FAQs

What is the difference between auto-feed and bump and feed string trimmers?
Auto-feed string trimmers use centrifugal force to release trimmer line. Each time the unit is activated, the spinning of the trimmer head exerts a force that unlocks the trimmer spool, allowing line to be released. A spring-loaded mechanism relocks the line after approximately 0.25” of line has been release. Therefore, every trigger pull will release line. Bump feed/ bump and feed string trimmers work with a similar mechanism, but the spool lock is manual disengaged by the user by “bumping” the trimmer head on the ground while the unit is in use. This mechanism provides operators with more control over how much line is used.
What attachments are compatible with my string trimmer?
For attachment capable string trimmers, the following brands are compatible: Poulan Pro, Ryobi-Expand-it and Trimmer plus. If you are unsure if you have an attachment capable string trimmer unit, please contact us at 1-888-90-WORKS
Why does my trimmer line keep breaking during use?
Trimmer line will break off during use which is a normal occurrence. In harsher terrain or when used to edge, the string trimmer's line will break off more often as it makes contact with hard surfaces. To reduce line breakage here are some tips: • Keep the underside of the trimmer head/guard area clean of debris. • Ensure that the cutting blade is clean/clear, and the blade is exposed and shard enough to trim the line. This will also help to reduce excessive line breakage. • Avoid direct contact with hard surface areas when using the string trimmer. • In thicker, denser, and longer grass, you may want to go slower. Listen to the sound of the string trimmer, if it reduces speeds, or slows down too much, back away from the grass and start again at a slower pace.
Can I remove the guard from my string trimmer?
No, string trimmers should never be operated without a guard. The guard is a safety feature and helps reduce debris such as grass clippings from being picked up and flung towards the user. It also has a cutting bar on it to prevent line from overextending and breaking off at large lengths. Operating without a guard will cause the string trimmer to work harder than it must and will reduce the life span of the motor. It will also void the warranty.
Why does my line keep unraveling?
Line unraveling can be caused by winding the spool line the wrong way or simply not winding it tight enough. Please make sure you follow the guide inside your owner’s manual thoroughly as this process may take some time to correctly achieve.
What does reduced gear mean for my string trimmer?
A string trimmer that has a reduced gear motor does not directly drive the trimmer head. Instead, the motor drives a larger gear that is attached to the trimmer head. This reduces the speed of rotation but increases the torque. It allows a smaller, lighter motor to produce extra torque and perform tasks more efficiently, while ensuring that the unit is easy to maneuver.
Does my unit come with trimmer line?
Yes, all Greenworks string trimmers come with spool and line that has already been installed in your unit.
Can I use a thicker diameter line than what is recommended?
No, we do not advise using a thicker diameter line than what is advised in your owner’s manual. The use of a thicker line may result in over working the motor and could potentially damage the motor resulting in shorter life span of the unit. This will also void your warranty.
Can I buy replacement line locally?
Yes, you can use any generic brand of trimmer line to rewind your existing spool. Please refer to your owner’s manual to ensure you purchase the correct diameter of line for your unit.
Can I change the original trimmer head?
No, we do not offer this feature currently. However, we do offer attachment capable string trimmer units that can be used with a variety of different attachments from the following brands: Poulan Pro, Ryobi Expand-It and Trimmer Plus.

Works great with bush clearing blade.

Intentionally bought this to work with universal attachments. Easy quiet and powerful. This is my second string trimmer from Greenworks. Run time on the dedicated string trimmer is longer than on the interchangeable model but it seems like the power is better on the interchangeable model. Works beautifully with a bush clearing blade.

Powerful and Reliable but........

I bought this exact combo a couple of years ago and am pleased with the performance. What confounds and annoys me about this unit is the cumbersome process to re-load line onto the trimmer head. Why doesn't Greenworks offer a Quick Wind Head for this unit like the do for the 60V unit. If they do make such an upgrade it is well hidden on their website. Because of this issue I'll be abandoning my Greenworks 80V string trimmer for a competitors model which offers both a manual and a powerload feature that does not require disassembly of the trimmer head. I also have a Greenworks 80V blower and an 80V pole saw which I'm happy with so at least I'll still have a use for the battery.

Maybe the best electric trimmer built but with one fatal flaw

It's pretty well built well balanced. However it's unusable by all but the casual ocassional use because there is a 3-4 second delay between pressing the throttle and the head spinning full speed. This is a prohibitive setup and makes efficiency and any semblance of productivity all but impossible. If they would fix that ONE problem I would buy THREE of them. I own the 80V mower and 80V Pro Blower and love both of them.

Great entry to the Greenworks world.

I needed to clear a hillside behind my house of brush. I used this unit with a RYOBI Expand-It 8 in. Brush-Cutter Trimmer Attachment. The combination was perfect. The 80v brushless motor works effortlessly for a long time with even just the 2.0 Ah battery. It’s comfortable and easy to use. Highly recommend. I used this unit as a test for the Greenworks 80V system. I’ve been impressed enough that I’ve added a chainsaw which also impressed. Now I’m waiting on the inverter (for car camping) and a blower. All use the same battery.

Durable Compatible Flexible!

Picked this Greenworks up two months ago now I can use the Battery from my Greenworks Snowblower in the summer too without paying for a separate battery. Well balanced with shoulder strap tethered near controls motor and battery compartment for maximum reach of each tool's business end. Compatible - I loaned out my Ryobi plug-in last season and lost a few parts of it to neglect. Great to be able to step to no cords keep using existing tools and the power of this 80V system eases through everything I've thrown at it. Brushless and build quality seems good. Should last many seasons as has the Greenworks Snowblower so far.

Poor customer service

I own a couple of their products along with four 80V batteries--pleased but... Went to buy this trimmer but a little concerned because of negative reviews. To get answers to questions one has to send email and hope someone eventually responds. If not sufficent when you eventually get reply it is impossible to get through via tel (hung up after 31 min wait) Really simple Qs. Not covered in video... Weeds won't wait: must buy another brand.

Love love love this trimmer

Easy to use and no gas! Battery last long and trimmer has more than enough power. I bought the 80v version so my blower trimmer and my next purchase lawn mower can use the same battery. Big fan.

Another great tool by Greenworks

After using the 80V snowblower for a couple seasons I decided to get the string trimmer and chainsaw. The string trimmer is awesome as are my other 2 Green works tools. I love not having to mix gas pull a cord until the trimmer decides it wants to start not hearing the incessant whine from a noisy gas engine and being able to hang the tool up for the winter without any extra steps.Having extra batteries is very handy. I have a 2 acre yard with quite a few trees and edging. I can still usually finish the job on 1 battery but on occasion need a backup. I bought the chainsaw without a battery and charger so I only have 2 batteries but that's more than enough for any of the jobs I need to do.No complaint about this or my other Green works tools. Professional durability and power at a consumer friendly price!

Amazing String Trimmer

I have had the 80V cordless string trimmer for about a year now and it is definitely worth the price. I can take care of my 3 acres in almost half the time though I do recommend having at least 2 batteries I have 3 total. The only downside is that the push feed on the trimmer head finally broke and I can't seem to find one easily accessible that works with it.

Solid machine easy to assemble

My 4 stroke gas string trimmer started to act up. So I explored this product. I currently have 80V mower snow blower leaf blower. and hedge trimmer. Strong power easy to assemble sturdy construction quieter than gas trimmer and interchangeable attachment capable. Only complaints are squeeky noise and weight. My gas trimmer is 17 pounds. The Greenworks with battery is 20 pounds. Greenworks used all aluminum and plastic so only place to save eventually is battery weight (2.8 pounds). I highly recommend this product. No need to buy gas. Product is half the price of premium gas trimmer.

Great Replacement for Stihl Trimmer

If you are on the fence about it switching to electric... do it. After a few uses has already proven how much better it is than my old gas Stihl trimmer. Charged it out the box in under 30 minutes was able to do my entire 1/3 acre yard with plenty of charge to spare. So much quieter so much so that i thought it wouldn't cut through the wisteria that grows on my fence. My old stihl would stall but this went right through it without any problems. This is a sleeping giant with plenty of electric torque to boot that will shred through things my gas trimmer couldn't. So blown away. I'm glad I went with this model at 80v. Wish this was around sooner but so glad I found it. Not to mention how light it is in comparison. This is a no brainer folks. Make the switch.

I'm a very satisfied customer

I'd like to begin by saying that the pre-purchase customer service I received was outstanding. I had some confusion about which model suited me best and with help got exactly what I needed. The trimmer works great and my brush cutter attachment fits like a glove. I will eventually be replacing all my 2-cycle tools with 80v Greenworks units.

Great hardware made useless by a nerd.

The trimmer would be great if the bean counters had left the hardware alone to do it's job instead of neutering it down with software beyond the point of annoyance straight to the point of uselessness. I've had it for a week or two and I've only been able to use it once because the motor startup sequence in the speed control is so pathetic it will not even START! Just sluffs some effort for a couple seconds... beeps and gives up. To use my pruning attachment that I have used with a half-dozen string trimmer heads over the years without issue I have to literally shove the chain across something while pulling the trigger on this 80v p o s in order to make it start with about a 60% success rate. My 40v greenworks string trimmer head zips the same pruning attachment right to life instantly so does my ryobi 40v trimmer head my old 2 stroke craftsman trimmer before it the 4 stroke ryobi before it and the 2 stroke ryobi before it! Somebody needs to get ahold of the genius in the software department and let the USER decide how much power they want their device to output. Luckily there's a nifty input device already in place for this.... the TRIGGER! Great hardware and battery tech made useless by a few keystrokes.That is all.

Lots of power

I previously had a 24v string trimmer from another manufacture but it was having trouble keeping-up with some of the thicker grass and weeds at my new house. I had already purchased other Greenworks products so thought I would give the 80v string trimmer a try. This trimmer works great and crewed through the thicket weeds and grass that I could throw at it. Having used gasoline trimmers in the past I can say for a fact that this product can stand-up to them no problem.
