The STIHL HLA 66 is a lightweight, cordless long-reach hedge trimmer designed for professionals who need precision and flexibility in hedge maintenance. Whether you're shaping tall hedges or trimming low shrubs, the adjustable cutter bar, ergonomic design, and quiet EC motor make it perfect for efficient work in residential zones, parks, and public spaces. As part of the STIHL AP System, it’s built for daily use, even in wet conditions.
Professional Power & Quiet Operation: The high-quality EC motor delivers fast blade acceleration for clean, precise cuts, while running quietly enough for use in noise-sensitive areas like neighbourhoods and hospitals.
Versatile Cutting Angles: The cutter bar adjusts from -45° to +70°, giving you flexibility to trim tops, sides, and ground-level plants. It also folds parallel to the shaft for easy transport and storage.
Ergonomic & Ambidextrous Design: The control handle is designed for both right- and left-handed users, with a self-resetting locking lever for added safety and ease of use.
Lightweight & Manoeuvrable: The loop handle allows for excellent mobility, even in tight or narrow spaces, ideal for professional landscaping work.
Splashproof & Weather-Ready: Certified to IPX4 standards, the HLA 66 is splashproof and tested for durability in adverse weather conditions, so you can work confidently rain or shine.
Part of the STIHL AP System: Compatible with other STIHL AP battery tools, making it easy to switch between tasks without changing power systems.

Q: How long will the Battery last?
A: The recommended AP 100 Battery will last up to 72 minutes, this does depend on what is being cut and how the tool is being used.
Q: How long does it take to charge?
A: To fully charge an AP 100 Battery it takes 100 minutes, or to charge it up to 80%, it takes 75 minutes with the AL 101 charger.
Q: Are the Batteries Interchangeable?
A: Yes, all of the tools in the PRO Cordless System use the same style of battery. There are 7 different batteries in the range, which all have different capacities. For the HLA 66, we recommend the smaller capacity AP 100 battery as it is lighter and means the tool is perfectly balanced, but you can use any of the other batteries in this range.
Q: Does the performance of the Battery reduce as it depletes?
A: No there is no gradual drop in performance – the battery runs at full power until it is fully depleted.
Q: Will the blades need sharpening?
A: Keeping the blades sharp will give a neat cut on whatever you are trimming. If you notice that the blades are getting jammed easily or the machine is struggling, the blades may need sharpening. Our STIHL SHOP retailers can do this for you.
Q: What should I wear when using this tool?
A: We recommend that you wear snug-fitting clothes, eye protection, gloves and sturdy boots or shoes, and tie back long hair.
