Quick verdict
A Husqvarna gas combi unit built around a detachable shaft and a 21-inch double-sided hedge trimmer head that pivots through 180 degrees. It suits a homeowner with tall or wide hedges who also wants to click on a pole saw or edger later. The caveat is that a shaft-mounted hedge head is heavier and slower to shape with than a handheld trimmer, so it is a reach tool first.
Strengths
- 21-inch laser-cut double-sided, double reciprocating blades
- 180-degree head adjusts with one hand

- Gas power with no cord or battery limit
Weaknesses
- Engine displacement and weight are not stated in the listing
- Two-stroke fuel mixing and more upkeep than battery
- Pole saw and edger attachments are sold separately
- Less nimble than a handheld for detailed shaping

Who this trimmer is for
A handheld hedge trimmer runs out of reach at about head height, and a step ladder on soft ground beside a hedge is nobody’s idea of safe. The Husqvarna 122LKH puts a 21-inch double-sided hedge head on the end of a gas combi shaft, with a pivoting joint so the bar can lie flat across the top of a tall hedge or tilt down the face. It is for the homeowner with tall privet, laurel or arborvitae, a long run of hedge, and ideally an interest in clicking on Husqvarna’s pole saw or edger attachments on the same powerhead later.

What you get
The listing covers the 122LKH powerhead and shaft with the hedge trimmer attachment fitted, under Husqvarna part number 970796101. The cutter bar is 21 inches with laser-cut, double-sided, double reciprocating blades, and the head rotates through 180 degrees with a one-handed adjuster. The shaft is detachable, so the lower half separates for transport and for swapping attachments. Starting is Husqvarna’s Smart Start system, which reduces pull resistance. Not stated in the listing: engine displacement, weight, fuel tank size or the length of the assembled unit. The sibling Husqvarna 122LKP pole saw on the same powerhead is listed at 21.7cc, so expect an engine of that class.
Cutting performance
Double-sided, double reciprocating blades mean both blades move in opposite directions and both edges cut, which lowers vibration and lets you sweep in either direction without flipping the tool. A 21-inch bar is a sensible length on a pole: long enough to flatten a hedge top in a few passes, short enough not to make the head unmanageable at full extension. Husqvarna does not state a branch capacity; shaft-mounted hedge heads in this class typically handle the finger-thick growth of a yearly trim and bog on anything much thicker, so cut oversize stems with loppers first. The 180-degree head is the feature that earns the tool its keep: level across the top, vertical down the sides, and angled under overhangs without climbing.
Engine and running costs
This is a small 2-cycle gas engine, which means premixed fuel, a spark plug and an air filter to look after, and more noise than a battery unit. In return there is no runtime limit and no battery platform to buy into, and a gas combi unit holds its power to the end of the tank. Smart Start is a genuine convenience on a tool that gets started and stopped often along a hedge. Owners of Husqvarna’s 122-series combi units describe them as reliable starters when stored with stabilized or drained fuel and as stubborn when left with stale mix over winter, which is true of every small two-stroke.
Build, handling and ergonomics
Husqvarna does not state a weight, and that is the number that matters most on a pole hedge trimmer, because the cutting head sits several feet from the grip. Expect the usual trade: a gas combi with a hedge head is heavier and more tiring at full reach than a handheld trimmer, and a harness or shoulder strap is worth adding if the kit does not include one. The one-handed head adjustment is well regarded because you can change angle without setting the tool down. The split shaft makes it fit in a car trunk.
Living with it
Mix fuel at the ratio in the manual, which for Husqvarna two-strokes is typically 50:1 with their own oil, and use ethanol-free fuel if you can get it. Clean and oil the blades after each session and have them sharpened when they start tearing rather than slicing. The attachment interface is the long-term value: a pole saw head and an edger are sold separately and click onto the same shaft, so one engine covers three jobs. Warranty terms are not quoted in the listing; check the product page and register the tool.
Alternatives to Consider
The Husqvarna 322HD60 is the handheld 24-inch gas trimmer for anyone whose hedges are reachable from the ground and who wants faster shaping. The Husqvarna 122LKP is the same powerhead with a pole saw head, the better first buy if tree limbs are the bigger problem. On the battery side, a 40V pole hedge trimmer kit from Greenworks or Ryobi is lighter, quieter and simpler to maintain for a short hedge run, at the cost of finite runtime.
Verdict
Buy the Husqvarna 122LKH if your hedges are too tall for a handheld, you prefer gas for unlimited runtime, and you can see yourself adding the pole saw or edger attachment. Skip it if everything you trim is reachable from the ground, or if you want a published weight and a quieter tool, where a handheld trimmer or a battery pole unit serves better.

Husqvarna 122LKH Gas Combi Trimmer with 21-Inch Hedge Trimmer Attachment FAQs
No. The hedge head is mounted on the combi shaft, so it is a reach tool for tall and wide hedges. For ground-level shaping, a handheld such as the Husqvarna 322HD60 is quicker and lighter.
Husqvarna lists a pole saw and an edger as click-on attachments for the detachable shaft, both sold separately. Check the product page for the full list for this shaft.
The listing does not state displacement. The sibling 122LKP pole saw on the same powerhead is listed at 21.7cc, so expect a small 2-cycle engine of that class, running on premixed fuel.
Husqvarna does not give a weight in the listing. Gas combi units with a hedge head are heavier than handheld trimmers and the head sits far from the user, so a shoulder strap is worth having.
