Greenworks 40V 12 in Cordless String Trimmer, 2.0 Ah Battery and Charger

I bought this Greenworks battery-powered weed whacker as a first-time homeowner, and it has been a great addition to my yard tools. I don’t have a huge yard to maintain, so I didn’t need anything overly heavy-duty or complicated. This is lightweight, easy to use, and perfect for trimming around the edges of my yard and areas the mower can’t easily reach. I also really like that it’s battery powered, so I don’t have to deal with gas or dragging an extension cord around. For a smaller yard, it gets the job done without feeling like overkill. Definitely a great option for a new homeowner or anyone with a smaller outdoor space.

I bought the Greenworks cordless trimmer to replace my beloved 20yr old Stihl Pro string trimmer. Since we have 4 other type of Greenworks garden products, I chose the 40v to match the batteries. I must admit, I was very surprised and pleased with the light weight design and the performance of this cordless machine. The dual string and variable speed design, makes this little wonder a perfect replacement for my gas Stihl. I can edge my 1 acre fenced yard on a single charge and the design of the string (not the standard 0.65 monofilament) lasts much longer than I'm used to having string last. Plus and maybe the best part, is my wife can easily use it. The only upgrade I will purchase in the future is a "tap" style head to allow instant string advance. This string trimmer has the same quality construction and design as all the other Greenworks products that we've purchased over the past 10 yrs. Thanks for asking.

Update August 2025: Using a high quality string & winding it on the spool yourself will not only save you money, but alot of time & the amount of string you go through. The spool replacements I purchased on Amazon were all poor quality. The string wouldn't advance because it was wound too tight & it got worn down really fast. The difference between the 2 is quite obvious & I'll never buy those preloaded spools again. It's easy to load the spools yourself. It takes just a few minutes. Now that I've got good string that is wound correctly, I'm blasting through edging and thick, overgrown weeds no problem. I only have to advance the string about 2 times for the exact same areas that used to require 10+. OG Review: I used to own a Stihl gas powered, pull-start weedeater and I hated that thing. I could never get it started and if I did by some chance, it wouldn't advance new string by tapping it. It ended up sitting in my garage for years & has since been sold. I said to myself never again. I recently purchased a GW lawnmower & I've been really impressed with it. The only thing I needed was a weedeater. I went back & forth on whether to buy this, but decided to order it hoping it would somehow be easier to use. Like the lawnmower, the assembly instructions for this are poorly written. They give you the basic idea, but the rest is up to you to figure out. The clamp to attach the handle to the pole is very difficult to get aligned & in place. It requires a pair of needle-nose pliers to squeeze it together so that the handle piece can fit over it. There is nothing in the directions about this. Other than that, the rest of it was easy to assemble. This weedeater is super easy to start, stop & restart as many times as needed. I love that!! The life of the battery is good & I've used this for up to 45 minutes before it needs recharging. The string did not advance on the 1st try, so I took it apart and discovered it was wound wrong on the spool (it came that way). It was an easy fix and I've had no problems since. As far as performance, I was amazed at how easy this is to run and what it can cut down. I didn't expect it to power through thick weeds & small saplings, but it does. I managed to weedeat a huge, overgrown area that my lawncare guy has never attempted. That part of my property now looks the best it ever has. If I'd had to pay someone else to do that work, it would've been pretty costly, so the weedeater has already paid for itself. I'm now able to do all of my lawncare myself & I'm happy I can save $ after the initial investment in these pieces of equipment. I highly recommend this weedeater, as well as other GW battery operated lawn equipment. I own 3 GW's products & all of them are easy to use, affordable & hold up well.

Very easy to use and works great. The design makes it easy to maneuver without wearing me out. I like that the same battery works in my leaf blower too. Good value and gas free.

Greetings. Last year I purchased a Ryobi 40v weed eater that costs north of $200. Despite being a Ryobi fan I was never satisfied with that machine. I was very disappointed and felt like I wasted my money. Last week I went online and researched the best, budget level, weed eaters for smaller yards to service. This particular model showed up on several lists. I was somewhat taken aback because of the price tag of a little over $100 which includes the charger and battery. Honestly, I was worried that this was a cheap product. I am happy to report that I am extremely satisfied with this Greenworks 40V 12" Cordless String Trimmer. I actually think this trimmer is more powerful than the Ryobi model which cost me twice as much. The automatic line feed works great. This is also bit more lightweight than my previous weed eater. The unit is very easy to assemble in just a couple of minutes. I also love the fact that you can edge with this model. It has a small metal bar that you can flip forward and then rotate how you hold the trimmer and you now have a very capable edger. It's not a quiet trimmer but the noise level is normal in my opinion. Lastly, it seems sufficiently sturdy and built to last for quite a while. Amazon also sells the replacement spools of line. I also purchased a six pack of replacement line spools that should carry me through the summer. If you have a small yard or area to maintain and are on a budget then I think you will be pleasantly surprised with this model trimmer.

We live on a farm and my husband got this for me because I can't handle his horrendously heavy and too much to handle Stihl. It's the perfect weight, does a great job, is tough enough that it doesn't break line on concrete or sharp objects (It took me years to go through a spool). I especially like the guard on the front. My husband was perpetually killing my fruit trees with his Stihl and now I MAKE him use my Greenworks because the guard prevents him from getting too close to the tree. This summer he forgot and used his Stihl once again and killed one of my big cherry trees. Never again. We've had this for 4 years now and it's still going strong. The battery takes a bit to charge but we plan accordingly. It's been a great purchase overall.

Amazon stated in their ad that it came with a battery and charger, also stated on carton that it included the battery and charger. NEITHER THE BATTERY OR CHARGER WERE IN THE CARTON! Now I must return the entire package because Amazon only gave the option to return the entire package for a refund. I purchased a GreenWorks 40 volt leaf blower at the same time without the battery and charger planning to use the battery from the string trimmer on the blower, GreenWorks advertising says to use one battery for all of their equipment. Now the leaf blower is useless due to no battery and charger and only the battery is available for purchase- the charger is not available from Amazon or from GreenWorks website. Should you need a replacement charger at some point I would think that since it is not available NOW it won't be available if needed later. That would mean every piece of equipment you bought that you owned using the 40 volt battery would be useless, probably ending up in the trash. I will now have to disassemble the leaf blower, package it up and return it as well since I cannot get a charger. I will also be returning the extra 3 spools of dual string replacements as I have no need of them now. A total waste of time and a big inconvenience for me. I will be looking at other brands and also checking for replacement parts should they be needed. GreenWorks states that they warranty their product for 4 years. That is all well and good- if you actually GOT THE ITEM YOU PAID FOR IN THE FIRST PLACE! This was my third and fourth purchase of GreenWorks products. I'm out of the window of time to return the first two purchases to Amazon or I would return them too and look elsewhere. I am very disappointed with this purchase. The string trimmer was made in China and I would assume it was also packaged in China. I will be looking for an American or Japanese made trimmer and checking for replacement parts as well. Should I not be able to find one I will go with one with a known history of quality of the product and customer satisfaction surveys.

I replaced my 6 year old greenworks weed eater with this same newer model. My old batteries still work on this new model so I'm super happy about that! It's a little heavier but I LOVE the auto feed line and the variable speed! I'm a greenworks girl!

Es ligera en comparación a otras ya con la pila puesta, por lo que facilita el uso y manejo en cualquier lugar, yo la utilizo en lugares con declive

Para trabajos sensillos es perfecta muy sencilla de usar

Llego antes de le fecha indicada, pero la caja venia abierta y la del empaque muy maltratada y tambien abierta, al parecer vienen todos los componentes de recortadora.
