Questions and answers

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.

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.

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...

An excellent line trimmer. More power than many petrol powered line trimmers. I've lent mine to my wonderful neighbours on 2 occasions. I understand they ordered one of their own today. A good investment.

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.

My previous line trimmer had 'given up the ghost' so decided to buy this GreenWorks Line Trimmer. This one is so much better and wished I'd bought it before I purchased my previous one. AAA+

Surprisingly Powerful

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.

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.

Excellent Grass Trimming Tool

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.

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.

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

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.

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

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?

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.

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.
