Dewalt 40V Blower
The blower is up to Dewalt's high quality standard. It has a solid feel, but is not as heavy as a traditional gas blower. The brushless motor provides an air volume and air velocity similar to a gas-powered unit. Overall, it is somewhat quieter than a gas-fired unit. Battery life is acceptable, but not great. An extra battery would be helpful; unfortunately, the cost of an extra 40V battery exceeds the cost of the complete refurbished blower unit complete with blower, battery, and battery charger.

Convenience + Performance
I recently got my hands on one of these and it's now in daily use. It offers comparable performance to gas blowers with a ton more convenience.

Powerful enough to clear debris from smooth surfaces as well as grass.

Quieter than most of the gas models. Also, it doesn't need to idle like gas models so it is silent when not in use.

Great trigger feel and responsiveness with a nice lock that can maintain any throttle setting

No emission – no need to close all the windows when you fire this up

It runs cooler than gas models

Low vibration – no internal combustion engine = less vibration

More to come – The 40V DeWalt line will surely expand offering a ton of great tools and equipment

No need for gas

Good run time. I cleaned up my entire yard (about 30 minute of use) on one charge. I haven't checked to see how long it can run continuously but it was more than enough for my 1/2 acre lot.

It's not as powerful as the mid 20 cc gas models. This delivers about 10% less CFM at 400 vs. 440 from most gas models. It's still quite powerful, but you'll be taking a hit during max output.

This leaf blower changed my life
After fighting with a two cycle blower one too many times, I bought this and it is the best investment I have made for my house. Quiet, charge lasts for around 35 minutes. I live in a forest and this thing is worth its weight in gold. I wish you made other chargeable items like a chainsaw, snowblower

Cannot imagine a better blower.
This blower is the bomb! Of all the lawn equipment products I have purchased of late, this is hands down my favorite. I do my own yard work which includes mowing and edging the grass, trimming hedges and blowing loads and loads of ficus leaves from under a monster size ficus tree. This blower has the power to do it all with ease and the charge time to finish both the front and backyard in one charge. Love the variable speed, the ability to set a level of power and yet still increase on demand, the charge time left display and the quick re-charge time. I cannot think of one negative. The only thing to be aware of is if you switch to your left hand, you need to keep the blower away from your leg as the fan that sucks in the air is on the right side of the blower. A great, great product!

Very powerful
Very powerful and easier to use than my gas powered unit
Just snap in the battery and your are ready to go
After 1 1/2 hours of running The battery still had 1/3 of the power remaining.
Easily handles leaves and grass clippings and is great for blowing out the gutters

Dewalt Blower 40V
I was a little concerned the power would not be enough to blow with leaves but it has definitely lived up to my expectations. It's nice to have a cordless option that instantly works. Not to mention it is fun to chase my 2 year old around the yard.

Does this blower have a thermal overload shut off on it?
I just got this blower and after about 5 mins of use it shuts off.
Bob on Apr 14, 2016
BEST ANSWER: Don't know about the thermal cutoff. Mine has never shut off on me. Make sure your battery or charger aren't bad--batteries especially I've heard can be duds.

Can i use 2 20 volt batteries in this?
A shopper on Nov 12, 2016
BEST ANSWER: No you can not use 20v batteries on this unit . It has a much larger 40 volt battery.
Any belt problems?
Douglas V on May 6, 2017
BEST ANSWER: Nope. The new models have a different design on the belt pulley. Love this blower.
how does this unit compare in blowing power to the gas powered units? how long - number of minutes, will the blower battery last?
No nickname. Name is Ted on Sep 25, 2015
BEST ANSWER: I sold my Echo backpack blower because this cordless has almost the same CFM. Now I use it 10 times more than the gas ones because I don't have to check the fuel, (mix gas and oil if low), prime it, choke it, start it, let it warm up then use it. With the cordless DeWalt you just pull the trigger! So it gets used way more, great for cleaning off sawdust in the shop because your not running a gas engine inside. I mainly use it for leaves and blowing grass off the driveway after mowing. Also clean off the 4 wheeler, lawnmower, pollen off of vehicles etc. Im very happy with the unit, the other thing is I had a hand held gas blower but my hand would go numb because of the vibration of the gas engine and it could also burn your leg if you weren't careful. My wife and kids use this to and don't have to worry about them using the wrong gas or not getting it started!
Will the flex volt battery work with this blower?
A shopper on Oct 16, 2016
BEST ANSWER: The flex volt system is only compatible with the 20 volt series.
Does this model (40V Cordless Blower) come with other attachments - i.e. hedge clippers?
If not does Dewalt have dual purpose - battery powered - lawn tools?
None on Aug 2, 2015
BEST ANSWER: No, the blower does not come with any attachments. However, Dewalt DCHT860M1 is the model number for a hedge trimmer that operates on the same 40V system.

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.
