Great - not so Great
I bought this mower a few months ago and have had a chance to use it on grass and in leaves (mostly maple. I so wanted to give this a 5 star review for the great things I like about it. But, before buying this, I did read all of the reviews and, unfortunately, I am finding the same limitations others found (poor run time, an unacceptable charger). I have a small city lot and a pretty sizable collection of other Dewalt 20v tools/batteries and chargers to supplement that which was provided with the mower. So, for me, this means these limitation are of a marginal concern. Overall, I am pleased with the mower and the run time on the 2 - 5 amp-hr batteries is sufficient to mow my lawn on a single charge (about a half hour), but is insufficient if I am dealing with fall leaves. And, I find that packaging this mower with only the single slot slow charger to be unacceptable, especially considering that Dewalt has a 2 fast chargers that could have been packaged with it. Hence, a large part of my 3 star rating.
Here’s what I have found to date:
Pros: The mower, other than the noted limitations, is basically well thought out, well designed, and built to the high end level I expect from Dewalt. It has nice features such as an easy to fold handle that doubles as part of the support for storing it on-end and the single lever height adjustment, which I use multiple times while mowing. The housing and handle are metal and quite substantial. Use of plastic seems to be appropriately done. I have not found places where I would wish they hadn’t used plastic. The section of the height adjustment mechanism for the front wheels includes a spring that allows for front wheel movement which absorb some of the shock of pushing the mower over my rough lawn. The housing and blade design does well at mulching and, with the bag attached, does well at picking up leaves, cutting them up and stuffing them in the bag. It does well at fully filling the bag, which is good as the bag is a bit on the small size. The mower weight is reasonable given its quite substantial metal housing. Its wheels are sufficiently large to all it to easily roll over my lawn (they are larger than those on my gas mower). The motor power, when fully up to speed, is good and sufficient enough to handle cutting up and bagging the maple leaves covering my back lawn. However, note that the mower has very little starting torque and it struggles to get going if there is cut grass and/or leaves in the housing and around the blade. The 20” cut path is nice and better than some other brands. No gas, oil or cords to deal with and, of course, the batteries are usable in other Dewalt cordless tools, if you have them.
Cons: The charger. Dewalt included their 2 amp slow charger (DCB112) for charging 2 - 5 amp-hr batteries. That is 5 hrs of charging, or more if you can’t catch the first battery right at the end of its charge cycle. With 2 batteries it is not even possible to charge these overnight and have them ready to go the next day. I find this to be unacceptable, especially considering that Dewalt has 2 other fast chargers that could have been included (DCB115, single slot [not really desirable either], or DCB102, 2 slot). Even on my small lawn the run time with the 2 - 5 amp-hr batteries is marginal. The location of the cord from the end of the handle to the motor is such that it gets pinched in lower hinge of the handle. That pinch point is scissor-like and, eventually, is going to cut the cord. The rear discharge option is useless in all but dry grass as it easily clogs.
Observations: While I really like the single handle height adjustment, the lever for this can easily get caught on bushes or the like, and change settings. Sharpen the blade, which is not very sharp out of the box, and keep it sharp. This will improve run time a bit, along with mulching and cutting up leaves. The safety handle is very sensitive to how it is held. I have had the motor trip off at times when I thought I had a good grip on it. 2 hands work the best.
Conclusion: This mower suits my needs; my “Pros” are what I like about it and there is not much for me not to like. I would recommend it, but with the reservation that the person be someone with other Dewalt cordless tools, and has only a small lawn.
For Dewalt: This could easily be a 4 or 5 star mower but for the charger and run time. This mower commands a premium price against other brands. For that premium price, you have the charger on the shelf that should be included; that is the 2 slot DCB102 high speed charger. As for run time, that could be addressed by offering a trade-in option of the 2 - 5 amp-hr batteries for a heavily discounted priced pair of 9 amp-hr or larger batteries or package the mower with different battery options. Finally, the cord needs to be re-routed so it is not pinched by the handle.

Very well though!
I bought this last week. Used it for the first time with my dewalt flexvolt 9.0ah batteries and it worked great! I read many reviews saying stock battery last very short time but having the multi battery charger and owning many batteries already it wasn’t bad. I did all my front and back yard in one charge no problem. It’s very smooth, it’s not as loud as gas lawn mower and very light and easy to store away! I’m very OCD and I love how I can fold it and put it against my wall to take less space. It was great that my flexvolt battery’s were compatible with this machine! Looking forward to purchasing more of dewalts innovative tech!

Good mower but needs to come with 2x9 Ah batteries
Overall I like the mower but the 2 x 5 Ah batteries it comes with is not enough capacity to cover even 1/4 acre (with a house on it). Having said that, I still prefer it strongly to gas mowers.

Disappointed in battery
I've used a battery operated mower for years with no issues. This mower is easy to use and great in every way except for the battery. Lasts 20 minutes tops, when you add in charging time it usually takes me 2 days to mow, when I could previously mow my lawn in 30 minutes. Very disappointed.

On my second mower and it is broken
I have just gotten my second mower and each time I am able to mow my tiny lawn until the end and then the blades just stop turning. I have no idea why. I dont have anything hard in my lawn. It is just grass. I used the first mower one time, took it back got a new one and the exact same thing happened. WHAT IS GOING ON?????

Great power, easy mower height adjustment. Easy out of the box set up with minimal effort. Battery life seems to be okay. Perfect for my smaller yard. Love that it matches my stable of DeWalt power tools!

Disappointed Purchase
I was disappointed about the lawn mower. I waited for about 4 months for the lawn mower to be released and I even paid in advance for the lawn mower hoping that the satisfaction will worth the wait.

1. For the 2x 20 lawn mower - The lawn mower is expected to use two batteries at thesame time. Although it came with two batteries, they only included one charger.
This is what it means - if you are cutting and ran out of battery power, you have to wait and charge the battery one after the other before you can continue using the lawn mower. I expected the company to put two chargers.
2. The fully charged batteries do not last long enough to cut the front and the backyard which is less than 1/4 of an acre. In most cases, I have to cut the front and wait to charge the batteries and cut the backyard the next day.
3. I gave the lawn mover 2 starts because of the quality.
4. Think twice before you investing your money on this product.

So little lawn so many batteries.
I have a half acre of lawn. Initially purchased 2 extra flex volts just to have around. Found out that I need two more to just cut my fourth acre in the front of my house. 6 batteries for 1/4 acre does not make sense when it says the 2 it came with should be sufficient.

Needs at Least 12Ah to be useful
I love this mower. The height adjustment is excellent. The mulching is perfect but the batteries simply do not give enough runtime.
My yard is 5000 sq ft and I'll get through just over half before I'll have to recharge.
Wait until DeWalt does the right thing and gives the 12Ah batteries in this mower for this price. As it is it's too much money for not enough mower.

  • 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.
