Lots of factors should be considered before you purchase a hedge trimmer. You need to think about your budget, the power requirement, blade length, comfort, and other features. Greenworks 40v cordless Li-ion hedge trimmer meets all the conditions you have set. This hedge trimmer is not only efficient but also incredibly powerful with 3000 CPM.
Greenworks hedge trimmers are built around the notion that lawncare does not have to be stressful. If you have been putting off trimming the hedges because you do not want to use your trimmer, it's time to replace it. This hedge trimmer comes with many features, including less vibration compared to other brands. Its brushed motor allows for easy control, and the blade opening is just right at 27mm. It is also long enough at 61cm, so you do not need to get too close as you trim.
Please note that this item is only the hedge trimmer itself. The battery is sold separately or in a kit. You can find the complete package here.
