If you have been shopping Husqvarna’s lineup, you have probably run into a wall of part numbers, and the husqvarna string trimmer #967628201 is one that keeps surfacing. That number is the manufacturer SKU for the popular 129L straight-shaft gas trimmer, a homeowner-grade machine that has sold in the hundreds of thousands because it hits a genuine sweet spot between price, weight, and cutting power. For a typical quarter-acre to half-acre lot, it is often all the trimmer you actually need, and it undercuts the pro-grade models by a comfortable margin.
What Model Number 967628201 Actually Is
Retailers list the same trimmer under both its common name, the 129L, and its SKU, 967628201. They are the same product. It is a 2-cycle, gas-powered, straight-shaft string trimmer with a 28cc engine producing about 1.1 horsepower. The straight shaft matters: it gives you better reach under shrubs and decks than a curved-shaft unit, and it is the layout most professionals prefer for control and durability.
Out of the box it typically weighs around 8.6 pounds without fuel, which puts it on the lighter end of gas trimmers and makes an hour of edging far less punishing on your shoulders and forearms.
Key Specifications
Here are the numbers that matter when you compare it against a Stihl FS 38 or an Echo GT-225:
- Engine displacement — 27.6cc, 2-cycle
- Power output — approximately 1.1 hp
- Cutting width — 17 inches
- Line diameter — 0.095 inch recommended
- Fuel tank — 12.85 fl oz (0.4 liter)
- Weight — about 8.6 lbs dry
- Head — T25 semi-automatic bump-feed
That 17-inch cutting swath clears a surprising amount of grass per pass, and the T25 bump head is one of the easier ones to reload, which counts for a lot when you are three tanks into a long Saturday.
Who Should Buy It
This trimmer is aimed squarely at homeowners, not landscaping crews. It shines for anyone who wants gas power and reach without stepping up to the weight and cost of a commercial unit:
- Owners of typical suburban lots up to about half an acre
- Folks who fight thick fence-line grass and light brush that chokes a battery trimmer
- Anyone who dislikes recharging and wants to keep working as long as there is fuel in the can
- Buyers who want a straight shaft for edging clean lines along driveways and beds
If you mow acres or trim daily for a living, look at the pro-series 525L or 336FR instead. The 129L will do the work, but the commercial machines are built for that duty cycle.
Fuel and Oil Mix
Because this is a 2-cycle engine, you do not add oil separately the way you would with a 4-cycle mower. You premix oil into the gasoline. Husqvarna specifies a 50:1 ratio, which is 2.6 fluid ounces of quality 2-stroke oil per gallon of fresh 87-octane gasoline. Use gas with no more than 10 percent ethanol, and honestly, ethanol-free fuel or a canned pre-mix like Husqvarna’s own XP will save you a world of carburetor grief.
Mix only what you will burn in about 30 days. Old, ethanol-laden fuel is the single most common reason these trimmers refuse to start after sitting, because the ethanol draws in moisture and gums the tiny carburetor jets.
Starting and Break-In
The 129L uses Husqvarna’s Smart Start system with a reduced-resistance recoil, plus an air purge bulb that clears air from the fuel lines. A cold start sequence looks like this:
- Press the fuel primer bulb 6 times until you see fuel filling it.
- Move the choke to the full-choke position.
- Pull the starter cord until the engine fires and dies, usually 2 to 4 pulls.
- Move the choke to the half or run position and pull again to start.
- Let it idle 30 seconds to warm before squeezing the throttle.
During the first two tanks, vary the throttle rather than holding it wide open, and avoid extended full-throttle runs. This gentle break-in lets the piston rings seat properly and pays off in engine longevity.
Loading and Sizing the Line
Stick with 0.095-inch diameter line for this machine. Going thicker to 0.105 can bog the 28cc engine and stress the clutch, while thinner line snaps too fast in heavy grass. Round line is the default, but a twisted or serrated profile cuts thick weeds cleaner if that is your battle.
To reload the T25 head, you feed a length of line through the eyelets, center it, and wind it in the direction of the arrow on the head, leaving roughly 5 inches out each side. Bumping the head on the ground while the engine spins pays out fresh line automatically as the tips wear down.
Maintenance Schedule
A little routine care keeps this trimmer running for a decade or more:
- Every use — clear grass from the head and shield, check the line
- Every 5 hours — clean or tap out the foam air filter
- Every 25 hours — inspect and re-gap the spark plug to 0.020 inch, or replace it
- Seasonally — drain old fuel before winter storage or run the tank dry, and add fuel stabilizer if storing with gas
A fresh spark plug and a clean air filter fix the vast majority of hard-starting and stalling complaints people post online about this model.
Common Problems and Fixes
The most frequent gripes trace back to fuel. If it will not start after storage, the carburetor is almost certainly gummed by stale gas, and a carb cleaning or a $12 rebuild kit usually revives it. If it starts but dies at throttle, suspect a clogged air filter or a dirty spark arrestor screen in the muffler. If the line will not feed, the spool is either wound wrong or the head is packed with debris. None of these are the machine failing; they are maintenance items, and the 129L behind SKU 967628201 rewards owners who stay on top of fresh fuel and clean filters.
Attachments and Accessories
One point of confusion worth clearing up: the 129L behind SKU 967628201 is a fixed-shaft trimmer, not the attachment-capable 129LK. If you want the flexibility to swap in an edger, pole saw, or brush cutter head on the same power unit, you need the “K” model, which accepts Husqvarna’s click-on attachments. The straight 129L trims and edges well on its own but will not convert into other tools.
Useful accessories that do fit the 129L include a shoulder strap, which transforms comfort on longer sessions by taking weight off your arms, and a debris shield upgrade if the factory guard cracks. Replacement T25 heads and pre-wound spools are inexpensive, usually $10 to $20, and worth keeping on the shelf so a jammed head never ends your afternoon.
Comparing It to Battery Alternatives
Homeowners often cross-shop this gas trimmer against cordless models, so it helps to frame the trade-off honestly. The gas 129L wins on sustained runtime and raw power through thick fence-line grass, and it keeps working as long as you have fuel. Battery trimmers win on instant starts, quiet operation, and zero fuel mixing. If you have a large or overgrown property, the gas machine still has the edge; for a small tidy lawn, a battery unit may suit you better.
Storage and Winterizing
How you put the trimmer away at season’s end determines how it starts next spring. Stale fuel is the enemy, so before long-term storage, either run the tank completely dry or fill it with fresh fuel treated with a stabilizer. Running it dry is the surest way to prevent the carburetor jets from gumming, though some owners prefer stabilized fuel to keep the seals from drying out.
Follow these steps for trouble-free storage:
- Drain or stabilize the fuel as described above
- Remove the spark plug, add a few drops of oil into the cylinder, and pull the cord slowly to coat the piston
- Clean grass and debris off the head, shaft, and cooling fins
- Store it horizontally or hanging in a dry space away from temperature extremes
A machine put away this way fires up in spring with the same two or three pulls it did in fall, sparing you the frustration that sends so many neglected trimmers to the repair shop.
Final Verdict
For most homeowners, the husqvarna string trimmer #967628201 delivers reliable gas performance at a price, usually in the $170 to $200 range, that makes the pro machines hard to justify. It is light enough for extended use, powerful enough for fence-line brush, and simple enough to maintain with basic tools. Feed it fresh 50:1 fuel, keep the filter clean, and it will handle your trimming and edging season after season without complaint.
