Greenworks 14-inch 40V Review

The Greenworks 14-Inch string trimmer overall failed to distinguish itself from the rest of the products in the group in the bulk of our tests, only standing out in our battery life metric. This weed eater isn’t terribly expensive but can’t quite compare with some of the better products, which don’t cost that much more. However, it is a decent bargain option if you only have light-duty string trimming tasks.

Our Analysis and Test Results

While the Greenworks produced mediocre results in the vast majority of our tests, it did thoroughly impress us with its battery life, lasting two to three times longer than the bulk of the other string trimmers. It doesn’t have a ton of power but this product would be a great option if you have vast expanses of easy-to-trim plants and don’t want to have to stop and recharge the battery.

Performance Comparison


The Greenworks does a decent job at clearing away patches of grass and weeds that aren’t too dense and can even cut through some of the burlier brush and plants if you take it in stages. The guard does a good job of blocking freshly-cut debris from getting thrown back at you and it has a bump feed mechanism to dispense more line. The shoulder strap attachment also makes it a bit more comfortable and less fatiguing to use.

The Greenworks truly shined in our battery life test, where we ran each trimmer under no-load conditions until they died, scoring based on the runtime achieved. This weed eater lasted for an impressive 95 minutes before calling it quits — easily one of the longest runtimes of the entire group. It also has both a low and a high power mode, so you can adjust the speed to the task at hand.


Unfortunately, the Greenworks is significantly underpowered compared to many of the other models in the group, faltering with thick-stemmed weeds and dense patches of plants. Even worse, the guard frequently gets caught up tall grass when cutting thicker patches, which then become almost immediately tangled in the head and force the Greenworks off course. This guard also gets in the way when trying to trim tight spaces or make precision cuts.

This is one of the heaviest string trimmers of the group and feels particularly cumbersome and bulky to use.

The shoulder strap does mitigate this a bit but doesn’t do all that much.

We also thought the Greenworks is one of the least user-friendly models when it comes to replacing the line. The spring mechanism inside the head especially makes it difficult to keep the string where it is supposed to be and replace the cap without cross-threading it.

This weed eater is also one of the loudest trimmers we have tested to date, with a particularly high-pitched tone that is quite grating on the ears.


The Greenworks is an acceptable bargain buy but there are less expensive models that we vastly preferred.


If you need to cut copious amounts of sparsely spaced weeds and grass, then the Greenworks is a great choice. Otherwise, we would recommend an alternative option.

The Greenworks 21212 is an affordable and functional electric string trimmer with a 4-amp motor. This weed eater is fairly basic in terms of its feature package, which is something you might expect from a cheap weed eater, but it manages to do a lot with its features.

The 4-amp engine is not the most powerful of the products we reviewed, yet it has plenty of power to get rid of most of the overgrowth in your yard. The shaft is on the short side, and while it is adjustable, it doesn’t extend far. If you are taller than 6 feet, this trimmer may be too small. While the head doesn’t rotate for edging, the shaft rotates to make it comfortable to hold for edging.

The retractable metal flower guard doubles as a guide when you use it in edging mode. This is not as easy to maneuver as a pivoting head with wheels, but it’s nice that you can perform this kind of detailing on your lawn with a trimmer at this price point. It is a lightweight trimmer at 5.2 pounds, so holding it at different angles is easy. The small-sized shaft comes in handy when you use it in edging mode as well.

The 13-inch cut path is decent and should handle most of the cutting and trimming in your yard. It also has a single-line auto line feed so you won’t have to worry about manually adjusting the spool every time. If you want a wider cutting path, consider the other Greenworks model we reviewed.

As with all electric weed eaters, this trimmer releases zero emissions into the atmosphere. Greenworks prides itself in manufacturing products that environmentally friendly.

Greenworks 24V 12-inch string trimmer / edger review

REVIEW – A reliable string trimmer is an indispensable tool for yard work. However, gas models are loud and create noxious fumes, and corded electric units are inconvenient. The Greenworks 24V 12-inch string trimmer with edger mode is a lightweight, feature-rich, battery-powered tool. I have one to review. Read on to see what I think!

What is it?

The Greenworks 24V 12-inch string trimmer with edger mode is a battery-powered string trimmer for yard work. In the United States, the string trimmer is also referred to as a weed whacker, weedwacker, or line trimmer. The handle side of this unit has a small battery that is charged by an AC adapter and the cutting side has a small electric motor attached to a monofilament line. The motor housing may be tilted to make it easier to operate on steep hills or embankments. The motor housing may also be rotated 90 degrees to convert the string trimmer into an electric edger. The vertical edger can be used to create a distinct boundary between the lawn and another surface. The debris guard of the trimmer has an attached wheel that makes it easier to guide the trimmer along the ground to create boundaries with a paved, concreted, or asphalted area.

Design and features


The Greenworks 24V 12-inch string trimmer with edger mode comes in a plain cardboard box. The components are loosely packaged within the box.


The Greenworks 24V 12-inch string trimmer with edger mode must be assembled before use. A screwdriver is required to install the trimmer guard but a much more important item is required before use: safety glasses. String trimmers, even with a plastic guard, can jettison sharp-edged debris at high velocity. This debris may be ricocheted off of nearby objects into the operator’s face.

Assembling the trimmer is relatively easy. The steps involved include attaching the guard, assembling the shaft, and attaching the auxiliary handle. The guard is attached with three Philips head screws. The trimmer guide, a steel loop that indicates the approximate full length of the wire, fits onto a channel above the guard.

The shaft is pre-wired from the handle and battery on one end to the motor on the other. The shaft is designed from aluminum and has an adjustable length. When using the trimmer the handle height adjusts from about 25″ to 32″ from the cutting height and when using the edger the handle height adjusts from about 28″ to 36″ from the guide wheel height. The auxiliary handle fits on the top of the adjustable shaft. The position is adjustable along the entire length of the shaft and is tightened to the shaft with a hand knob on the right side of the top handle.

The directions do not explicitly indicate that the protective paper should be removed from the line trimmer, but this step should be done to prevent the line from getting too long.

The spool will release about 0.4″ of line each time the machine is started. At first, I thought that this may be too much line released at a time, but based on the length of the line I have observed when using the trimmer, this is about right. Several times I needed to advance the line before starting the next trim. This is accomplished by starting the trimmer and then stopping it. The length of the cutting line is controlled by a centrifugal clutch that engages when the head is turning relatively slowly. You can see the clutch button here on the base of the rotating head.

In the pictures below you can see that the clutch button is released when the head is spinning slowly but as the head speeds up the clutch button sinks and prevents the spool from further advancement. each time this happens an audible click is heard.

The trimmer comes with a spare spool and spool cover. Each spool is loaded with 14’6″ of filament. By the math, this corresponds to 420 startings of the trimmer. I figure with my use, I may start this about 40 times each week when I trim the walkways, dog pen, trees, pavement, and beds around the house. Even if I need to replace the spool every ten weeks this doesn’t seem like too much of a hassle. The filament may be replaced onto the spindle by tucking in about an inch of the filament into the center of the spindle and then winding in the direction indicated by “rewind →”.

The inch of filament is caught in the channel pictured below.

One design issue that I wish was more robust is that the tool is not protected from rain or water. the directions require that the vent holes for the motor be brushed off and that the unit be cleaned with a neutral detergent. I wish that the tool could be cleaned with a garden hose.

The battery on the unit I received for evaluation is only designed to power tools but the battery on the unit sold by Amazon has a USB port on it too which allows the 2Ah battery to be used as a high capacity USB charger. The battery has a 3 LED energy level gauge. The gauge is not accessible or viewable when the battery is installed but installing and removing the battery is very easy. Additional batteries may be purchased for between 40 and 50 dollars.


The operation is very simple and as easy to use as a typical string trimmer. If you are used to a unit that requires bumping the head to advance the line, then this unit is a little different.

greenworks, 14-inch, review, electric, trimmer

The line is advanced automatically each time the unit starts. To advance the line significantly start the unit momentarily, wait for it to come to a stop, then repeat until the desired line length is reached.

The length of the shaft is adjustable with a cam lever so it may be changed without additional tools.

The rotation of the head for edging and the angle of the head are easily changed with a press of a button.


The string trimmer works similarly to gas-powered trimmers I have used in the past, with the exception that it is lighter weight, quieter, less costly to operate, and doesn’t produce noxious exhaust. Like other trimmers, it works better if it is used to cut with the tip of the unit, and the cutting is from the right to the left so that the trimmer is cutting into the guard.

This video shows the trimmer at work around a tree.

The edger also works very well. It was easier for me to use the edger freehanded rather than relying on the wheel, but the performance was very good.

Final thoughts

The Greenworks 24V 12-inch string trimmer with edger mode may cause some green thumbs to wonder if it is powerful enough or lasts long enough for their yard. While I cannot recommend this for commercial landscapers (the unit is not warranted for commercial use) I believe that many readers will be very happy with the Greenworks 24V 12-inch string trimmer’s performance and the quiet, pollution-free operation of its battery-powered motor.
