If you have a 0.25 acre lot or smaller, and you want a durable electric string trimmer with no fuss, no muss, than the Dewalt DCST920P1 is just right. Its design is simple but efficient, with a variable speed trigger that goes between high and low, maximizing power or runtime. We liked the simplicity of the bump feed that requires just a tap on the ground to advance the line while the trimmer is running. Another advantage is the easy maintenance; the only thing we saw that this trimmer needed was keeping the line cutter sharpened and keeping the extra line in a moist bag to preserve it. For long-term storage, the battery has to be kept in a temperature-controlled environment so as not to wear it out. We would have preferred the stronger 0.095″ line for its extra strength, but this trimmer still works as advertised and handles small to mid-size lots well.

For those who swear by the incredible power and durability of gas trimmers, the Toro 51978 definitely won’t disappoint. This model, with its 2-cycle 25.4cc engine, makes mincemeat of weeds and brush in short order. Additionally, the straight shaft allows users to reach around obstacles like porches and fences. We saw no issues with the 0.095″ dual line, which seems to be made to deal with abuse and not wear out quickly. If there are any issues with this model, it’s that at 12.5 pounds, it’s heavier than some other models and wears out your arm over long periods of use. Also, the debris guard is on the flimsier side and doesn’t keep debris from shooting all over the place, so be prepared with heavy-duty clothes that you don’t mind getting dirty.

The Ryobi RY40220 is a cordless weed eater that, like the Black & Decker LST136W, avoids the hassle of maintaining a gas trimmer and still provides great cutting power in a lightweight body. We were impressed with the strength of the 0.080″ dual line, which handles even the toughest weeds, brush, and grass fairly easily. Another plus that we noticed quickly was the noise—or lack thereof. If you’re the kind who likes to do yardwork early in the morning before the heat of the day, then you can do so guilt-free knowing that you won’t disturb the neighbors. We would have liked to see more thought put into the ergonomics of this model; having length adjustment would prevent users from having to lift the trimmer and putting stress on their arms. However, the long runtime and the ability to switch between different attachments will make tending the lawn much more convenient.

We were pleasantly surprised by many of the EGO Power+ 56V string trimmer’s features, which include a fast-charging battery that provides up to an hour of powerful, efficient trimming. As soon as we held it, we were pleased with the lightweight, well-balanced design of this model, as we could tell that it would take a lot of the hassle out of yardwork. Indeed, the 0.095″ line can handle a lot of tough jobs, and we saw no problems with the bump feed head as the trimmer ran at maximum speed. Another convenient feature is the variable speed, because it allows you to work most efficiently, for instance, switching from a low setting for trimming grass to a high setting for the tough weeds. A possible downside to the incredible power, however, is that debris flies in all directions, making it essential for users to wear long sleeves and pants, closed-toe shoes, and protective goggles.

If you’ve had enough of maintaining a gas-powered weed eater and are looking for something user friendly, the Black and Decker LST136W is a great cordless, battery-powered edger that doesn’t sacrifice on power. Its 40V lithium battery charges in under an hour and will last at least an hour on a low to medium power level. We liked having the option to turn the dial between maximum power and maximum runtime. On maximum power, the weed eater lasts about 15 minutes but can handle tougher brush. For regular lawn trimming and taking care of weeds, the lower power setting is more than adequate. On the negative side, the trimmer line can dry out and become brittle, and its thin diameter of 0.065 inches puts it at risk of breaking should it hit solid surfaces like the pavement. Overall, however, this weed eater’s precision, convenience, and power make it a solid purchase.

Another cordless string trimmer ideally suited for small to mid-size yards, the ECHO CST-58V4AH runs efficiently by letting you switch between the high and low power setting. We found that the bump feed head worked great at reloading the line, which is quite durable as a 0.095 and 0.080 inch twist line. Another convenient feature was the fairly long battery runtime, which can easily top an hour if used on the lower power setting. One thing we would have liked to see addressed is the balance; the trimmer feels heavier in the back than in the front, giving it a slightly awkward feel over long periods. However, the fact that this trimmer takes out the hassle of storing and mixing gas and complicated maintenance makes this a worthy purchase.

For a behemoth gas trimmer that’s definitely a step up from the standard 25cc trimmer, the Honda HHT35SLTAT demonstrates its incredible power from the moment it starts up. Although it’s on the heavy side, this model has a shoulder strap and is designed to not vibrate so much, so it’s not exhausting to use for long periods of time. One of the advertised perks of this model is the fact that it doesn’t make you mix gas and oil but takes regular gas, which certainly takes a lot of the hassle out of operating a gas trimmer. Another nice feature is the collection of blades and add-ons to increase the utility of this trimmer. If we have complaints, it’s that it takes more than one or two pulls to start up, and its fuel efficiency is not as great as 25cc models. Still, we can’t fault the design or the quality of this Honda trimmer.

Lawn trimmers are invaluable tools for keeping your yard looking tidy and professional. Trimmers can reach tight areas that lawn mowers can’t, such as beneath bushes and around trees. Many trimmers also function as edgers, allowing you to get a clean, straight line along sidewalk paths and garden beds. As we examined different lawn trimmer and lawn edger models, we kept the following qualities in mind:

1. Durability
2. If cordless, battery life
3. If gas-powered, gas efficiency
4. Ease of start-up
5. Weight and maneuverability
6. Power to cut through tough weeds
7. Guard for safety
8. Head width
9. Accessories
10. Price

Choosing a Lawn Trimmer

Gas vs. Electric Lawn Trimmers

As with many other tools, one of the major considerations you’ll face as you select a lawn trimmer is whether to go gas or electric. Each option has its pros and cons, so you’ll have to think about your personal needs and preferences.

Power
Gas lawn trimmers are typically more powerful than electric ones, so keep that in mind if you have a large yard or rough, thick terrain. On the other hand, electric weed eaters are usually quieter and more lightweight.

Cords and Batteries
Gas lawn trimmers are cordless, giving you a wide range of movement. Electric lawn trimmers come in corded or cordless varieties. If you choose corded, make sure you have easy access to an outdoor power outlet. If you choose cordless, research how long a battery charge will last you—you’ll want to be able to finish your yard without having to stop and recharge the lawn trimmer.

Maintenance
Generally, electric lawn trimmers are easier to maintain than gas lawn trimmers. Many gas weed eaters, particularly those with a 2-cycle engine, require you to mix gas and oil together for fuel. However, you can select a lawn trimmer with a 4-cycle engine, which doesn’t require that gas-oil mixture.

In short, if you have a smaller yard, or you trim less frequently, then an electric lawn trimmer may be the better, more economical choice. If you require a more powerful machine to cut through tough brush or heavy grass, you’ll likely prefer a gas lawn trimmer for its extra oomph.

In order to get a crisp edge along walkways, hold the lawn edger so that the blade falls between the grass and the sidewalk. Work slowly and in a straight line to achieve a neat, uniform look.

Safety
Safety precautions are important. Always wear long pants, socks, and sturdy shoes when you work. While you should avoid edging near rocks and other hard objects, eye goggles can give you the protection from any flying debris. Gloves are also ideal if the edger’s vibrations give you blisters or tire your hands.

Frequency
Luckily, edging only needs to be performed once or twice a season. Any more than that, and you may end up with weaker, stiffer grass. Following the recommended guidelines for edging will help you achieve the professional-looking lawn you desire.

If you have a small yard or if you need a lawn trimmer only for occasional light work, then the Black & Decker ST1000 is an affordable option at just $19.97. As its blade cuts grass in 9-inch swaths, it allows you greater control and maneuverability. One convenient feature we liked was the bump feed spool, which feeds you only as much line as you need. For a lightweight lawn edger, this Black & Decker model can cut through thick, tall grass fairly easily. One downside is the lack of a guard, so be prepared for grass clippings to come spraying your way.
