Specs
Question Ranking
Pros
Pro Great value for its price
Priced below $50, this string trimmer is one of the most affordable units available on the market. If offers great value, since the powerful 6.5 A motor makes it a very good choice for all domestic trimming and edging tasks you might need to do.
Pro Powerful enough for everyday, domestic use
The trimmer features a quite powerful 6.5 A motor that does a great job cutting grass and weeds. There shouldn’t be any problems when trimming overgrown grass and even light weeds.
Pro Perfect for trimming near walls
The front-mounted wheel of this trimmer can become in handy when cutting near walls, so you don’t bump your trimmer into them.
Pro Can be used as an edger
Besides being a standard trimmer, it can be used as an edging tool. Just rotate the head, and you are ready to edge your driveway. The front-mounted wheel will help you move along and make a straight line.
Pro Electric engine means easy maintenance
You don’t need to worry about oil changes, dirty air filter, and gasoline. All you need is a solid 110V AC mains power outlet and an extension cord.
Pro No hassle with line changing
Since it is a single-line trimmer, it is easier to wind in the line without any unnecessary tangles that can happen with dual line trimmers.
Pro Feeds the line automatically
The line feeds itself, depending on resistance felt, as you trim along. It is worth noting that the line needs to be winded tightly for this to work.
Pro A very wide cutting path
The trimmer has a 14 inch wide cutting path, which is one of the largest available in this price range. This saves time as fewer trimmer swings are required to get the job done.
Pro Work in a comfortable position
The shaft and handle can be adjusted, so you can do all your work while holding it in a comfortable position.
Pro Perfect for small jobs
This trimmer has enough power to do pretty much every small domestic job you might come across. Additionally, this trimmer has a short yet precise string perfectly suited for small-sized jobs.
Pro Extremely light
This string trimmer is, in fact, one of the lightest trimmers available on the market. It weighs only 5.2 pounds, meaning that it's easy to carry around by pretty much anyone.
Pro Can be used as an edger
If you rotate this unit's shaft, you can convert this trimmer into an edger, so you can finish your garden work by straightening the grass at the sidewalk. While the edging function works well, it does take some time to become used to it, as no wheel supports the trimmer while you are doing the job.
Cons
Con Probably requires an extension cord
Since this is a corded trimmer, you need an extension cable pulled through the garden. Sometimes it can tangle up or get in the way, something that wouldn’t happen with a battery operated or gas trimmer.
Con Consumes a lot of lines
The trimmer uses a thin 0.065" line that can be consumed rather quickly. It can empty in about 30 minutes of extensive trimming. A new spool costs around $8.
Con The motor can overheat quickly
Just make sure to be careful and don’t jam the string, because the powerful motor can quickly overheat.
Con Has only one string
One string trimmers cut slower and can’t handle harsher trimming tasks as efficiently as two string trimmers.
Con Could be more comfortable for edging
You may have to lean forward while edging, especially if you are a tall person.
Con Feels plasticky and flimsy
The trimmer doesn’t feel as sturdy or reliable as more expensive trimmers.
Con Power settings are fixed
There is no way to change the power level of the trimmer, so you’re stuck with maximum power. While most of the time that is okay, sometimes you need less power when trimming near walls and fences ,to save the trimming line, or near flowers, to avoid cutting them.
Con May need an extension cord
Keep in mind that this unit is a corded, so you may need to provide a long enough extension cord to cover places you need to trim.
Con Unusual string release mechanism may be difficult to get used to
While most of the trimmers release the string either based on the resistance or releasing it when you bump the head against the ground, GreenWorks have decided to do it differently. The trimmer releases the string when you release the power trigger. For some, it may be hard to get used to this system.
Con Not meant for tall people
If you are taller than 6', it can be tiresome for you to use this trimmer for long periods of time, due to its size.
