Greenworks trimmer
Have a 5 year old Husqvarna gas trimmer. Started giving trouble, part after part, decided to look at alternatives. Nothing but same old products in the box stores. Found this, here at CPO, and decided to give it a shot. This has all the power of the gas trimmer, as well as the weight. I use a 100 ft 16 gauge cord and it runs fine. Does not have the vibration or the noise of the gas model, but due to the weight, I keep it to 15 minute intervals of use. The bump advance works well. Have only went around the perimeter twice with it, but so far has exceeded my expectations.

Gas-powered performance from an electric trimmer
Aside from the cord trailing behind, using this electric trimmer is much like using a gas-powered trimmer. Good power, dual trimming lines, straight shaft. Good alternative to the fuss of a gasoline engine when you have a relatively small yard to trim.

Powerful trimmer!
I don't understand listing "trailing cord" as a Con on a corded product. I think that is actually a requirement of a corded yard tool. If it was not a desirable feature, buy a gas or cordless unit. A valid Con might be that it is a discontinued product, or that the pre-loaded spools are hard to find.

Pros would be that it is the most powerful electric string trimmer available, or that is takes the typical attachments of the higher powered gas trimmers from 4 or 5 different manufacturers.

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.

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.

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 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: Yes, you can attachments for this model. Considering the closeout price, this would be a great deal.

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.
