Product overview

This G-MAX 40V Long Reach Hedge Trimmer from Greenworks will make short work of all your overgrown hedges and, with a maximum reach of 2m, you’ll be able to do it all with your feet safely on the ground.

Powered by the interchangeable G-MAX 40V Lithium-ion battery system which delivers longer run time, higher performance and greater output on all G-MAX tools, it has all the power of your old petrol unit without the noise and pollution.

Cushioned over-mould handles and a full loop front switch provide comfort and, when combined with smooth G-MAX 40V power, noise and vibrations are kept incredibly low.

The saw head item seems to have an extension tube. Is the same or similar tube available for the hedge trimmer. If so it would solve a small area that I have difficulty with.t
Unfortunately this is a fixed unit and cannot be extended.

Can you angle this to 90deg to cut the top of the hedge? thanks
The head does angle forward quite far just not to a full 90 degree to the handle, but it is very close to about 110 degres

Trims beautifully

Bought a new house with two large hedges. I got this hedge trimmer at the same time as a mower combo using the same batteries. This thing is great, I can walk along the hedge and get a really nice even cut at the top and shapes and trims the face beautifully.

Great Trimmer

Should have bought one years ago! No more climbing ladders!!

Rob Waikato
Good machine

Very efficient trimmer. Can be used at different angles to get good access to the hedge. The battery lasts well. The only problem I have is the weight of the appliance. The head is heavier that I thought and is difficult to balance. I suppose I’ll just have to exercise more for upper body strength.

Hedge trimmer is a Good tool but could come with an extra extension like the Pole saw

Pole saw is an excellent all round tool

Greenworks long reach hedge trimmer

Well packaged, easy to assemble. I thought a little heavy at first, but purchased balance clip on strap, much easier. Very sharp trimmer. Highly recommended. Another Greenworks to my collection
