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.

Note: This tool does not include a battery or charger, these must be purchased separately.

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 (battery and charger sold separately).

The 51cm laser-cut dual-sided steel blade gives super smooth cuts and can deal with the gnarliest privet up to 18mm in diameter. The head can pivot through 125° into 7 different positions for total flexibility, letting you can cover all the angles including the underside of your hedge.

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.

This lightweight design includes safety features like dual switches to prevent accidental usage and a safety brake.

Level up your power garden tool arsenal with the amazing G-MAX Long Reach Hedge Trimmer and 40V battery system today.

Is the shaft of fixed length, or can it extend/retract ?
The shaft is a fixed length.

How heavy duty is this in terms of thickness of hedge trunks and branches. Thanks
Greenworks quote an 18mm max cutting capacity, so if you're tackling something really gnarly the Greenworks Pole Saw might be a better bet?

I have one of your blower vacs with a 40V 4AH battery rather than the 5AH mentioned. Space in my garage is limited for chargers so will this battery work with this tool
Yes it will, all the Greenworks 40V batteries will work in any Greenworks 40V tool.

Does it include a harness or strap to go over your shoulders?
No it doesn't, although it would be easy enough to add your own.

Solid garden tools

I have both the pole saw and the pole hedge trimmer, so I can interchange the battery. 40V batteries have enough power to get most of the major garden jobs done and no need to balance on ladders. I rate these tools.

Wish I had this a long time ago. Does an excellent job with plenty of cutting power. Much safer than climbing up a ladder

Debbie Wairarapa
Great tool

So much better than petrol as starts straightaway every time. Performance was equal to my last petrol model but without the noise and fumes

very good cut but needs a harness

Long reach

Trimmer seems quite powerful and cuts well. Due to length there is quite a lot weight to hold if extending out. This would benefit by having an adjustable grab handle to hold and help control the unit. There is a foam band which is not really useful in taking the weight.

Extension trimmer.

This is my second Greenworks extension trimmer. The new one has a metal shaft which is much stronger and the unit is quieter as well. Great piece of equipment, also the batteries from previous unit fit. Great.

So far so good, good battery life and excellent cut.

This is a good machine, however it is a little top heavy, and the cutter head could be more adjustable, to make trimming more accurate.

Ev Auckland
Greenworks Long Reach Hedgetrimmer

A good product. Does what it does very well. Because it is a long reach unit, it can be a bit heavy when reaching out. Consider using a 2 amp hour battery to keep the weight down.
