6.0-Ah li-ion battery

The 21602 can be powered by a 6.0-Ah battery (included) or a lighter-weight 2.6-Ah battery (sold separately).

Fast, Easy Trimming and Edging
With the 21602 String Trimmer, yard work is easier and more efficient. This user-friendly tool transitions from trimming to edging with one push of the "Rotate to Edge" button, so it's a snap to shift back and forth from trimming to edging along curbs and driveways.

User-Friendly Features
To save you time, an auto line advancement system replenishes worn line as needed. And thanks to the telescoping shaft, which adjusts to accommodate your height, you won't have to strain to trim or edge.

At just 7.5 pounds, the 21602 is also easy to handle and hold, making it a great choice for all-day jobs.
No Carbon Footprint
No Emissions--Ever
Like all Greenworks lawn products, the 21602 will never release an ounce of carbon emissions into the air. And because it's powered by a lithium-ion battery, this pole saw won't create the mess and potential danger of gasoline spills. This design is also efficient--you'll never have to haul your gas can to the filling station or schedule tune ups and maintenance.

The Lithium-Ion Advantage
The 21602 can be powered by a 6.0-Ah lithium-ion battery (included) or a 2.6-Ah lithium-ion battery (a light-weight option--not included). The included battery is compatible with all Greenworks lithium-ion products, and it provides up to 45 minutes of use per charge--up to three times longer runtime than comparable nickel-cadmium batteries and up to 2,000 cycles. This long-lasting battery also maintains consistent power, so you won't be disturbed by power lapses or surges. And because lithium-ion batteries are recyclable and are manufactured without heavy metals.
Energy Star
Charger Reduces Energy Usage by 35 Percent
Thanks to the wall-mountable charger, the 21602's battery charges to full power in 4.5 hours. Best of all, the charger is Energy Star rated, which means it has been shown by the EPA to reduce energy usage by an average of 35 percent from conventional yard tools. Plus, you can charge the battery any time without any negative memory effect.
4 YR Warranty
Warranty Information
The 21602 is backed by a four-year warranty--that's double the industry standard. Additionally, the battery carries a one-year warranty against defects in workmanship and materials.


Greenworks: Tools for Life
It's time to move beyond clumsy and harmful gas-powered mowers, trimmers, and blowers. With Greenworks' lawn products, you can create no-impact, beautiful yards without sacrificing power, performance, or usability. The Greenworks Lithium System of Tools means you can stop pulling cords, stop filling gas cans, and stop harming the environment. And because all Greenworks charging systems have received the Environmental Protection Agency's Energy Star approval rating, you can be sure that every Greenworks tool is a smart choice for your yard.

I wanted to replace my Homelite 14" dual-line string trimmer as I finally had enough of the noise, pollution, starting issues, mixing/storing of gas & oil, engine maintenance, and the constant need (and effort) to replace the pre-cut line strips.

Cordless is the way to go. However, given the current limitations of battery technology, I was concerned about finding a string trimmer that had the necessary balance of power, run time, weight, and charge time. I also wanted a reliable unit that would give me years of trouble-free service.

I did my usual due-diligence, and spent hours reading reviews and handling a few units at the local hardware stores. I work in the computer/electronics field, so I am very familiar with battery technology and the other parts of a string trimmer. I know I wanted Lithium Ion batteries with >30 minutes run time. I was also more interested in the highest AH (Amp Hour) rating than Volts (e.g., 18V, 20V, 36V, etc). Marketing is pushing the voltage rating (largely because the lower-cost Ni-cad batteries have a lower Amp-Hour rating in comparison to Lithium Ion batteries of the same weight). However, voltage is a poor indicator of how powerful and long the trimmer will run. For example; both a tiny hearing-aid battery and D-size flashlight battery have the same voltage rating (1.5V), however the D-size battery has a much higher Amp-Hour rating. If you replaced the D cell in a flash light with the tiny hearing-aid battery, the light would barely be visible and would drain the battery in less than a minute. Whereas the D cell would light the lamp at full brightness for over 30 minutes. Same basic principle applies to a trimmer. Choices as of now (2010) for Li-Ion batteries range from 1.3 Ah to 6.0 Ah. 6 Ah is a huge amount of capacity! 1.3 Ah is small, and given the amount of current (Amps) required each minute to spin a string-trimmer motor powerful enough to cut grass, is only suitable for a postage-stamp sized yards.

For comparison; as of 2011, a hi-capacity laptop Li-Ion battery is ~ 4.5 Ah.

In addition, Li-Ion batteries do not have the memory effect that NiCad batteries do, so I do not have to totally discharge the battery before recharging. That is a major weakness for Ni-Cads because you always end up charging the battery for the full 12+ hours before each use. Furthermore, Li-Ion batteries hold their charge over a much longer period of time than a Ni-Cad. I can fully charge a Li-Ion battery and, a week or so later, top it off with a quick charge (say 90 minutes) as required over the season.

Unfortunately high Amp-Hour Li-Ion string-trimmer choices are very limited at this time. The Greenworks 21602 and Troy-Bilt TB57 are really the only choices; the TB57 being the cheaper of the two. They are basically the same unit. They both use the identical Li-Ion 6AH battery and 4 ˝ hr. charger. The only real difference (other than color) is the shaft, throttle switch, and the swivel hinge for edging on the Greenworks. BTW: you could buy the TB57 and use the battery on the Greenworks leaf blower. I handled the TB57 at Lowes, and I agree with the negative reviews about the short shaft and force required to hold the safety switch in.

In the end, I ordered the Greenworks mainly because I am 6' tall and the TB57 was just a little short (even with the telescopic shaft at maximum) and I know my finger would get numb from holding the power switch down.

I really struggled with the decision to buy this particular brand of string trimmer. I was hesitant to buy an unknown brand; especially since the Greenworks web site did not list any near-by service locations to drop the unit off for warranty repair (only option is mail in), and reading two reviews on Amazon where the warranty hot line was non-existent or unresponsive. That makes Greenwork's four-year warranty worthless. I am also concerned about the longevity of the electric motor. Will it last +5 years? I noticed two people already experienced early-life motor failures (one Greenworks and one Troy Bilt). I plan on giving the Greenworks a good workout and return it to Amazon if I find anything I don't like during the first 30 days.

Well I got the Greenworks four days after ordering it (selected the free shipping option) from Amazon (exceeding my expectation and one of the main reasons why I buy from Amazon).

Assembly was very easy (needed a Philips screw driver for the one screw). Build quality seems good. I do agree with one reviewer that the plastic handle feels a little cheap as it flexes a bit. However, that flex does make the unit even more comfortable. The shaft is long enough for me. The balance and weight are very good.

Regarding cutting power; this is not a commercial grade trimmer that you use for a landscaping business. The power is sufficient to cut through dense grass; however I have to move a little slower than I did with my gas trimmer. This trimmer is suited for yards that have been maintained well in the past. I would not recommend it for a yard that is, or often becomes, overgrown (i.e., grass or weeds over 12" tall).

The automatic line feed works very well. Each time I start the unit it feeds Ľ" of new line. The only drawback is that I go through a lot of line when I move from tree to tree; stopping the unit each time to save battery power. The four hour charge time is adequate as it does keep me from missing a scheduled grass cutting if I forget to charge the battery the day before (can't do that with a 12 hr. Ni-cad charger). Like any battery powered trimmer, the noise level is very low. I am now able to trim the yard in the early morning (before I start using the lawn mower) without getting my neighbors upset. So far I am satisfied with this purchase.

However, I did notice the motor slow down to about 1/3 the speed while using it. The speed returned to normal when I released the throttle and pressed it in again. This happened three times already. I am not sure if the motor has a built in thermal power reduction (which is good as it would prevent the motor from burning up). If it starts to happen more often, I will return the trimmer to Amazon.

Update week 1:
Battery life is excellent. I have used this trimmer over a five day period on the original charge. After +30 minutes of use, I still have three of four battery status lights on.

I have noticed that the motor air vents clog with grass clippings after a few minutes of use. This may contribute to the motor overheating/failure problems some are experiencing. I now make it a practice to clean the air vents (wipe off the external grass and blow out the grass inside the motor) every few minutes. I think Greenworks should design a thick foam ring that fits over the motor to trap the clippings. Then all I would need to do is periodically rinse the foam ring in soapy water.

Update week 3:
After 3 weeks of use, I am very pleased with this trimmer. It took awhile to get use to the fact that it is always ready to go with just a push of a button; no need to charge before each use, no worries bout prepping the motor and trying to start it, etc. I now find myself pulling out the trimmer when I come from work and spot a few weeds while walking along the driveway or sidewalk. The battery status bar finally dropped down to 2 of 4 lights; so I charged it up to give the battery charger one more test before the 30 day exchange period with Amazon ends.

I have not experienced any more slow downs. I suspect that was caused by clogged air vents.

I used the edger for the first time last week; just pushed the big button on the shaft near the motor and the shaft pivots 90 degrees. The wheel rolled smoothly and the angle of the shaft was perfect as it gave me a good view of the cut. It was much easier than I thought and produced consistent results; far better than the free-hand edging method I have been using for years.

I have already used all the string on the one spool and inserted the free second spool (BTW - easy to change). I went to Home Depot and purchased a 300' re-fill package of the .65 blue line to re-fill the spools as needed. For ~ $7, I have enough line for years.

However, the real shining star is not the trimmer, but the 6AH Lithium-Ion battery. The capacity is perfect for all but mega-size yards.

I received the Greenworks 24602 blower for Father's Day; it uses the 20V/6AH Li-Ion battery from the trimmer. Now I can trim the yard and use the blower to clear off the grass clippings from the driveway and sidewalks. The blower with this battery makes it very convenient to use and makes it more versatile. For example, I used it to blow dry my car after I washed it (beats ringing out drying clothes). I also opened the car doors and blew out some dog hair and dust from inside the car.

I would buy the Greenworks chainsaw (also uses the same battery) to cut up the many small limbs that blow down after a storm. Unfortunately, the current $69 10-inch chainsaw is too expensive and large for what I need. A 6-8 inch model (with a lower cost) would be ideal to cut up limbs and small tree shoots into small enough pieces to toss them in a trash can.

Bottom line: "It's the battery stupid" (I think that's a Bill Clinton quote); the fully capable string trimmers (either the Greenworks or Troy-Bilt) and leaf blower only exist because of it.

A dream! April 15, 2010
By Mary
Amazon Verified Purchase
I was waiting to see whether anyone reviewed this new trimmer before buying it, but decided I couldn't wait any longer and took the plunge. It replaced a terrible corded trimmer that I had to take apart every few minutes to fix the string. The Greenworks with Lithium Ion battery works beautifully. The battery was still at fairly high capacity after about 45 minutes of trimming. Out of the box, the trimmer makes a good impression. It's solidly built. The instruction manual isn't very good (lots of repetition in the safety warnings and poorly written assembly instructions), but assembly and operation were easy to figure out anyway. I was concerned that the trimmer would feel heavy with the battery attached, but that wasn't a problem at all. Switching from trimming to edging is a snap. I love the automatic advancement of the string (especially after my old nightmare of a trimmer). The manual warns the user to keep an eye on the string after turning off to make sure that it hasn't receded too far, but so far that hasn't been a problem. I was worried that the trimmer wouldn't seem very powerful, but it had plenty of power for my needs. I have a large garden with a lot of edges to trim. No problem with the Greenworks!

Four months later (August 2010) and I still love it. I just ran out of the string on the first spool. Changing it was easy. I dropped the battery on the hard pavement and was worried I had ruined it, but there seems to be no problem--I just spent 45 minutes edging my garden and the battery still works great. I also bought the blower that uses the same battery--another great purchase!

Smoked and Cured May 26, 2010
By Wordboy
Amazon Verified Purchase
I unpacked and assembled the weed trimmer the same day it arrived. Easily done. During the first and only time I was able to use it, the weed trimmer began to smoke in less than 20 minutes of use. I let it cool off and tried again. It wouldn't run more than about 10 seconds so I gave up.

The manual says not to use the machine if it smokes. The manual has only a phone number to use to contact Greenworks. There is no mailing address, fax number or email address. I called the Greenworks number to talk about the warranty. After a 12 minute hold, I told a person about the problem. I was told that someone would call me within an hour for a "resolution." After two days without a call from Greenworks, I called again. This time I was on hold for 15 minutes when I gave up. I never heard from Greenworks after my first call. I then used the order confirmation email from Amazon to contact Amazon by email about the problem. That same day Amazon sent a new weed trimmer by overnight mail, even though I only paid for the lowest cost delivery on the original order. Amazon gave me about 30 days to return the old weed trimmer or I would have been charged for the replacement weed trimmer. My conclusion is that the warranty by Greenworks is worthless but Amazon stands behind the product.

I haven't had any problem with the replacement weed trimmer. It has almost as much power as a gas trimmer, as other reviewers said. I used it on thick grass under my wrought iron fence where the grass was about 10 inches high. It worked well. So far, I used it about an hour and still had about 25% charge remaining in the battery. The second time I used it there was 50% charge remaining after about 45 minutes. I am pleased with its performance. The battery charged in about two hours when it had 25% charge remaining. The battery moves easily from the charger to the weed trimmer.

I'm going to give it five stars because of its performance, including that of Amazon. If Amazon had not sent a replacement so quickly, I would have given it one star.
