At the of the guide, you would easily make an informed decision about which would be great for you.

What to Consider

The cutting swath will determine just how good it is for handling the different growth in your garden or lawn. We suggest that you go for a model with more cutting swath so that you do not end up struggling to handle the different applications you might have in mind.

You also have to consider the battery capacity. Having a model that has more battery capacity means that you get more runtime while at the same time have more power to cut the tough growths in the garden.

Look at the product specification area to see what kind of battery system you get with the unit.

The feeding type will vary from one unit to another. It can be an automatic or bump type. Whichever method, look at how easy it is to feed the line. Some models can have the bump style that is still easy to feed the line into the unit.

The overall period of warranty should give you peace of mind that you are buying a great tool. There are models that can have warranties of up to three years. This will give you the confidence in the tool knowing that it can last for longer.

Let’s Compare

DeWALT DCST925M1 String Trimmer

It is hard to go wrong with a DeWALT string trimmer. That is exactly what you experience with the DeWALT DCST925M1 string trimmer. There is a lot more to experience other than it is from a DeWALT brand. Let us check out its features below.

The Cutting Capacity

The cutting capacity is a crucial consideration for many buyers. Well, this one has a cutting swath of 13 inches using a 0.080” line. As such, it is going to be a nice option for many to get for handling the various applications.

As for the speed, we are looking at a model that can go up to a maximum speed of 6,300 RPM. For many, this kind of speed is good for leaving you with clean cuts.

Still, as part of the speed, the unit comes with a variable trigger with the option of running the unit at either low or high speed. The low speed can be used when you want to use it for extended periods. The high speed is for more power delivery.

The battery system of this unit is all about more power delivery than the models before it. It uses the 20V MAX 4.0Ah lithium-ion battery. This type of battery is good for handling any trimming applications you might have to handle in mind.

The unit has the best gear drive transmission design from DeWALT. The result is that the gear system will allow for the power to get down for easier and faster cutting of the overgrowth.

The model weighs 7.4lbs., which is good enough for many to use for long sessions. It might not be the most lightweight among the string trimmers, but it is still lightweight enough for many users. They would use it for hours without necessarily feeling it is too heavy for them.

Being lightweight is also a nice addition to the ergonomic and balanced design. This helps you to move the unit freely while working on a project.

DeWALT DCST920P1 Brushless Trimmer

If you are willing to spend more, then the DeWALT DCST920P1 unit can be a nice option to consider too. It has more battery capacity and performance. Below are features to expect from this brushless trimmer.

Patented Gear Drive Design

The patented gear drive design is a nice addition to the common transmissions you get with other units. Being a new design, we expect it to be better. Well, DeWALT does not disappoint as this gear system allows for powering through any growth with ease.

As for the weight, the model weighs 8.5 pounds. Some might find it not being the most lightweight model they have always wanted, but it is still good to keep you from feeling fatigued.

Still, the overall design will help you to easily control and minimize the stress on the arms. As such, you can get more people going for it right now.

You should enjoy the variable speed option that you get with the model. There are two-speed options for you to use. They include 0 to 4,600 RPM and 0 to 6,000 RPM. Depending on the application, it is easy to choose which speed to use.

Another top consideration for many users would be the type of line feeding you get with a model. Well, this one offers the bump style of feeding.

The best part is that it also comes with the QuickLoad spool system that allows for fast and easy re-spooling of the line.

High-Efficiency Motor

The unit features a brushless motor as part of its construction. The result is that it will live up to your durability needs. This is because a brushless motor does not need a lot of maintenance compared to brushed motors.

Also, the brushless motors are good for maximizing the runtime. This is because it does not consume a lot of power so it should be good for your battery.

The 5.0Ah lithium battery easily stands out as a nice option for you to get right now. It will always help you to cover a lot more without necessarily worrying that the charge will deplete faster. Since it uses the 20V MAX system, you will find that it is compatible with many batteries in the market.

Most Common DeWALT 20V Trimmer Problems

DeWALT 20V string trimmer is a valuable piece of equipment for cutting grass in tight spaces that a lawnmower can’t reach. The grassy areas close to plants and fences fall into this category. You can also use the tool for more efficient edge cleanup.

What are the major DeWALT 20v trimmer problems? A DeWALT 20 V battery-powered trimmer’s initial big issue is the time it takes to charge. Due to their short battery life, these trimmers require multiple charges if you have a large yard.

We’ve all used different machines. like the DeWALT 20 V trimmer, throughout our time as mower enthusiasts. Up to this point, it’s performed admirably as a string trimmer.

Despite this, it is still just a machine. Consequently, modern society has to deal with several challenges in this area.

The Most Common DeWALT 20v Trimmer Problems

Despite DeWALT’s widespread reputation as a reliable source for power tools like string trimmers, some customers have complained about poor quality and reliability. These customers have reported all sorts of issues with the DeWALT string trimmer.

Like many others before them, anyone with string trimmer problems has found the appropriate resource for support. This post will provide a comprehensive set of solutions guaranteed to fix the issue.

Engine Won’t Start

If you’re using a DeWALT string trimmer, this is one of the most frequent problems you’ll experience. Most affected users report that their string trimmer is no longer powering on. They cannot put the device to any use because it will not power up.

Fortunately, there are a couple of things you can double-check. The first thing you should do is make sure the string trimmer’s batteries are fully charged. Dead batteries may be to blame if your trimmer won’t turn on. You can double-check this using a different tool or attempting a different set of batteries.

The battery charger is another component that should be examined. It could be failing to charge the batteries, preventing the trimmer from receiving any power. If you check each one and find that it is functioning normally, you may want to consider getting some professional help.

Uneven Cut

As you may have noted, the DeWALT 20 V string trimmer is a portable tool. Moving it requires you to hold it in place on your lawn. Therefore, if you want an even finish on your property, you must keep your hand steady.

It’s also challenging to handle for long periods, as the machine weighs roughly 8.5 lbs. Like with other mowers, the outcome is not great because of the shaky grip. Also, the burden of the head makes it challenging to move around.

Engine Shutting down when in use

Having your device turn off unexpectedly while using it is pretty frustrating. If you are having the same trouble with the string trimmer. I recommend checking the batteries. To put it simply, they are the trimmer’s lifeblood.

Debris near the spool may be the culprit, so ensure you inspect the area. Additionally, ensure the string trimmer’s safety guard is still in place. If that’s the case, reattach the trimmer’s safety shield.

Ultimately, you can try to shorten the maximum length of the trimmer to 13 inches (or 330 mm).

Engine Runs Slowly

The inability to reach full speed is another prevalent problem with these string trimmers. Instead, they move at such a snail’s pace that they can’t get the job done of thoroughly cutting or trimming the grass.

Our first piece of advice is to pull the variable speed trigger. The trigger’s level determines how quickly the unit will move.

You should make sure the spool can spin freely without stopping. You can give cleaning it a shot, but be careful not to break anything or hurt yourself.

If the cutting lines are more than 4-13/16″ (122 MM) off the spool, they are too long and need to be shortened. If this is the case, you’ll need to make your cuts such that the material brushes the edge of the trimmer.

Exhaust Problems

When in use, the DeWALT 20V trimmer spins at a Rapid rate. Due to its high operating speed, the engine quickly becomes hot. DeWALT’s engineers have added extra safeguards to ensure the tool doesn’t get too hot to use.

DeWALT’s 20V gardening tool needs a reliable exhaust system so that it can vent hot air out and the device can cool down.

Long-term engine health can be protected from overheating with proper maintenance. If you use a DeWALT 20V trimmer and notice that the air intake is getting clogged with debris, you should clear the vents.

Not Enough Batteries

If you want the best tool for helping you keep your garden or horticultural space in tip-top shape, go no further than the DeWALT 20V string trimmer. It doesn’t have a cable; instead, it runs on batteries.

This device’s brushless motor consumes less electricity than conventional motors. A battery capacity of 5 Ah is ideal for operating this device.

If the batteries in your string trimmer wear out. the tool will no longer be able to function effectively. We recommend that our readers always have a fully charged spare pair of batteries on hand while using the DeWALT 20V trimmer.

Insufficient Intake of Air

The air filter filters the environment air before being sucked into the powerful DeWALT 20V trimmer.

When the operator uses the tool to cut the grass or weeds. the surrounding area will likely become oppressively humid. An air filter should be installed to filter the air and remove any debris that could cause damage to the equipment.

Dust, debris, and dirt from the surrounding environment might clog the air filter if it doesn’t regularly undergo maintenance. Consider what would happen if you never changed the air filter. It can cause the DeWALT 20V string trimmer to behave erratically and roughly.

The air filter isn’t expensive. but it needs to be changed often to keep your trimmer running smoothly.

Grease build-up on Gears

The tools and machinery you keep in your shed are designed to last. With its sturdy construction and efficient operation, the DeWALT 20V trimmer is a valuable tool. The operator should occasionally lubricate the gears and other moving parts with oil to ensure their smooth operation.

As we’ve mentioned before, keeping your DeWALT 20V trimmer clean is essential to its continued smooth operation.

If you don’t clean the gears, grease will attract dirt and dus t, which will build up until the trimmer can’t move its loads efficiently.

If you want to keep the grass trimmer’s gears clean and free of build-up. it’s essential to take your time cleaning them and applying oil.

DeWALT 20v Trimmer Problems: are they a deal breaker?

The DeWALT 20V string trimmer is excellent for maintaining a tidy garden and neat surrounding regions. A great string trimmer requires little work yet produces excellent results in horticulture.

Customers rave about the DeWALT 20V trimmer’s performance, although some have reported issues with the tool. We’ve compiled a list of complaints about this product and provide solutions on this page.

Following these simple tricks and recommendations, using a DeWALT string trimmer won’t be as difficult. Have fun while gardening, and good luck!

Brushless String Trimmer Shootout! DeWALT, Toro, STIHL, Troy-Bilt

This article is a review of four of the best cordless string trimmers available right now. The Toro Power Plex, STIHL FSA 90 R, Troy-Bilt C.O.R.E., DeWALT Flex-Volt. I also talk about the new EGO carbon fiber shaft trimmer.

I’ll admit it – I’m one of the people who would love to see all small lawn garden gas engines disappear. In particular the cheap homeowner string trimmers, blowers, hedge trimmers and even chainsaws. I’ve owned way to many of them over the years and they have always been notoriously hard to start, noisy and don’t last long. In the last 15 years even if you do find one that is better than most – the engines have been regulated to the point where they have no power for all but basic tasks. Because of that, I’ve spent the last five years watching the cordless, battery-powered string trimmer market come of age. As homeowners, we are finally getting quality trimmers, blowers, hedge trimmers and other equipment for our normal suburban lawns that will do the job better than the small gas engines. In my opinion, there are now a few on the market that will tackle any of your tasks and last for years.

Right to left: STIHL, Toro, Troy-Bilt, DeWALT, Husqvarna Gas for comparison.

I purchased these brushless trimmers myself. I’m not sponsored by any of the brands so it helps me to stay completely objective in my reviews.

There are well over 75 different cordless string trimmers on the market right now and after reading all the specifications and reviews I purchased 4 models for this article. The models I purchased are the Toro Power Plex, STIHL FSA 90 R, Troy-Bilt C.O.R.E., DeWALT Flex-Volt. All of these are designed to replace your gas trimmer. All use the latest high tech brushless motors to give you the most power and battery efficiency. I’ll keep this article simple and only go over what I like and don’t like about these trimmers.

Most of the links in this article will take you to Amazon. My readers and I have been having just the best luck buying cordless string trimmers from Amazon. If a model is available directly from Amazon or a reputable seller on Amazon I will offer you a buy link. Amazon literally is the best place to buy anything online. The delivery is swift, and if there are any issues with the shipping or the item Amazon takes care of it immediately. Buy at Amazon

By the way, Just assume that if I send you to a website to “read more and buy” I’ll make a small commission from the sale. (That’s how I make the money to operate this site)

The Best Trimmer Line? I like this trimmer line for all string trimmers:

If you don’t have a lot of experience using string trimmers or you have weak wrists I suggest buying the round line. I use round line myself.

The trimmer line below is edged and cuts the best but the edges can “catch” and cause your trimmer to stray into areas you don’t want to be trimmed.

Number One – Toro PowerPlex Brushless String Trimmer Review

Buy Here: Toro PowerPlex 51482 Brushless 40V Lithium-Ion 14″ Cordless String Trimmer, 2.5 Ah Battery Charger Included

Of the 4 trimmers, I bought the Toro is the one I grab the most often.

Toro has been fairly slow to come out with a competitive cordless string trimmer. Why? Because they never jump on the latest trend without spending hundreds of hours researching and testing their prototypes. You can be assured that the item they offer is good, reliable and ready to last you a long, long time.

The Toro 14 inch brushless is different from the rest. It’s designed for a suburban homeowner who needs a well built, easy to operate, lightweight trimmer. Many homeowners just want a good trimmer that is very easy to use, is lightweight, trims their lawn well and can cut down the occasional 3-foot weed they missed. With the battery, it is less than 9 lbs. They don’t need a 14 lb monster trimmer to go out in the back 40 and knock down an acre of horseweeds.

What I really like about the Toro

• Extremely efficient brushless motor. The speed is controlled with a trigger just like your older gas powered trimmer so you can trim around delicate areas. This trimmer is very quiet.
• Lighter than all the other trimmers I handled. The quick adjust handle will let both short and tall people use this trimmer any time. You will not need to use a carry strap for extended use. It is balanced very well with just enough weight in the head so it’s very easy to trim accurately around delicate plants and landscaping.
• Heavy duty dual line head for efficient cutting. It uses the standard.080 line and can accept the rounded, twisted and edged varieties. You can wind your own or buy pre-wound spools.
• Excellent quality. Toro has engineered every part of this trimmer to last.
• Foldable for transport in your car trunk. The only straight shaft trimmer on the market that easily folds up.
• At least 45 minutes run time. I can trim my entire one acre landscaped yard twice on one charge. Included T90 battery charges in just an hour.
• This trimmer is part of a system that includes a 480 CFM 150 MPH leaf blower, 24-inch hedge trimmer, 13-inch single line trimmer, 14-inch chainsaw, and double capacity T180 battery.

DeWALT proves me wrong on cordless trimmers/edgers

The Elephant In The Room: Toro’s Battery Size.

From Justin: I am concerned about battery life which is my only hesitation the Toro’s low watt-hour T90 battery.

My Answer: The Toro is very efficient and I can get 40 minutes or more of run time out of the T90 battery. Remember you don’t need to leave it running like you do with a gas model when you walk from one area to the next to trim. It also trims very well at half-throttle so the battery can last even longer.

If it takes you longer than that to trim just slap the battery on the charger and have a cup of coffee. You don’t have to charge the lithium battery fully each time you use it. Plus when you are done you can leave the battery on the charger. It won’t hurt the battery at all.

Justin: You know, I hadn’t considered that the unit is not running at all times. You have completely changed my view on what 40 minutes of battery life actually means!

• So, the T90 battery is great for a string trimmer and hedge trimmer but the T180 (5 AH) is a better choice for the leaf blower and chainsaw. I would like to see a purchase option for the blower and chainsaw with the T180 Battery.

Batteries: DeWALT FlexVolt, Troy-Bilt 40v, Toro Power Plex, STIHL AP300

Number Two – STIHL FSA 90 R Brushless String Trimmer Review

STIHL makes four cordless string trimmers with removable batteries. In addition, they make two separate battery series. The AK series is designed for homeowners. The AP series is designed for large acreages and commercial operators. The FSA 90 R I choose for this test is the top-of-the-line commercial version. I purchased it with the AP300 battery/charger.

Why? Because I needed one “standard” to judge all the others by. In addition, I’ve used the commercial gas series STIHL trimmers for years and think I the trimmer head they use is one of the best on the market.

What I really like about the STIHL

• With the AP100 battery, it weighs just a few ounces more than the Toro PowerPlex.
• Has many battery options ranging from a 100 WH for homeowners to a huge backpack battery for all-day commercial use.
• Uses the same commercial trimmer head the gas engine models use. It will last the life of the trimmer and then some.
• It has a speed limiter dial on the handle. You can dial down the top speed and it will trim your weekly work well and the battery will last all day. Most reviewers don’t get the dial is for economy and/or speed control around delicate plants.
• Tremendous cutting power. Even when cutting 8-foot prairie grass I could not get this trimmer to slow down. It also does an excellent job of not wrapping around the head when cutting tall grass.
• This trimmer is part of a system that includes other trimmers, chainsaws, blowers, hedge trimmers and steel-deck walk-behind mowers.

No, this is not a “quick load” head. You will have to read the instructions to load new line on it the first time. Take your time to learn how to load it and it will be easy after that. BUT! It always works and never acts up. Remember, this head is their commercial head and even in the worst conditions and abuse, it will last.

Here is a video showing you how to load the head. FYI – you don’t need a screwdriver to push in the buttons. The buttons are designed for your thumbs.

What I don’t like about the STIHL

• Most expensive cordless trimmer on the market.
• You must go to a local dealer to purchase.
• There is no suggested pricing online so you don’t know if you are getting a good deal from your local store. STIHL MAKES you shop different dealers to make sure you are getting a fair price.

Intermission: Is a brushless string trimmer right for you?

Before I discuss the remaining trimmers I want to say: The best brushless string trimmer right now for most people is the Toro Power Plex and the best brushless string trimmer on the market is the STIHL FSA 90 R but it may not be the best trimmer for you.

If you just need a trimmer for weekly mowing tasks I actually suggest getting a trimmer to match your cordless drill batteries. For about 100-150 you can get a bare tool DeWALT 20 volt, Ryobi 18 volt, or Milwaukee 18 volt. These are all quality, brushless motor string trimmers and they will do the job well for you. Don’t fall for the hype of having to have a separate high voltage battery for your yard tools.

Number Three – EGO Power Carbon Fiber Shaft Trimmer

What about EGO Power ? I’m going to go through the EGO in the video below. EGO gave everyone on YouTube with a thousand subscribers or more a free one over the last three years so the older models have been covered to death. For 2018 they have introduced two completely new lines of trimmers …again… and I just finished this video on the new EGO carbon fiber shaft trimmer.

The EGO is not my first choice for most homeowners but if you want a complete system – walk-behind, trimmer, blower, chainsaw, edger, etc they are worth comparing to the other models in this article. EGO Power at The Home Depot

Number Four – DeWALT Flex-Volt Brushless String Trimmer Review

DeWALT currently makes 3 string trimmers. a 20-volt MAX, 40 volt commercial and 60 volt. I’ve used all three and I decided the 60 volt Flex-Volt was the one I should buy for this test.

What I really like about the DeWALT Flex-Volt

• I like that it uses the same batteries as the FlexVolt tools. If you already have the batteries you can save 100 and just buy the bare tool.
• It has the most power of the three DeWALT string trimmers. power than the Toro PowerPlex and a little less power than the STIHL FSA 90 R. It has plenty of power to cut down tall weeds.
• Conventional – dual line head.
• It’s balanced well. It’s about 4 lbs heavier than the Toro PowerPlex but for most people, you can trim your entire lawn without it getting too tiring to use.
• The head accepts both.080 and.095
• This trimmer is part of a system that uses the same Flex-Volt battery for both hand tools and lawn tools. At this time it does NOT include a walk-behind mower.

What I don’t like about the DeWALT Flex-Volt

• It’s noisy. DeWALT has chosen to use a brushless motor and a gear reducer. The gears are noisy compared to the other brushless trimmers I tested here.
• The trimmer head works very well but winding new line takes practice. Sticking the line through the holes in the housing can be a pain. I wish it had the drop in slots like the STIHL.
• All the other brands use a sealed aluminum housing for the motor on the trimmer head. The aluminum dissipates the heat during use, The aluminum design is very rugged and you can use it under any conditions. For some unknown reason, DeWALT decided to use a steel housing and use air vents to cool the motor. Yes, that’s how they make all their hand tools but what made them think that was a good idea on a string trimmer! What. I know DeWALT uses vents and fans on all their hand tools to cool the motor. But this really doesn’t make sense on a string trimmer. You have to clean air vents on the trimmer head every time you use it and DeWALT also states “Do Not Get the Head Wet!”

Number Five – Troy-Bilt C.O.R.E Brushless String Trimmer Review

I am a big fan of the CORE Technology electric motor so when MTD purchased the company a few years ago I was hoping they would take it to the next level and design a complete line of cordless tools around the motor.

C.O.R.E. is an actual technology not just some advertising lingo that sounds good.

• The battery life is phenomenal. The CORE uses load sensing electronics to keep the trimmer running at an optimum speed. When you are trimming weekly growth it uses very little power but get into the high weeds and it automatically senses the extra load and supplies more current to the motor.
• It’s heavier than the Toro PowerPlex or STIHL FAS 90 R, but comes with a built-in snap ring for a harness.
• The trimmer head is built very strong. I’d guess that it’s the toughest residential head on the market. It is an easy load head (more on that later)
• This trimmer is part of a system that includes a self-propelled steel deck mower, blower, and hedge trimmer.
• I personally didn’t get along with the trimmer head. It’s a quick load head but for some reason, I could not get it wound correctly and I always ended up with a bird’s nest. I don’t see any reviews with the same problem though – maybe it’s just me.
• With great power – comes greater weight. This trimmer was the heaviest of the bunch but it also has the longest run times and the battery can also power a self-propelled walk-behind motor. No need to buy additional higher capacity batteries for the mower.
• It’s balanced like a gas trimmer. There is more weight on the rear than on the head. so when you are walking from one landscape bed to another using one hand the head pops up. Although it’s like your gas trimmer it’s not as efficient because you have to push the head down each time you start to use it. Is that really a problem? Maybe it’s just me….

The trimmer head and I didn’t always get along

Load sensing panel with the boost button

Summary

As expected the entire cordless trimmer market is a mess and full of advertising hype and misinformation. Many of the reviewers don’t understand the terminology of battery tech so they are mistakenly using max voltage or amps as their deciding factor in which models to promote. It’s not volts or amps – it’s Watt-Hours.

Other reviewers are sponsored by a brand or getting free stuff to review and that is skewing the results. Here are two articles that explain what is important to know about the batteries.

Buying guide for best DeWALT weed eaters

A well-manicured lawn requires proper effort, planning, and the right tools for a job. Grass, roots, leaves, and flowers need to be tended to regularly so that they’re all growing — or not growing, in some cases — in their respective spaces.

A weed eater is a useful tool that can serve you throughout the season. Also known as a string trimmer, a weed eater eliminates weeds and helps you maintain boundaries throughout your lawn. You can use a weed eater to keep grass off your driveway, path, or sidewalk, as well as to prevent unwanted plants from encroaching on your beds and gardens.

DeWALT is one of the most popular names in home tools and hardware, and the company produces a selection of outdoor equipment, including weed eaters, that cater to most homeowner lifestyles. The products are light, efficient, and trustworthy. Our guide will take you through DeWALT’s weed eater offerings, explain how they differ from competitors, and show you why a DeWALT weed eater could be the best choice for you.

Register your product online with DeWALT upon purchase. You’ll be able to access the warranty and browse any necessary guides or instructions.

Key considerations

Weed eaters vs. string trimmers

Terminology matters when shopping for lawn care equipment because often, several names exist for the same or similar items. What’s more, not everyone uses the same term for the same thing.

Concerning DeWALT, and indeed most companies, the terms “weed eater” and “string trimmer” are used interchangeably. An alternative to the string trimmer is the bladed trimmer, which offers more power and durability but also requires more power and a higher degree of maintenance and energy to use. Bladed trimmers can also serve as edgers, which are designed to create boundaries. Some weed eaters can do this job, too, though they don’t have the same power or effectiveness on tough jobs.

Power

Weed eaters may be gas-powered, electric, or manual. DeWALT, however, only makes electric weed eaters powered by battery. These are better for the environment and create less air and noise pollution than gas-powered weed eaters. They are lighter, smaller, and easier to store and transport. However, they aren’t ideal for large plots and may struggle with tough, dense weeds.

Notably, you will need to invest in a DeWALT battery and charger. The lithium ion battery can be used across various DeWALT products, provided the charge is the same.

Usage

Weed eaters are designed to help maintain boundaries in certain areas of your lawn and garden. However, they are not necessarily designed to manufacture those boundaries. That’s the job of an edger, which can dig several inches into the soil to create a barrier. While some companies offer dual trimmer-edger tools, DeWALT currently does not. That said, there are some hacks you can use, which we touch on elsewhere in this buying guide.

DeWALT’s weed eaters are two-handed pieces of equipment that are best used to cut back weeds and grass from flower beds, sidewalks, and driveways. They are useful in areas where a bulky lawn mower may not be able to reach, such as around mailboxes and under bushes.

Spool

Weed eaters trim grass with a nylon string that is housed in a spool at the base of the device. You can toggle how much of the string is exposed in order to adjust how much grass is cut. The nylon string will wear down over time and require a replacement spool. DeWALT offers a Quickload replacement spool designed for fast, easy use. DeWALT spools also extend, or “bump” the feed line as necessary when in use.

Cutting swath

Most DeWALT string trimmers feature a cutting swath of 12 to 15 inches. While that may not seem like a big range, every inch makes a difference when it comes to tending your lawn. Shorter lengths offer a bit more control and precision. Longer lengths may offer more protection and distance from encroaching weeds.

Weight

One of the perks of DeWALT weed eaters is portability. Generally, these tools weigh under 10 pounds and are easy to hold and wield with two hands. Keep in mind that bigger jobs will require more energy and creating precision boundaries will call for steady handling of the machine.

Shaft

While some companies offer a choice of a straight or curved shaft, DeWALT’s weed eaters only feature a straight shaft. Straight shafts generally offer more flexibility on the job and the ability to access hard-to-reach places. Curved shafts generally offer more precision and control, but they may have difficulty accessing hard-to-reach places.

Battery power is an important consideration when evaluating DeWALT weed eaters. We find out how long it takes to fully charge batteries as well as how long the machines can work before batteries must be recharged.

When shortlisting products, we factor in the weight of the weed eater to determine how easy it is to maneuver while trimming.

The ease with which the nylon string feeds off the spool determines how effective each DeWALT weed eater is at trimming. We explore this performance in our research.

We consider whether a battery and charger are included with purchase. Some DeWALT models include both, whereas others require the consumer to buy them separately.

Battery voltage is a key factor we keep in mind when recommending DeWALT weed eaters. These tools are available in 20-, 40-, and 60-volt models. The higher the voltage, the more powerful the weed eater.

We look at the speed settings offered by the tool. Some DeWALT models have various speeds for different trimming needs

DeWALT offers 60-volt batteries that are backward compatible and can work on devices using 20-volt batteries. This is especially useful if you need a powerful weed eater but own other DeWALT items that only require 20-volt batteries.

Bundles

DeWALT weed eaters are battery operated, but not all units come with the battery. You may want to purchase a bundle that includes a battery and charger. Buying these items together should be cheaper than buying them separately. That said, you may want to forgo the bundle if you already have a battery and charger for another DeWALT device.

Folding shaft

Select models of DeWALT weed eaters feature a folding shaft. The shaft locks into place when in use without sacrificing durability, but it can also be folded for easy storage and transport.

DeWALT weed eater prices

Inexpensive: The least-expensive weed eaters from DeWALT start around 100. These tools have smaller cutting swaths and are best for small areas.

Mid-range: For between 100 and 150, you can find DeWALT weed eaters with more power. These tools are suitable for small and medium-size jobs.

Expensive: For 150 and up, you’ll be able to buy bundles or kits that include the DeWALT weed eater as well as a battery, charger, and even additional string spools.

Tips

If the soil is soft, you can turn the weed eater on its side and work it as an edger, digging straight down. Hold the device securely and make sure you’re not hitting anything hard or rocky under the surface.

FAQ

Q. How do I best maintain my weed eater?A. After using your weed eater, remove dirt, soil, and other debris from the head so it doesn’t harden and disrupt future use. Store the weed eater in a cool, dry place away from moisture and heat. The battery and charger should be kept in a similar space. Over time, you will need to replace the spool, but otherwise, a DeWALT electric weed eater should require little to no maintenance.

Q. How safe are weed eaters to use?A. Like most outdoor tools, weed eaters are relatively safe provided you understand how they work and take proper precautions. Even with a guard on the head, however, they can still fling dirt, pebbles, and other debris. Protect your eyes, hands, wrists, feet, and ankles, as these are the most sensitive or vulnerable areas of the body. Gloves, in particular, can help prevent your hands from getting sore.

As DeWALT weed eaters are battery-powered, you needn’t worry about cords tangling up, but it’s best to keep pets and children away while you’re working.

Q. What are the best ways to prolong battery life?A. DeWALT advises you to avoid running the battery down completely. Turn off your device when you notice it weakening. You can leave the battery in the charger indefinitely, as the charger’s maintenance mode prevents damage from occurring. However, you should avoid charging the battery if it is warm or hot. Instead, leave it at room temperature for an hour or so first.

Prior to the off-season, fully charge your DeWALT weed eater battery before storing it. Once the battery is dead, it can be recycled.

New DeWALT 20V Max Cordless Trimmers for 2020

DeWALT recently announced an upgraded 20V Max cordless string trimmer and also added a new pole-mounted hedge trimmer to the lineup.

They also recently debuted a new and more powerful 20V Max brushless blower, which I posted about earlier.

DeWALT DCST922 20V MAX 14″ String Trimmer

DeWALT’s new DCST922 20v Max Brushless string trimmer is an upgrade to their DCST920, which was introduced almost 5-years ago.

The new model features the same 14″ swath, which is the width of the cutting area. The trimmer has two speed settings – it can operate at either 0-4600 or 0-6000 RPM. The previous model had a 13″ cutting swath.

Press materials indicate that the new trimmer will work with DeWALT’s 0.080″ line.

The new trimmer features a hinged design that allows the trimmer to be collapsed in half, for more convenient storage.

It also features what appears to be a heavier-duty all-metal head. At the same time the weight (with no battery), has been reduced from 8.5lbs to to 7.9lbs.

Lastly, the QuickLoad spool allows for fast and easy line replacement.

• 14″ cutting swath
• Hinged shaft design for compact storage
• 0.080″ line
• Variable speed trigger
• 4600/6000 RPM settings
• Weighs 7.9 lbs without battery

Pricing: 199 for the kit (DCST922P1 with 5.0Ah battery), 129 for the bare tool (DCST922B) ETA: Spring 2020

DeWALT DCPH820 20V Max Pole Hedge Trimmer

DeWALT has also expanded their 20V Max cordless outdoor power tool lineup with a new pole-mounted hedge trimmer. It features a 22″ cutting head and can cut branches up to 1″ thick.

The new pole-mounted trimmer can extend to 7-feet long, giving users a reach of up to 12-feet. The trimmer features a 7-position 180° articulating head to suit different needs and cutting angles.

Pricing: 219 for the kit (DCPH820P1 with 4.0Ah battery), 149 for the bare tool (DCPH820B) ETA: Spring 2020

Discussion

I’m pleased DeWALT is expanding the 20v line. Whilst I’m not currently in the market for either trimmer, if I was I would immediately jump on these and make use of my investment in DeWALT 20V Max FlexVolt 60V Max batteries.

I like how the string trimmer can folded in half, as this will make storing it easier. It does make me wonder why the hedge trimmer doesn’t feature the same hinged designed. Storing a ~3.5 foot tool is a lot easier than a 7-foot one, and especially a seasonal tool that might only be used a couple of times each year.

Note: Press materials say that the pole saw measures 7ft long, but I assume that this is the maximum extended length. We’re checking with DeWALT to be certain.

What’s interesting is that some brands offer split-shaft and straight-shaft versions of their trimmers, others one or the other, with split-shaft trimmers usually being better suited for retail stores and online ordering since they fit neatly into much smaller boxes. Most of the time – from what we’ve seen – split-shaft string trimmers are designed to be assembled and then kept that way.

DeWALT designed the new 20V Max string trimmer with a hinge mechanism, and not a one-time assembly fitment, and this might give it an advantage over some other split-shaft string trimmers in its class, at least in terms of storage convenience and perhaps durability.

The 14″ swath is smaller when compared to Ryobi, Ego, and Milwaukee cordless string trimmers, but also keep in mind that some of those trimmers aren’t in the same class. The Ego, for instance, is powered by a 56V battery. Trimmers from those brands feature 15″ to 16″ cutting swaths, and some (such as the Ego) can handle thicker cutting line.

The Ego and Milwaukee trimmers also cost more – they’re priced 30 and 100 higher, respectively. The Ego comes with a 56V battery, and the Milwaukee includes an 18V/20V Max-class 9.0Ah battery.

Despite the smaller cutting swath, I find the DeWALT design to be rather appealing, given that its folding handle is designed with storage convenience in mind.

DeWALT launched their first 20V Max outdoor power tools back in 2015, starting with the string trimmer and blower. Since then they have added quite a few tools to the range, including a chain saw, pole chain saw and a 2x 20V Max lawnmower. It’s good to see the range continuing to expand.

One thing to keep in mind is that DeWALT does have two lines of cordless outdoor power tools, this 20V Max lineup and their FlexVolt 60V Max lineup. (Their 40V Max line was discontinued last year.) DeWALT’s 20V Max cordless outdoor power tools are not as powerful as their FlexVolt models, but the tradeoff is that they’re smaller, lighter, and less expensive.

So what are your thoughts on DeWALT’s 20V outdoor power tools?
