What to Look Out for When Shopping for The Best String Trimmer

String Trimmers Gas Powered

A string trimmer is used to fill in the gaps left by a lawnmower. Consider overgrown weeds, ugly blooms, and untrimmed fence edges. The ideal trimmer keeps your lawn appearing precisely maintained by removing such minute undesirable features.

However, with so many high-quality trimmers on the market, choosing the ideal one might be challenging. As a result, we’ve put together a quick guide for you that outlines the variables to consider while making your decision.

Source of Energy

There are two types of models: gas and electric. Gas-powered models provide a lot of power and are suitable for larger lawns, so they’re perfect for professional landscapers. They are, however, more expensive, heavier, and frequently contribute to air and noise pollution.

Electric motors, on the other hand, are smaller and less expensive, and are available in both corded and cordless versions. The sole disadvantage is that they are not appropriate for large properties or heavy-duty tasks.

Width of Cut

The width of the swath the trimmer can cut is determined by the cutting diameter, which typically runs from 10 to 18 inches. Obviously, a compact cutting width is preferable for medium to small lawns, while bigger properties should choose for models with at least a 16-inch wide cutting width.

Shaft Design

Straight, curved, and adjustable – each style has its own set of advantages and disadvantages. Straight shafts are good for trimming small and narrow locations, although they can be awkward to use. Curved shafts are also good for hard-to-reach places and provide more cutting control, although they can be difficult to manage.

Straight and curved shafts can both be adjusted, allowing for primary height modifications. This improves trimming precision while also optimizing the trimmer for various users.

Single or Dual Feed Line

Single-line heads are easier to wind and operate, making them appropriate for places with limited space. They are also the more practical choice for adding a new trimming line. Dual lines, on the other hand, cut twice with each revolution and are suitable for heavy-duty work on larger lawns.


The weight of your string trimmer can have a significant impact on its performance. Because the gadget must be conveniently portable regardless of the size of your lawn, it is only reasonable to assure the right weight. It can be difficult to choose the proper trimmer for your needs with weights ranging from 5 to 20 pounds.

Although more efficient, gas-powered vehicles are significantly heavier than their electric counterparts. Lightweight corded devices, on the other hand, frequently sacrifice power output. We recommend a cordless trimmer for medium-sized lawns that balances capacity and weight while utilizing the best of both.

Frequently Asking Question

What Trimmer Line Do Professionals Use?

It’s inexpensive, lightweight, and long-lasting, with high tensile strength. Because of the low cost of nylon lines, most commercial trimmers and professional landscapers utilize them. Nylon is a versatile material, although it lacks the strength of copolymer and titanium lines.

Is Thicker Trimmer String Better?

This should come as no surprise, but when it comes to string trimmer line, the thicker the line, the harsher the application. A wider diameter increases the line’s power and durability, resulting in reduced breakage and wear-out.

Is A String Trimmer Worth It?

It’s the perfect tool for tidying up the edges of your garden or sidewalk, as well as around fence poles and tree trunks. It can also handle long grass and weeds, which would bog down a traditional lawn mower. Light brush can also be cleared with a string trimmer.

Should You Soak Trimmer Line In Water?

Trimmer line tends to dry out and grow brittle over time. It can be stored or soaked in water to help decrease line breakage and increase flexibility. Before you buy new line and start using it, be sure you’ve used up your stock of last year’s line.

Why Does My Strimmer Wire Keep Snapping?

This is usually caused by the cutting head being too close to obstacles, such as garden stones, paving edges, and walls. The cutting line must be able to freely rotate and must be of the proper diameter and kind.

Final Verdict

While string trimmers are affordable gardening machines that make short work of manicured and unkempt lawns, choosing the perfect machine for your yard isn’t a walk in the park. We have collected some of the best models available on the market, which should help you make an informed purchasing decision.
