Stihl HL-KM – 145 degree Hedgetrimmer attachment 500mm

The STIHL HL-KM 145° Long-Reach Hedge Trimmer attachment is the definitive “KombiSystem” upgrade for landscapers who refuse to balance on shaky ladders. While standard attachments offer limited movement, this professional 500mm (20″) head features a redesigned lightweight gearbox and a massive 145° pivoting range, allowing you to square off hedge tops and prune vertical faces with a single, continuous sweep. By moving the center of gravity closer to the engine, STIHL has slashed the operating weight to just 2.3 kg, making it the most balanced long-reach tool in its class. Whether you’re sculpting formal boxwood or reclaiming overgrown hawthorn, the HL-KM 145° turns your KombiEngine into a surgical pruning machine that reaches further and cuts cleaner than anything else in your trailer.

• Incremental 145° Precision Locking: Unlike “friction-stay” heads that can slip, this unit uses a positive-locking mechanism that adjusts in precise increments. This ensures the blade stays exactly where you set it, even when pushing through heavy, woody branches.

• Redesigned Ultra-Slim Gearbox: The modern, low-profile gearbox isn’t just lighter; its tapered shape prevents the tool from snagging in dense foliage, allowing for a much smoother “pull-through” when finishing a hedge face.

• Synchronized Double-Sided Blades: The 500mm cutter bar features diamond-ground teeth on both sides, optimized for a high stroke rate. This allows for multi-directional cutting, effectively doubling your productivity compared to single-sided alternatives.

• Zero-Tool “Fold-Flat” Storage: The head folds parallel to the shaft in seconds, reducing the total length to a compact 148 cm. This makes it easy to store in a small van or a wall-mount rack without removing the attachment.

• Shaft Extension Compatibility: This is one of the few attachments engineered to maintain perfect balance when paired with the 1-metre carbon fibre or aluminum extensions, giving you a total reach of over 3.5 metres without the weight of a dedicated long-reach unit.
