Good riddance to gas whips. I hate them.
Using this on a 1 acre spread. Doe the job and line feed works well.

What a game changer. I used to think trimming was a chore, now I actually enjoy doing it. The tool is quiet, powerful, light, and really does the job.
Plus, the string advance feature works well. 5 stars and thanks to greenworks

Clean & quiet
PORT ANGELES, Wash — I have to hide my chuckles whenever my next-door neighbor trims his lawn.
Chatting over the fence, he has nothing but complaints about his gas-powered string trimmer. He’s glad to have a break from its noise and fumes.
“How’s that Greenworks of yours work?” Dave always asks. “Like a charm” is my response. “Why don’t you buy one?” I counter.
But Dave thinks lawn work must be noisy, smelly, heavy and hard. I, though, am a convert. I ditched my old gas-powered string trimmer after it hung unused for two years while I used my Greenworks machine.
I also had no further use for my fuel can, bottle of fuel stabilizer and quarts of motor oil — not to mention the puddles of oil and gasoline that always managed to evade the funnel when I tried to save the remnants.
My 40-volt, 14-inch G-Max trimmer has met every task I’ve set it to: high grass, dry grass, wet grass, wet and high grass, even those dense knots of turf that have persisted so long even their roots are above ground.
It even cuts most blackberry vines.
That’s with the shield in place. Remove it and, hooboy, I feel like trimming across Dave’s yard and down the block. Just be sure both strands of trimmer line are even. If they are lopsided (without the shield’s cutter to keep them equal), the motor will sense the imbalance and shut off after a few seconds.
Being a neatnick, I clean caked grass and dirt from the trimmer head and shield, just like I’ve always done.
But I don’t spill oil or gas or fill my nostrils with fumes or need ear protection, just like I always used to do.
And I’ll always urge Dave to switch to Greenworks.
My Greenworks trimmer: It’s an always breed of machine.

Great HD Trimmer, similar performance to gas
Brushless motor in a 40V Lithium platform makes for a very powerful and efficient tool. Low and High speeds that are both variable (4070-4800 and 4070-5540 RPM no load, as tested) make it very versatile. Being able to accept various brands of attachments in place of the string trimmer attachment, makes it even more versatile.

Efficient battery usage thanks to the brushless motor … you can get respectable run time even out of the smaller 2.0/2.5Ah batteries if you use LOW speed and vary the trigger speed based on what you are trimming. Max out low or switch to high only when you get into thick stuff that needs it and you will get longer run time.

String trimmer head is the simple feed through design and very robust; the bump feed also works better than the similar brand "X" version. Plus it mounts to the head with a larger 10MM bolt instead of an 8MM that the other brand uses. Anti-wrap shield comes up higher than the other brand too so the likelihood of long grass/weeds getting wrapped up around the shaft above the bump head is as close to impossible as you can get. Bigger defector shield than what the other brand uses is a plus as well.

Only downside is it is a bit heavy … 13.18 lbs. w/ 2.5Ah or 14.22 lbs. w/ 4Ah battery … which is 15% heavier than the lighter duty brand "X" brushed motor equiv. (11.24 lbs. w/ 2.6Ah battery). This Greenworks Trimmer does come with a shoulder strap that helps manage the weight, plus the higher performance, added robustness, and better features far exceed the additional weight.

Bought the "Tool Only" because I already had 3 batteries and 2 chargers.

This is a great item that I can highly recommend to those shopping for a powerful edger trimmer. The 40 battery has a good run life and quickly charges.
This is another Greenworks product that I am happily adding to my collection of Greenworks products.

works well without the hassle of mixing gas
I bought this trimmer because I already had a Poulan string trimmer with attachments.
The attachments I already have fit this trimmer. I have worn out two gas Poulan trimmers on light home use. Though I would give a battery powered trimmer a try.
I already have a green works chainsaw for light tree trimming that works well. Batteries are the same which mean fewer chargers sitting around. have 2.5 and 5 amp hours batteries. 2.5 amp hour battery is plenty for the trimming I do on the 2 acres of lawn I mow. Hopefully this trimmer lasts longer than the 3 to 5 years I get out of Poulan 2 cycle motors.

Berry Shreadiing Machine
I am getting pretty impressive battery life with this machine. I have added the accessory Ryobi brush cutter head which turns a metal brush blade. I had a machinist turn down the blade mount piece to accept a 7.5" carbide Skil saw blade. This is what I have been using on my Sthil gas weed eater for years to clear berries like black berry thickets. I also limb trees with it. I can eat through a lot of Salal (woody berries) and tough blackberries that would wipe out string trimmer string that is unable to cut the woody stems. Its really quiet and fun to use. I get more done with this tool than my old gas tool because it wears me out slower, usually the battery outlasts me, but I have two battery's if I'm up to it. (I am getting old)

It works
Not the fastest trimmer, but it is electric. No gas to get old, no cord to pull, ready to go with the push of the "ON" button. String seems soft and doesn't last long, but I bought another brand from CPO and will reload it when the original runs out. It does a great mob on grass, ok on weeds. The trade-off in power is with it to me.

Will the Ryobi Expand-It brush cutter attachment work with the 2100202?

What does bare tool mean? Does this come with everything I need or is it missing something?
Stu on Aug 21, 2016
BEST ANSWER: Many items come with the required battery and charger. This tool does not. I am able to respond to your question because I recently purchased this "bare tool" (meaning no battery or charger) because I also purchased a mower that came with the G-MAX battery and charger. However, they do sell the battery and charger separate... but, you may find it cheaper as a package.
On the 2100202, what does it mean when the button on right is flashing red and there is a beeping signal?
A shopper on May 10, 2019
BEST ANSWER: The battery maybe defective. You can contact the Greenworks technician at 1-888-909-6757. The agent will be able to assist you with the warranty information.
Will this accept a 40V 2982 battery
Paul Jordan on Aug 19, 2016
BEST ANSWER: 29472 and 29462 are the batteries that this tool accepts.
Will this accept a 40V 2982 battery
Paul Jordan on Aug 19, 2016
BEST ANSWER: Model 2982 does not appear to be a valid model number. Greenworks model numbers are generally 5 digits long.
1. Is model #2100202 the bare tool version of #2100702?
2. What is the difference between Automatic feed and Semi-automatic feed (does this mean bump-feed?)?
ReelDog on Aug 19, 2016
2. Semi-Automatic feed = Bump feed
How do I wind the string on dual feed string trimmer head so it will feed correctly?
