The head is fixed, but can the buttons still be comfortably operated when it is flipped over so it cuts in the vertical plane ?
Yes they can. The auxiliary handle on the middle of the shaft has been ergonomically designed to make this easy and efficient.

Greenworks Line Trimmer

Great little trimmer--light to use-easy line install--

Jonesze Auckland

I believe that this trimmer is one of the best things that i have brought. So light and easy to use

kev West Coast
Green machine

What a great machine! Far easier to use than my heavy petrol machine. Cutting power at least if not better, much more manoeuvrable and no starting issues. Cut grass at least 350mm high without trouble. Overall a great line trimmer.

I have a few green work 40 volt battery tools and they're all robust and do what they say they'll do. Not professional quality but a step above consumer brands in my opinion. This weed eater seems same quality and bit more powerful than a lot of the other ones on the market which means you do the job in half the time. The battery is shipped separately because it's a dangerous good which caused confusion.

Great little machine

Cuts through most grass, makes a great edger, and easy to assemble. The line that comes with it can get stuck but easy enough to fix.

Loosh Auckland
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

Leighton Marton
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.

Andrew Auckland
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.

Kotter Auckland
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
