Does this take a specialty line? if "yes" are u the only stockist within NZ ?
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.

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

Hi, how long does the battery actually last when being used. Thank you.
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.

Can you use any of the brush cutter fittings sold here on this unit?
No this is only intended as a line trimmer.

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
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!

Greenworks Line Trimmer G-MAX 40V Li-Ion Skin

Cuts way better and copes well with long paddock grass, compared with my 20v single strand cutter. Fairly heavy, so one charge is enough for the day

Good option

I looked at a number of options for my first ever electric trimmer and in the end on the advice of my brother opted for this one. Bought a mower at the same time on the same advice. The instructions aren’t 100% clear on some things however it didn’t take long to use some common sense and get it sorted. easy to clean and store, not as good in my opinion as a good petrol one but for a home section does the job. Would recommend a second battery for medium/large lawns especially if you’re using a mower at the same time.

Great trimmer

Received this as a package deal with a mower. Was very easy to assemble thanks to clear instructions. Heaps of power and good quality line that easily cuts through weeds etc. easy clean. Highly recommended.

Great for all gardens

Received this free as part of a promotion and I would paid for one if I didn’t. So simple to swap the battery between machines and lasts with plenty of power to both line trim and mow

A beast!

This 40v G-max line trimmer is very powerful for a battery trimmer. It has not hesitated once to chew through long grasses around the edge of my property. The runtime is great and I would recommend to anyone.

does a good job, but definitely needs a harness due to length of trimmer.
