Quick verdict
For most homeowners with a large yard, the Husqvarna 330LK is my top gas string trimmer. Its straight shaft and 20-inch cutting width cover ground fast, the Rapid Replace head makes reloading line simple, and the spring-assisted start eases the pull.
Husqvarna 330LK Gas String Trimmer
The 330LK runs a 28cc 2-cycle engine and lets you set the cutting width to 20 inches for open ground or 18 inches for thicker growth. A spring-assisted starter cuts pull effort by about 30 percent, and the Rapid Replace head makes line reloading quick. Its detachable shaft accepts a range of click-on attachments.

Why you should trust this guide
I put this guide together by gathering the gas string trimmers homeowners and property owners actually shop for, then working through the published engine specs, shaft types and feature lists for each one. My aim is to steer you toward the right tool for the size of your yard and the toughness of your weeds, not toward whatever has the loudest listing. I do not take payment to rank a product higher.
Every model here is a real, current listing with a verifiable engine displacement. Where a spec is not published, I say so rather than guess. I also flag when a tool is really a multi-function machine or leans toward heavier or lighter duty, because a mismatch between engine size and the work you are doing is the most common regret with gas trimmers.
How we evaluated
My evaluation centers on the criteria that actually decide performance: engine displacement in cc, whether the shaft is straight or curved, the cutting width, the starting system, and how line is fed. Bigger engines and wider swaths clear tough ground faster, a straight shaft reaches farther under obstacles, and an easy-start system saves you the frustration that gives gas tools their reputation.
I also weigh versatility and comfort, since attachment capability, anti-vibration features and included harnesses change how a trimmer feels over a long session. I did not bench-test these units, so I am upfront that these judgments come from the manufacturer specifications and design details rather than my own stopwatch or scale.
What to look for
- Engine size: Measured in cc. Around 22cc suits homeowner grass and light weeds, while 28cc and up handles larger properties and denser growth.
- Straight vs curved shaft: Straight shafts reach under bushes and suit taller users and brush-cutter blades. Curved shafts are lighter and easier to maneuver around obstacles.
- Cutting width: A wider swath, such as 17 to 20 inches, clears open ground in fewer passes.
- Starting system: Look for spring-assisted or smart-start features and air purge, which make a 2-cycle engine far easier to fire up.
- Line feed: Tap-and-go and rapid-replace heads make reloading line quick, which matters on big jobs.
- Attachment capability: A detachable shaft lets one powerhead run edgers, pole saws and brush cutters, though attachments usually cost extra.
- Fuel type: 2-cycle engines need oil mixed into the fuel, while 4-cycle engines run straight gasoline with separate oil.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

What to look for
Size the engine to the yard
A 22cc engine is fine for homeowner grass and edges, but larger lots and thick weeds are much easier with 28cc or more.
Shaft shape changes reach
Straight shafts give better reach under bushes and are needed for most brush-cutter blades, while curved shafts feel lighter and turn more easily around obstacles.
Starting matters more than you think
The biggest complaint with gas trimmers is hard starting. Spring-assisted pulls, smart-start systems and air purge make a real day-to-day difference.
Line feed convenience
Tap-and-go and rapid-replace heads let you refresh cutting line quickly instead of stopping to disassemble the head.
Versatility versus simplicity
Attachment-capable powerheads and multi-tool kits do many jobs but weigh more. If you only cut grass, a dedicated trimmer is lighter and simpler.
Fuel mixing
Most trimmers here are 2-cycle and need a precise oil-to-gas mix. A 4-cycle option runs on straight gasoline if you prefer to skip mixing.
Our verdict
For most homeowners with a large yard, the Husqvarna 330LK is my top gas string trimmer. Its straight shaft and 20-inch cutting width cover ground fast, the Rapid Replace head makes reloading line simple, and the spring-assisted start eases the pull.
FAQs
For large properties and thick weeds, gas still offers longer run time and more cutting power. For small yards, cordless is quieter and simpler, so it comes down to the size and toughness of your work.
Around 22cc handles homeowner grass and light weeds. For big lots, dense growth or a brush-cutter blade, step up to 28cc or larger.
A straight shaft reaches farther under bushes and supports brush-cutter blades, while a curved shaft is lighter and easier to maneuver around obstacles.
The 2-cycle models here require oil mixed into the gasoline, typically at a 50:1 ratio. A 4-cycle engine runs on straight gas with the oil kept separate.
Yes. Several models here accept attachments or come with brush-cutter blades, letting a single powerhead handle trimming, edging and clearing thicker growth.
