After testing the weed whackers on five different lawns and at a city park, we agreed that the Hitachi CG23ECPSL is the best weed whacker overall because of its light weight, power, anti-vibration system and cutting capability, but the Toro 51978 is a very close runner-up. The Toro is a bit heavier but does an equally good job cutting grass. The Hitachi effortlessly cut its way through thick weeds and grass and even took down tough, reedy vegetation. The 60-inch shaft makes it easier on taller users and gives a person of any height longer reach.

Best Overall
The Hitachi CG23ECPSL was the best weed whacker overall in our extensive testing. Our reviewers cut through thick grasses and even reedy vegetation with ease, and it was easy to angle the machine to use it as an edger along sidewalks and driveways.
This gas-powered trimmer has a 60-inch shaft, which made a world of difference for the backs of our taller reviewers, since they didn’t have to slouch or overextend to reach the weeds and grass. Our shorter reviewers had a slightly harder time getting used to the longer shaft, but they quickly adjusted and commented that it was nice to be farther away from the flying grass and debris. An additional comfort feature of this Hitachi weed whacker is an excellent anti-vibration system that reduces the shaking produced by the engine and spinning spool. This makes it possible to trim longer with less fatigue in your hands and arms. In addition to trimming, Hitachi offers various attachments, sold separately, that can attach to the front of the CG23ECPSL, such as an edger, pole saw and hedge trimmer. We are particularly impressed at how powerful this weed eater is, considering it only weighs 10.3 pounds. It is also well-balanced and was one of the most comfortable machines in our testing.
Pros
  • 60-inch shaft gets to hard-to-reach areas
  • Lightweight and balanced
  • Anti-vibration system is easy on hands and arms
Cons
  • Spool can hold only 13 feet of string
  • Longer shaft can be difficult for shorter people
  • Does not include a shoulder strap

Best Value
While the Ryobi RY253SS is not the least expensive weed whacker we reviewed – the Homelite UT33650 and the Weed Eater W25SFK cost less – the Ryobi performed better in our tests overall than those two products and is a more versatile tool. You can switch out the battery with other Ryobi electric tools, and it support attachments to double as an edger, blower and tiller.
Our testers remarked that the Ryobi had above-average cutting power and that the 18-inch cutting path made their work easier. Ryobi backs this gas-powered weed trimmer with a three-year warranty, better than the industry standard of two years, and you can find Ryobi attachments and parts at your local Home Depot. While not as light as our overall best pick, the Ryobi weighs around 12 pounds, which is standard for a trimmer with its engine size and power. Unfortunately, this weed whacker does not have an anti-vibration system to reduce the shaking generated by the engine and the spinning of the string spool. Our testers noted that their hands fatigued sooner with the Ryobi than with our top models, though the amount of vibration generated wasn’t above normal expectations. The straight shaft measures 40 inches, giving you plenty of range for hard-to-reach areas, such as around shrubs and bushes. Some of the attachments available (sold separately) include a blower, edger and tiller. These attach at the end of the trimmer where the head is located, rather than halfway down the shaft like some other models, giving you the advantage of the machine’s full length.
Pros
  • 18-inch cutting path
  • Compatible with multiple attachments
  • Three-year warranty
Cons
  • Weighs over 12 pounds
  • No anti-vibration function
  • Heavy engine balance is tiresome for long jobs

Best for Low Vibration
The Toro 51978 is the best weed whacker for low vibrations, thanks to its excellent built-in anti-vibration system. Of the weed eaters we tested, the Toro was among the top for performance and comfort in use.
Our reviewers were impressed with its ability to cut through tough lawn vegetation while remaining balanced throughout our rigorous tests. This gas-powered weed whacker cuts an impressive 18-inch path and has a 44-inch shaft, which makes it easier to reach behind bushes, posts and trees. Toro itself does not manufacture attachments, so if you want an edger, blower or pole saw, you have to look elsewhere. Fortunately, the Toro can use other brand name attachments – as long as they use a universal connector – without voiding its warranty. This is a great value if you already own multiple attachments but need a stronger weed whacker. It can also potentially save you money since you can shop for the best attachment deals, regardless of brand. One of the only downsides to the Toro 51978 is that it weighs 12.5 pounds, which is quite heavy for extended use. You can purchase a neck strap separately to alleviate some of the weight, but for a small or medium-sized yard, it shouldn’t be necessary.
Pros
  • Can use many attachments from other brands
  • 18-inch cutting path
  • Spool can hold up to 25 feet of string
Cons
  • Has the heaviest engine of all the models we tested
  • Shaft length is not optimal for taller people
  • Weight can tire users quicker

Largest Engine
The Snapper 41ADZ24C707 has a powerful 27cc engine. The more cubic centimeters in an engine, the more power it will have, and this has the most of any in our comparison.
The Snapper’s dual feed and 17-inch cutting radius will blast through a big patch of weeds quickly. It has some nice features like an adjustable handle and trigger control that lets you turn it off and on with the simple push of a button. While it’s easy to use, this trimmer did take longer than average to assemble. It has a shoulder strap that makes it easier to carry around the yard and helps it run more smoothly. This is nice especially since it lacks antivibration technology. Snapper doesn’t make its own attachments, but it is compatible with third-party accessories like a brush blade, pole saws and leaf blowers, making it a multifunctional tool.
Pros
  • The trimmer has a powerful 27cc engine and a wide cutting path.
Cons
  • It took longer than average to assemble.

Best for Attachments
The Troy-Bilt TB32 EC has controls that are easy to use and a generous 17-inch cutting path to help you get through a lot of weeds fast.
The handle adjusts easily, and you simply bump the head to get more line when it gets low. This gas trimmer lets you add attachments so you can do all kinds of landscaping tasks around the yard using the same tool. These attachments include a leaf blower, a tiller and a hedge trimmer to name a few. You can even purchase an AeroFlex trimmer head that has fixed blades that are more durable than the dual-feed line. This gives you more precise control for cutting tough grass, weeds and heavy vegetation. During testing this trimmer vibrated more than average. It would have been nice if there were a shoulder strap to help steady it, but unfortunately that wasn’t included in the package.
Pros
  • This weed whacker lets you add attachments to help with all types of landscaping chores.
Cons
  • This trimmer vibrates quite a bit during operation.

Why Trust Us?

Top Ten Reviews has tested weed whackers for over six years. Our expert reviewers have trimmed, cut and tested with over 60 models during that time to find the machines that perform the best.

After completing our testing, we determined which tool works best for tall, strong users; which trimmer was the most comfortable to use that didn't leave us feeling shaky; and which tool is best for shorter users with smaller hands. Our tests identified the tools that cannot eradicate thicker weeds but might work satisfactorily for your yard if you don't require a more powerful engine.

How We Picked the Best

We took 10 weed whackers to five lawns and a city park to test their functionality. A trimmer should be powerful enough to cut through the thick brush in your yard with only a few passes, so our testers used each trimmer in a series of practical, everyday tasks and some controlled tests to determine which ones performed the best.

For design, we measured the decibel level of each trimmer running at full throttle. We measured the shaft length, the cutting path and the weight. To make sure we catered to all body types, we enlisted the help of several testers of varying height, weight and strength to determine how the balance and weight of each weed whacker worked for them. Exposure to vibrations for a long period of time can be potentially damaging, so we also asked the testers to rate the level of vibration they experienced while using the weed whackers.

How Much Do Gas Trimmers Cost?

Gas trimmers generally cost more than electric trimmers. The least expensive models in our lineup are in the $100 range. The cheapest gas trimmers we found online were about $70, but those are the exception. Most gas trimmers cost around $130 up to more than $200. In contrast, corded electric trimmers have many cheaper options. You can find good corded trimmers for $50 or less. Battery-operated electric trimmers can cost as much as gas trimmers, but there are more options in the $60 to $90 range.

What Else Is Important When Selecting a Weed Whacker?

Below are some other considerations when selecting your next weed whacker.

String Features: How Easy Is It to Replace the String, and How Long Does It Last?
All weed whackers use some variation of a wound-up spool of string, which is enclosed in a case inside the trimmer, to knock down tough grass and weeds. This string wears out and needs to be replaced, often several times in one session. String reloads from the case in a few distinct ways: Semi-automatic models have string that adjusts on its own. Most models require a bump, meaning you need to knock the bottom of the weed trimmer against the ground to activate a button at the bottom that feeds out additional string. Manual-feed models require that you stop trimming, turn over the unit and pull the string out manually.

You want to pay attention to the amount of string the case holds. The more feet of string you have, the longer the weed whacker will work before you need to purchase replacement string, which can be expensive.

Final Thoughts

If you have a smaller yard or you don't need to do yardwork weekly, an electric string trimmer could be a good fit for you. And if you want to fill up your tool shed, be sure to also check out the top 10 gas lawn mowers and eco-friendly electric lawn mowers.

All the weed whackers we tested are good choices, depending on your needs, so read through our comparison chart and reviews to find the gas-powered weed whacker that works for you.
