First impression is positive
Plenty of power. Line is a little wimpy. May have to see what I can do to improve the diameter of the line. I have read on-line that string replacement can be challenging. I have not had it long enough to have to replenish the string. My main complaint is that the trimmer head rotates counterclockwise- so debris is thrown against my feet since I am right handed. If I could figure out how to make it rotate the opposite direction I would. That would be a big improvement. Other than that I am quite happy with it the 3 times I have used it so far. Check back with me at the end of the mowing season.

Thrilled with this trimmer
I used my trimmer for the first time yesterday and was blown away by its quality. It is extremely well built and very balanced -- easy to hold. The power is terrific: loads of torque.

It's pleasant to see this level of quality at this price point.

As someone that use my ears for work, the 10 amp 18 inch corded string trimmer is quiet compared to a gas trimmer and for that I'm thankful.

So powerful it twists with torque in my hands. Power of a gas weedeater but quiet electric! Very happy!

Power and Strength!
We have some pretty tough vegetation here in south Texas, and .065 string just doesn't do the job - would go through over half a spool in one cutting! So glad to have the thicker string offered in a corded electric trimmer. I've never had a bump feed trimmer before, so I need to get more familiar with that function, but this tremor is powerful and durable...perfect for tougher stuff!

Finally, a strong electric trimmer!
An electric that handles and performs like a gas trimmer, but without the noise and fumes. Holds heavy weight line, capable of going after overgrown grass and weeds without wimping out.

Cuts better than my other trimmers I use. Easy rewindable and removeable line spool.

The strongest corded electric string trimmer made, maybe the only one as powerful as strong gasoline-powered products.

The user manual describes a different string spool assembly cover and says the spool can be accessed by unscrewing a plastic cap at the end. Actually it's held together by a pair of snaps on the sides that have to be squeezed together to release the cover. A 6" long metal rod is included but not documented. It's for holding the driveshaft so it doesn't turn when removing the entire string spool assembly but is not needed for just changing the string.

Works like a champ!
I have had this for well over a year. It's powerful. I replaced a gas trimmer I had which has a fuel line break. I have a large front and back yard and this has no challenges with anything I throw at it.

BEST ANSWER: Greenworks 29622 Replacement Dual Line Spool for Model 21142. $9.99
will this work with try-bilt attachments?
E on Jun 8, 2016
BEST ANSWER: "Quick-connect coupler allows for easy attachment changes and fits various name brands."

The staff member who said you can't use attachments other than Greenworks didn't know what he was talking about. It will work with any standard attachment, so if the Troy-Bilt attachment uses the standard attachment then yes it will work.
I just bought a 21142 trimmer. Works great, but cord was used up quickly. What cord head can I order?

I tried SUN-31106524 at Greenworks.com, but they don't list it.
What do I buy? Where?

Please help!

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.

How do you advance the string?
A shopper on Jun 22, 2017
BEST ANSWER: The same as any string trimmer. Tap the head on a hard surface.
I like mine.
Can you buy the attachments for this model 21142?

Is this a wise investment being it is discontinued?
Cam on Aug 4, 2016
BEST ANSWER: Yes, you can attachments for this model. Considering the closeout price, this would be a great deal.
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?

BEST ANSWER: CPO does not carry replacement parts. Contact Greenworks Direct for parts. 888-909-6757
