Description
STIHL HSA 50 Cordless Hedge Trimmer: 50cm AK System Hedge Cutter
The STIHL HSA 50 is a lightweight 36V cordless hedge trimmer designed for trimming bushes, shrubs and medium-sized hedges around the home. It weighs 2.9kg without a battery, has a 50cm double-sided cutting blade and can handle annual growth and branches up to approximately 18mm.
The HSA 50 is a strong choice for homeowners who want more cutting ability than a compact entry-level hedge trimmer without moving to a heavier professional machine. Its quiet battery-powered motor, balanced handles and cable-free operation make it particularly convenient for regular hedge maintenance in residential gardens.
It is part of the STIHL AK System, allowing compatible AK batteries to be shared with other STIHL cordless garden tools.
Choose the tool-only version if you already own a compatible STIHL AK battery and charger. Choose the kit option if you need the HSA 50 with an AK 10 battery and AL 101 charger.

Manufacturer figures are measured under standardised test conditions. Actual runtime, sound, vibration and cutting performance can vary according to the battery, hedge density, blade condition and working technique.
STIHL HSA 50 Battery Runtime
The HSA 50 can use compatible batteries from the STIHL AK System. The recommended AK 10 keeps the hedge trimmer well balanced and provides sufficient runtime for many domestic hedge-cutting jobs.
| Battery | Maximum working time | Best suited to |
|---|---|---|
| STIHL AK 10 | Up to 50 minutes | Regular domestic hedge maintenance and lighter handling |
| STIHL AK 20 | Up to 100 minutes | Larger gardens or customers sharing the battery with other AK tools |
| STIHL AK 30 / AK 30 S | Up to 130 minutes | Extended working time, with additional battery weight |
These are maximum working times. Dense growth, frequent stopping and starting, cold conditions and blunt or dirty blades can reduce actual runtime.
How the STIHL HSA 50 Performs in the Garden
Clean Cutting for Regular Hedge Maintenance
The HSA 50 uses double-sided, laser-cut and diamond-ground blades. The teardrop-shaped teeth help guide and retain twigs as the blades move, supporting a clean and controlled cut on regularly maintained hedges.
Lightweight and Easy to Control
At 2.9kg without a battery, the HSA 50 is light enough for routine domestic work while providing more capability than STIHL’s smallest hedge trimmers. The loop handle and rear control handle make it easier to guide the machine across the top and sides of a hedge.
Quiet Cordless Operation
Battery operation removes the need for petrol, pull starting, fuel storage and trailing electrical cables. Its relatively quiet operation also makes it well suited to gardens in residential and noise-sensitive areas.
Tip Protection Near Walls and the Ground
A screw-on tip protector helps reduce blade wear when working near paths, walls and ground-level growth. It also helps the blade move more smoothly past solid surfaces.
Simple Storage and Transport
The supplied blade scabbard covers the cutting teeth when the machine is not being used. An integrated hanging eyelet allows the hedge trimmer to be stored securely without taking up unnecessary floor or shelf space.
Who Is the STIHL HSA 50 Best For?
The HSA 50 is particularly well suited to:
- Homeowners with small or medium-sized hedges
- Regular trimming of privet, laurel and similar garden hedging
- Shaping shrubs and bushes
- Customers replacing a corded hedge trimmer
- Customers who already own STIHL AK System tools
- People who want a lighter alternative to a petrol hedge trimmer
The HSA 50 is not intended to replace a chainsaw or pruning saw for thick, woody branches. It is also not the best option for continuous professional hedge cutting or severely overgrown boundary hedges.
STIHL HSA 40 vs HSA 50 vs HSA 60
| Model | Battery system | Best for | Main reason to choose it |
|---|---|---|---|
| STIHL HSA 40 | AS System | Small hedges, soft annual growth and lightweight trimming | Compact and particularly easy to handle |
| STIHL HSA 50 | AK System | Small to medium-sized domestic hedges and growth up to approximately 18mm | Good balance of weight, runtime and cutting capability |
| STIHL HSA 60 | AK System | Larger hedges and more demanding domestic cutting | Longer blade, stronger gearbox and rotating rear handle |
Choose the HSA 40 for very light work and maximum portability. Choose the HSA 50 for general domestic hedge maintenance. Move up to the HSA 60 if you regularly maintain larger hedges or need greater cutting performance.

Frequently Asked Questions
Does the STIHL HSA 50 include a battery and charger?
That depends on the selected variation. The machine-only option does not include a battery or charger. The kit option includes an AK 10 battery and AL 101 charger.
Which battery is recommended for the STIHL HSA 50?
STIHL recommends the AK 10. It provides up to 50 minutes of working time and helps keep the hedge trimmer balanced and easy to handle.
Can I use an AK 20 or AK 30 battery?
Yes. Compatible STIHL AK System batteries can be used. The AK 20 and AK 30-series batteries provide longer maximum working times but add more weight than the AK 10.
How thick can the STIHL HSA 50 cut?
It is designed for annual growth and branches up to approximately 18mm. Thick, old or woody branches should be removed with a suitable pruning saw, lopper or chainsaw.
Is the STIHL HSA 50 suitable for large hedges?
It can maintain small and medium-sized hedges effectively. For longer, denser or more demanding hedges, the STIHL HSA 60 may be more appropriate because it has a longer blade and stronger cutting system.
How heavy is the STIHL HSA 50?
The machine weighs 2.9kg without a battery. Its working weight depends on which STIHL AK battery is fitted.
Can the STIHL HSA 50 be used in the rain?
No. The hedge trimmer and charger should be protected from rain and dampness. Store the machine, battery and charger in a clean, dry location.
