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

This review is based on first use with 1 &1/2 charges. . If I run into trouble and have to return it, I will update my experience. Battery life: about as expected and advertised. I trimmed f1/4 1 acre residential yard trimming heavy grass, including weeds with stalks up to 3/8" diameter& chain link fences in 1 1/2 charges. it has to run full throttle to cut the thick stuff, whereas my gas trimmer didn't. but then my gas trimmer blew up after maybe 25 uses and cost $200 and I got this one for $109 and can replace it without batteries for under $6o and it does the same job in the same time and is actually easier to use since it is lighter. Charges fast. Says 1 hour for this size battery, but maybe faster. . \Weight: unlike gas models this unit is heavy at the cutting end. The battery is extremely light weight even not comparative to it's size, but I'd still rather own two 2 AH batteries than one 4AH. The string seems to be nothing generic like you can buy in bulk and I think more durable. Operation: it is not overpowered like the gas ones, therefore I don't recommend the 20V single string model to anyone who is trimming anything in addition to regularly mowed grass such as thick stalk weeds like I needed to cut. And obviously even this 40V model is not suitable for commercial, every day use. . Regarding string feeding complaints in reviews: despite all the complaints and bad reviews here about this auto-feed design not feeding out, I had no problem with mine. I think the bad reviews based upon the supposed non feeding issue are due to the reviewers not reading the instructions. If they called support, i suspect the issue was resolved and they've all been too lazy or perhaps personally dishonest to change their reviews to reflect their mistakes. But if I am wrong and mine has an issue, I know I can depend upon Amazon and GteenWorks to resolve the issue for me. Feeding discussion continued: twice the string got short and i had to do what the instructions say, which is to pull the trigger for 2-5 seconds and then let off the trigger for 2-5 seconds before resuming work. one time when one string went up inside the spool, I had to take the spool out and refeed the line through the hole. Twice more I had to press the button in the side of the spool hub and manually pull out the strings on both sides. But most of the time it fed out automatically just as it says it does. And frankly, it works at least as well as my old bump feed one and if it stops auto feeding entirely, I would put up with having to stop once in a while and manually extracting the lines as described above, it works that good and costs so little comparative to rival products. . I also almost sent it back the same day, today. because I placed it on charge after I finished the yard and in about 5 minutes the green "done" light came on and would not go off even if I unplugged everything and plugged it back on, it went right to "done charging". intent on sending it back I disassembled it and threw it in the box and went online and requested a return. Amazon automatically created a new order to replace it at 0$ an said I had a month to return this one. So then I looked at the battery again, which I had left in the charger plugged in, and it was charging and the read "charging light was on. It finally took a full charge.supposedly if a hot pack is plugged into the charger, it says teh hot pack indicator light is supposed to be orange. Well I am assuming that that was the problem, a hot pack, but the orange light never came on, just the red and green ones. So I am assuming that there is a minor malfunction in the charger either once or permanent that didn't let it show the "hot pack" delay it was in before I packed it up. I greatfully unpacked and reassembled it because I don't like being suckered by garbage products for any amount of $. I'd rather be wrong and have to repack and unpack something than actually have to return it because it's phony garbage. The only pleasure I get out of that experience is when i'm smearing the truth all over Amazon about my bad experience with the product with almost vengeful zeal.

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.

works as described able to do whole yard on a single charge

This cordless trimmer is powerful and makes weed eating effortless. The battery provides long life to complete the task!

I've been using this string trimmer for almost two months now, and it's been great. What impressed me the most is the battery life—I can trim my entire yard about twice before I need to recharge it, which is more than enough for my needs. It's also surprisingly lightweight, so my arms don't get tired like they did with my old gas trimmer. Another huge advantage is not having to deal with mixing gas, filling the tank, or worrying about gas leaking while I'm cutting. I just grab it, press the button, and get to work. The auto-feed line has worked well, and so far the trimmer has been reliable with no issues. If you're thinking about switching from a gas trimmer to a battery-powered one, I definitely recommend this model.

It’s great but should have 2 batteries

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.

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
