When did DeWALT start making lawn mowers? As manufacturers pour resources into building the best battery-powered lawn mowers, shoppers have a wealth of options, and they’re not just coming from the traditional brands. In addition to time-tested lawn-mower companies like Toro, Snapper, and Craftsman, we’ve seen the relatively recent rise of newcomers like Greenworks and Ego. One interesting subset of battery-mower makers are the businesses known for their cordless hand tools. Suddenly drill and saw brands such as Milwaukee, Makita, and DeWALT are making lawn mowers and leaf blowers. It actually makes a lot of sense.

In the early 1990s, DeWALT was the first company to list a full line of contractor-grade cordless hand tools. The offering was a massive success, earning the company a loyal customer base that continues to grow. Continuing innovation is the key, as it was one of the first companies to upgrade from nickel-cadmium to high-efficiency lithium-ion batteries, and it constantly rolls out new features for improved ergonomics and overall performance. With DeWALT’s battery and motor expertise in-house, along with a strong culture of innovation, it makes sense that the company would easily move into battery-powered lawn equipment. This spring I finally got the chance to give one of its mowers a try.

I recently tested the DeWALT 2X20V MAX 21.5-inch self-propelled lawn mower for a couple of weeks on my own lawn. After trying out dozens of lawn mowers for previous articles, I approached the DeWALT project with certain expectations regarding overall mowing performance, battery runtime, user comfort, and convenience. In short, this mower did a great job for me, outperforming many of my expectations. Read on to learn more about the DeWALT cordless lawn mower and why I recommend it as a top pick for anyone who might be shopping for a cordless mower right now.

What is the DeWALT 2X20V MAX 21.5-inch self-propelled lawn mower?

The DeWALT DCMWSP244U2 is a 3-in-1 cordless electric mower with a 21.5-inch,15-gauge stamped-steel deck and a high-output brushless motor. It features a push-button start, a padded handle, and ergonomic controls. The mower is powered by two 20V 10 amp-hour (Ah) lithium-ion batteries for a total of 40 volts of power and 400 watt-hours, and it comes with two battery chargers.

The motor is equipped with auto-sensing tech that seamlessly increases torque when encountering tougher mowing conditions. A removable discharge chute, grass catcher, and integrated mulch plug allow for quick conversion to your preferred method of grass-clipping disposal. Adjustable front-wheel-drive (FWD) self-propulsion eliminates half the work of mowing, lets you choose your own pace, and works on all kinds of terrain. The deck can be adjusted to six different cutting heights from 1.5 to 4 inches. With up to 60 minutes of runtime per charge, this mower is ideal for properties up to a half acre.

How easy is the DeWALT lawn mower to assemble?

Upon its arrival, the first order of business was to assemble the mower and charge the batteries. At just under 80 pounds in the box (about 65 pounds fully assembled, with no batteries installed), it was a bit cumbersome to lug into the workshop and unpack, but assembly itself was a cinch.

I raised the lower section of the handle to the operating position, attached the upper handle to the lower handle with two large thumb screws, and clipped the power cord into the handle slot. That was it. The blade was preinstalled at the factory. Next, I plugged in the chargers and loaded the batteries to charge overnight. Total unboxing and assembly time was about 5 minutes, and charging time was about 8 hours.

How easy is the DeWALT lawn mower to use?

This mower runs on two batteries at the same time. One head-scratching moment occurred when I loaded the batteries in the mower. The battery compartment is oriented horizontally with the battery mounts beneath the top. I couldn’t actually see the contacts at the back unless I knelt and bent down to look inside. This was not a big problem, just awkward to align the batteries into the slots. But because the “fuel”-gauge feature on the XR battery happens to be on the contact end, it is concealed inside the mower housing when installed. In order to check the battery level, I would have to remove the battery. The only thing I didn’t like was the slow charging system, but an upgrade to the DeWALT DCB118 fast charger could reduce the 8-hour recharge time to just 1 hour.

Starting and controlling the DeWALT cordless mower was similar to the process for other mowers I’ve tested. A security key, inserted below the start button on the handle, unlocked the mower so that it would start. I pressed and held the start button, then pulled the wire lever down to the padded hand grip. This started the motor and blade. To start the self-propel system, I could squeeze one or both of the levers angling downward from the hand grip.

How well does the DeWALT lawn mower work?

I set up the test area in my yard, with about 10,000 square feet of lawn that included some short but steep slopes, weedy spots, and dense grass. I mowed the test plot with the DeWALT cordless mower three times, and it required just over two full battery charges each time. It mowed about 5,000 square feet per charge when adjusted to 2.5 inches high with the grass catcher in place. At 3.5 inches that extended to about 8,000 square feet. I got an additional few hundred square feet per charge by removing the bag and using the side-discharge and mulching options.

The DeWALT electric mower is a great choice for small and medium-size yards. The advertised 60-minute runtime per charge might hold up in some circumstances—see the manufacturer’s fine print—but I got more like 40 minutes, which, as noted, was good for up to about 8,000 square feet of lawn space. That should be plenty for anyone with a quarter-acre lot and most half-acre lots when the house, driveway, landscape beds, and other non-grass areas are removed from the equation.

Is the DeWALT lawn mower good quality?

In addition to the heavy-duty steel deck, a few key features pointed to higher-than-average quality and thoughtful design. For one thing, the integrated mulch plug, which is built into the bagger hatch, simply and effectively eliminates the need to keep track of an easy-to-lose part. For another, the FWD self-propel configuration drives quite well across all kinds of terrain and makes turning easier than with rear-wheel drive. Plus, the added forward weight of this configuration counterbalances the weight of the bag even when it’s full.

At the controls, everything was well laid out for easy operation, and the cushioned handle felt comfortable while I was mowing. Also, this mower is a space saver. With its fold-flat handle and vertical storage capability, it only needs about 2.5 square feet of storage floor space.

Is the DeWALT 2X20V 21.5-inch cordless brushless lawn mower worth the money?

At about 600, the DeWALT electric mower costs about twice as much as the cheapest self-propelled gas mowers. But it’s about the same price as higher-quality gas mowers and comparably equipped battery-powered mowers. So it’s at least a fair value if we stop there.

In my tests of other battery mowers at similar prices, I can say that this one offers a combination of features that others do not. DeWALT gets all of the basics right: Mowing power, operational comfort, battery life, and overall functionality are all at least as good as anything else out there. The steel deck is as stout as any I’ve tested, and better than most. The FWD self-propel system is a rarity among battery mowers, and it’s a nice touch. Altogether the base quality and thoughtful features make it a value purchase within the 600 range.

Is the DeWALT 2X20V MAX 21.5-inch self-propelled lawn mower right for you?

Battery-powered lawn mowers run quietly, keep the air cleaner, and eliminate the need to transport and store gasoline. Over the past couple of decades, battery technology and electric- motor efficiency have advanced, and have come down to approachable levels for many customers. DeWALT has leveraged its position as a leader and innovator of cordless tools to introduce this electric lawn mower.

This mower is easy and comfortable to operate on all kinds of terrain, eliminates all of the downsides of maintaining a gas engine, and delivers a nice, even cut. The price is in line with the competition, and the quality appears to be better than most. Overall, I’d say it’s a solid choice for anyone maintaining up to about 5,000 square feet of lawn, or roughly a quarter- to half-acre lot.

RYOBI 40V Mower vs. DeWALT 20V Max Mower: Which One Wins?

RYOBI and DeWALT are two renowned gardening tool manufacturers, producing unique and valuable electronic mowers for years. This sparks the question: “Which is the best, RYOBI 40V vs. DeWALT 20V mower?” Both these products are brushless and self-propelled, made of high-end materials for precise cutting.

The RYOBI 40V and DeWALT 20V mowers are 3-in-1 mowers operated on batteries. They are also priced the same with almost similar cutting deck sizes. Their running and charging time is also identical, with RYOBI having an edge of 10 minutes over its counterpart. So, are there any differences between both?

Evaluating the distinctive features of both mowers can help us decide the winner of this RYOBI 40V vs. DeWALT 20V Mower one-on-one. This guide includes a detailed comparison of these mowers and 5 interesting facts about both. So let’s dive in!

RYOBI 40V Mower vs. DeWALT 20V Max Mower: Side-By-Side Comparison

  • Brushless motor and (2) 20V MAX batteries that work simultaneously
  • 3-in-1 feature for mulching, bagging, and side discharging
  • Heavy-duty 20-inch metal deck
  • Best for properties up to 1/4 acre
  • Folding handle and lift handles for easy transport and compact storage

Please Note: As of July 19, 2023, the DeWALT 20V MAX Lawn Mower is currently unavailable on Amazon. If you are unable to locate this product elsewhere, please check back later.

RYOBI 40V vs. DeWALT 20V Max Mower: What’s the Difference?

RYOBI 40V and DeWALT 20V Max mowers are one of the most affordable options in the market. They offer exceptional performance, like a high-end mower, with reasonable charging and running time. You will find no major difference between their as well.

However, both do vary a little in terms of mulching experience. Let’s understand the most prominent between RYOBI 40V vs. DeWALT 20V Mower to see what suits your preferences the most.

Power System

The RYOBI 40V mower features an efficient brushless motor that delivers immense power like a gas-powered machine. It is a self-propelled mower that trims large-sized lawns with varying grass lengths.

This RYOBI mower comes with a load sense technology that stops the blades whenever there is too much load on the machine. As a result, it boosts efficiency and power like that of a high-end mower.

On the other hand, the DeWALT 20V max mower also comes with a brushless direct drive motor that gives users high-voltage performance. Instead of the back, the motor is located on the mower’s front wheels (similar to a gas mower). This allows you to turn the mower at different angles and control it easily.

Regardless of your yard’s length, the mower possesses enough power to cut through it on a single battery. However, if you run out of it, you’ll still have the second battery as a backup. The mower has an auto-sensing technology that offers higher revolutions per minute (RPM), allowing you to cut through different grass lengths.

The capacity and performance of RYOBI and DeWALT’s power systems are almost the same. Both have powerful engines with advanced sensors that provide efficient cutting.


What’s good for a mower if it doesn’t have a long runtime? Fortunately, both RYOBI 40V and DeWALT 20V mowers operate for a sufficient period to mow a medium to small-sized yard. The RYOBI 40V mower comes with two 40-volt batteries with 6Ah power each. The mower also has an onboard space for storing the second battery.

Many gardeners struggle with electronic mowers with batteries incapable of mowing large-sized lawns on a single charge. But that’s not the case with the RYOBI 40V mower. Its two 6Ah batteries are powerful enough to mow a yard at least 1.5 times again. You will have a runtime of up to 70 minutes on a single charge.

Meanwhile, the DeWALT 20V max mower also comes with two batteries of 20V and 10Ah of power. On a single charge, you can have a runtime of 60 minutes maximum. However, remember that the runtime depends on trimming 1⁄3 of the grass length, height adjustment, and the number of batteries you use.

Simply put, both lawn mowers have high-performing batteries, but RYOBI 40V has 10 minutes more runtime than its counterpart. So, we can call RYOBI a winner in this department.

Height Adjustment

Height adjustment is a crucial factor in electric mowers that makes or breaks your mowing efforts. A mower with improper or insufficient height adjustment won’t give you the desired cutting experience. As a result, you’ll be unsatisfied even after spending lots of time mowing the lawn.

Again, there is a tie between RYOBI 40V vs. DeWALT 20V mower regarding the height adjustment. The RYOBI 40V mower has a 10″ high-wheel design with seven settings for height adjustment. This allows you to easily input the grass height in your lawn from 1.5” to 4”.

dewalt, mower, blade, self-propelled

The best part is that the RYOBI 40V has single-point height adjustments. This means you can set the mower’s deck height single-handedly from one place instead of prying levers on the wheels.

Meanwhile, the DeWALT 20V mower comes with six options for height adjustment. You can set your lawn’s grass height from 1.5” to 4”, similar to the RYOBI mower.

However, the DeWALT mower has a dual-lever height adjustment. Many gardeners don’t find it good since the mower doesn’t display height-adjusting numbers on its rear wheels. As a result, you’ll have to measure the distance between the deck and the ground to set the mower accordingly.


You’ll find no significant difference in the blade quality and performance when comparing RYOBI 40V vs DeWALT 20V mower. Both have sharp, precise blades on the cutting deck that evenly cuts the grass and make your lawn look well-maintained.

The RYOBI mower has an inch-bigger cutting deck than DeWALT, which is good. But the difference isn’t massive enough to be noticed. Both mowers are powerful enough to give good cutting results in multiple conditions and terrains. So, whichever mower you choose, you’ll be in for a treat.


The RYOBI 40V and DeWALT 20V max mower have 3-in-1 mowing options. You can use the bagging, side discharging, or mulching functions when trimming your lawn’s grass. The mower also offers easy lift bag removal in a single motion. It allows you to quickly eliminate the content of the grass catcher bag and maximize your time and efforts.

Once you’re done mulching, you can fold the RYOBI 40V mower through its one-touch handles made of aluminum. This promotes convenient storage of the mower in different locations. This feature is also available in the DeWALT 20V.

With both mowers, you can achieve a clip-free mulching result in your lawn. Who doesn’t love an even, well-maintained yard?

Outstanding Features

Of course, there is no definite winner in this RYOBI 40V vs DeWALT 20V mower one-on-one. So, how can you know which one is better? To help you decide, we have listed some outstanding features of both mowers.

Therefore, evaluate your preferences and see what features you want the most. Here are some characteristics of the RYOBI 40V mower:

  • Telescoping, quick-release carrying handles for convenient, vertical storage
  • Hassle-free operation
  • One push-button to start the mower
  • Powerful LED headlights
  • An onboard battery compartment for the second battery
  • On-the-fly drive changes

A few distinctive features of DeWALT 20V mower include the following:

  • Strong steel deck
  • Power boost mode
  • Occupies 70% less space when stored folded than in operation
  • The auto-sensing technology boosts higher rpm to cut thick grass
  • Dual-lever height adjustment for versatile cutting
  • Low noise level


If you’re still unsure, you should look for the warranty both mowers offer to stay on the safe side. Luckily, both mowers offer a significant warranty duration. The RYOBI 40V mower comes with a limited lifetime of warranty, with a 5-year tool warranty and a 3-year for the battery and charger.

On the other hand, the DeWALT 20V mower comes with a 3-year limited warranty with a year of free service. The company also ensures 90 days of customer satisfaction. So, decide wisely, as you’ll be safe either way.

Things Included in the Box

With RYOBI 40V and DeWALT 20V mowers, you will receive all the essentials in their box for the best mowing experience. This means you don’t have to buy anything separately and start mowing as quickly as possible.

The RYOBI 40V mower has a 40V 6Ah battery, a 40V Rapid charger, and the owner’s manual. Meanwhile, the DeWALT 20V mower includes two 10Ah MAX batteries, 20V MAX 1.25 Amp charger, a safety key, and an instruction manual in the box. It also comes with a collection bag and a side discharge chute.

RYOBI 40V vs. DeWALT 20V Max Mower: 5 Must-Know Facts

We know it’s hard to decide the winner between both mowers since their performance and features are similar. However, there must be a winner, right? You can’t spend money on buying both! So, let’s go through the 5 must-know facts relevant to this RYOBI 40V vs DeWALT 20V mower one-on-one.

  • RYOBI 40V and DeWALT 20V mowers require a key to start working. You can store it in the battery compartment to not lose it anytime.
  • Both mowers come with load sensors that stop the blades when too much load is ahead. However, it could be a bummer if the technology stops the mower during thick grass mulching.
  • The battery life of RYOBI and DeWALT mowers is 70 and 60 minutes, respectively. However, DeWALT’s customer reviews show that many users complain about the mower’s runtime. It can stop working after 20 minutes!
  • RYOBI 40V and DeWALT 20V mowers come with foldable handles, so you can easily store them anywhere. The DeWALT mower takes 70% less space when folded than in operation.
  • You don’t have to use oil or gas to operate these battery-powered mowers. Instead, to start mowing, find the push-start button on your RYOBI 40V or DeWALT 20V mower.

RYOBI 40V Mower vs. DeWALT 20V Max Mower: Which One Is Better? Which One Should You Use?

Now that you know the differences between RYOBI 40V vs. DeWALT 20V mowers, you can decide which is the right choice. Remember, no “perfect-for-all” mower exists in the market, as one device may give you different results than your friend’s. That’s because a mower’s performance depends on the outside temperature, the grass length, and the user’s technique.

We can call this RYOBI 40V vs. DeWALT 20V mower comparison a tie since they are similar in most features. However, RYOBI’s battery capacity and power are better than DeWALT’s. Other than that, you’ll find identical features in both mowers.

So, we suggest you opt for RYOBI 40V as it has a slight edge over its counterpart. However, if you want to try the DeWALT 20V mower, there is nothing wrong with it. Just make sure to check the customer reviews for both brands before buying.

  • Brushless motor and (2) 20V MAX batteries that work simultaneously
  • 3-in-1 feature for mulching, bagging, and side discharging
  • Heavy-duty 20-inch metal deck
  • Best for properties up to 1/4 acre
  • Folding handle and lift handles for easy transport and compact storage

Handy outdoor power tools make quick work of tackling overgrown weeds and grass, giving the yard a tidy look and trimming hedges and shrubs. We put battery-powered trimmers through their paces on several grass or weed types to see how well they ran and cut, ultimately arriving at this list of the best battery trimmers.

For ensuring a polished look to a lawn, the best string trimmer is a great investment. These yard-care tools spin a cutting head loaded with nylon string (instead of a fixed blade) to cleanly trim the grass at the edge of a lawn or mow down weedy areas. Though gas and electric models once dominated, new and improved battery-powered versions don’t require mixing fuel or storing gasoline like gas string trimmers do, nor are they limited by the length of an extension cord, like corded electric string trimmers are.

Some battery trimmers are better suited to different-size yards, users, and budgets. So we could help consumers make the right choice, we tested some of the most popular string trimmers to find out how they perform under real-world conditions. To qualify as a top pick, a string trimmer should be durable, powerful, and easy to operate. The string line should exit the reel easily with no need for the user to constantly remove the reel cover and untangle the line.

The following battery-powered string trimmers are at the top of their class. Anyone looking to invest in a trimmer is likely to find one here to fit their landscaping needs.

How We Tested the Best Battery Trimmers

To truly test these battery-powered string trimmers, we started by assembling the tools and charging the batteries. Most trimmers arrived with the batteries about 25 percent charged right out of the box, but a full charge allowed us to gauge runtime at full power. Although some of the trimmers offer lower power settings that could extend runtime, we found that the lower settings simply made them less capable when it came to coarse weeds, so we ran them at full power for testing.

We put each trimmer through its paces in a variety of real-world scenarios: “clean” lawn grass, weedy grass, and natural areas featuring coarse, weedy seedlings and vines. To earn a spot in our lineup, the lightweight 20-volt (V) trimmers had to deliver a clean, crisp cut in both clean and weedy grass sections. In addition to trimming the grass zones, we used the 36V, 56V, and 80V models to cut through woody, viny growth in natural areas. Along with cutting power, we tested for battery runtime, maneuverability, and operator comfort and determined the best battery trimmer by category.

Our Top Picks

These reviews describe the key features of each cordless string trimmer and how the models performed in our backyard tests.

STIHL FSA 60 R 36V Battery Trimmer

It makes sense that the STIHL FSA 60 R would be a top performer in this test group. It comes from a brand with a long history of industry-leading outdoor power equipment. This string trimmer measures just over 66 inches long, weighs less than 10 pounds with the battery installed, and works for about 25 minutes per charge. The 36V 3.9 amp hours (Ah) battery charges in a little more than 2 hours.

The tough polymer material used for the motor housing and debris shield help keep the weight down. A few other standout features include a variable-speed throttle trigger, trigger interlock, battery retainer latch, EasySpool cutting head, bump guard, and hang loop. The trigger interlock and battery retainer latch prevent accidental startup. The variable trigger and EasySpool head improve operating efficiency by saving battery life and minimizing the time it takes to reload, respectively. The bump guard protects sensitive surfaces during close trimming, and the hang loop offers a convenient way to store the tool when not in use.

This is a great all-around pick for quarter- to a half-acre yards. The relatively short runtime of the STIHL FSA 60 R belies a very capable trimmer. In our tests it easily and cleanly sliced through all kinds of grass and weeds, including tough tree saplings up to about ¼ inch thick. The shorter runtime actually mattered less because the trimmer cut so well, and we moved at a faster pace than with some of the other trimmers with longer runtimes.

The other thing we noted here was the amazing level of operating comfort. The trimmer was fairly lightweight to begin with, but the weight was so well balanced—with just enough weight forward of the front handle to keep the head near ground level—that using it required significantly less effort than what was required of some of the other trimmers that weighed about the same. Also, vibration was minimal, so after trimming we had plenty of energy to keep working.

Product Specs

  • Weighs less than 10 pounds but easily powers through tough weeds
  • 25-minute runtime per charge for about 5,000 linear feet of trimming
  • Excellent balance to keep the head at ground level
  • EasySpool head, bump guard, variable-speed throttle, and accidental start protection
  • Smallish 13.8-inch cutting swath is on the small side for open spaces
  • 2-hour recharge time for battery is longer than that of some competitors

Ego ST1511T Power 15-Inch Powerload String Trimmer

Ego Power has made a name for itself in the outdoor power-equipment category by building an affordable battery-powered tool line that competes favorably against old-fashioned 2-cycle gas-powered equipment. The ST1511T 15-inch string trimmer proved to be powerful, clean, and quiet in testing. The 56V 2.5Ah lithium-ion battery delivers up to 45 minutes of runtime, with a recharging time of just 50 minutes. The bump-feed trimmer head comes preloaded with 0.095-inch trimmer line for more cutting force and less noise. Taller users will appreciate the straight shaft design, and the unit weighs in at just over 10 pounds.

In our tests, the Ego trimmer showed ample power to cut through everything in its path, including overgrown, weedy grass; privet seedlings; and honeysuckle vines. Its well-balanced design, with the heavy battery in back offset by the long, straight shaft, made it comfortable to work with and more agile than others we tested. Our only caveat: For seasonal yard cleanup or maintaining larger landscapes, the 45-minute maximum runtime may not be quite enough.

Product Specs

  • Auto-loading trimmer head reduces downtime while working
  • Adjustable telescoping straight shaft provides a custom fit for different users
  • Excellent power and runtime value at a moderate price point
  • Heavier than some with less forward weight to keep head down
  • Battery is bulkier than others, making the tool tiring to use over an extended period

Get the Ego Power battery trimmer at Amazon, Ace Hardware, or Lowe’s.

BlackDecker LST300 LBXR2020-OPE 20V String Trimmer

To give the yard a polished look without breaking the bank, consider the BlackDecker cordless string trimmer. It features a 12-inch cutting swath to cut down the corners and clean up the edges of small- to medium-size yards. An automatic feed spool means no more stopping to bump the tool when new string is needed. Two 20V lithium-ion batteries are included.

In our tests, this trimmer performed very well in weed-free grass and in weedy lawn areas. With a light weight of just 5.7 pounds, this trimmer is easy to handle without causing arm and shoulder fatigue. The short, straight shaft design is most comfortable for users under 5 feet 9 inches tall. We also liked that with a quick adjustment to the head, the trimmer becomes an edger to neaten up the grass along sidewalks and driveways. In all, we found this affordable tool a solid pick for small obstacle-free landscapes.

Product Specs

  • Pack includes 2 batteries for more runtime, less downtime
  • Automatic feed spool
  • Money- and space-saving design that both trims and edges
  • Battery recharges in just 45 minutes
  • Best for grass only; struggles with coarse, woody weeds
  • Wide debris guard doesn’t fit well into tight spaces

Makita XRU15PT1 36V LXT Brushless String Trimmer Kit

The Makita XRU15PT1 string trimmer is a premium option to keep the lawn and garden under control. It can handle large yards with enough power to tackle dense weed growth. This cordless string trimmer comes with four 18V 5.0Ah batteries so you’ll never run out of power. Shoppers can purchase this model as a kit that includes a dual battery charger and two sets of batteries, or as a “tool only” for those who already have items from the Makita 18V tool platform.

With a long, straight shaft and high-power cutting head, this 10.4-pound trimmer feels like a pro-quality tool. It was well balanced and articulate while trimming around shrubs and between obstacles. It had plenty of power to cut through tough vegetation. In our tests, it made nice clean cuts and crisp edges in the grassy areas and tore through weedy privet seedlings and honeysuckle vines without hesitation. It’s an excellent candidate to replace gas equipment for medium to large landscapes, though the price may be high for budget-minded shoppers.

Product Specs

  • Runtime is longer than charge time for ready-to-go fresh batteries
  • Includes a second set of batteries for extended work
  • Gas-like power and performance for tough trimming jobs
  • Expensive trimmer due to the high cost of batteries
  • Small debris guard allows some material close to operator
  • Stiff bump head required a hard strike to let out line

DeWALT DCST972X1 60V MAX 17-Inch String Trimmer Kit

When an established leader in pro-grade cordless hand tools enters the lawn-care category, shoppers will want to take note. The DeWALT 60V battery trimmer packs a heavy-duty brushless motor powered by a 60V 3Ah FlexVolt lithium battery that lets it tear through all kinds of tough weeds for at least 40 minutes per charge.

This attachment-capable trimmer comes equipped with a straight shaft and Rapid- loading adjustable spool. It uses.080-inch trimmer line to cut either a 15-inch or 17-inch swath. A safety switch in the grip prevents accidental starts. Users can select high or low power, depending on the project, and control the trimming RPM with a variable-speed trigger. The universal attachment feature lets owners replace the trimmer attachment with a variety of other tool heads, including an edger, hedge trimmer, pole saw, and more.

The DeWALT battery trimmer was one of the heaviest we tested, but also the most powerful. With the standard.080-inch trimmer line that came pre-spooled, this tool had no trouble cutting anything from grass to thin tree seedlings and even tough blackberry canes. In low-power mode it offered more cutting force than the high- power setting of most others we tested. In high range it beat all but the STIHL, which was about an even match in terms of pure power. To be honest, high power was too much for many of our applications, so we also tested thoroughly in low range. It ran about 40 minutes on high, and about 60 on low.

Other than the heavy weight, the only negative point we have to offer is the noise. The trimmer is loud to begin with, and when initially triggering or feathering the trigger it makes an even louder whine/whistle sound. Still, it’s a very impressive tool at a fair price for the power and runtime and a good choice for large properties or cleaning up overgrown areas.

Product Specs

  • Battery type: 60V 3Ah FlexVolt lithium ion
  • Runtime: 40 minutes
  • Weight: 12.95 pounds
  • Outstanding power for clearing overgrown weeds and brush
  • Works with.080-inch or.095-inch trimmer line for normal or heavy trimming
  • Excellent runtime of up to an hour for average grass trimming
  • Power head can run other landscaping tool attachments
  • Heavy weight of just under 13 pounds, but no shoulder strap
  • Longer battery charge time at 135 minutes
  • Noisy operation, especially when initially triggering

BlackDecker LSTE525 20V MAX String Trimmer/Edger

Weighing just 8.8 pounds, this string trimmer is easy to carry, maneuver, and control with an adjustable handle and a safety trigger switch to prevent accidental starts. The 12-inch trimming radius is suitable for keeping the lawn properly maintained without damaging fencing, decks, trees, or other common yard obstacles.

This cordless string trimmer operates with a 20V battery that can last for up to 20 minutes, and a spare battery is included. For edging, simply turn the head and use the built-in wheel to balance as the trimmer string handles the task.

When we used the tool to trim weedy lawn grass patches and edge the curb and driveway, it made nice clean cuts and tracked well to make good straight edges. The shaft and handle adjusted to comfortably fit our 6-foot user. The tool is amazingly lightweight for the amount of power it offers, but the weight is mostly balanced to the front of the handle, and having to manually counterbalance it while working fatigued our tester. Though not built for heavily weed-infested yards, it has ample power and runtime to clean up curb lines, driveway edges, and otherwise maintain a smaller landscape.

Product Specs

  • Very lightweight and easy to carry
  • Handle is customizable to fit the size of user
  • Trimmer doubles as an edger with a simple turn of the head
  • Battery provides limited runtime, although a spare is included
  • Not enough power to tackle coarse, woody weeds
  • Weighted toward the front, which may cause user fatigue

Echo DSRM-2100 eFORCE 56V 16-Inch Battery Trimmer

A wide cutting swath, extended runtime, and powerful trimming ability make the Echo DSRM-2100 eFORCE battery trimmer an excellent choice for large yards. The straight-shaft trimmer is powered by a brushless motor and 56V 2.5Ah lithium battery for up to 56 minutes of powerful performance that rivals traditional 2-cycle trimmers. It cuts a 16-inch-wide swath to get the job done efficiently.

This battery trimmer weighs in at a comfortable 9.75 pounds, making it a relatively lightweight choice at this level of capability. It features battery-saving low/high power settings for different cutting conditions, a variable-speed trigger, and a cushioned handle grip for comfort. The Speed-Feed cutting head comes preloaded with.095 trimmer line and reloads quickly without disassembly.

The Echo eForce battery trimmer is an excellent value for large-property maintenance. In our tests, the cutting power seemed to be slightly less than that of the DeWALT and STIHL trimmers, but it was still very capable. In high-power mode we trimmed for about 40 minutes. But the better-than-average power and wider swath meant that in 40 minutes with the Echo, we were able to complete work that other trimmers would need an hour to accomplish. The noise level was good, and reloading was fast and easy.

This trimmer could have scored higher with improved balance. Although it is a lightweight trimmer overall, most of the weight is in the working end. The heavy cutting head forces the operator to compensate by lifting upward on the front handle and pushing downward on the rear handle while working. We tested with the 2.5Ah battery that comes standard. Working with the available 5Ah battery (sold separately) would rebalance the trimmer to some degree while doubling runtime and increasing overall weight.

Product Specs

  • Excellent price for this combination of power and runtime
  • Wide cutting swath and power performance for large properties
  • Rapid charging system charges the battery in less than 40 minutes

Worx WG163 20V Power Share GT 3.0 String Trimmer

Owners of small yards may find this lightweight string trimmer an excellent option. It weighs just 5.5 pounds and easily converts from a trimmer to an edging tool; a built-in wheel helps balance the tool while edging. A push-button feed system gives the ability to extend the trimmer string without bumping the 12-inch trimmer head or manually pulling additional string from the trimmer. It comes with two 20V batteries and a charger, and the battery lasts for up to 20 minutes on a full charge.

This Worx string trimmer tackled our grassy areas with ease, both the weedy and weed-free zones, but it wasn’t as capable on rough areas. We were particularly impressed by the edger function, which we found comfortable and well balanced thanks to the 90-degree shaft-rotation capability. The adjustable trimmer head and upper handle let us customize the working angle, but the process of doing so proved clunky. We had to reach down and turn a rather stiff knob at the connection point between the shaft and cutting head to unlock and relock the angle for each adjustment.

Product Specs

  • Trimmer and edger in a single tool
  • Smooth push-button Command Feed spool system
  • Adjustable head tilts to 90 degrees
  • Battery provides limited runtime, although a second battery is included
  • Head-tilt adjustment is somewhat awkward and clunky
  • Relatively long 60-minute charging time for 20 minutes of runtime

Husqvarna 320iL 40V Battery String Trimmer

One limiting factor of most string trimmers is the cutting head’s direction of rotation; it matters more than one might think. The direction of rotation determines where the clippings will go, and in some situations, how the user should grip the trimmer. The Husqvarna 320iL 40V battery trimmer offers a solution, thanks to its dual-direction cutting head. At the touch of a button, we could change from clockwise to counterclockwise rotation and back, without changing grip on the handles.

This straight-shaft trimmer is powered by an efficient brushless motor and 40V 4Ah battery that drives about 45 minutes of runtime per charge. It features a Rapid-load cutting head that comes prespooled with.080 trimmer line and cuts a 16-inch swath. Low-vibration technology improves operator comfort, and the machine weighs in at just over 10 pounds with the battery.

The Husqvarna 320iL ranked near the top of the test group in terms of user comfort and quiet operation, but its power was somewhat underwhelming after the big showing from the STIHL and DeWALT trimmers. We were super impressed with the dual-direction feature. It allowed us to use the trimmer right- or left-handed, and we could safely trim curb lines from either direction without standing in the street. On high-power mode the trimmer performed lawn-trimming duty superbly, but in heavy weeds and natural areas it could not keep up with the more powerful trimmers.

Anyone not interested in going off the beaten path might still do well to consider this trimmer. Its balance is impeccable, rivaling the STIHL in comfort even though it’s a fraction of a pound heavier. And for quiet operation, this one takes the gold medal. The only real question regarding comfort and control was, why so many buttons? Its four thumb-operated buttons control on/off, high/low power, clockwise rotation, and counterclockwise rotation.

Product Specs

  • Dual-direction trimmer head leaves clippings where desired
  • Excellent balance for comfortable extended use and less fatigue
  • Among the quietest of the trimmers we tested
  • The 4 buttons and a trigger seem like too many controls
  • Even the high power is not adequate for heavy-duty trimming

Worx WG170 20V Power Share Revolution String Trimmer

While plenty of string trimmers also function as edgers, we found this model to have the best dual-function design. At the push of a button, the trimming head on the Worx WG170 Revolution trimmer converts to an edger that rolls easily along the edge of a sidewalk or driveway. The head tilts up to 90 degrees, so it is easy to reach weeds on slopes while standing comfortably.

The trimmer comes with two batteries plus a charger and three extra spools of trimmer line. The string trimmer also boasts a handy spacer guard that keeps it from bumping into plants, and the shaft adjusts to suit taller or shorter users. It cuts a 12-inch swath and operates on a 20V lithium-ion battery. We tested the tool with the 2Ah battery, but it also comes with a 4Ah battery at some retailers.

In our yard, this trimmer cut through and created a crisp edge on both weedless and weedy lawn areas. We really liked the easy adjustable feature on the trimmer head: A twist lock holds it in just the right position, up to 90 degrees, for a customized working angle for users of different heights. Also, the batteries are interchangeable with those of many other Worx 20V cordless tools.

Product Specs

  • Adjustable upper handle to accommodate users of different sizes
  • Trimmer head converts to an edger for use along sidewalks or driveways
  • Comes with 2 batteries to make up for shorter runtime
  • Requires a relatively long charging time
  • Trimmer feels underpowered for tackling coarse, heavy weeds
  • Only 20 minutes of runtime per charge

Greenworks Pro 80V 16-Inch Cordless String Trimmer

The Greenworks Pro 80V trimmer is a quality tool that adapts to a variety of other functions with attachments such as a brush cutter. (However, attachments are sold separately.) The 2Ah battery provides up to 45 minutes of runtime and recharges in just 30 minutes. The brushless electric motor is efficient and quiet, providing plenty of torque to cut through heavy weeds without the noise and smell of a gas-powered unit.

In our test areas, the Greenworks Pro trimmer was powerful enough to cut through the toughest weeds and vines with ease. The heavy battery weighs the machine down toward the rear, but the included adjustable shoulder strap makes operation more comfortable. The battery is compatible with other Greenworks 80V tools. Just don’t get too excited about the variable-speed trigger: Although it’s intended to allow a gradual increase from “off” to “high” speed, we found the range of movement between the two to be minuscule; in effect, the trimmer is either “off” or “on.”

Product Specs

  • Battery type: 80V 2Ah lithium ion
  • Runtime: 45 minutes
  • Weight: 10.6 pounds without battery
  • Trimmer has a quiet, efficient brushless motor
  • The recharging time is only 30 minutes; runtime is 45 minutes
  • Gas-like power and performance without the noise and smell
  • Slight lag time between triggering and full power
  • The trimmer’s adjustable speed feature is difficult to use
  • Weight is balanced toward the rear, but shoulder strap helps

What to Consider When Choosing a Battery Trimmer

When shopping for string trimmers, also known as weed eaters, keep in mind yard size, how often the tool will be used, and the height and strength of the primary user. The following key considerations will help in selection.

Trim Width

Trim width, also called swath width, indicates how wide a path the trimmer will cut through weeds in a single pass. Many models on the market today feature swath widths of 10 to 18 inches. The wider the width, the more power the trimmer must have, which often means the tool will be heavier because it will require a larger, more powerful battery.

Battery Type

Running a string trimmer requires a hefty dose of power. Though most of today’s trimmers run on rechargeable lithium-ion (Li-ion) batteries, a few accept nickel cadmium (NiCad) batteries. Li-ion batteries are more powerful, but NiCad batteries are less expensive (an average of 70 to 125 less). Li-ion batteries also are smaller, hold a charge longer, and provide full power throughout the discharge cycle.

NiCad batteries suffer from “memory effect,” meaning if the battery is used before it has fully charged—or if it’s recharged before its power depletes—it will “remember” the earlier charge level and won’t hold a longer charge in the future. If choosing a trimmer that has a NiCad battery, let it charge fully before use and drain completely before charging. For most users, a string trimmer with a Li-ion battery will be the best choice.

dewalt, mower, blade, self-propelled


Along with battery type, consider how much operating power the battery has, which is measured in volts. Today’s rechargeable string trimmer batteries average from 18 volts up to an average of 60 volts of power. powerful batteries at the high end often are intended for commercial use and can cost 200 or more per battery.

Some string trimmers in this category sell without a battery (or battery charger), which the user must purchase separately. This could be a cost-saving benefit for those who are adding to a same-brand, battery-compatible cordless tool collection, since the same battery will power multiple tools. However, it can be more convenient to purchase a kit with multiple batteries to have one on the charger while the other is in use.

Feed Type

The “feed” of a string trimmer indicates how the trimmer head releases additional trimmer line as it becomes frayed and broken during use. The standby is a bump feed where the user bumps the bottom of the trimmer (the area where the spool attaches) on the ground to release a few inches of fresh line.

Some newer models feature an auto-feed sensor that gauges the length of the strings and releases more when needed. Still others have a push button to release more line. Auto and button feeds eliminate the need to bump the spool, which can reduce the risk of damage if bumped too hard, but many commercial-type trimmers still use bump feed because it’s quick and easy.

Curved vs. Straight Shaft

Some string trimmers feature a straight shaft that runs from the handle to the cutting head, while other models feature a distinct curve in the lower shaft about two-thirds of the way down. Some users find curved-shaft trimmers to be easier to operate since the spool end already rests at a handy angle for weed whacking.

Straight-shaft trimmers often accommodate interchangeable tools, such as a tree trimmer head, which can be swapped out depending on the task at hand. In general, straight-shaft trimmers work better for users at least 6 feet tall, while shorter users will appreciate curved-shaft trimmers.


Battery-powered string trimmers have a distinct advantage over gas-powered trimmers when it comes to noise pollution. Gas-powered trimmers are moderately loud, emitting an average of 90 decibels (about as loud as a motorcycle passing by from 25 feet away). By contrast, a cordless string trimmer emits approximately 77 decibels, which is comparable to casual conversation.


Those who are still unsure about how to use a battery string trimmer may find the following answers to common questions about these tools helpful.

Q. Can a string trimmer cut weeds?

A string trimmer is used to cut and control weed growth around the home and garden. However, light-duty trimmers may have issues with very dense weed growth.

Q. Can you use a string trimmer to cut grass?

A string trimmer can be used to cut grass, though you need to be careful not to cut the grass too short while trying to keep the trimmer balanced. It isn’t the easiest way to cut the grass, but it is possible.

Q. Can you edge with a string trimmer?

Yes, a string trimmer can be used for edging the garden, driveway, walkway, or sidewalk. If you have a large yard, it may be better to invest in a separate edging tool.

Q. How many volts should be in a trimmer?

String trimmer batteries average from 18 volts up to 80 volts. Typically, the higher the voltage, the longer the battery life.

Q. How do you edge a lawn with a string trimmer?

Hold the string trimmer perpendicular to the lawn to keep the cut even. Position the head about 4 inches off the soil so the string has space to rotate. The string should rotate and cut through the grass and dirt. As you move along the desired borders, keep the head balanced and even. Clean up the cut grass and dirt to finish the job.
