Q: Hi Todd,
I wonder if the Greenworks String Trimmer 21072 comes with a battery included? (I read that the charger is included.) What can you tell me?
Thnak you,
Ron from Michigan

by Ron Norton from Michigan on July 17, 2011

A: Ron - yes, the Greenworks 21072 string trimmer includes a 20-volt lithium ion battery and the charger.
by Todd, Product Expert

Q: Can the Greenworks 20V lithium-ion string trimmer use either the 2.6 Ah 20 V Greenworks lithium-ion battery or the 6.0 Ah Greenworks lithium-ion battery?

If so, what is the approximate run time with the 6.0 Ah battery?

Also, can I purchase from you the string trimmer alone (i.e., without battery or battery charger), and if so, what is your catalog number for that, and what is your price on it?

(I recently purchased from you a Greenworks 20V lithium-ion hedge trimmer with 2 ea 6.0 Ah batteries and 1 ea battery charger, so I don't necessarily need to buy more than the string trimmer itself.)

by Bob Cohen from Colorado on July 16, 2011

A: Bob - the Greenworks 21072 comes with a 2.6 Ah 20-volt lithium ion battery and charger. And yes, you can upgrade the battery on this string trimmer to the 6.0 Ah lithium ion battery if you want to.

The 2.6ah battery runs about 35-45 minutes depending on conditions it is used under. The 6.0ah battery will run 55-65 minutes depending on conditions. So while there is a difference in run time, it is not that significant.

Greenworks does not offer a 20-volt lithium ion string trimmer without the battery and charger as an option. They do have a blower and a hedge trimmer that can be purchased without the battery and charger, but not a string trimmer.



by Todd, Product Expert

Q: If I order the lithium ion 20V battery for my greenworks cordless hedge trimmer does a charger come with it or do I need to order that seperately?
by Bryan Stauffer from Washington on July 03, 2011

A: Bryan - you would need to order a new charger separately. The charger is not included when you order a new battery.
by Todd, Product Expert

Q: Does this trimmer come with a charger for battery? Tx
by Roberta Miller from New York on June 28, 2011

A: Roberta - yes, this trimmer includes a charger that will fully charge the battery in approx. 4-1/2 hours.
by Todd, Product Expert

Q: Does the charger stop charging on its own or does the battery have to be removed as soon as charged?
by Patricia Wills from Wisconsin on June 18, 2011

A: Patricia - the battery charger will stop charging the battery on it's own once the battery is fully charged. The battery may be stored in the charger or removed once it is fully charged. It is recommended that you unplug the charger from the electrical outlet once the battery is fully charged if you store the battery in the charger.
by Todd, Product Expert

Q: If we can't locate the replacement string locally, can we order it online? Also, I didn't locate it on your site.
by Rebecca Kennemur from Georgia on May 30, 2011

A: Rebecca - this trimmer uses standard .065 diameter replacement line. You do not need Greenworks brand replacement line. This should be available at any hardware store. We also carry this replacement line, so you can order from us if you wish to do so. Trimmer Line
by Todd, Product Expert

Q: Will a 18V, 20V or 24V enter changeable or not. If so what the differ beside the time and what will happen
by F. Gilmore from North Carolina on May 05, 2011

A: No, you cannot interchange different voltage batteries on any of the cordless hand held lawn tools. You also can't interchange lithium ion and Ni-Cad batteries. This 20-volt model will only operate off of a 20-volt lithium ion battery platform.
by Todd, Product Expert

Q: Howdy from snowy Montana. I gather this doesn't come with the battery charger? What lithium cordless grass trimmers do you have that come with the charger? Thanks, Heidi
by Heidi from Montana on April 30, 2011

A: Heidi - actually, the Greenworks 21072 does come with a battery charger, which can be wall mounted if you want. All of the lithium ion cordless string trimmers that we carry on our web store include the battery charger.

Todd's Recommendation

The GreenWorks 21072 cordless electric string trimmer is a great choice if you want to maintain your lawn while doing something good for the environment at the same time.

The Greenworks 21072 is powered by a 20-volt lithium ion battery. If you’re not familiar with lithium ion power, it has two HUGE advantages. First off, a lithium ion battery is considerably lighter in weight than either lead acid or Ni-cad batteries. So your string trimmer weighs a lot less and it’s easier to handle. Second, lithium ion batteries maintain their full power for the entire run time cycle of the charge. This string trimmer will run at full power for the entire charge of the battery – no fall off in power as the battery runs out of juice!

The Greenworks 21072 runs for up to 45 minutes on a full charge. And because it’s cordless, no dragging that extension cord all around your yard. You can take this string trimmer anywhere your legs can carry you and tame that tall grass and those pesky weeds.

The Greenworks 21072 cuts a 12-inch path, and the automatic line advancement system replenishes worn line as needed. Use the "Rotate to Edge" button to make a quick and easy switch to edging. And the telescoping shaft adjusts to accommodate your height.

Best of all, the Greenworks 21072 comes with an industry-leading 4-year manufacturer's warranty.

Works Great

I used my new Greenworks 20-volt string trimmer yesterday for the first time, and it works exactly as advertised. Very easy to assemble - less than five minutes and all I needed was a phillips screwdriver. String trimmer created a surprising amount of power. I used it for about 20 minutes to trim my entire yard, and the lithium ion battery did just what it was supposed to. The power on the unit never diminished the entire time I used it. Ran just as fast after 20 minutes as it did when I started trimming. I'm very happy with my new trimmer.

I enjoy using the Greenworks trimmer. It's everything that it was claimed to be by others who rated it. I've used B & D trimmers for years the and the battery lasts much longer in the Greenworks than the B & D battery. I would definitely recommend the Greenworks as a superior trimmer. It certainly meets my needs ( an eighty year old man) for a lightweight trimmer, that I use to trim a three acre well landscaped lot.

Great Single Line Trimmer

I recently purchase this trimmer after failures with a number of gas trimmers, and the battery life and automatic line problems of electric trimmers. I have found this trimmer to be very light and powerful with a battery life that allows me to trim my yard, flower beds and both sides of a 90 ft driveway on 75% of the battery's charge. I have a yard that is 76 x 90 in the front and 120 x 76 in the back. There are side walls on the property that are trimmed, so you can see this unit is both long lasting and powerful. Time will tell if the unit will stand up to the work I use it for but so fa... more

Works Great!

After researching all my cordless options. I found this one to have the best reviews. I received it a couple weeks ago, and very pleased that it is everything I expected it to be.

Very nice

Got this to replace a cordless Sears trimmer. The Sears trimmer needed replacement lead acid batteries every 2 to 3 years at about $60. So time to try a different brand and newer technology. We will see how the battery holds up over the years.

Great weed whipper

It does a great job. The only problem is the short battery life. I have to recharge before finishing the job.

Just follow instructions on charging the battery, etc. I personally had no trouble with the operation of the tool! In fact. I trimmed-edged this day. Kudos to the people associated with the product.

The 21072 is FANTASTIC

After researching and going store to store to compare the competition for a good cordless weedeater, I was very disappointed with what was available. I checked the web and found Greenworks and took a chance.

WOW was I surprised the minute I opened the box, quality all the way. It wasn't until I used it that I was convinced that I'd found the best product possible. Now all my neighbors have seen how great it works, and are submitting their orders for one. Great going Greenworks, you guys RULE.........................

Greenworks 20 volt string trimmer

I did heavy duty weed whacking with it the minute I got it which was 3 days after ordering! It's just great! I'm 82 years old and it was easy to use.
