Makita 18V X2 (36V) LXT Brushless Cordless String Trimmer XRU09Z XRU09PT Review

In this review we will take a look at Makita’s 18V X2 (36V) LXT Brushless Cordless String Trimmer XRU09PT. This will be a series of Makita X2 OPE reviews starting with this string trimmer and following with the X2 Brushless Blower XBU02Z. and X2 Brushless 14″ Chainsaw XCU03PT.

Makita is no stranger to outdoor power equipment with extensive coverage in gasoline, electric and battery powered lawn tools. Battery powered OPE has been very popular in recent years and this trend will continue to grow as users move away from gas powered units to battery powered units. Earlier battery powered OPE from several years ago were low on power and runtime but with many improvements in battery capacity and brushless motors many battery powered tools can now compete head to head with gasoline tools. Makita also pioneered the use of using two battery packs together to double voltage with their X2 line which gives 18V users the opportunity to tap into 36 volt performance. Yes all Makita X2 power tools are actually 36 volt machines but while giving you the flexibility of using their popular 18V batteries. This means users can get more performance without having to switch to a different battery platform. As with all Makita X2 power tools, even though they are actually 36 volt tools, they are still part of the 18 volt family since they use 18V batteries but two at a time to achieve the extra performance.

Battery Powered OPE Pros and Cons

What’s great about battery powered OPE (from any brand) is that unlike gasoline engine equipment you don’t need to buy and refill gasoline, you don’t have to mix oil, no tune ups, no fumes, no priming and no pulling strings. Battery powered tools are ready to go at all times with a freshly charged battery and have push button starting and are generally quieter than their gasoline engine counterparts. The downsides of battery powered tools are that they are generally more expensive than gas powered tools however their have come down a lot over the years and are more affordable than ever. Replacement batteries can be expensive but they have long lifespan. When a battery runs out of juice it means the work is over even if the job is not done until the battery charges fully again unless you have extra batteries on hand.

Ethic’s Disclosure:

Makita was kind enough to provide the X2 Brushless String Trimmer XRU09, X2 Brushless Blower XBU02Z, and X2 Brushless 14″ Chainsaw XCU03PT at no cost for review. However as with all my reviews, I am not paid, sponsored, or obligated to give a positive review. This review is my opinion of the product based on my usage and knowledge and my review will reflect what I like and dislike about the said product. I will do my best to provide you with an unbiased review.

Being a 36 volt tool this Makita X2 string trimmer gets a performance bump from their regular 18V string trimmers. The added power gives this string trimmer the ability to have a 13-3/4 inch cutting swath and the power to run double 0.080″ lines. The line is easy to replace and I did have to replace the included line very quickly because they didn’t include much line so I ran out very quickly. I replaced it with Echo 0.095″ cross fire line which is what I have in stock and it worked just fine even though this string trimmer is rated for use with thinner 0.080″ line. I’ll go into more detail in the performance section of the review further below regarding the use of the thicker line. The head is a bump feed head and was very responsive and never had an issue with bump feeding new line, something I couldn’t say with the Milwaukee M18 Fuel string trimmer I recently reviewed. Attached to the head is a rear facing guard to protect the user from debris flying back at you. The guard is not the largest I’ve seen but larger than the one found on DeWALT’s 20V and Milwakee’s 18V string trimmers. which gives you added protection than those models do.

The shaft of the Makita X2 string trimmer is light and one piece which means that you won’t have to assemble the shaft when you unbox it. You still have to install the guard as is the case with most string trimmers but what was strange on this model is that you must also assemble the part of the trimmer that holds the line and bump feed system onto the head itself. It sounds complicated but isn’t and the instructions make this part very simple to install.

The top portion of the head has the BL initials which stands for brushless motor. At first I thought the motor was head mounted as the head itself is large enough you would believe there is a motor inside but I believe the motor itself is at the other end of the tool near the batteries. I believe this is true because there are vents near the battery holder section where you can clearly hear the motor revving when running and you can feel the the shaft transferring power to the head itself.

For the longest time Makita was stubborn to update their batteries with built in fuel gauges and even though all their new batteries now include fuel gauges built in, this tool has a built in double fuel gauge to check remaining battery charge for each battery which is good for those still running old packs without fuel gauges. And like all string trimmers, this one also comes equipped with a second handle to be able to hold with both hands. The second handle also requires installation before use. The second handle material is plastic with a texture on it to give you a better grip although not as comfy as a foam or rubber coated handle like it’s competition.

Makita’s competitors DeWALT and Milwaukee both have dual speeds on their string trimmers and Makita also does the same with this string trimmer but they go above and beyond with their onboard controls. This machine has a display panel with a button to power on/off the unit and select from the two speeds with visual confirmation of what speed setting you are on. With a rabbit icon for high speed and turtle icon for speed low speed. It also has a reverse mode with it’s own separate button and LED light.

I’m accustomed to string trimmers that run clockwise and when I tried this unit out of the box and found out it’s running the string counter-clockwise I was happy to learn that I could reverse the direction of the line but boy was I disappointed after trying out the reverse feature at first. I was disappointed because after selecting the reverse mode the trimmer only ran in reverse for about 2-3 seconds and cuts out automatically, even if you hold the trigger longer than that it still cut’s out. I thought this was strange and basically a useless feature, that is until I learned that the reverse mode is not to cut grass in a clockwise direction but instead this reverse feature is to loosen and remove anything that could get wound up in the cutting head like vines and such. After testing this out on a vine that got caught in the head I was immediately mind blown as it works just as advertised! Why haven’t other brands included this feature before?

While all the gizmos, features and tech would excite a gadget geek like myself, I was disappointed in the fact that the trigger is not a variable speed trigger like all the other string trimmers I’ve tried in the past. This means that a trigger press means it runs at full speed all the time, for it’s given speed setting of course. Sure it’s nice that it has two speeds to choose between full performance or battery savings but I still like to run my string trimmers at less than peak performance because you don’t need full blast all the time. I adjust the speed of my string trimmers to suit the cutting needs but I just can’t do that with this Makita model as it’s either on or off, full blast or inactive.

I also don’t understand why Makita decided to add a power on/off function into this machine. I get that it was done for safety reasons and I’m all for that but at the same time this string trimmer already has a safety button you must press before the trigger engages – just like all other cordless string trimmers I’ve tried. Basically you have two safety features and it’s more of an annoyance than anything as you wont understand why the string trimmer isn’t running when you press the trigger until you realize you have to turn it on before you use it. Luckily when you power the unit on, it stays on for several minutes so you can just pick it up and use it without having to press a power button each time you use it besides the safety button and the trigger. You can then turn it off when you’re done or it will power off on it’s own after several minutes of inactivity.

Since this tool uses two 18V batteries together to operate, and yes they must both be installed to run, it would become a hassle to have to charge two batteries separately. It would but if you buy this string trimmer as a kit it comes with a dual charger that charges both batteries at a time so you wont have to hassle with charging them separately. The dual charger is just as fast as all other Makita chargers and it charges both 5.0 ah batteries in 45 minutes which is pretty fast.

Before I move on to it’s performance I wanted to talk about pricing as pricing is equally as important as specs and features. If you guys read my recent Milwaukee M18 Fuel outdoor equipment reviews you know those were more expensive than their competition – even more than higher voltage higher performing tools. Makita follows this trend but beats Milwaukee with an even more expensive string trimmer. This Makita X2 string trimmer is priced at 249 as a baretool and if you want it as a kit it will run you nearly four bills at 394.78. Makita treats the pricing of this string trimmer as if it was another power tool and that would be fine but when you factor in the fact and reality that better spec’d and higher voltage string trimmers from other brands can be had for less than this string trimmers price as a baretool, it just doesn’t make sense from a budget standpoint. For example, you can get an Ego 56V string trimmer kit with 2.5 ah battery and charger for 199. The Ego being a higher voltage tool, you get a larger 15 inch cutting swath and it’s designed to run dual 0.095 inch line so on paper it has slightly better specs than Makita’s X2 string trimmer but for half the price. You might think to yourself: “well the Ego is cheaper because it comes with one smaller 2.5 ah battery while the Makita comes with two larger 5.0 ah batteries. That’s why the Makita is more expensive because it comes bundled with more batteries.” That might make sense but 56V batteries use more cells than 18V batteries and can actually be larger in capacity than 18V batteries. To figure this out we have to look at watt hours which is the universal way to compare batteries of any given voltage and amp hour rating. The watt hour formula is simple, you simply multiply the voltage by the amp hours to get watt hours (V x Ah = wh). So an Ego 56 volt 2.5 ah battery is 140 wh while a single Makita 18v 5.0 ah battery is 90 wh. This means that one Makita 18V 5.0 is in fact smaller than a 56V 2.5 ah battery by 50 less watt hours. But since Makita’s X2 string trimmer comes with two batteries, it makes the total combined watt hours 180 wh. Having more watt hours than it’s competition would justify a price increase yes but having only 40 wh more doesn’t justify double the price in my opinion.

Performance

I’ve tried out Makita’s original X2 circular saw before and boy was it impressive because of the added power you get from 36V tools. Just like the original X2 circular saw had better performance than 18 volt saws at the time, this Makita X2 string trimmer also has better performance than typical 18V string trimmers. In fact it’s performance is on par with the higher voltage 56V string trimmer from Ego that I reviewed before. That’s saying a lot considering this Makita X2 has less volts being a 36 volt tool so I was easily impressed by it’s top end performance. Running full speed on the Makita X2 was seemingly similar in power as the Ego 56V model when I installed the larger 0.095″ line on the Makita – more on that below.

Out of the box the Makita is fitted with 0.080 line, nothing fancy at all and it worked pretty good and strong but as soon as I replaced it with the larger Echo 0.095″ line it had a slight performance bump which made it on par with the Ego. I know the Makita is said to use thinner 0.080″ line but so far to this day it has no issues using the slightly thicker line, if anything it seems to cut better. Even the runtime remains good at a total combined runtime of 46 minutes and 37 seconds. Makita claims you can get up to 60 minutes of runtime and I got nearly that with mostly slow speed cutting and a few minutes of high speed cutting. I’ll break down the total in a bullet list below.

Going back to it’s performance, at full speed it can shred thick and tall grass in a speedy manner and even thick weeds too. This is exactly what I would expect from a high performance Makita tool.

Slow speed performance is capable and is strong enough for 70 percent of your yard maintenance needs. Sure it’s not as strong as full speed (DUH) as it’s intended for battery savings but it can take care of most of your needs. I included a video that demonstrates cutting at fast and slow speeds and even the slow speed is effective at cutting tall grass as long as it’s not thick sections of grass. If you do get into thick sections of grass the slow speed will easily slow down and if pushed further will bog down to a halt. That’s because the slow speed does not hold torque very well. Compared to the Milwaukee M18 Fuel string trimmer at slow speeds, you can easily tell the difference between the two models at slow speed. While Makita’s model sounds like it’s spinning much faster than the Milwaukee at slow speed, it doesn’t hold up torque like the Milwaukee. This means that on the slow speed on the Makita you have to go slowly as to not bog down the motor while on the other hand you don’t have to go that slow on the Milwaukee because it’s motor has plenty of torque at it’s slower speed to keep up with you. Compared to the Milwaukee M18 Fuel string trimmer at high speed, the two are about the same.

Even though I already mentioned it in the features section, I felt it necessary to repeat myself for those of you that skipped the features section and jumped straight here to the performance section. What I’m talking about is the fact that this string trimmer does not have a variable speed trigger. You either have full power or the unit is off. There is no in between speeds. Sure the 2 speed selector gives you two speed options but even then you still have full speed cutting in turtle mode or full speed cutting in rabbit mode. My point is that you don’t always need full speed in either speed setting and a variable speed trigger would allow you to get even more runtime out of your use by using only the speed necessary to cut. You simply don’t need full speed to maintain your grass on a weekly, or every other week basis. A variable speed trigger is something I use and take advantage of on all the other string trimmers I’ve tried out and was upset this model doesn’t have this feature.

Since the motor is placed near the battery holder, this string trimmer is not heavy in the front. This makes it easy to hold and wield during edging and in my experience it tires your arms less while edging than with front motor string trimmer designs. This is a feature I really appreciate as my arms don’t get tired as quick while edging.

Runtime

• 39 minutes 33 seconds – Slow speed Turtle mode
• 7 minutes 4 seconds – high speed rabbit mode
• 46 minutes 37 seconds combined total

As you can see in the breakdown above most of the runtime figure was done in the slow speed mode. Slow speed was what I needed most of the time and for the times I needed more power I switched to high speed mode for an additional 7 minutes. I’m sure I could have reached very close to 60 minutes had I ran slow speed all the time but I feel my testing shows more of a real life example. You can of course expect longer runtime if you dont go full blast and get lower runtimes if you use full blast more than I did. I also want to mention that I only count time while the tool is running and not the breaks in between use so as to give you the most accurate runtime figures possible.

Conclusion

• Very strong performance in high speed rabbit mode
• High speed performance on par with Ego’s 56V string trimmer
• 2 speeds for full power or battery savings
• reverse mode for unwinding vines that get stuck in the cutting head
• great runtime at a tested 46 minutes 37 seconds runtime
• slow speed capable for 70% of most needs
• rear mounted motor makes edging less tiring
• on board double battery fuel gauge for checking battery charge
• easy push button start, no more having to pull strings to start
• no fumes or routine maintenance associated with gas motors
• Premium/High price tag is roughly double the price of the competition
• power on/off function is unnecessary and annoying considering it already comes equipped with a safety button
• low torque in slow speed means it’s prone to bogging down in slow speed in medium thick grass
• no variable speed trigger means full speed all the time and wasted energy

Makita Cordless String Trimmer Review

When it comes to Outdoor Power Equipment (OPE), you wouldn’t expect a power tool company to be a leading OPE manufacturer. In fact, Makita is one of the leading cordless OPE companies in the marketplace. Makita was one of the first, if not the first power tool manufacturer to introduce OPE products to their line up. While they offer a gas solution, their cordless OPE technology has been leading the way forcing other companies to play catch up. So let’s check out our Makita cordless string trimmer review.

Makita Cordless String Trimmer Review – Features

When you look around at most string trimmers, they are pretty much the same. They have a variable trigger and that’s pretty much it. Well the Makita XRU09Z is a little different.

First, Makita started with a brushless motor and designed it to run off two 18V Makita batteries. Not only does this provide more run time, torque and speed, but it doesn’t force you to buy into a new battery platform.

There is an easy access button to select between two different speeds, high and low. On high, the head will have a 6,500 rpm while on low it will produce 5,000 rpm. If you equip this with two 5Ah batteries, you will get about 60 minutes of run time on low. You will also notice a push button to engage the reverse feature. The reverse feature is beneficial to help remove weeds and other items that may get stuck on the head.

MAKITA 18V X2 36V LXT Brushless String Trimmer Kit

The trimmer uses a bump and feed style which means just bump the head on the ground and the line will advance.

The direct drive motor is mounted directly on the trimmer head for improved balance and great efficiency. Also, a user can enjoy a 13-3/4″ cutting swath.

The string trimmer has a built-in feature which is a constant speed control which minimizes the reduction in rotation under load. So it will attempt to keep the same speed.

Makita Cordless String Trimmer Review – Performance

When it comes to OPE, I have to admit, I am an EGO fan mainly because they also have a mower and snow blower which means I have one battery platform. However, when it comes to string trimmers, I think this is the best cordless string trimmer on the market.

The trimmer is powerful, easy to control and has a great balance so I don’t feel like I am fighting the tool.

It really doesn’t matter if I am trimming shorter grass or thick tall grass, this unit powers through everything I have thrown at it.

Makita Cordless String Trimmer Review – Value

For me, I think this is a great value. While it’s a little more expensive than some of the other string trimmers on the market, it falls in line with string trimmers of this caliber. Considering it is one of the most powerful trimmers in its class and all the power tools you can get into with the Makita battery platform, the Makita string trimmer is a great value. The trimmer offers some great features for the price.

As of this article, it looks like The Home Depot has a better price on the bare tool compared to Amazon.

Makita Cordless String Trimmer Review – Final Thoughts

Overall this is a great string trimmer and one of my favorite trimmers. I love the two speed along with the reverse feature. The trimmer is well balanced with the two battery system. There is plenty of power and more than enough run time to perform some serious work. I am 6′ tall and I don’t feel like I have to bend over to perform string trimmer tasks. So for me, this is a must have especially for those who already own or are looking into the Makita platform.

Makita is known to have one of the best cordless OPE lineups. Th XRU09 doesn’t disappoint. With two speeds and a reverse, this is one powerful and feature packed trimmers. The 2-18V batteries mean you get a long run time and higher performance to match a 36V trimmer.

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.

• 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.

• 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

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.

• 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

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.

• 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.

• 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.

• 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.

NEW! Makita XRU09PT 18V X2 (36V) LXT Lithium‑Ion Brushless Cordless String Trimmer

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.

• 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.

• 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.

• 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

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.

• 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.”

• 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.
