Greenworks (18") 10-Amp Electric Top Mount String Trimmer

Good product for the money. However the instructions for the head removal and line changing is not aligned with the product received. Customer service was very helpful! Online information was also very helpful.

Switch didn't work for long. Where can I purchase new switch?

First of all, the "bump-feed" head sucks like all of them do no matter what the brand (even Husqvarna) thus the 4 stars rather than 5. So be sure to get a universal quick-change head - Grass Gator, Pivotrim or whichever one you like. I like the 4-line push-n-load made by Shakespeare, it is a little challenging to figure out how to put it on unless you are fairly mechanically inclined (you have to follow their installation instructions for curved shaft trimmers with a little improvisation in spacer stacking...go figure). Finally use the 0.095" triangular yellow Rino-Tuff HD line.

I had a medium sized back and front yard with two foot high weeds and snarled cut-grass with blackberries, ivy and holly hedges to cut and trim and I only had to load new line twice even though cutting right up next to fences and concrete foundation and even stripping moss and grass clumps that had partially grown over a backyard sidewalk. The Shakespeare head uses two 18" pieces of line that just push halfway through for the 4 lines. I loaded once at the beginning and again halfway through without having to stop and clear the head of weeds wrapping around.

OK, that's out of the way so on to the power head itself...it is an Animal! It did not bog down at all even slinging 4 over-sized lines while cutting through heavy vegetation, in fact it makes a very awe-inspiring sound, kind of like a giant swarm of angry hornets and the motor housing was just barely warm after all the trimming was done. The motor being on the rear part of the trimmer provides excellent balance when using a shoulder strap while weighing 25% less than a gas trimmer without all the stinky gas and oil mixing mess to worry about.

My brother came over and tried it and has decided to order one for himself. It easily out-does the Ryobi 23cc gas trimmer I used to have and should actually have all the power needed for all the available attachments from TrimmerPlus, Ryobi or whatever uses a square drive. Plus a four year warranty - I really like this trimmer!

I have had nothing but bad experiences with every electric string trimmer that I have ever purchased until this one. They have all been poor quality and ergonomically awful and uncomfortable to use.

This trimmer is by far the best design that I have found.

The design of this trimmer is exactly the same as is found with gas powered trimmers- the motor is at the end of the shaft to balance the cutting head and the shaft is straight, not curved. The overall result is a much better balanced, much easier to use trimmer. It also has more than adequate power for tall weeds in my large yard.

The only problem so far is the bump feed string head. IMHO this is a design flaw common to all residential use trimmers. As soon as I can, I will be replacing the bump feed string head with a suitable replacement.

Finally someone has an electric string trimmer that acts like a gasoline trimmer. All the ones I have tried to use in the past were so weak it was futile. Maybe our grass is tougher here in S.E. Arizona, but they just did not cut it. (pun intended)

I have two ineffective electric trimmers in the barn that are worthless. This one really works and I am very happy with it. Due to a shoulder injury I can no longer start a gasoline string trimmer. Now I don't see that as a problem.

Thanks for a good product.

I got tired of using battery powered trimmers which would bog down and run out of power, and did not want a gas trimmer. I was amazed at what this trimmer can do. It has plenty of power, easy to operate, and the balance of weight is excellent. I never operated an electric trimmer that performed with this much ease and power. The trimmer is an absolute beast and well worth the money.

It use .020 trim line not .080 as the vendor says, switch has bad design, it is a double effort to get it works steady and it hurts your hand..

The trimmer is made of sound metal and should last me a long time. I think a shoulder strap should come with the trimmer, gets a little heavy after awhile and loves to eat up string. Still the best on the market for an electric trimmer.

I have used this extensively since I purchased it. Great power and not too heavy. Only issue is it is too hard to hold down the two buttons top and bottom to keep the unit working. An on and off switch would be great - from my viewpoint. And of course the eternal problem of the advancing the string. But I have an acre and a third and have used this unit for 6 hours in a row and it does the job.

I went looking for electric trimmers because the vibration of my gas trimmer was a problem for me. The Greenworks 21142 was the largest diameter offered.

It has met my expectation of being as effective as my gas trimmer with less damage to my joints.

However as noted in other reviews, the trigger design is unacceptable. My analysis is that the holding force of both actuators is too stiff.

Some hysteresis would help (resulting in a safe actuation force transitioning to a lower holding force).
