Husqvarna 122LKH Hedge Trimmer Attachment — 21in Double-Sided Blade, 180° Rotating Head

The Husqvarna 122LKH is a gas-powered hedge trimmer attachment that delivers a 21-inch double-sided cutter, 180° rotating head, and easy-start engine for precise hedge and shrub shaping.

The 122LKH turns Husqvarna's multi-tool powerhead into a focused hedge-trimming solution for homeowners and DIY landscapers who need extended reach, cleaner cuts, and the flexibility of add-on tools. Designed as an attachment for Husqvarna's power units, this hedge cutter balances blade length, rotation options, and user-focused starting features so routine yard shaping and seasonal cleanup feel faster and more controlled.

How does the 21-inch blade improve cutting performance?

The long cutter bar increases reach so you can trim larger sections of hedge with fewer passes, reducing time and effort. Laser-cut and double reciprocating blades ensure a consistent, clean shearing action that helps maintain neat lines on hedges and shaped shrubs.

• 21-inch laser-cut blades for extended reach and straight cuts
• Double-sided, double reciprocating design for efficient shearing
• Reduced need for repeated strokes, speeding up jobs

Can I adjust the head for awkward angles and overhead work?

Yes—the 122LKH offers 180° rotation that lets you angle the cutter head for sides, tops, and overhead branches without changing your stance. The rotation mechanism is designed for one-handed adjustment so you can reorient the blade quickly while keeping a secure grip on the tool.

• 180-degree rotating head for side or top trimming
• Simple one-hand adjustment to maintain control while repositioning
• Better ergonomics when working on tall or irregular hedges

What makes this attachment easy to start and use in the yard?

Husqvarna built the 122LKH to pair with a Smart Start-equipped powerhead and includes an air purge feature to minimize pull resistance when starting the engine. Those design choices reduce the effort required at startup and get you cutting sooner, especially useful when moving between tasks or making multiple starts during a session.

• Smart Start-compatible engine setup for low-effort starting
• Air purge reduces starter resistance and shortens choke cycles
• Detachable shaft for quick attachment and storage

Is this hedge trimmer attachment versatile for other yard jobs?

The 122LKH is part of Husqvarna’s attachment ecosystem, so a single powerhead can accept multiple click-on tools like pole saws and edgers (sold separately). That makes it a cost-effective choice if you want one engine to cover pruning, edging, and cutting tasks across the season.

• Attachment-capable design to work with other Husqvarna tools
• Detachable shaft for swapping tools without extra engines
• Two-year residential warranty for homeowner peace of mind

Who is this for: The Husqvarna 122LKH hedge trimmer attachment is aimed at homeowners, hobby landscapers, and weekend gardeners who already own or plan to buy a Husqvarna multi-tool powerhead and want an efficient, long-reach option for shaping hedges, pruning overhead shrubs, and finishing seasonal cleanup. It’s especially useful for people seeking cleaner cuts, easier angle control, and the convenience of a multi-purpose tool system rather than separate gasoline engines for each task.
