This machine is quite flawless. However, there is an issue with its packaging which sometimes mentions parts that are not included with the trimmer, such as batteries. But WORX’s customer care is highly attentive and we would recommend contacting them in case of such a discrepancy instead of rejecting the product outright.

  • Good all-round performance
  • High-powered and versatile

Why Did We Like It?

This is one of the most impressive and affordable options when it comes to string trimmers. The 10 amp electric motor affords this model greater power than its predecessor, the 21212, and along with the 18-inch cutting swath, makes short of the most demanding lawns in no time.

Additionally, it features a 0.080 dual-line bump feed system that allows for quick line feeding, thus reducing the operational time to a remarkable degree. Also, being lightweight and compact, it is easily portable. However, don’t mistake its looks for a less-than-desirable capacity. The trimmer is fully optimized for heavy-duty tasks and will give you little to complain about.

If it could not get any better, we wouldn’t be featuring it. One of the major selling points of this unit is its exceptionally affordable price. With that array of functions, you would expect to shell out a few extra dollars. But Greenworks guarantees proficiency on a small budget, and while you’re here, mark this trimmer. It promises to be a worthy purchase.

What Could Have Been Better?

With such a wide variety of functions and a high degree of efficiency, it was hard to find faults with this product.

Why Did We Like It?

The WG154 is a lightweight, cordless trimmer that fulfills a two-pronged role and is aptly powered by a 20-volt battery in order to do so. It has a generous run-time that allows for prolonged work on most lawns and is also quite superior in its cutting capacity.

Speaking of cutting capacity, this trimmer features an adjustable cutting width from 10 to 12 inches for extended run-time and cutting path. Hence, the device is well-suited to the upkeep of unruly/overgrown lawns and also offers incredible precision. In addition to this, there is also an automatic single-line feed that enhances its operation.

Moreover, this trimmer easily converts to an edger and back. The rotating head allows for ease in the switch while the one-touch no-tool mechanism further simplifies the process. Among such essential features, what guarantees user comfort is the ergonomic design. As a compact device high on affordability, the WG154 is a cut above the average.

What Could Have Been Better?

The only minor issue this otherwise capable device faces is the charging time. At 5 hours, it could be considered long in comparison to most other models. However, we strongly feel it is in no way a dealbreaker and could be well overlooked given its capacity as a trimmer.

  • Suitable for prolonged use
  • Adjustable cutting height for precision
  • Ergonomic design
  • Long charging time
Dimensions: 47 x 11 x 10 inches | Weight: 6 pounds | Power Source: Battery-powered | Cutting Width: 10 – 12 inches

Two other features that made an impression were the PowerCommand dial and the PowerDrive transmission. The former gives you a power range to choose from – from 8500 RPM to 6500 RPM, while the latter offers increased cutting force. Further, the head of the trimmer can be rotated up to 180 degrees, which allows for tool-free conversion from cutting to edging.

Buying Guide For The Best String Trimmer 

A string trimmer comes in to fill the gaps in a lawn mower’s performance. Think leftover weeds, unsightly flowers, and the untrimmed edges of your fences. The ideal trimmer rids your lawn of such minute unwanted elements and keeps it looking perfectly manicured.

However, with the variety of good-quality trimmers in the market, it may be difficult to pick the right one. So we have compiled a brief guide for you listing the factors to keep in mind while making your selection.

String Trimmer Power source

The two kinds of models are: gas-powered and electric. Gas-powered models offer great power in their performance and are ideal for larger lawns, thus being well-suited to the needs of professional landscapists. However, they tend to be priced higher on the scale, are heavy, and often lead to air and noise pollution.

Electric motors, on the other hand, are lightweight and more affordable and come in both corded and cordless models. The only drawback is that they are not suitable for very large properties and heavy-duty tasks.

Cutting Width

The dimensions of the cutting diameter correlate to how wide a swath the trimmer can cut, and this value usually ranges from 10 to 18 inches. Obviously, for medium to small-sized lawns, a compact cutting width is ideal while larger properties are best left to models with at least a 16-inch wide cutting width.

String Trimmer Shaft Style

Straight, curved, and adjustable – the three styles come with their unique pros and cons. A straight shaft is ideal for trimming tight and narrow spaces but can be unwieldy to handle. Curved shafts are also well-suited to hard-to-reach spots and offer greater control in cutting, but may pose difficulties in maneuverability.

Both straight and curved shafts can be adjustable which allows for height adjustments, primarily. This results in greater precision in trimming and also optimizes the trimmer for multiple users.

Single or Dual Feed Line

Single-line heads are easier to wind and operate, which makes them ideal for smaller spaces. They are also the more convenient option to go for while installing a new trimming line. On the other hand, dual lines cut twice with each revolution and are best suited to heavy-duty tasks on larger lawns.

Grass Trimmer Weight

Weight is a major factor that can affect the performance of your string trimmer. It is only practical to ensure the ideal weight as the device must be easily portable no matter the size of your lawn. With weights ranging from 5 lbs to 20 lbs, it may be hard to pick the right trimmer for your purpose.

Gas-powered models, although more efficient, weigh considerably more than their electric counterparts. On the other hand, lightweight corded models tend to compromise on power output. For medium-sized lawns, we would recommend a cordless trimmer that balances capacity and weight, while leveraging the best of both.

Frequently Asked Questions

What is the difference between a curved and straight shaft trimmer?

A curved shaft trimmer is more suitable for trimming around objects, whereas a straight shaft trimmer is more suitable for reaching under bushes or cutting the edge of lawns.

Is a cordless string trimmer better than a corded one?

Cordless string trimmers are more convenient since they don’t require a power outlet or a cord to tether to the tool.

However, corded trimmers have a more consistent power output and are better suited for larger lawns with thicker vegetation.

What is the average lifespan of a string trimmer?

The average lifespan of a string trimmer is approximately five years, but this varies depending on the brand, the type of trimmer, and how well the tool is maintained.

What is the maximum cutting diameter of a string trimmer?

The maximum cutting diameter of a string trimmer is typically between 12-15 inches, although some models may have a larger cutting diameter.

How do I maintain my string trimmer?

To maintain your string trimmer, keep it clean and free of debris, regularly check the air filter and spark plug, and follow the manufacturer’s instructions on oil changes and other maintenance tasks.

Ensure that you use the right type of string for your trimmer and store it in a dry place when not in use.
