Great tool.
Great tool. Light, powerful and good battery life. 2 batteries should keep this going if you charge one while you're working.

Having the Dewalt 20v system is very handy. Save money by buying bare tools.

Terrific Hedge Trimmer
I was specifically looking for a cordless hedge trimmer that would utilize my existing power packs from my tools. This tool accomplished that. It is light weight but strong.
It hits all the markers, quality, performance , and value.

Great Trimmer
I already had a 20V cordless drill driver set, was considering buying a trimmer attachment for my Shindawa head, but st $300 was hesitant. Noticed the bare tool and the price, bought it and I am very pleased! Very ergonomic, light & I used a fully charged 5.0 amp battery with a boxwood hedge I could’ve done 3 times the work before the batt needed charged. Love it!

Will battery from screwdriver fit?
Samdam on Jul 1, 2018
BEST ANSWER: Battery? What exactly do you have? The 20volt lithium fit. I use 2 to 5ah batteries.
Does it use the same battery as blower and trimmer?
A shopper on Apr 28, 2018
BEST ANSWER: Yes. And it is a great trimmer. I have not used for extended periods but works very well.
Can I use 40v battery for this hedge trimmer ?
TN on Sep 4, 2017
BEST ANSWER: No, the 40v battery is too large and the connection is different.
The manual says to use a "resin solvent" to clean after every use. What is a "resin solvent"?

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
