1. STIHL GTA 26: The Versatile All-Rounder
The GTA 26 is the tool that started the revolution. It remains our top recommendation for gardeners who need a lightweight, precise tool for shrubs, small branches, and timber DIY projects.

• Compact Design: Small enough to fit in a holster, making it perfect for one-handed tidying.
• Simple Maintenance: Features a tool-free chain replacement and requires manual oiling using a small bottle of Multioil Bio.
• Best For: Light pruning, breaking down garden waste, and hobbyist woodworking.

2. STIHL GTA 30: The Powerhouse for Large Gardens
The newly released GTA 30 fills the gap between hobby tools and professional gear. It adopts the 6-inch bar of the larger models but keeps the simplicity of the AS System.

• Dual Battery Power: Uses two AS 2 batteries to provide significantly more torque and runtime than the GTA 26.
• Innovative Tensioning: Includes a spring-loaded "RightTight" system—just flip the handle and the chain tensions itself automatically.
• Best For: Landowners with larger properties who need to tackle thicker branches (up to 15 cm) without the weight of a full-sized chainsaw.

3. STIHL GTA 40: The Professional’s Choice
Designed for arborists and foresters, the GTA 40 is a "pro" tool in every sense. It is built for all-day use and can even be used as a secondary saw when climbing.

• Automatic Oiling: Unlike the 26 and 30, the GTA 40 has an internal oil reservoir that automatically lubricates the chain while you work.
• Arborist Ready: Features a lanyard attachment point for secure climbing and a robust IPX4 weather-resistance rating for work in the rain.
• Variable Speed: The trigger allows for precise speed control, giving the user "rip" power when needed and finesse for delicate cuts.

Which one should you buy?

• Choose the GTA 26 if you want the lightest tool for quick, occasional garden tidying.
• Choose the GTA 30 if you have a lot of trees to manage and want the best balance of power and value.
• Choose the GTA 40 if you are a professional user who requires automatic oiling and a saw that can withstand daily, heavy-duty use.
