What is the STIHL HSA 140 R designed for?
The STIHL HSA 140 R is a professional 36V cordless hedge trimmer designed for annual pruning, hedge reduction and cutting back thick, mature or heavily established growth. It is part of the STIHL AP System and is available with either a 60cm (24″) or 75cm (30″) double-sided cutting blade.
The “R” designation identifies the pruning version of the machine. Its 38mm tooth spacing and torque-focused cutting action make it better suited to heavier hedge maintenance than fine ornamental trimming.
Please note: this is a tool-only machine. A battery and charger are not included. STIHL recommends the AP 200 S battery for an effective balance of runtime, weight and handling. View our STIHL battery chargers if you also require a charger.
STIHL HSA 140 R key features
- Professional pruning performance: designed for mature hedges, annual reduction work and denser growth.
- Two cutting lengths: choose a 60cm blade for manoeuvrability or a 75cm blade for longer hedge runs.
- 38mm tooth spacing: allows heavier material to enter the cutters more readily than on the fine-trimming HSA 140 T.
- Three selectable speed settings: adjust the cutting action to suit the hedge, finish and working conditions.
- Double-sided cutting blade: supports efficient cutting in either direction.
- Rotating multifunction handle: helps maintain a comfortable hand and wrist position when cutting hedge sides or tops.
- Anti-vibration system: helps reduce transmitted vibration during prolonged professional use.
- Anti-blocking function: assists when the blade becomes obstructed by dense material.
- Battery slot in the machine: no external battery cable is required when using a compatible AP battery.
- IPX4 rated: protected against splashing water from any direction.
Which blade length should you choose?
| Blade option | Best suited to | Weight without battery |
|---|---|---|
| 60cm / 24″ | Confined spaces, shaped hedges, frequent direction changes and users prioritising manoeuvrability | 4.3kg |
| 75cm / 30″ | Long, straight hedge runs where extra reach and more cutting coverage per pass are useful | 4.6kg |
For most mixed professional work, the 60cm version is easier to manoeuvre. The 75cm model is particularly useful on long, broad hedges where its additional reach can reduce the number of passes required.

Battery compatibility and approximate working times
The HSA 140 R uses batteries from the professional STIHL AP System. STIHL recommends the AP 200 S because it provides a good balance between machine weight, handling and working time.
| Battery | Approximate working time | Recommendation |
|---|---|---|
| STIHL AP 200 S | 100–150 minutes | Recommended option for balance and everyday professional use |
| STIHL AP 300 S | 175–245 minutes | Longer working time with additional battery weight |
| STIHL AP 500 S | 210–290 minutes | Maximum working time from a slot-in AP battery |
Working times are approximate and vary with the selected speed, hedge density, cutting technique, temperature and battery condition. Lower speed settings generally provide longer working times.

STIHL HSA 140 R versus HSA 140 T
| Model | Main purpose | Tooth spacing | Best choice for |
|---|---|---|---|
| HSA 140 R | Pruning and hedge reduction | 38mm | Thick, mature and established hedge growth |
| HSA 140 T | Fast, precise trimming | 30mm | Fine-leaved, ornamental and regularly maintained hedges |
Choose the HSA 140 R when the priority is heavier cutting and annual reduction work. Choose the STIHL HSA 140 T when the priority is speed, precision and a particularly clean finish on finer growth.
For less demanding professional maintenance, the lighter and lower-priced STIHL HSA 100 cordless hedge trimmer may also be worth considering.
Who should buy the STIHL HSA 140 R?
The HSA 140 R is particularly well suited to:
- Professional gardeners and landscape contractors
- Estate and grounds-maintenance teams
- Owners of large gardens with mature hedging
- Users moving from a professional petrol hedge trimmer
- Existing STIHL AP System users who already own compatible batteries
- Customers who regularly carry out annual pruning or hedge reduction
For light, infrequent trimming of young domestic hedges, a smaller model from our cordless hedge trimmer range may be lighter and more economical.

Frequently asked questions
Does the STIHL HSA 140 R include a battery and charger?
No. The HSA 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 HSA 140 R?
STIHL recommends the AP 200 S. It provides an approximate working time of 100–150 minutes while retaining good machine balance. Larger AP batteries can provide longer working times but add weight.
Should I choose the 60cm or 75cm blade?
Choose the 60cm blade for better manoeuvrability, shaped hedges and confined areas. Choose the 75cm blade for additional reach and faster coverage on long, straight hedge runs.
What is the difference between the HSA 140 R and HSA 140 T?
The HSA 140 R is the pruning version, with 38mm tooth spacing and an emphasis on mature growth and hedge reduction. The HSA 140 T is the trimming version, with 30mm tooth spacing and a faster cutting action for fine, accurate finishing.
Can the HSA 140 R cut a 38mm branch?
The 38mm measurement describes the spacing between the blade teeth; it is not a guaranteed maximum branch diameter. Actual cutting capacity depends on the species, hardness and condition of the material. Very thick or woody branches should be removed using suitable loppers or a pruning saw rather than forcing them through the hedge-trimmer blade.
Can the HSA 140 R be used in wet weather?
The machine has an IPX4 rating, meaning it is protected against splashing water from any direction. This does not mean it is waterproof or suitable for immersion. Always follow the operating instructions for the machine and battery.
How long does the HSA 140 R run on one charge?
Approximate working time ranges from 100–150 minutes with an AP 200 S, 175–245 minutes with an AP 300 S and 210–290 minutes with an AP 500 S. Actual results depend on the selected speed, hedge density, temperature and working technique.
Is the HSA 140 R suitable for domestic users?
Yes, particularly for owners of large gardens and mature hedges. However, it is a professional-grade machine. Customers maintaining smaller or lighter hedges may find the HSA 100 or another model from the STIHL cordless range easier and more economical to use.
