I researched electric string trimmers thoroughly before opting for the
Greenworks 21142. So far its performance has been impressive.
It was easy to assemble, has strong power and is not difficult to re-string.
Throw in a 4-year warranty and I don't see a competitor that can touch it.
Thanks to Tyler Tools for great customer service and fast shipping, too.

Great Product
It was a snap to assemble and easy to use. The only negative is the cord but I knew that going in and wanted the quiet power and light weight you get from 120V. I purchased this product for the tall thick grass around the cabin and it doesn't disappoint. Make sure to use a good extension cord (14 awg or bigger) especially when it's longer, otherwise it will over tax the motor and the cord will heat up. You can get by with a 16awg for short, lite jobs but keep the length as short as possible. I've been using this product with no complaints and I'm actually very happy with it.

Power of gas, convenience of electric
I used it for two days to trim around the yard. It is powerful with a wide swath. I had to switch to the smaller trimmer in tight spaces but I could easily reach under areas that previously were difficult to impossible to reach. It never bogged down but had to be careful around small steel stakes. It will grab them fast. I made a shoulder sling to help take some of the weight but the top motor helps keeps the unit well balanced. With all the trimming around trees and plants in my medium size yard, the electric cord takes planning and no need for gas engine maintenance and noise. I got a five year old gas trimmer a number of years ago. I never got it running enough to do the yard. I know that small gas engines run well but become temperamental as they get old.

Power!
Awesome power comparable to my Ryobi 2 cycle pain in the butt to start gas trimmer. After a while pressing the top button and the bottom button gets uncomfortable to press at the same time (I have arthritis so that is a factor). Would like to have a shoulder strap attachment added for a few bucks more. Overall a great trimmer

Best thing since gas!
I started with electric trimmers . . . I had about 3 of them. Then I "graduated" to gas. For the first 2 to 3 years, everything was fine, and then problem after problem. I threw it in the trash. I was very skeptical about going back to electric after getting used to the power of a gas trimmer. I read all the reviews online that I could find on this product and felt fairly confident ordering this unit. I'm glad I did. It works just as stated. It has a lot of zip, and does everthing I need. . . . trimming and edging. The ONLY drawback is toting the cord around, but that's what you buy into when you get an electric unit.

Great wacker
Whacked down an entire large yard of weeds 3 ft higher and taller with no problem in a short morning. Someday it'll be landscaped, but this will keep it down until then.

I shopped for this trimmer because the craftsman heavy 4 cycle gas trimmer I've been using became hard to start and blew out a clutch as a result of the heavy weeds I whack. This electric trimmer gets a little heavy after about 30 minutes so I will attach a shoulder strap. Dragging a cord is the trade off but not that bad. I wish the string was a heavier gage like the craftsman twisted line lasts well despite heavy use. Electric is clean and quiet . . . invent a solar powered trimmer and I'd buy it !!!

Powerful machine!
This product replaced my tempermental gas powered Ryobi trimmer. I don't mind dragging the long electric cord; no more frustration like I had with the old gas trimmer.

BEST ANSWER: Greenworks is not interchangeable with other brands.
We are interested in the 21142 model of the electric string trimmer. We read that it is the top seller, and just now saw the question regarding the fact that is no longer avalable. Is this true?
Also, where is it made?
Thank you.

This Greenworks 21142 was the top-rated corded electric trimmer in Consumer Reports May 2013 issue. Is it really discontinued? Poor marketing!

Can you buy the attachments for this model 21142?

Is this a wise investment being it is discontinued?

BEST ANSWER: Greenworks 29622 Replacement Dual Line Spool for Model 21142
I have an older version of this trimmer with the 29402 trimmer attachment. The "tap and go" head is quite worn and I was wondering if there is a replacement part available for it?
AndyC on May 16, 2016
BEST ANSWER: CPO does not carry replacement parts. Contact Greenworks Direct for parts. 888-909-6757
How do you reload the spool with line? I have seen videos that say there is a hole in the center of the spool but there isn't on mine.
