Along the way, homeowners spill more than 17 million gallons of gas while refueling. That's equivalent to the 1989 Exxon Valdez disaster. It's time to move beyond clumsy, harmful gas-powered mowers. It's time for GreenWorks to be your lawn tools for life. Power cord not included.

The auto feeder works by pausing operation of the tool for a few seconds and as it slows down it spits out the string like it's supposed to

Reviewed in the United States on June 15, 2018

Size: Tool OnlyStyle: 40VVerified Purchase

I was a little leary of this tool after reading some of the one star comments. After receiving this tool from unboxing to operation was less than 10 minutes and that was without reading the directions. I had to lol about one review saying it's hard to change the black handle to different positions. Lol your not supposed move the handle, you move the 2 pivot points on the tool which gives you a wide array of positions. The auto feeder works by pausing operation of the tool for a few seconds and as it slows down it spits out the string like it's supposed to. Conclusion: some people should not operate any kind of power tools if they have no clue how to use them. Ignor the negative comments. BTW I have an average size yard and was able to Edge, trim and switch over to my blower all without a charge in between. Great tool. Oh 2 more comments about the negative reviews. One said the tool has all it's weight at the bottom which makes it difficult to operate. Yes that is true until you put the battery in. It then becomes a decently balance tool. Also I read the handle is flimsy. I imagine it would be if you didn't lock it in place. Best $50.00 weed trimmer out there. Have a good day.

Gets the job done for a decent price!

Reviewed in the United States on May 9, 2016

Size: 4 AmpStyle: CordedVerified Purchase

I purchased this trimmer as I have a fairly small yard, 10 x 10 in the back and a small patch in the front of our drive way. Since we recieved a notice to do something about the unkempt yard, this was an easy solution. The package came together in the original box from GreenWorks with a shipping label slabbed on top. To me, this is much more effective than repackaging in another box. Assembly was very easy provided you have common sense and know how to use a phillips head screwdriver.

ONE IMPORTANT THING: this is an electric trimmer and as such, will need an extension cord to use this. It was not clearly stated on the website but is not a huge deal since one is ~$5-10 range.

I used this to hack down the almost foot long range of weeds in my backyard in about twenty minutes flat. This thing has impressive power and the automatic feeding spool is very convenient.

Definitely would reccomend this trimmer if you are in need of a simple solution like the one I had. Please give it a shot as it is fairly priced and gets the job done right the first time.

I write these reviews to help my fellow Amazon community. If you found this review helpful, please mark helpful on the comment. Thanks!

The unit works great once I replaced the trimmer line that came with it

Reviewed in the United States on July 16, 2016

Size: Tool OnlyStyle: 40VVerified Purchase

The unit works great once I replaced the trimmer line that came with it. I'm using RINO-TUFF .065" Universal Trimmer Line I picked up at Home Depot. The problem with the supplied line is it was fused together in multiple places on the spool (it's like it was wound on the spool before the it cooled - basically a manufacturing defect) so there are a bunch of places where it gets stuck and can't feed off the spool. Making things worse is even if you unwind the entire line and then rewind the entire spool in an attempt to fix this problem, the places where the line was fused to an adjacent winding are weakened so they just break way too easily. So I just pitched the line that came with it and instead used the RINO-TUFF line which I already had for use on my previous trimmer that finally died after decades of use. The result is the trimmer works perfect now. Note; it does not really "auto feed" the line, instead it will advance it about 1/4 inch each time you start the unit - so that's good to know. I've also read some reviews complaining it is not well balanced, which I don't agree with as you can easily adjust the handle to change the balance, although I found it to be well balanced centered right in the middle of the range it can be adjusted. My advice to GreenWorks is to have a look at the spools getting shipped as this is likely the culprit for many of the complaints I've seen. Quite honestly if I had not had the RINO-TUFF line handy to give a try I would have likely just returned the whole unit.

Someone who actually knows something

Reviewed in the United States on May 19, 2016

Size: 4 AmpStyle: CordedVerified Purchase

I just ordered another GreenWorks 21212 4Amp 13-Inch Corded String Trimmer after three years of hard use on the first one. I live on the edge of the high desert in Oregon and I have been cutting my entire ½ acre property with one of these. This includes wire fences, rock gardens, ironweeds that grow up over a septic leech field. These are great trimmers BUT there are a few things you need to know to make them work right.
These are dual sting and the automatic advance will only work properly when you are using both strings. This brings us to the replacement spools sold by various companies which DON’T even fit the trimmer. So forget them and get a 200-300 spool of .065 round (I say round – I have not tried the edged string) string and re-wind the original spool which came with the trimmer. There is an arrow on top of the spool which will let you know in which direction to wind the spool. BOTH strings are wound in the SAME direction. To get the string started in the spool there is a slot in the spool and slip the string in the same direction of the direction you will wind. This locks the string in place and allows you to wind.
How to get the trimmer to advance once you have the stings loaded. AUTOMATICALLY – understand that there is no sensor in the trimmer telling it to let out more string. The string is advanced EACH TIME YOU LET OFF THE POWER and the spool is allowed to come to a complete stop. Just before it comes to a stop, you will hear a slight click from the spool. This means that it has reset the advance and when you give it power again, the strings will advance. You can stop and start the trimmer as many times as you like until the stings are where you want them. MANUALLY – you can advance the strings manually by turning the trimmer on its handle and looking at the spool for a little black rectangle button on the spool. Jiggle that and play with the string and the string will advance.
This trimmer is 4 amp which means there might be brush or thick weeds which you cannot get through without the motor straining. You can work around this. Go to one single string. BUT be aware the automatic advance will not work properly with only one string. So you will have to manually advance the string. This will reduce the drag on the strings and allow you to cut thru thicker grass and weeds. The cut will not be a neat and you might have to make two passes BUT the motor will probably not bog down.

I am happy with it but since it is my second one ...

Reviewed in Canada on June 24, 2017

Size: Tool OnlyStyle: 40VVerified Purchase

I am happy with it but since it is my second one after 5 years of use,here is my desapointment.
The only down side is i cannot use my other batteries 40 volts on it because the compagnie added a little plastic protector between the batterie contactor making the use of my previous batteries not to be usable?
I had to use my old trimmer upper part connectedwith the new trimmer to be able to use my batteries so living the new upper part aside.
Thanx for reading!
