Target audience and application
The GTA 40 is tailored for horticulture, landscaping, and arboriculture professionals.
Its lightweight design (1.4 kg) and efficient EC motor make it ideal for:
- Tree and shrub maintenance
- Wood processing on construction sites
- Crown reduction tasks
- Aerial operations by trained arborists
Comparison with the STIHL GTA 26
While both the GTA 40 and GTA 26 are battery-powered pruners, the GTA 40 is engineered for professional use, offering enhanced features:
Power and Performance: The GTA 40 boasts a 0.41 kW output with a 21.6 V rated voltage, providing consistent power throughout its battery life.
Design and Ergonomics: The GTA 40’s 15 cm (6″) bar length and soft-grip control handle ensure comfortable and secure operation, even in wet conditions.
Battery System: This system utilizes two AS 2 batteries discharged in parallel, ensuring longer operational time. The tool requires both batteries to function.
Additional Features: Includes side-mounted chain tensioning for easy adjustments, automatic chain lubrication, and an attachment ring for fall protection during aerial tasks.
In contrast, the STIHL GTA 26 is more suited for light garden pruning and is geared towards domestic use. The GTA 40’s professional-grade features and performance make it a more robust option for demanding tasks.
User feedback
As the GTA 40 is a recent release, user reviews are limited. However, early discussions highlight its dual battery setup, with some users suggesting a preference for larger AS batteries to enhance efficiency.

The GTA40 does not have a top guard like the 26 has. The top guard is handy when pruning branches of small trees.
It does look good though and would complement a GTA26 which is probably what Stihl is aiming for. It will be interesting to find out how much they will cost when released?
It’s great to see Stihl supporting this battery powered line with cool products like this GTA and the pruner.

Looks ideal Josh for hedge reductions where you’re either working close or at arms length, bit less bulky than a top handle and way faster than a silky👍👌
