GreenWorks 21212 review
The GreenWorks 21212 is a corded string trimmer with 4 amp electric motor. With a cutting swath of 13 inches, the motor makes the dual strings cut through thick grass without problems.
What attracts most people to this string trimmer is the price. It is inexpensive, no doubt, and cost just a fraction of high-end trimmers. That was one of the reasons why I acquired this trimmer and I am still pleased with it after a couple of months.
I would say the trimmer is fairly basic, even though you can customize and adjust this string trimmer to fit you in a couple of ways. The telescopic shaft let you increase the length up to an additional foot. This makes the trimmer fit people with different heights. However, be aware that it still can be a bit short for people over 6’4”. You can also adjust the auxiliary handle by rotating it and sliding it up and down the shaft.
Edger and trimmer
Trimming with GreenWorks 21212 is a breeze. It is light and easy to handle, and yet powerful enough to deal with most types of grass and weeds. As expected, the trimmer struggles with thicker stalky weeds. If you need a string trimmer to cut down these kind of though weeds you are better off with a trimmer that uses a thicker string.
The GreenWorks 21212 is well balanced and easy to handle. With a weight of only 4lbs, I dare to call this string trimmer light. The trigger switch cover the whole handle and needs just the right amount of pressure to depress. I am pleasantly surprised how low the vibrations from the trimmer are. No more tingling arms after trimming!
You can easily convert the string trimmer to become an edger. This is done in a few seconds by just rotating the shaft and tightening it. The edger function works all right, but can be a bit tricky since there is not any side wheel to support the trimmer. Nevertheless, by flipping down the metal guard you can prevent the string from hit the ground. The metal guard works well when trimming along edges as well.
Comparison with other trimmers
The GreenWorks 21212 is best suited for a small to medium sized yard. It can handle thick and tall grass without problems, but for the tougher weeds you want something with more power. When I did research for this trimmer, I had a look at GreenWorks’ 21272 and 21142 as well.
The GreenWorks 21272 is a corded trimmer with a slightly more powerful motor (5.5 amp) and a larger cutting swath (15”). This string trimmer is very versatile; you can adjust it in several ways to fit you. If you plan to use your string trimmer as an edger I will recommend you getting this model since it has a side wheel which makes the job a whole lot easier.
The GreenWorks 21142 is also a corded strimmer with a really powerful motor (10 amp) and a large cutting swath (18”). It uses a thicker string and can therefore handle tough stalky weeds. If you were planning to use your string trimmer to clear larger areas that are overgrown with weeds, I would recommend this. Another feature worth mentioning is the Quick Connect Coupler, which allows you to change the trimmer head so you can, for example, use it as a hedge trimmer or an edger.

The string feeding system with this one is a bit different to what I am used. It won’t feed string automatically when the string is worn away and you don’t bump it to get more string. Instead, the string feeding system release about ¼ inch of string each time you let go of the trigger. When the trigger is released for a couple of seconds, the trimmer will advance more string. If you listen carefully, you can hear a click.
Be aware, if you let go of the trigger often this trimmer will eat through a spool with string in no time. I found out the hard way when I used it the first time when I cleaned up along the edges and around objects after mowing the lawn. The result was a trail of small pieces of blue string after me.
The string trimmer uses a 0.065 dual string and spare spools can be bought at various garden centers. Look for the GreenWorks spool with model number 29082. Alternately, you can pick up spools for the HomeLite trimmer with product number AC41RL3 at Home Depot.
