Stihl HLA 66 Cordless Long-reach Hedge Trimmer – 50 cm / 20 inch

The STIHL HLA 66 is a lightweight, professional-grade cordless long-reach hedge trimmer designed for tackling tall and wide hedges, or ground cover plants. Building on the popular HLA 65, the HLA66 offers improved balance to reduce fatigue, an ergonomic handle with self-resetting Ergo lever for easy control, and a smart, streamlined design.

At 205 cm overall length and with a 50 cm (20″) double-sided, double-edged blade, the HLA-66 is ideal for trimming tall hedge sides and tops without ladders. The cutter head adjusts from -45° to +70°, so you can reach tricky angles or shape the tops precisely. When folded flat, it shortens to just 132 cm for easier transport and storage.

Whether you’re a gardener, groundskeeper, or landscaper, the STIHL HLA 66 makes hedge maintenance safer and faster, even in rain thanks to its IPX4 rating.

STIHL HLA 66 AP Battery Run Time

The HLA 66 is compatible with all AP batteries, including the AP 20. It can also be used with AR 2000 L and AR 3000 L backpack batteries for even longer run times: up to 715 minutes with the AR 2000 L and up to 1,040 minutes with the AR 3000 L.

The HLA 66 is compatible with all AP batteries, including the AP 20. It can also be used with AR backpack batteries for even longer run times: up to 715 minutes with the AR 2000 L and up to 1,040 minutes with the AR 3000 L.

Designed for Comfort and Control

Thanks to excellent balance and an optimally placed battery centre of gravity, the HLA66 reduces wrist and arm strain during long sessions. The loop handle allows you to manoeuvre confidently, even in tight spots or when shaping awkward hedges.

The intuitive Ergo lever system means you can operate the HLA 66 continuously without repeated restarts, and it suits both left- and right-handed users. Starting is simple: unlock, pull the trigger, and go.

Precision Cutting and Robust Build

The STIHL HLA-66 is equipped with double-sided blades for cleaner, sharper cuts on every pass. The included tip protector prevents accidental damage when working close to walls or the ground. A blade scabbard is supplied for safe storage and transport.

Its efficient EC motor delivers high performance while staying quiet and energy efficient. Combined with STIHL AP system batteries, the HLA 66 offers long working times and consistent power output until the battery is fully discharged.

Battery Options and Runtime

The HLA 66 is recommended with the AP 200 battery but works with all STIHL AP batteries. With an AP 300 S, you can expect up to 223 minutes of run time, and even longer if you use backpack batteries like the AR 2000 L or AR 3000 L.
