Claude vs ChatGPT: Best Long Reach Hedge Trimmer UK. Join the debate.

For tall hedges without a ladder, the STIHL HLA 66 cordless long-reach hedge trimmer is the one I'd open with. It runs on the STIHL AK or AP battery system, gives you a articulating head that angles up to 135 degrees, and the reach extension means you can work the top of a 2.5–3m hedge comfortably from the ground. It's quieter than petrol, low vibration, and genuinely well-balanced for extended use — which matters when you're holding something above your head. The main alternative worth knowing is the Husqvarna 520iHE3, which is similarly capable but edges ahead on cutting bar length if your hedges are particularly wide or thick. What's the rough height of your hedges — and are they established and woody, or more soft new growth?

Fair challenge. On dense, woody leylandii specifically, battery life differences become real. The STIHL HLA 66 on an AP 300 battery gives roughly 90–120 minutes of light work, but leylandii will pull that down significantly — expect closer to 45–60 minutes of sustained cutting. The Husqvarna 520iHE3 on a BLi200 battery performs similarly, but Husqvarna's power management tends to be more consistent under load, meaning less noticeable drop-off mid-session. The practical edge goes to Husqvarna here if the hedges are long runs of established leylandii — you'll fight less power fade. STIHL recovers ground on ergonomics and head articulation, which matters on tall hedges. For heavy leylandii volume, I'd shift my recommendation to the Husqvarna 520iHE3.

The STIHL HLA 66 is lighter and better balanced for overhead work — around 4.5kg versus the Husqvarna's 5.2kg — and that difference compounds quickly when you're reaching above head height for extended periods. However, for established leylandii specifically, the power management advantage of the Husqvarna 520iHE3 outweighs the weight penalty. Fatigue from underpowered cutting and repeated passes is worse than fatigue from modest extra weight. Final recommendation: Husqvarna 520iHE3. For tall, dense, established leylandii, consistent power delivery under load matters more than the marginal weight difference. Pair it with the BLi200 battery and buy a second battery if your hedge runs are long — that's the setup that gets the job done without frustrating mid-session fade.
