mixing two-stroke fuel or waiting for an engine to warm up.
Three speed levels and energy-saving mode
The updated control handle allows the operator to select from three power levels according to the vegetation and working conditions.
Lower settings can be used for lighter grass and more precise trimming, helping to conserve battery energy. The highest setting provides additional output for dense grass, weeds and more resistant growth.
An additional energy-saving mode is available when extending the remaining battery working time is more important than maximum cutting output.
Automatic cutting-tool recognition
The FSA 140 R can recognise the type of approved cutting attachment fitted and automatically adjust its operating speed to provide suitable performance for that attachment.
This helps the machine balance cutting output, battery consumption and control across different applications.
Quick-adjust loop handle
The loop handle can be repositioned quickly without tools, allowing the machine to be adjusted to the operator’s height and preferred working position.
Compared with a bike-handle machine, the loop-handle configuration provides greater manoeuvrability in confined areas and around obstacles. It is also particularly useful on banks, slopes and uneven terrain.
420 mm mowing circle
With an appropriate nylon-line mowing head fitted, the FSA 140 R offers a maximum mowing circle of approximately 420 mm. The wide cutting area allows professional users to cover grass and rough vegetation efficiently.
AutoCut C 26-2 mowing head included
The supplied STIHL AutoCut C 26-2 uses nylon mowing line for cutting grass, weeds and general vegetation. The mowing line can be advanced by tapping the head lightly on the ground while it is rotating.
The machine is also compatible with a selection of approved STIHL cutting attachments, including appropriate GrassCut, TrimCut, DuroCut, PolyCut, BrushCut and WoodCut options.
Important: the correct guard, barrier bar, harness and personal protective equipment must be used for the chosen cutting attachment. Always follow the STIHL instruction manual or ask the Masseys team before changing cutting systems.
Metal-mesh air filter
A fine metal-mesh air filter helps prevent debris from entering the motor’s cooling system. Maintaining effective airflow supports consistent performance and a long service life during frequent professional use.
The filter is accessible and designed to be cleaned as part of routine machine maintenance.
Constant cordless performance
STIHL’s electronic power management is designed to maintain consistent cutting performance as the battery discharges, rather than allowing tool output to reduce progressively with the remaining battery charge.
IPX4 weather protection
The FSA 140 R has an IPX4 protection rating, providing protection against splashing water from different directions. This makes it suitable for professional work in typical changeable British weather.
The battery, charger, machine and accessories should still be operated, transported and stored in accordance with STIHL’s instructions.
Suitable for noise-sensitive locations
Battery operation produces less noise than a comparable petrol-powered brushcutter and creates no exhaust emissions while the machine is being used.
This makes the FSA 140 R particularly useful around:
- Schools and colleges
- Hospitals and care facilities
- Housing developments
- Hotels and visitor attractions
- Offices and commercial premises
- Residential gardens and estates
STIHL Connected compatibility
The FSA 140 R is prepared for use with a compatible STIHL Smart Connector. Professional users can use the STIHL Connected system to record operating hours and support machinery-fleet and maintenance management.
Which battery does the STIHL FSA 140 R use?
The FSA 140 R uses batteries from the professional STIHL AP System. STIHL recommends the STIHL AP 300 S battery as the main battery pairing for this machine.
Depending on the selected power level, cutting attachment, vegetation and working technique, the AP 300 S provides an approximate maximum working time of between 22 and 45 minutes.
| Battery | Suitability | Masseys recommendation |
|---|---|---|
| STIHL AP 200 S | Compatible for shorter or lighter jobs | Useful where reduced battery weight is important, but expect shorter working periods. |
| STIHL AP 300 S | Manufacturer-recommended battery | The best general balance of runtime, weight and professional performance. |
| STIHL AP 500 S | Higher-capacity professional battery | Consider for demanding schedules or when the battery will also power other high-output AP tools. |

Actual working time will vary according to:
- Selected power setting
- Cutting attachment and mowing-line diameter
- Grass and vegetation density
- Operator technique
- Ambient temperature
- Battery age and condition
- Frequency of starting and stopping
STIHL FSA 120 R, FSA 140 R or FSA 200 R?
| Model | Power | Best suited to | Recommended battery |
|---|---|---|---|
| STIHL FSA 120 R | Approximately 0.8 kW | Routine professional grass maintenance, lighter overgrowth and users prioritising runtime | AP 300 S |
| STIHL FSA 140 R | 1.0 kW | Regular professional mowing, tougher grass, mixed terrain and work around obstacles | AP 300 S |
| STIHL FSA 200 R | Approximately 1.6 kW | Dense growth, intensive clearance and users who genuinely require maximum cutting output | AP 500 S |
Choose the FSA 120 R when most of the work is routine grass maintenance and battery efficiency is the priority. Choose the FSA 140 R when you need a clear increase in cutting capacity while retaining good manoeuvrability. Move to the FSA 200 R when dense growth and intensive clearance work justify its additional output.

Frequently asked questions
Is the STIHL FSA 140 R supplied with a battery and charger?
No. The FSA 140 R is supplied as a tool-only machine. A compatible STIHL AP battery and charger must be purchased separately unless you already own them.
Which battery is recommended for the FSA 140 R?
STIHL recommends the AP 300 S battery. It offers a strong balance of professional performance, runtime and manageable battery weight.
How long does the AP 300 S last in the FSA 140 R?
Approximate maximum working time is between 22 and 45 minutes, depending on the selected power level and operating conditions. Dense vegetation, heavier cutting attachments and continuous full-power use will reduce runtime.

The “R” identifies the loop-handle version. The loop handle provides greater manoeuvrability around trees, posts, fencing and other obstacles and is useful when working on banks or uneven ground.
What is the difference between the FSA 140 and FSA 140 R?
Both machines use the same professional cordless power platform. The FSA 140 R has a loop handle and is supplied with an AutoCut mowing head, making it particularly suitable for precise trimming and working around obstacles. The standard FSA 140 uses a bike-handle configuration that is better suited to broad sweeping movements across open ground.

Yes. It is designed for professional landscaping, estate maintenance, local-authority work and commercial grounds care. Its brushless motor, metal-mesh air filter, adjustable power settings and IPX4 protection are intended for regular professional operation.
Can the FSA 140 R use a metal blade?
Yes, the machine can use selected approved STIHL cutting attachments. The correct guard, barrier bar, harness and personal protective equipment must be fitted for the chosen blade. Check the instruction manual or speak to Masseys before changing attachments.
Is the FSA 140 R suitable for an ordinary domestic garden?
It can be a good choice for large gardens, estates, paddocks and substantial areas containing long grass or rough vegetation. For normal lawn edging and occasional garden trimming, a lighter and less expensive STIHL model will usually be more appropriate.
Is the FSA 140 R a replacement for the FSA 135 R?
Yes. STIHL positions the FSA 140 R as the updated successor to the FSA 135 R, with a revised motor unit, improved power-to-weight balance, updated controls and new handle design.
Can the FSA 140 R be used in wet weather?
The machine is IPX4 rated and protected against splashing water from different directions. It is designed for professional use in typical changeable weather, but it must always be used, transported and stored according to STIHL’s instructions.
