I was waiting to see whether anyone reviewed this new trimmer before buying it, but decided I couldn't wait any longer and took the plunge. It replaced a terrible corded trimmer that I had to take apart every few minutes to fix the string. The Greenworks with Lithium Ion battery works beautifully. The battery was still at fairly high capacity after about 45 minutes of trimming. Out of the box, the trimmer makes a good impression. It's solidly built. The instruction manual isn't very good (lots of repetition in the safety warnings and poorly written assembly instructions), but assembly and operation were easy to figure out anyway. I was concerned that the trimmer would feel heavy with the battery attached, but that wasn't a problem at all. Switching from trimming to edging is a snap. I love the automatic advancement of the string (especially after my old nightmare of a trimmer). The manual warns the user to keep an eye on the string after turning off to make sure that it hasn't receded too far, but so far that hasn't been a problem. I was worried that the trimmer wouldn't seem very powerful, but it had plenty of power for my needs. I have a large garden with a lot of edges to trim. No problem with the Greenworks!
Four months later (August 2010) and I still love it. I just ran out of the string on the first spool. Changing it was easy. I dropped the battery on the hard pavement and was worried I had ruined it, but there seems to be no problem--I just spent 45 minutes edging my garden and the battery still works great. I also bought the blower that uses the same battery--another great purchase! |

I unpacked and assembled the weed trimmer the same day it arrived. Easily done. During the first and only time I was able to use it, the weed trimmer began to smoke in less than 20 minutes of use. I let it cool off and tried again. It wouldn't run more than about 10 seconds so I gave up.
The manual says not to use the machine if it smokes. The manual has only a phone number to use to contact Greenworks. There is no mailing address, fax number or email address. I called the Greenworks number to talk about the warranty. After a 12 minute hold, I told a person about the problem. I was told that someone would call me within an hour for a "resolution." After two days without a call from Greenworks, I called again. This time I was on hold for 15 minutes when I gave up. I never heard from Greenworks after my first call. I then used the order confirmation email from Amazon to contact Amazon by email about the problem. That same day Amazon sent a new weed trimmer by overnight mail, even though I only paid for the lowest cost delivery on the original order. Amazon gave me about 30 days to return the old weed trimmer or I would have been charged for the replacement weed trimmer. My conclusion is that the warranty by Greenworks is worthless but Amazon stands behind the product.
I haven't had any problem with the replacement weed trimmer. It has almost as much power as a gas trimmer, as other reviewers said. I used it on thick grass under my wrought iron fence where the grass was about 10 inches high. It worked well. So far, I used it about an hour and still had about 25% charge remaining in the battery. The second time I used it there was 50% charge remaining after about 45 minutes. I am pleased with its performance. The battery charged in about two hours when it had 25% charge remaining. The battery moves easily from the charger to the weed trimmer.
I'm going to give it five stars because of its performance, including that of Amazon. If Amazon had not sent a replacement so quickly, I would have given it one star. |
Wonderful!

In my opinion, this is the perfect trimmer.
It's lightweight, powerful, cordless and requires no gas or pulling to start.
The product arrived with the battery partially charged so I tried it out before setting the battery up to charge fully. It's a great little machine.
Our late trimmer was a gas, 4 cycle monster. I could not start it or carry it.
My husband complained about the weight, even with the strap on. Horrible thing.
After trying unsucessfully to use the monster gas trimmer, I picked up an inexpensive cordless electric a few years ago. It would barely cut grass and turned out to be totally useless.
I'm so in awe of this trimmer that I plan to get other tools that use the same battery and pick up an extra battery.
I hate using gas tools and our yard is too large for corded tools.
Thank you Amazon and Greenworks! |

Background: We are on 4 acres and own a gas-powered John Deere trimmer, which works great. However, with two young boys and neighbors who also have young children, really hated the noise it made. The smoke/smell wasn't much fun either, so wanted to try something quieter. Bought my father a B&D battery-powered trimmer which he loves, but he is on 1/2 an acre... and the NickCad battery that drives it would not work on a big property. Researched battery types, and LithIon seemed the way to go, which narrowed my choice. Tried to post a good resource in this review, but Amazon took it out. Google "NiMH vs. NiCad vs. Li-Ion" and you should get some good info.
The reviews posted here were a big help, and based on the Amazon return policy (and our history of A+ experiences with Amazon) made the purchse despite a seemingly high "Lemon Rate" of ~ 20% and a lack of customer service from Greenworks.
Ordered the product Tue, June 8 and it was delivered here in northern MD on Friday, June 11, despite the est delivery date via Amazon of June 14. Very easy to put together (1 phillips screw to remove, put the trimmer head on, and then put the screw back in). The battery was 3/4 charged and gave it a test spin, and everything seemed fine. Came with an extra spool of string. For some reason, I thought this was a dual-string trimmer, but it's just one string.
Today (Sat) I gave it a hard workout after charging the battery... primarily cos I wanted to push the envelope in case there was an inherent problem... and if there was, I wanted to find out within the 30-day Amazon return period. After trimming just about everything on our 4-acre lot (dozens of young trees, bushes, and Leylands), the battery was still 3/4 charged. Total time out in the field was probably 30 minutes, and roughly 20 minutes of that was actual running time. I think we have a winner.
- Plenty of power to handle even the thickest tall grass and mature weeds
- If the gas-powered trimmer's "power" was rated a 10, then I'd give this an 8 or 9. Not much drop off.
- You do need to keep an eye on the air vents located on the head of the unit. Good advice!
- I would not use this in a dusty/dirt environment, cos all that dirt is just gonna end up in the motor
- The auto feed worked great, but if you start and stop alot, you'll probably burn thru some serious string
- The device is easily balanced and much lighter than my John Deere
- My wife and kids were outside the whole time, and she marvelled at how quiet it was ("sounds like your power washing")
- One drawback so far: If taller grass gets wrapped around the drive shaft, it is a bear to get out due to the design. FYI.
If there are any other issues, I will certainly pass them along. My prelim vote is that this is a wonderful trimmer than can be used on even the biggest yards. The high lemon rate is something to be aware of, which is why if you decide to buy, Amazon is the way to go (do you have a choice?)

Excellent product

| I love this product. I live on a small farm so it gets heavy use. The battery lasts longer than I do, so I never have to worry about stopping prematurely. It has a hard time with some types of tall grass (I'm talking 2.5 to 3 ft "barn grass") because the grass wraps around the spindle, but you have that problem with any weedeater (trust me, I know). Other types of tall grass (fescue) it handles much better, you just have to go slow. It's dynamite with reasonably length grass and easily handles thick grass up to about 2 feet tall. |
