When it comes to keeping your lawn in great shape, trimming and mowing go hand in hand—but there are some parts of your garden that even a mower can't reach. That's where a weed trimmer comes in. Let's face it: whether it’s a nook, cranny, or a very particular way you’ve planted flower beds, weeds are going to sprout. Not only that, but they pop up in every possible part of your lawn you don’t want them to. This is why a weed eater is a great tool to prune your yard and keep it in pristine condition. Instead of using chemical-based products that not only kill the ground and grassroots, the best weed eaters in 2021 are designed to hack, chop and slice away those unsightly weeds, and leave nothing but a perfectly prim and proper yard behind. If you’re sick of the weeds ruining your flowers and foliage, here are some great picks for the best weed eaters for your lawn.
Weed eaters don’t have to be expensive, and Greenworks proves it again and again with low-cost, innovative lawn care products like this string trimmer. You get massive control and a wide cutting path of 13 inches with this trimmer. The best feature is the powerful, never-quit motor of 4 amps, giving you extensive command over your lawn with powerful cutting power. You’ll also get a telescoping pole to extend your reach. This is especially helpful if you’re a taller person who needs a little more support for your lower back while cutting, which comes in handy if you also have a large yard to cover. Lightweight as can be and fitted with an automatic line feed, this 7-lb trimmer will be the only weed eater you will need for well over ten years.
Users have reported that the automatic line feed can be troublesome at times. It seems to work fine the first few times, but grass clippings and moisture can clog the line after a while, forcing you to remove the cap and feed it yourself. Fortunately, it is pretty straightforward to remove and replace that cap. The only other major complaint we found was the low amount of flap coverage. You’ll definitely need to wear protective eyewear when using this. It’s a downside, but the plus is that you know it’s powerful. Greenworks is an excellent inexpensive option and keeps your yard free of weeds like no other. It’s recommended to purchase an extra spool to keep on hand for a quick switch out. These spools are easy to rewind and have a great dual-line feed spool that is easy to work with.

Worx offers a powerful 20v operated trimmer that flips into an edger in seconds and cuts at 7600 rotations per minute. There’s no weed that you won’t be able to handle with this trimmer. Everyone wants that uniform look to their lawn, and Worx helps you get there with ten feet of line and a full 90-degree rotation. Between the handle’s contoured grip and sturdy central construction, you’ll have this for well over a decade with proper care and line replacements.
This weed eater is designed for smaller yards, otherwise, you’ll find yourself charging two packs at the same time, or having to break while your sole pack charges. That can take between three and four hours to get a full battery, and since this is the last step in securing a pristine lawn, we know you don’t want to leave the job 99% done. Weed eaters vibrate rapidly during use, especially with this level of power. That’s why Worx included a stabilizer handle to maintain your command and grip over this model, keeping everything looking exactly the way you want it to. The design is fairly lightweight, yet still made out of durable materials. We’re happy to say this is insanely portable, so you won’t feel fatigued in your shoulders during extended use. It gets the job done, but isn’t as powerful as other options, so you may find yourself going over spots again just to make sure.

Black and Decker is one of those consistent brands every homeowner is familiar with. This 40-volt trimmer offers great power to keep your yard clear, all running off of a single lithium-ion battery pack. You’ll be able to edge the side of your driveway, the sidewalk, and delicately slice weeds around your plants like a true professional landscaper. You’re also going to get a sweeper (or leaf blower) included with your purchase, that runs off the same battery pack. That battery offers an impressive two-hour runtime and works with other Black and Decker yard tools. Chop up the unsightly stems of your lawn, use the blower and get them all taken care of without having to kneel in the garden and pluck weeds manually.
The package value on this is great: leaf blower and a weed eater in one low-cost price. The downside is that they only include one battery, and both units need that battery to operate. While you won’t be operating them simultaneously, it rules out getting any help with yard work and eats up the battery a lot faster. This device is also a bit difficult to clean once you’re all finished. The automatic line feeder tends to get jammed with moist lawn trimmings and debris, so you’ll need to tend to it after every second use to ensure it doesn’t bunch up. Other than that, unmistakable power and a long-lasting construction are yours for a great price. Black and Decker are one of America’s brands that offer the longest-lasting products in their respective categories, just like this 40-volt weed eater.
Comes with a leaf blower
Powerful battery with a two-hour runtime
Blower has two speeds for more controlled cleaning around delicate flower beds
Come with only one battery for both the trimmer and the blower

What to Look for When Evaluating Weed Eaters
The power source is among one of the top things to look for. We’ve included nothing but electric weed eaters because gas models are falling out of sorts. Not only that, but there’s an entirely different cost of fuel to take into consideration. When you think about the power sources, you also need to think about battery life.
Your weed eater or weed whacker might live for ten years, but your battery might need to be replaced long before then. Look for warranties on the battery pack, but also pay note to how many volts it is in the first place. Battery solenoids will degrade over time. On average, the more voltage your weed eater has, the longer it’s going to last (though you will see diminished results over time).
Look at the overall cutting circumference and pole length. You want to cover more ground while remaining comfortable and supporting your lower lumbar. If you’re a taller person, you’ll want a telescoping pole with no less than 36” of the total length from handle to the line.
Speaking of the line, you should always opt for an automatic feed line, so you don’t have to buy a pack of individual plastic blades and swap them out all the time. Auto feeds usually hold anywhere from 10 to 25 feet worth of line at a time.
Shopping Guide for String Trimmers
Weed eaters serve a simple and fairly basic purpose. So long as it cuts weeds (and doesn’t simply bend them), then you’ll have plenty of leeways to focus on other elements. Look for weed eaters with comfortable handles, a good length, and a powerful motor to get the job done quickly without the battery running out.
The major benefit is that just about every weed eater is super affordable and can be used to help you (minorly) hack away low-hanging thin branches and leaves off of trees if it’s powerful enough. If you’re buying this for someone else, you’ll want to consider the size of their yard and how hands-on they are when it comes to landscaping. If they simply want a short lawn to comply with HOA guidelines and are not huge on having it in pristine condition, you can get away with a cheaper model.
What Is a Weed Eater?
Created by a man named George Ballas in Houston, the weed eater or string trimmer has come a long way since its inception. The weed eater is an all-encompassing trimmer designed to help manage irregular growths along a grassy surface (i.e., weeds). The idea is to make sure the robust monofilament lining can spin through the weed and trim it down to the desired level. The entire tool includes a long shaft and handles that ensure precise trimming can occur from start to finish.
It’s important to note the traditional weed eater was made to help maneuver around hard objects (i.e., decks, patios, sidewalks) without leaving a mess or missing a spot. This accurate gardening tool provides tremendous precision year-round and can work in tight corners without damaging anything along the way.
String Trimmers: What to Look For
With the best weed eater or string trimmer, it’s best to focus on specific features necessary to make the tool useful. The market is flooded with various makes and models as each one promises to be the finest thing since sliced bread. However, users have to be careful as they scour through the market, looking to filter out bad options and find something worth their time and money.
Here are some of the key qualities to look for while finding the best weed eater on the open market. This information will make it easier to find good options within minutes.
The power output refers to the amount of power generated by the weed eater as soon as it turns on. For example, some weed eaters can provide 400-1,200 watts, depending on the model. The weed eater is designed to maximize its efficiency with the help of a high-grade motor. This motor is built into the overall design and used as a launching pad to spin the actual gears. Once these gears are in action, the monofilament line whirs into action and cuts through the excess weeds.
The reason power output remains an important feature to look out for has to do with performance requirements. The more power a weed eater offers, the more a user can do while working around their yard. Sometimes, certain growths around the yard are stubborn and can create quite a mess. This is where a high-powered gardening tool can push hard enough to cut right through the weed without requiring unnecessary effort.
This is why more and more users are looking towards the overall power production before investing in the best weed eaters. It’s become one of the keystone features for modern string trimmers.
The perfect weed eater requires contemporary features to ensure its job is done properly. To make sure this is the case, manufacturers spend time assessing how “efficient” it is. This can relate to its power consumption metrics, power output (watts), durability, accuracy, or a combination of everything. Without a proper assessment of these metrics, the weed eater will not become the type of valued purchase users want in this day and age. As a result, more and more users are thinking about the overall efficiency of what’s being purchased; for example, is the weed eater able to work well in all conditions? Will it do well on uneven hills?
The efficiency of a product such as this has to be sky-high for it to become a valued investment. Otherwise, it will fall by the wayside as users don’t find it helpful in the long run. It’s important to think about this feature while buying a new string trimmer. This is the only way to feel safe about what is being bought and how it will work out.
The durability of a weed eater will hold weight when it’s time to find a high-grade model. In general, the average weed eater is made of robust gardening materials ideal for various environments, including drier conditions. This ensures whether it’s a flat terrain or a hillside, everything is manageable as soon as the trimming commences.
The build quality is also going to depend on the company’s ability to back its product (i.e., warranty).
It’s important to focus on how long the weed trimmer will last as soon as it is put together. If the weed trimmer isn’t able to hold up when the trimming begins, it will not add value to the overall collection of gardening tools. The durability also involves the line mechanism as it has to be effective for the weed eater to function. If the line isn’t coming through as it is supposed to, the entire tool goes to waste and becomes unusable over the long run.
This is why high standards are put on weed eaters to have robust line-feeding mechanisms from day one. This ensures the weed eater doesn’t fall apart as soon as the purchase is made.
The usability of a weed eater has to be taken into account while comparing options. This can include its weight, dimensions, ergonomics, and everything else associated with general usability. If the gardening tool isn’t user-friendly, it becomes a wasteful option to have up your sleeves. Some of the best string trimmers on the market offer performance, durability, and usability, all wrapped into one profound package. This is why they can appeal to the masses and work in a vast array of scenarios without causing issues.
Usability can also refer to how well a weed eater works in certain conditions. For example, if the weed eater only works well in dry conditions, it’s not going to be as easy to manage and may even get in the way of what’s being trimmed. This can become a major hassle, and that’s why it’s important to think about how usable something is before investing.
With weed eaters, there’s also a small concern with the line-feeding mechanism. In cases where it is manually setup, this can be an additional hassle the user has to deal with from time to time. All of these details need to be accounted for well in advance!
One of the underrated details to look for in a string trimmer involves pricing. Yes, the price is a part of the package and has to be kept in mind before making a decision! While it doesn’t hold the same weight as power, durability, or even usability, for many people, this does become the most important factor in the end. This has a lot to do with budgeting, and the world of string trimmers is truly diverse. This means there are small, cheap options available on the open market right alongside some of the most expensive trimmers. It’s all about finding one that is in your price range while still getting the features that matter most.
Remember, simply having a high price tag doesn’t mean a trimmer is good!
There are several cost-efficient models that do the same thing and offer better price tags. It always comes down to what you need.
The warranty is often one of the final factors associated with a weed eater. In general, a high-quality weed eater isn’t going to pose too many issues along the way, but it’s important to have a backup safety net just in case. This is where a good warranty plan goes a long way. Each weed eater comes with a set warranty coverage setup that’s provided to help protect users from a faulty purchase.
The average weed eater will come with a more traditional 1-year warranty (parts and labor). However, certain brands do go above and beyond regarding this aspect. They provide additional years based on what the user needs, as some will offer 2-3 years on top of what’s already in place.
The weight of a trimmer isn’t going to be the first thing users think about, but it does matter. In essence, trimmers are made of several different parts, and each one weighs differently. It’s not only about the overall weight but also how it’s spread out from top to bottom.
Sometimes, a lightweight trimmer can feel heavier because of weight distribution issues (i.e., it’s heavily weighted towards the head). This is why it’s best to look into how a weed eater is designed and how heavy it is in the hands.
This becomes a key point for larger yards since no one wants to lug around a heavy trimmer all day long.
Electric, Battery Operated, or Gas?
The weed eater is more than a singular design that’s sold across the planet. In fact, it’s a diverse category with numerous innovations, intricacies, and features. This includes how the motor is powered. In some cases, you will see three unique options: electric-powered, battery-operated, and gas-powered motors.
Each trimmer has its own pros and cons, which is why it’s best to weigh each one before making a decision. Before going through these pros and cons, it’s important to note, each option has merits in the right situation, and it always comes down to preference.
The electric weed eater is designed to work with a corded setup. This cord runs from the electric-powered trimmer straight into a valid outlet. The electricity is able to power the motor as long as the cord is attached to the outlet. In general, these trimmers settle in the 400-1,200 watts range in terms of power output.
Pros: Easy to Start, Ideal for Smaller Jobs, Consistent Power Generation
Cons: Limited Range, Unhelpful for Industrial Projects
These are the underlying pros and cons of an electric variation and what it can offer modern-day users. This can be a useful situation for residential owners with a small yard/lawn.
Battery-operated trimmers have entered the market and created a new category within this segment of the market. These are ideal for small-level tasks where a simple weed eater can help speed up things compared to manual alternatives. The battery can vary in size and output but is often harnessed next to the motor.
Pros: Great Range, Lightweight
Cons: Inconsistent, Restricted to Battery’s Quality
In some cases, this can be ideal for users looking for a simple, easy-to-use solution.
This is well-regarded as the most powerful and illustrious version of a weed eater and is often spotted around construction sites. Gas-powered trimmers are reliant on the use of fuel to help power the motor. As long as the fuel is present, the trimmer is fully functional and works well. There are several versions of this type of trimmer, and it is widely regarded as a great option.
Pros: Ideal for Industrial Use, Tremendous Power Output, Consistent Power Generation, Long Range
Cons: Complicated Startup, Increased Wear and Tear
While it does take time to learn how to start it up, the gas-powered weed eater remains the industry-standard among professionals because of its power output and general quality.
It’s important to note each variation brings something unique to the table, and it’s always going to depend on your needs. For some, the industry-grade qualities of a gas-powered weed eater will stand out, while others may want a residential-friendly electric-powered version instead. This is why it’s important to look through each variation and select one based on your preferences. This is how a user can pick out a solution that’s going to work well around the clock and is going to provide the type of quality users dream of. This is what a great weed eater is supposed to do!
Performance and Function
The performance of a weed eater is essential. It’s reliant on the motor successfully powering the monofilament line and efficiently spinning through the excess weeds. Along with being efficient with how it cut through weeds, everything needs to be done consistently and safely. This is why the handle is constructed to provide an ergonomic fit for the average user. With the well-balanced handle and shaft, everything is kept manageable, whether it’s cutting through large weeds or simply rounding out the corners along a winding pathway. This is where a fully functional weed eater makes a tremendous difference.
There are specific features that differentiate weed eaters from each other. Users are highly recommended to weigh each feature based on their usage requirements before making a purchase. This will depend on the type of weeds being trimmed, range requirements, weight, and more. Everything has to fit, and this begins with the right selection of features.
By choosing something viable, successful, and in line with your requirements, it’s easier to manage excess weeds without worrying about lingering issues.
Here are some of the most important weed eater features to compare when assessing a new product's merits.
The “auto-feed” trimmer refers to the automated process associated with trimming. As soon as the trimming begins, the line will continue to be fed forward to ensure it cuts through the weeds as intended. This is a unique process that eliminates manual corrects to the actual trimming during your session.
As soon as the line starts to shorten, the trimmer knows it’s time to extend its line. This keeps things straightforward for the average user. However, it’s important to note that the advancing mechanism can be halted and/or ruined by damaging the front of the trimmer (i.e., slamming it against the curb).
The fixed-line is a straightforward setup. This means it is designed to have a fixed amount that is going to be available to the user during their trimming session around the yard.
This is ideal for those who don’t want to deal with potential tangles associated with traditional line mechanisms.
The “bump feed” weed eater is a unique variation and is commonly seen in this gardening tool. In general, the bump feed mechanism uses force or bump to ensure the line continues to pop forward as soon as it runs out. For example, let’s imagine the trimming is occurring, and all of a sudden, the line comes to an end as naturally expected. In this case, a gentle bump on the front-facing head will ensure the line is pushed forward and made available again. This process continues until the overall line runs out, and there’s nothing left to push forward. In these cases, the user will have to replace the line just like they would with a battery in their remote control.
A good example of this would also be a soap dispenser. Imagine the line to be liquid soap. You will press the small button to get a small amount of soap, but there comes a point when it runs out. This is when you refill the dispenser.
The bump feed mechanism is a unique one, but it’s also popular.
String Trimmer Parts
The shaft is used to reach forward and get to those crevices around your yard without bending. Instead of manual processes where you would bend down to take out weeds, this ensures everything is done while standing. The shaft is long enough to help reach out and get to those tight spots in seconds while maintaining full control.
This is where the action takes place, and it’s the most important part of a modern weed eater.
The head is where the motor is going to be housed as well as the monofilament line. The head will ensure everything is functional and working the way it is supposed to while removing weeds. While each weed eater will have its own set of features, the head remains an integral part of how it works.
This is also the part that will come in contact with the weeds when it’s time to trim away.
While looking at the best weed eaters, customers will consider several variables, including power, durability, consistency, and usability. However, the cost associated with a new weed eater is also a valid part of the purchasing process.
In general, the average weed eater is going to come somewhere between $100-$600. However, it’s important to note this is a general estimate of how each model is priced, and some of the newer innovations can push into the $1,000+ price range. In most cases, those models are reserved for industrial situations involving construction sites or large gardening companies.
Safety is an essential component of any modern gardening tool, and it’s no different for weed eaters. In fact, several high-grade safety features are integrated into the designs of these tools. For example, the front end has a safety lock that will keep users safe if they were to press against the wrong item.
It’s important to maintain high safety standards when it comes to using a weed eater.
This is what it always comes down to with managing safety, whether it involves safety gear or how it is used.
Finding a great weed eater is all about knowing what’s required and looking for specific features in line with your requirements. Whether it’s a gas-powered, electric-powered, or battery-operated version, each weed eater brings something unique to the table. It’s important to weigh all of these options and make the best possible decision based on your needs. For some, this will include a weed eater that can cover long distances, while others want as much power as they can fit into the gardening tool. As the standards continue to rise, it’s become imperative to look into these details before making a final purchase.
