Using the machine is very easy and allows for a much better reach. The battery lasted about 20-minutes which probably isn't long enough but recharging was very quick. A second battery would be a good option.

Got but has shortcomings

20 days ago


I bought the hedge trimmer in addition to the pole saw I already have, so I know the brand. It is light and works pretty well, but it is a bit too short and the brackets the work the extension part are a bit iffy and can slip. Overall, not bad but could be better.

I researched several long reach hedge trimmers. The Greenworks was very competitive price wise. I have used it to trim my hedges & was impressed with the battery life. I have only used twice & am hoping for years of reliable use.

This worked well. Cut nicely and I was able to cut top of high hedge without a ladder. The cutting blade connection to handle was I thought the most fragile part but so far has caused no problems. Getting over my veggy garden to cut sides was easy with the extension. Neighbour wants to borrow and I need a beer so no worries there.

The hedge trimmer works really well. Plenty of reach and power. The battery time is excellent.

Makes ladder work easier

Easy to use and good battery life. Much better balanced than other makes I have tried. Would be a little better with more extension but this would probably be to the detriment of balance and therefore more awkward to manoeuvre.

Certainly value for money. Light with good battery life. Head is easily adjustable as is pole length.

Hedges Beware!

This is a good gardening tool. It’s important to remember that it’s not a chainsaw, and that it will only give you a certain reach – so DO NOT over-extend yourself! I have found it more than adequate for doing the job for which it is designed. The 40V battery life is excellent – and as others has mentioned, it tends to outlast the user for most jobs. And I also agree that the weight of the battery provides a good counter-balance to the blade end, which makes for easier handling and use.

Had great reach, but seemed a little flimsy. Possibly the plastic makeup needs to be more robust. A lot of twist when it is fully extended. It is also very heavy with the motor being at the end. Fatigue is an issue after 20 odd minutes of holding this puppy up.

Peter Bay of Plenty

My only comment that is not positive, is that it needs a more grunty battery and a longer reach by about 30cm.

Great product, works really well but seems a bit flimsy. Light, good power, not a bad reach. Quiet with no mess. Will see how it holds up over time.

Great trimmer for the price, the head moves around abit when the shaft is fully extended, but not a huge issue. Trimmer works okay, battery has good life. Good value for money.

Happy Customer

We were looking around for a hedge trimmer that 1. would reach to the top of our trees. 2. angled so we could square the top off. 3. be cost affected. 4. environmentally friendly. we went to a few well known branded companies but the range was either very small, highly priced or too heavy. We had recently bought the Atom Ladder from Trade Tested and therefore looked online to see what was on offer. As we were picking up the ladder we had the chance to see the Long Reach Hedge Trimmer at the showrooms and bought it. Well, it was out of stock so this told us that this was a pretty popular machine. The great thing was that this was battery powered and could be used on any further Greenworks products we might buy in the future. the cost was well within our budget. On the day we picked it up two other happy clients were picking up the same product and we had stories to tell of how we use to trim our hedges and trees. The job is done in a 10th of the time as coupled with the Atom Ladder it is certainly a win win situation for us. Oh and did I say that the staff at Trade Tested are amazing?

Works well & not too heavy. I am pleased although I am not able to reach the middle of the top of my camellia hedge from the ground which is the reason I purchased this model. A miscalculation on my part because of the depth of the hedge. I will need to reduce the hedge height.

Easy to use good sharp wide cut blade, and if you get the 4 Ah battery lasts ages and its a good balanced tool.

Have only used once since purchase.Easy to operate,safe as not necessary to climb ladders & no electric cords to cut.Machine went well & was easily assembled for 1st time operation.Impressed.

Jim Manawatu

Excellent Hedge Trimmer

Cuts well & blades look well constructed. Note that the blade end is bit heavier than petrol models because the motor is at that end. I find that the 4Ah battery makes the balance a bit better because of the extra weight at the rear.

I needed an extended hedge trimmer to top light branches in a neighbouring tree. This tool is light and efficient. Does exactly what we needed at a reasonable price.

A great product which is a great deal lighter than the Husqvarna I was using and it has yet to run out of energy and a lot cheaper than other battery models
