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

Get the BlackDecker battery string trimmer at Amazon (with extra battery) or The Home Depot.

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

Get the DeWALT battery trimmer at Amazon, Ace Hardware, or The Home Depot.

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

Get the BlackDecker MAX battery trimmer/edger at The Home Depot or Tractor Supply Co.

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

Get the Echo battery trimmer at The Home Depot or Acme Tools.

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

Get the Worx WG170 GT battery trimmer at Amazon or Target.

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.

Voltage

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.

Noise

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.

FAQs

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.

Best Buy cordless mowers

Husqvarna Aspire LC34-P4A

Our rating: 4.9 out of 5

• Quiet
• Cuts even long grass with ease
• Battery level visible while mowing
• Small and compact for easy storage
• Part of the POWER FOR ALL cordless range

Part of the new Husqvarna Aspire cordless range, which includes a hedge trimmer, pruner and leaf blower, this 34cm mower is powered by an 18V POWER FOR ALL ALLIANCE battery and charger. These are interchangeable with tools in other leading brands such as Flymo, Gardena and Bosch so if you also invest in tools in these ranges, you’ll only need to buy the bare tool and won’t have different batteries and chargers taking up space in the shed.Great for small gardens the mower comes ready to go, there’s no assembly or handles to attach, and it folds down to a compact size when you’re finished, with a telescopic handle that folds completely flat over the body of the mower. It can then be stood up against a wall or hung up, and even comes with a handy hook. The 30l grass bag also flattens down to take up very little room and can be hung on the mower. The Aspire is light, with a carry handle so that lifting it up steps or into other areas is easy and it has an adjustable handle to suit different height users. It’s comfortable and easy to manoeuvre around the garden and has just four cutting heights to choose from, ranging from 25-65mm and changed easily with a single lever on the body of the mower. It cuts grass quietly and smoothly and has an automatic boost that increases blade speed when you’re mowing in tougher, longer areas that works well. You can hear it kick in when you push the mower into longer grass and unlike other cordless mowers that can cut out, just carries on cutting the grass. While you mow the battery charge level is always clearly visible so you know how much battery you have left and when it needs charging. It comes with a two year warranty and we awarded it a BBC Gardeners’ World Magazine Best Buy in 2023 for ease of use.

Worx 2 x 20V Battery-Powered Lawn Mower Review

Not gonna lie, if you like to let your yard get out of control for a week or two, the Worx 2 x 20V battery-powered lawn mower probably isn’t the mower for you. It struggles a bit in the power and torque department. However, if you’re the type that likes to keep your yard in good shape all the time, this mower’s runtime, noise level, and price tag all kind of rule.

Worx 2 x 20V Battery-Powered Lawn Mower Offers Quiet Operation and Budget-Friendly Price

When we tested 24 total mowers in our recent Best Gas Mower and Best Battery-Powered Mower comparison reviews, we had a wide range of expectations. One of the fun things about testing tools side by side is that sometimes we see surprises. The Worx 2 x 20V battery-powered lawn mower was one of those that performed better than we expected and improves over previous models.

Pros

• Light and nimble
• Visible battery gauge
• Excellent battery efficiency
• Nearly an hour of runtime under load
• Quietest mower in shootout at 74 dB(A)
• Best value rating out of all cordless push mowers

Not gonna lie, if you like to let your yard get out of control for a week or two, the Worx 2 x 20V battery-powered lawn mower probably isn’t the mower for you.

Battery-Powered Push Mower Ranking: 3rd Place

Performance

Want to hear about the nuts and bolts of how we tested? Check out our cordless mower shootout!

Cutting Power

Brushless and some brushed motors use electronics to adjust to changing conditions. For cordless lawn mowers, we often see them raise their blade speeds to compensate as loads increase. The Worx 2 x 20V battery-powered lawn mower ended this phase of our testing in the lower half of our push mowers for cutting power.

Starting at the beginning, we tested every mower’s blade tip speed under no load to find its baseline speed. The Worx mower banged out 2673 RPM with 151 MPH tip speeds with its 19″ blade. That puts it near the bottom, but this is just a baseline test to compare what happens when it has to start working.

With the Worx, we didn’t experience a surge in power when we applied a lighter load. In fact, the Worx dropped to 2542 RPM with 143.6 MPH tip speed. Even though it’s a net loss of speed, Worx was actually holding the 3rd fastest speed in its class at this stage.

We ramped things up after this, applying a heavier load for the next test. Here, we see most battery-powered lawn mowers start to direct more power to the blade. In the push mower group, every other mower gained some speed and power here.

The Worx, on the other hand, didn’t lose much power under a heavier load, but it didn’t ramp up either. It ended the heavy load testing with a 2540 RPM and 143.5 MPH blade tip speed, which was an ever-so-slight decrease. This was the slowest of our cordless push mowers.

The takeaway is that the Worx 2 x 20V battery-powered lawn mower does a fine job on your regular weekly cut. It begins to struggle when the grass gets overgrown, like several of the other value brands.

Cutting Area

If the power of the Worx battery-powered lawn mower left a little something to be desired, it picked up some slack in the cutting area department.

This mower runs on two 20V Worx batteries, totaling 40V max (36V nominal) of power. It also cuts a 19″ swath, which directly affects the area you can cut on one set of charged batteries.

Now that those facts are out in the open, let’s get to the juicy bits. In our testing, the Worx 2 x 20V battery-powered lawn mower ran for nearly an hour (57 minutes) on a regular maintenance load. Walking at a steady 2.5 MPH under these conditions, you can expect the Worx to mow just under 20,000 square feet or 0.46 acres.

The Worx’s battery efficiency proved to be the best of the bunch, cutting 110 square feet for every battery-watt hour.

Noise Level

We also tested all our mowers’ noise levels. Battery power is much quieter than gas power, and any direction you take in the world of electric mowing will take it easier on your ears. But we still wanted to see which was the quietest.

The Worx 2 x 20V battery-powered lawn mower was the quietest out of all 24 mowers we tested. Its 74 dB(A) lead the rest of the pack, and by a considerable margin. The next quietest mowers were the Redback 40V and the Makita 36V mowers, and they registered 77 dB(A).

We don’t like to use the term “whisper quiet” when talking about mowers – because that’s ridiculous – but the Worx battery-powered mower is about as close to that as you’re going to get.

Feature Set

Steel Deck

The Worx mower uses a steel deck in its construction. We prefer this over plastic decks for durability’s sake even though it adds some weight to a mower you’ll have to push around.

However, we still found the Worx battery-powered lawn mower to have a nimble, lightweight feel to it. It weighs in at just under 67 lbs, so taking corners is really pretty simple.

Height Adjustment and Range

The Worx battery-powered lawn mower features a single-point height adjustment. Rather than having to adjust your cutting height at each wheel like you would in a 4-point setup, you only need to make one adjustment, and boom, you’re ready to cut your grass from anywhere between 1.5″ to 4.25″.

We like single-point height adjustments for their convenience, but there’s is sometimes a downside that comes with them, and we’ve seen it here. The single point can create a flimsiness at the wheel where the adjustment is. With the Worx mower, it doesn’t feel like the wheel is going to break off or anything, but we did notice a slight dip at the wheel with the height adjustment.

Handle Positions

Curiously, the Worx battery-powered lawn mower model only has one handle position to choose from. Most of the mowers we tested included 3 positions, which are helpful for folks of different heights.

The handle has the capability of being folded over for vertical storage as well, though we found that it wasn’t particularly easy to accomplish.

Discharge Options

You’ve got all of the classic mowing options with the Worx 2x20V: mulching, bagging, and side discharge.

Value

The Worx 2 x 20V battery-powered lawn mower won the value competition in the push mower division. The kit – which includes the mower, two 5.0Ah batteries, and a charger – retails for 319. It also comes with a 3-year warranty.

But, aside from a great price, the Worx Power Share System seems to be continually growing. Getting into this mower means that you can also use the Power Share batteries with other Worx OPE tools, like their new chainsaw.

The same battery work in their 20V max home improvement tools, like the SwitchDriver. Ultimately, the Worx battery platform is a good DIY platform to get onto.

The Bottom Line

Not gonna lie, if you like to let your yard get out of control for a week or two, the Worx 2 x 20V battery-powered lawn mower probably isn’t the mower for you. It struggles a bit in the power and torque department. However, if you’re the type that likes to keep your yard in good shape all the time, this mower’s runtime, noise level, and price tag all kind of rule.

WORX 20″ 3-in-1 cordless lawnmower review

REVIEW – The last couple of springs I’ve been researching cordless electric lawnmowers because my trusty gas-powered model seemed to be on its last legs. Well, this spring it finally died. As luck would have it, I received a review offer for the WORX 20″ cordless lawnmower. Needless to say, I was very excited to see if an electric mower could perform as well as a gas-powered one.

What is it?

The WORX 20” 3-in-1 cordless electric lawn mower is a lawnmower that’s powered by 2-20V batteries instead of gas.

What’s in the box?

• Lawnmower
• Grass bag
• Mulching plug
• Side discharge attachment
• (2) 5.0 Ah 20V Power Share Batteries
• HR dual charger

Design and features

The mower came pretty much pre-assembled in the box. The only thing I had to do was extend and tighten the handle and charge the batteries.

At first glance, the WORX 3-in-1 looks like a typical lawnmower minus the gas tank and oil dipstick. The battery compartment is located where you’d normally find the gas tank.

The mower is powered by 2-20V 5.0Ah Lithium-ion batteries giving the mower 40V of cutting power.

There’s a battery life indicator located just behind the battery compartment that allows you to check the battery life with the push of a button.

Charging the batteries is done by sliding them into the included dual charger. While charging, the indicator lights flash green. When the batteries are fully charged, the lights will remain solid. Fully charging the batteries takes about 2.5 hours.

The mowers batteries are also part of WORX Power Share. This means you can share the 20V batteries with other WORX garden and lawn tools.

The mowers outer housing and wheels are made of lightweight, durable plastic. The 20″ cutting deck is made of steel and gives the mower a cutting width of 19″. Steel is not only more durable, but it’s also more mulching friendly as grass slides off steel better than plastic or aluminum.

The handle is fully collapsible for compact and easy storage.

When folded you can stand the mower up on end so it can easily be placed up against a wall. I love this because it makes it easier to store in my shed where space is at a premium.

The ergonomic handle is also padded, making it more comfortable to maneuver while cutting.

One of my favorite features is the single lever height adjustment. It allows you to quickly adjust the cutting height from 11/4” to 4” using a single lever. Much easier than my gas powered mower which required each wheel to be adjusted individually. I can’t begin to tell you what a pain that was.

The mower offers 3 different cutting methods. You can mulch, bag, or side discharge. Mulching is done by installing the included mulching plug at the back of the mower. If you choose to bag your clippings as I do, you can use the included 1-bushel bag which easily installs at the back of the mower. Lastly, you can use side discharge by installing the side discharge attachment.

Performance and use

Using the mower couldn’t be easier, just drop the batteries into the battery compartment, and you’re ready to mow. To start it, insert the plastic safety key and hold down the start button while engaging the operating bail handle. For safety, the motor stops as soon as you let go of the operating bail handle.

This mower is amazingly quiet and lightweight compared to my gas-powered model. It sounds like you’re cutting the grass with a fan. You can actually have a normal conversation with someone without having to yell over a loud engine. And its light enough that my 74-year-old mother said that even she could cut the grass using it.

Performance wise it simply blew me away. It cut my lawn every bit as good as my old gas-powered mower. It powered through tall grass and damp grass without issue. And pushing it around was like a walk in the park. Below is a video showing how easy the mower is to start and use.

I used the bagging function, and the bag was easy to take off and empty. It’s a smaller size (1 bushel) then I’m used to so I did have to empty it more often, but that wasn’t a big deal.

My lawn grows uneven, and some areas have taller grass, being able to adjust the cutting height with a single lever was easy and time-saving.

I was also remarkably impressed by the battery life. I was able to cut my front, side, and back lawn (approx. 6,000 square feet) and still had more than half of a charge left.

No gas, no oil, no maintenance… no brainer

Maybe the best thing about this mower is that it’s pretty much maintenance free. Especially compared to a gas-powered mower. No more buying gas, changing oil or replacing air filters. About the only thing you have to do is keep it clean and maintain the blade. Over time this mower will pay for itself with the money you save on gas and other maintenance.

Final thoughts

The WORX 20” cordless lawnmower is the perfect choice for small to medium size yards, and it doesn’t cost much more than a high quality gas-powered mower. I like products that make everyday tasks we dread doing easier and in the case of the WORX cordless mower, a tad bit more enjoyable. Personally, I love using this lawnmower, and I’ll never go back to gas again.

Update 7/5/20

This is my second season using the WORX 20″ cordless lawnmower, and my opinion of it hasn’t changed. The mower is great! And starting a new season without having to change oil, filters, or fill it with gas was awesome. Just pop in the batteries and start mowing. I’ve also not seen any reduction in the battery’s power or consumption over last year. If you want to make the switch from gas to electric, look no further than the WORX 20″ cordless lawnmower.
