Best Dual-Duty String Trimmer and Edger

    The BLACK+DECKER is both comfortable and effective, pulling double duty as a string trimmer and edger.



If you’re looking for a string trimmer that doubles as an edger, the Black+Decker LSTE523 is the prime choice. It quickly converts from a trimmer to an edger with wheels, giving you more flexibility. Equipped with a 20-volt battery, this product lasts long enough to get a small yard done on one charge. If you have a larger yard, you can switch the trimmer from power transmission to extended run time.

When you run out of line, it’s easy to get more string. You simply push a button and more line comes out. There’s also an adjustable handle that allows for a more comfortable experience. If you have a large yard, the adjustable-height and soft-grip handle makes the job seem less difficult. It’s relatively lightweight, which also contributes to a more comfortable experience. For a trimmer that’s both comfortable and effective, this product is a top choice.

Best Gas Edge Trimmer

Husqvarna 128CD
    Husqvarna's powerful gas edge trimmer is a great choice if you need to cut through high grass and weeds.



Some people prefer gas trimmers, and this Husqvarna is an example of what edge trimmers should be. This product has a 28cc, two-cycle engine. With such power, it’s able to cut through tall grass. It has a 17-inch trimmer head, which covers enough ground to make quick work of your yard chores.

Due to the curved shaft design, this product has an even weight distribution. Even though it’s heavier than most electric models, this trimmer is balanced enough to keep you comfortable.

The real highlight of this trimmer is its versatility. You can remove and replace the trimmer head with other attachments. If you want to use it for other purposes, you can buy an edger head, pole saw head, or a cultivator. If you’re interested in a multi-purpose trimmer that has some serious power, the Husqvarna 128 CD should be your go-to. It may be expensive, but it means you won’t need to buy a shed full of yard machines.

Best 3-in-1 Electric Trimmer

WORKPRO 20V Cordless String Trimmer/Edger
    Not only does the WORKPRO work as an edger, trimmer, and mini-mower, it's also the most lightweight product in our list.



One of the most innovative electric edgers out there, the WORKPRO 20V Cordless String Trimmer/Edger is much more than a simple edging or trimming tool. It also works like a mini mower that allows you to cut your grass lower to the ground than a regular mower, and without making the mess of using a trimmer to take the grass down to the dirt.

Both lightweight and maneuverable, this cordless lawncare tool weighs only three and a half pounds without the battery, and around five with the battery. It’s powered by a 20V Li-ion battery that gives you around half an hour of run time in between charges. Charing takes right at one hour. That said, the unit has excellent torque and power for an electric model.

An automatic feeding spool makes the trimmer easy to maintain, and the push-button spool system spits out more line with the bumping necessary. The ergonomic handle is built with people of various sizes in mind and is fully adjustable. The unit also includes a flower guard to help protect your landscaping while getting in close for trims and edging.

Most Versatile Electric Edge Trimmer

Greenworks 24V Cordless String Trimmer/Edger

Thanks to a brushless motor, this product has extra torque and an increased lifespan. It’s quieter than most other models of trimmers – a trait your neighbors might thank you for. With a 12-inch cutting swath, this product is great for detailed areas.

The battery on this trimmer lasts for about half an acre of trimming or 60 minutes. As an added bonus, the battery comes with a USB port. You can use it to charge your phone or tablet. If you have any other Greenworks products, you can use the trimmer’s battery to power them.

Weighing in at just under 9 pounds, this trimmer is light enough to make your trimming seem easy. It also has a cushioned grip. If you’re looking for an electric trimmer that’s as versatile as it is effective, choose the Greenworks String Trimmer.

Best Budget String Trimmer and Edger

WORX WG154 Edger
    This affordable edger and trimmer comes with an energy-saving feature and weighs in at only six pounds.



Like some of the other options on this list, the WORX WG154 is a string trimmer and edger combined. It converts quickly, making it easy to use. Although the battery doesn’t last for long, you can save yourself some juice by switching to the energy-saving mode. The cutting head drops from 12-inches to 10-inches, which demands less power.

Because this trimmer only weighs six pounds, almost anyone can use it without too much exertion. The low weight also makes it easy to maneuver. If you’re worried about damaging your flowers, you can use the adjustable spacer for protection. To remove the spacer, you simply flip it up.

This product is easy to use and comes with an ergonomic handle. Although it’s priced lower than most other string trimmers, this trimmer doesn’t skimp on comfort. If you’re looking for a budget-friendly string trimmer that is easy to use, then the Worx WG154 should be at the top of your list.

How to Choose the Best Edge Trimmer

Man using a Husqvarna edge trimmer to trim the lawn.

Before you start shopping around for your lawn equipment, there are a few things you should know. By understanding how trimmers work and how to pick one that meets your needs, you can make the best purchase for your home. Then, you can enjoy your backyard.

What Is the Difference Between a Trimmer and an Edger?

Many people use the terms “edger” and “trimmer” interchangeably. However, they are two different pieces of equipment. They are similar in that neither is used to mow a lawn and both are used to keep your yard looking precise. However, the similarity ends there.

When a lawnmower can’t cut the grass in a tight spot, a trimmer takes on the job. Typically, homeowners use trimmers for fence lines, under decks, and near gardens. An edger is more limited in that it’s used to tidy borders, such as the area along your sidewalk or driveway.

Types of Trimmers

trimming edge of lawn with edger at curbTrimmers are extremely diverse. For instance, you can choose whether you want a gas trimmer or an electric trimmer. Gas trimmers are available as either two-cycle or four-cycle models. If you get a two-cycle, you need to mix together oil and gas. Meanwhile, a four-cycle trimmer only relies on gasoline.

No matter which type you choose, you’ll be able to select a certain type of shaft. Each shaft type is equipped for certain jobs. A trimmer with a curved shaft is usually better for small yards that demand precision. If you have plenty of landscaping, a curved shaft trimmer could be the best option.

For larger yards, a straight shaft trimmer is more appropriate. It’s more effective at reaching under objects, like decks and large bushes. If you have a tall stature, this type of trimmer may be more comfortable than a shaft trimmer.

How Do Edge Trimmers Work?

A trimmer is a simple machine, but it can make your life so much easier. Originally invented in the 1970s, the machine has evolved over time. However, it still relies on basic principles to keep your grass well-manicured.

When you use a trimmer, a thin cord spins at a high speed. It spins so fast that the cord becomes tight and stretched. Because of this, the cord is able to cut through blades of grass.

That said, some heavy-duty edgers use small metal blades rather than a string. These blades allow the machine to not only cut grass and weeds but to dig into the dirt as well.

Can You Edge With a Trimmer?

You can edge your lawn with a trimmer, but you cannot trim your lawn with an edger. That said, there are some machines that double as both trimmers and edgers. Some trimmers are more difficult to edge with than others. Before buying a trimmer, you should consider how well the machine will handle edging if you intend on using it for both purposes.

Should You Edge Your Driveway?

If you don’t edge your driveway, you’ll end up with grass that’s longer on the border. For the best results, you should use a trimmer or edger to keep your grass low. Most mowers aren’t able to keep the boundary between your driveway and your lawn clean. It takes a little extra time to edge it, but your effort pays off. At the very least, your neighbors will definitely notice it!

Should You Edge Before Mowing?

There’s no rule that says you need to edge before you mow your lawn. However, it’s a good idea for you to be in the habit of edging before you mow. This is due to the fact that edging after you mow makes a mess. If you edge first, your mower will collect most of the trimmings. Edging before mowing also provides you with clear guidelines along paths, flowerbeds, gardens, and driveways.

How Can I Edge My Lawn Without an Edger?

If you have a trimmer, you may not need an edger to edge your lawn. You can simply take your trimmer and use it to get a clean cut along your borders. Just be careful, because not all trimmers work well for this job.

To get started, take your trimmer and turn it on its side. Make sure the string is pointing away from you, or you risk being hit by debris. Take the shaft and place it on your shoulder, then move the trimmer along the edges of your borders. By holding it this way, you can maneuver the trimmer with the precision you need.

How Do I Keep My Yard Edges Neat?

Keeping your edges neat only takes a little effort each time you mow your lawn. First, you should find a way to clearly define your edges. You could use a landscape border to create a visible border between your grass and other surfaces.

If you don’t edge on a regular basis, your border will disappear and grass will spill over your barrier. Every time you mow your lawn, be sure to use the trimmer.

What Is the Best Edge Trimmer for You?

Are you still wondering which is the best edge trimmer for the job? The Greenworks String Trimmer is a clear winner, in our humble opinion. Although it’s not gas-powered, it still has some significant power behind it. What makes this even more valuable is the fact that you can use other heads to convert the trimmer into different yard tools as well.

The lightweight of the product means that you won’t tire out, and the ergonomic design adds to your comfort. Between its versatility and ease of use, this trimmer does not leave much to be desired. The lengthy battery life makes up for the fact that it’s electric.

The bottom line? This unit can handle all of your edging and trimming needs, period.
