Customer questions

Questions and answers

1 vote
q: Does this take a specialty line? if "yes" are u the only stockist within NZ ?
a: You can re-load the cartridge with any line. The supplied line is 1.65mm, at this stage we are the only stockist of the cartridges pre-loaded with this line.

0 votes
q: Is the cutting line in a pre-loaded spool? How is the line fed out? I have had experience of pre-poaded spools previously and it was not a good one. The line jams in itself and won't feed, thereby breaking off. Thanks for your time
a: Yes it comes on pre-wound cartridges, it uses an auto feed mechanism (no need to tap on the ground). We've yet to see any issues around line jamming. Check out the customer reviews to see how others a getting on with theirs!

q: Hi, how long does the battery actually last when being used. Thank you.
a: Up to approx 40mins, however run time can vary quite a lot depending on the length and density of what you are cutting. Longer, thicker, denser grass and weeds place more load on the motor, draining the battery faster. If you look at our customer reviews below it will give you a better idea of what to expect.

q: Is there an edger attachment, or does the trimmer swivel?
a: There is not extra attachment, the front handle adjusts so it's easier to turn sideways.

q: What other equipment can you use this battery and charger with pl? The pole saw?
a: You can use this battery with any other tool in the Greenworks 40V range - type 'Greenworks' in the search bar at the top of the page to see all available tools.

Good product

Stoked with this trimmer. I have a large section and it gets through a good chunk of the section on one charge. Performs really well!! Great price too compared to other products in the market.

better than expected

This performs around my home just as well as any corded or petrol trimmer I've had. The battery is holding charge well so far (have done complete trim of the property 3 times to date without recharging yet). Its brilliant.

This is an excellent product. Regrettably, I did not have the hand strength to correctly fit the screws that hold the black cowling in place. Consequently, I used this without the cowling and damaged the green circular plastic disc that holds the unit together. (Replacement required)

It's all about the angles

Once I worked out the holding positions and angles for each job, this line trimmer worked great. Fast and had no problem with my kikuyu lawn edges. Quite a workout but not as heavy as my old petrol trimmer.

Leave petrol and go electric

3 months ago


I started with Lawn Mower and find it is great, so decide to leave petrol and go on electric, they are more easier to press a button than to pull start, more quiet plus lighter. will go add on more garden tools to share the battery.

This is the 4th GreenWorks product I have purchased and I am exceptionally pleased with them all.They all outperform any expectations I had for them and I would recommend them ( Line trimmer, Chain Saw,Pole chain saw,Hedge Trimmer) to any person needing garden gear. I am not a professional gardener although I do have a very large section ( about 1 hecter).

Purchased the line trimmer as I already had the electric lawnmower. Plenty of power and so much easier than filling with petrol. The easy starting is another huge advantage.

Ray Wellington

I have a large garden with a sloping grass covered back section which has always been a laborious and time consuming job to keep trimmed. For years I have used an electric line trimmer with a long cable, and all the inconvenience that goes with it. Having recently bought a G MAX lawnmower for the flat area, and being delighted with the efficiency of the machine, I decided to buy a GreenWorks line trimmer for the sloping area. It arrived on time and when I used it (Using the battery from the G MAX lawnmower) it changed the whole process of cutting the grass on the sloping bank. No more long cables. It is a powerful machine with the advantage of a longer than usual shaft which allows long sweeping cuts. It is very economical with line usage. I can now finish the job in half the time taken with the old electric machine. I am absolutely satisfied with it and recommend it to anyone needing to cut grass on a sloping section where the use of a lawnmower is not practical.

Excellent Line trimmer, impressed with the power, and low noise levels. Definitely not going back to petrol!. The 2AH battery is plenty for a medium sized section.

I was pleasantly surprised by the performance of the Greenworks line trimmer. High trimming power and very good battery performance. I'm a taller guy and the layout and length of the handle and shaft made for easy use without any stooping. Great value product.

Works really well

Has heaps of power, works perfectly. Comes with a roll or two of spare trimming line. I purchased a few spare rolls when I got the trimmer, probably didn't need to. The line is thick enough that it doesn't break all the time and the auto lengthening works well.

Works well. Gets the job done and can be stored folded in half. A bonus. Battery is more them ample for multiple uses. Quiet as well. No more extension cords or mixing fuel for the other weed eaters.

Great stuff

On first workout with this line trimmer it was easy peasy. I was a little apprehensive about the auto feed, but this proved to be unfounded as the auto feed worked very well. I'm over 76 years old and found the balance of the trimmer with a couple of adjustments to suit me in short time. Easy to use and trimmed exactly where and how I wanted my edges to look.

Alisam Auckland

I have only used this once. 1) Despite other reviews, I thought this was heavy. More so than I imagined. I am male. 2) I am not sure I have the line fitted correctly. If not it is a dud. But, I don't believe that, (from other reviews) so I will re-check everything. I don't think the instructions are brilliant therefore I have watched some YouTube Videos (they all seem to gloss over the final bit). I'll give this a recommendation, but I am not sure. And the only options are Recommend Yes or No.

Easy to use

I procrastinated over buying a battery weed eater for several months. I looked at quite a few models. I liked the reviews on this and was also informed by friends to get the 40 volt model. I live on a corner and used it to edge the grass/ footpath. Took a while the first time but now takes 10 minutes. Easy to use and charges very quickly. Came with a metal wire cord and need to find where I can get replacement. Definitely recommend.

Plenty of power

9 months ago


After buying an expensive petrol line trimmer but never using it after the first time (having to mix petrol, noisy to use), we thought we would try a battery one that would always be ready to go. We have used it several times already, the strategy worked, it is so convenient. Pleasing amount of power and seems to run a long time...

I have always struggled with weedeaters, petrol spills, don't know how to put the reel line in properly, can't pull start it, flood it, too heavy, hurts my arms... The list goes on But this one is absolutely amazing! Charged up the battery and away I went. So user friendly, automatically fed out new line and is reasonably light weight. I was able to go around the whole over grown lawn, Kikuyu grass and gone to seed weeds that were up over waist height didn't stand a chance.. Was really impressed with the product.

Product works fine, replacement line is the problem

This line trimmer works well however when I went to purchase replacement line from tradetested they could not supply more which seems really poor. Why would you sell a product like this but not stock replacement line?

Reply from Trade Tested

Apologies, we have replacement line arriving very soon.

Bought this as it uses the same battery as the lawn mower. Great trimmer and very powerful. Very balanced and has a bump bar to get it just right. The line it comes with is long lasting and auto feeding. Hard to beat. Love it.

What a brilliant product. Have purchased the GreenWorks Chainsaw, Pole saw and Blower previously and they are fantastic. Going to the battery is certainly easier and easier especially for the smaller jobs although I have used all of them quite hard too.

Servelan Auckland

Surprisingly Powerful

about 1 year ago


I purchased this to replace a petrol model due to environmental concerns, and was not really expecting to have anything as good as the equipment it was replacing. This IS though! I found this to be lighter, easier to manoeuvre and much more powerful. This trimmer was easy to assemble, charge and use and would definitely recommend this to anyone needing a general purpose device. I use this for lawn care (as my lawn is quite small) and edging.

Dane Auckland

Simple and practical

about 1 year ago


It still runs fairly well after I've used most of the battery with the mower. The automatic feed actually works. It feeds when the trigger is pressed, which it quite convenient when you're used to it. If you feel the line getting short, stop and start again. Seems more reliable than bump feeding. Its optimised for right handed use, which I've gotten used to. I can see the benefit of this approach.

Ian Wellington

Working very well

about 1 year ago


With winter being here I have only used this item 3 times but it has been excellent so far. It is very powerful and has been easy to use. So far the line has hardly been used up at all (compared to my last trimmer that used up a lot). Charging is as easy as it should be and quick enough to mean it is always ready for use. I am very happy with it.

Jim Manawatu

Excellent Grass Trimming Tool

about 1 year ago


Works well. 2Ah battery lasts about 20 min & the 4Ah battery about 40 min. The line feed system works well & doesn't waste line. Have now used the trimmer 4 times at an hour each time almost continuously and have not yet got through the first line spool despite having some concrete edging.

Works great, no complaints

Cuts through high grass like a hot knife through butter. Battery life is decent, and with the batteries between it and the GreenWorx lawnmower being exchangeable, the added flexibility comes in handy.

Russell Auckland

Great product. 4Ah battery lasts the whole job when line trimming a 1/2 acre section and there is not excessive line waste.

Nix Wellington

Line trimmer

about 1 year ago


Pretty good product at a good price for a 40V. Lasts around 40 minutes on a full charge, easily enough for a large section. Odd system of line extension - each time it starts, the line extends 5mm. I prefer the bump method. Comes with a spare spool, whih is handy for a quick change.

Cory Auckland

Great unit

about 1 year ago


Really like the trimmer, easy to assemble and run, the line dispenses easily, only hassle is my lawn is quite large so I could do with a bigger battery or at least a spare. For a small to medium lawn you would probably be fine for edge trimming each time on less than a charge
