Sharp, well balanced trimmer
We purchased this this summer and are very pleased with it. I have the 40 volt pole chainsaw and saw this. Both are great. Nice to be without cord when trimming and electric pole saw is much lighter than gas one.

I highly recommend both.

20” cordless pole hedge trimmer rocks!
I’ve had this trimmer for a few years. I have healthy 12’ tall redtip hedges forming a border around my yard. Before I got my Greenworks trimmer, I hauled a ladder and a very long extension cord around the property. It was hard work and not particularly safe. My Greenworks hedge trimmer rins on a 40v battery. I am not a big person but I can handle it easily. To reach the tops I use a stepstool, much lighter than the ladder I used to haul. For safety, light weight snd a very efficient blade, I give this tool 5 stars!

Battery won't last after 1 year of light use
Bought this because of the extension. It works fine, the extender is a bit flimsy and when placed at the 45 degree angle thats kinda worthless. Wont cut very well when you do that. BUT my biggest complaint is the battery stopped holding a charge after one year of light use. It charges but runs out within 10 min of use now. Worthless.

A portable trimmer is very handy for quick trims or heavy home landscaping away from an a/c outlet. I gave it 4 stars because the battery and lower handle are very heavy which limits the time that I can use it.

Like this tool very much. I have the 24 inch hedge trimmer which is powered by the 40 v battery, so now I can power both using the same battery. Trimmed over 10 huge shrubs going back and forth between trimmers and still had 2 of 4 lights on the battery.

Very satisfied
Just what I was looking for to trim hedges and small limbs from trees without having to get a ladder. The weight is not an issue, because it keeps the wife from using it, which is a good thing!

Works as advertized
It has all of the "juice" that I need for my purposes. I trimmed a fairly tall bush, which grows several feet in a year. It didn't have any problems cutting it back, however it doesn't "pickup" after itself! I've got about a pickup truck load of branches to pickup. After the purchase of the cordless tree trimmer and the hedge clipper, I've become partial toward them, over gas powered tools, for the same purpose.

I have the Greeenworks pole saw, will this hedge trimmer fit on that power head. Can I just remove the saw and install the hedge trimmer???? If so I do not need to buy the battery holder.
A shopper on Feb 5, 2017
BEST ANSWER: The heads are not interchangeable. With Greenworks, you just need to make sure the Battery voltage and series are the same (40V Gmax, 40V, 24V enhanced, 24V). As long as this tool matches the same voltage and series of the tool that you already own. Then you can just switch the battery out between the two tools.
