    Review of:
    Greenworks 14inch Cordless string trimmer 40V 4Ah Battery & Charger included #21363
    Yesterday morning my Greenworks battery powered weed eater arrived. With the help from JJ (my dwarf pit) I opened the box and got the weed eater out and all parts. Assembly was pretty easy as all one had to do was put on the weed guard and the handle. But before even that I put the 40volt 4ah battery on to charge. I already had a 40volt 2ah and charger from the Greenworks 12 inch chainsaw I bought a few weeks ago. That is already reviewed on Amazon. For the first charge it took about an hour.
    While waiting on it to charge I looked around the house and in the shed for some safety glasses. All I could find was my wife’s shooting range glasses. They would work just fine but I bet I looked stunning sporting safety glasses with pink rims. LOL!
    In case you are wondering why I am slowly converting what I can afford of outdoor work tools over to battery power versions I am tired of the pull pull pull yank pull pull pull of trying to get the Ryobi powerhead to start. I have to admit that I do work the poor Ryobi hard as I have an acre of land. And since I have all the attachments the powerhead fulfills the job of weed eater, pole saw, blower, and cultivator/mini tiller. But, I have to buy a new one just about every season. So, this season I am over it and my rebuilt shoulder is over it because by the time I get the dern thing running and staying running my shoulder is already singing. So, that is why I finally got desperate enough to try out the supposedly better more powerful battery class yard tools.
    I took it outside and to the front of the house and looked dubiously at the span of high weeds that were standing about 2 foot tall. They had not been weed whacked since mid last season as I hate weed eating with a passion. All the vibration from gas powered weed eaters really hurts the shoulder.
    The first thing I noticed that this Greenworks is HEAVY. Please let no reviewers tell you otherwise. There is no getting around the fact it is heavy. Just as heavy as the Ryobi powerhead with an attachment. Also note that NO shoulder strap came with my Greenworks unit.
    The Power:
    But back to the point. The weeds were there giggling and laughing at me with my brand new battery operated weed eater showing no fear. It was such a blessing to be able to just push the power button, squeeze the safety trigger and pull the regular trigger and it fired RIGHT UP! Holy Cow! I am NOT exhausted and angry before I even start a job! The weeds however were not impressed as there were so many of them. I pushed the other button and it went to High setting and it really sped up and sounded powerful. The weeds took notice and I think I saw them start to tremble with a little fear. Feeling more confident I went to work. Oh the slaughter of the weeds!!!! How horrible! (from the weeds perspective) As for me I was grinning like a maniac working from the top down. This thing was doing what it is supposed to do. Weed Eating! Now to be fair the weeds did not have any woody ones to beef them up. I had pulled all that during the winter. But they were still masses of them and laid in thick. They did not stand a chance.
    The Bump head:
    When it came time that I needed more line I whispered a little prayer. NO bump head I have ever used worked properly. NONE. That always forced me to use a 3rd party head that you insert cut line into. I did a light tap on the ground and holy cow it worked! Color me impressed!
    The Vibration:
    Yes, it has vibration. BUT, and I say BUT! It is no where near as bad as a gas powered unit. My shoulder, arms, and hands, said THANK YOU very much!
    The Balance:
    I had no problem with the balance of the Greenworks unit. I am 5′ 6” and it felt fine to me.
    Battery Life:
    I kept it on High setting for about 25 minutes before stopping because I wanted to save something for a video review I am planning to do. Battery was still running it.
    Noise level:
    After about 15 minutes of run time my daughter in law came around front. I was able to hold a conversation with her while working. With a gas powered unit that is impossible. No, it is not whisper quiet. But you can still talk with out shouting your head off and filling the conversation with a bunch of WHATS?
    Attachment abilities:
    The reason the DIL came round was she had been busy herself along with the grand kids. That is also why I called a halt to the weed assault after just 25 minutes. I went around the side of the house and she had been busy cleaning and straightening up. She wanted me to blow the masses of dead leaves that had gathered on the side of the house all winter. I went to the shed and brought out the Ryobi Expand-It blower attachment. It went on and clicked and tightened down with zero problem. (after the job was done I tried all the Ryobi Expand-It attachments I had and they all fit) With the blower attachment on and the setting still on High I went to work. It was blowing a ton of weeds with a wet bottom layer around with zero problem.
    Battery Life/run time High of 4ah battery continued:
    After about five minutes the battery gave up the ghost. So that gives the battery a total of about 30 minutes on High setting with most of it being in high weeds. Not bad. Next time I weed whack I will not need the high setting.
    I went in and put the 4ah on the charger and brought out the 40volt 2ah battery I had from the chainsaw. Fit perfect. I finished the blowing of the leaves to out in the yard. Then the DIL wanted a turn with the weed eater attachment. So I switched back over and she took a tentative turn getting bolder as she used it. She went about five minutes and declared it good saying she would be able to use it. She is about 5′ 3”. (please don’t giggle there are no giants on either side of either family) The only thing she did not like was the weight. She to was hoping it would be lighter.

    Over all impression:
    With the weight and no shoulder strap being the only downfall I was really impressed with what this thing could do and very happy that I had to buy no separate yard tool attachments as the Ryobi Expand-It attachments do fit perfectly. I am so impressed that when I can afford it I will be adding another 40volt 4ah battery to the arsenal (one acre peeps) and also am heavily considering the 19” Greenworks battery powered push mower. That is the long range goal as money allows.
    As for the longevity of these yard tools and batteries? I am sorry at this time I can not attest to that. We shall see. But currently really love both the chainsaw and this Weed eater even more.

    Actual rating: 4.5 stars. Dinged half a star because of the weight. But if you are sitting on the fence about buying this product. Hope off the fence and go on and buy it. I think that you to will enjoy it. Well, as much as one can enjoy yard work. 🙂

    I needed a new string trimmer, because I was tired of my old Echo trimmer nickel and diming me for repairs every year. My neighbor recently bought a battery powered trimmer (not Greenworks) and he has raved about it. So, my research began, and it led me to Greenworks. It seems Greenworks G-max tools offer a good bang-for-the-buck, so I took the plunge. I have been very pleased. Here are my thoughts…

    Battery Life: battery life is surprisingly good. It will run for 50-60 minutes of cutting, with 85% of that time on grass using normal speed, and the other 15% on “turbo” for thicker grass and weeds. Personally, after 1 hour of trimming, I am ready to quit, so 50-60 minutes is plenty.

    Cutting power: Power for normal around-the-house trimming is excellent. I had no trouble cutting all around the house, edging my patio, cleaning around the end of my culvert, and edging my driveway, and I did it all in one charge.

    Trimmer head: So far, the bump feed head has worked really good. We’ll see how it goes when I have to replace the string.

    Ease of use: Superb. No messing around, no fumes, no ear plugs required. Hit the power, and squeeze the trigger.

    I haven’t used any other attachments yet, but It definitely seems like it would have the power to run, say, a pole saw trimmer for a short time on small branches. I have a brush cutter attachment also that I will try at some point for no more than medium size, non-woody weeds. I do not think it has the power to cut big, tough brush. In fact, there were several times that I tried to bite off a bit too much at one time with the string head, thick tough weeds wrapped around the top of the string head, and the motor instantly stopped and beeped at me. Apparently there is an overload safety built into the motor controller that will shut it down to prevent damage. No big deal, I just untangled the weeds, hit the power button again, and kept on going. I will use this cutter for grass/spindly weeds 98% of the time, and I couldn’t be more pleased than I am for that purpose.

    If I had to give a downside: The manual is terrible. The English is bad, and it contradicts itself in several locations. Don’t even bother reading it. Charge battery, insert battery, trim weeds. If you’ve used a gas powered trimmer and a cordless drill, you have all the knowledge you need to operate this trimmer. Greenworks needs to hire someone who uses English as there first language to write the manual.

    Here’s a tip if you do try one of the Greenworks tools, like it, and want to expand your set of compatible equipment: Don’t purchase just a battery.
    After I bought the trimmer, I also purchased the 

    GreenWorks 24322 DigiPro G-MAX 40V Cordless 185MPH Blower/Vac with 4ah battery and charger

    . It makes no sense, but the blower/vac, battery, and charger combo only costs 20 dollars more than the 4 amp battery alone, whereas the blower/vac costs almost $100.
    4 amp battery: $124
    Blower/Vac + battery + charger COMBO: $145
    Blower/Vac ALONE: $98
    All prices are rounded, and were current at the time of my purchase. Your mileage may vary, but my point still stands.

    I don’t think all homeowners should abandon 2 cycle motors yet, but based on the performance of this trimmer that day is coming soon. I plan on purchasing more G-max tools in the near future. There is an 80V line of tools from Greenworks (and other manufacturers) that may or may not be better, but for the money, the 40V G-max trimmer has been fantastic, and I don’t regret saving the money over the 80V system.
