Describe Yourself:
Beginner- Casual Do-it-Yourselfer
It’s SO great!
I bought the DeWalt 20V 2x max 3 in 1 cordless mower for my “medium sized” yard. It uses the same batteries as the string trimmer, leaf blower and hedge trimmer (all great also!)
After reading the other reviews, but before getting the mower, I bought 2 more batteries (for a total of 5). NOT necessary for my yard! I mow the 100 or so square feet and the 2 20v 5ah batteries are totally enough. It takes me about 30 minutes with stopping to dump the grass 3 or so times. If you have a huge back yard with three foot high grass, get a gas mower. If not, get one of these! I love the fact that it stands up on end when not in use. Very compact. I do recommend this and the other yard tools. They are very convenient!

Dewalt 20v mower
I purchased the mower to mow a bank that is too steep for my riding mower. It will be two months before I have any grass to mow so I can't comment on how it works. It looks like typical Dewalt quality. It looks good and feels solid. I have many 20v Dewalt tools.

Power without cords or gas
I love this tool, the lawn mower is excellent for small areas. If you expect to mow your pasture, this is not for you, but for regular size backyard this is a life saver. It has plenty of power on the 2 20V batteries, it is light weight and easy to maneuver. I really like to fold and stand feature for storing.

I would highly recommend this lawn mower, especially to people with smaller yards. It is worth the investment. And if you need longer run time, you can get a bigger battery.

I do agree that dual charger would be a great addition to the tool, since it runs on 2 batteries. But if you have more than 1 tool, you usually have more than one charger.

Works great, but you need extra batteries.
This mower works as well as my gas powered mower. I can mow 3/4 of my lawn with the 5ah batteries provided. With one charger provided it can take some time to recharge and finish the lawn. I own DeWalt power tools so I switch to my 3ah batteries to finish. The light weight of the unit is a plus for an older person such as myself.

Quiet and Easy to Use
I use the mower along with the 60V blower and trimmer. I can use two 9ah batteries for a completed job on my urban property. It is quieter than any other system I have used.

Perfect for small areas, mulches well too!
I'm all in with 20V Max tools so I have plenty of batteries and chargers. I can mow my long curbside grass strips and grass area in front of the house as well as my moss carpet in my large front yard (about half of it is in mulched beds with four of my 5V batteries. With two chargers, I could mow all day if I wanted as they charge quickly!

A Great Mower with Totally Deficient Batteries
Dewalt sabotaged this product by shipping it with totally anemic 20 volt 5 AH batteries. The batteries that shipped with it are fine for blowers, drills, impact drivers etc. But they are totally inadequate for the mower and result in poor ratings. Whoever at Dewalt decided to ship this with the 20 volt 5 amp batteries should be fired. Luckily before I ordered it, I read the comments of people who used Flexvolt batteries and they were fine.

I am a Dewalt user who owns 5 Flexvolt batteries (3-6AH and 2-9AH. With these batteries, the mower is awesome.

Pros (using Flexvolt batteries)
1) I was able to cut long grass on a ¼ acre lot using the 9AH Flexvolt batteries with power to spare. We repeated the performance on my son's ¼ acre lot. Run time was over 45 minutes.
2) I purposefully cut wet, long grass with the mulching attachment and the mower had plenty of power even in tall grass.
3) The mower did not bog down in sedge grass that would stall my Toro mower
4) The mower is easier to push than my Toro Personal Pace mower because it is light and has larger wheels on the back. I have a 10 foot hill in my back yard and even that was a breeze.
5) The mower is quiet. I'm not sure how many decibels but you don't need to wear hearing protection like a regular mower.
6) The mower cut every kind of grass and weeds we threw at it without slowing down. I have St Augustine (coarse grass) and Zoysia fine grass in my yard. My son used it to mow his weed patch and he commented how it just breezed through everything.
7) It cut much faster than my Toro Personal Pace mower. My son commented the same thing that it cut really fast because your didn't have to slow down and it's light.
8) Storage is is simple and easy and there is no gas so you can store it vertically in the garage. This also lets it dry if you hose it off after doing the lawn.
9) Adjusting the cut height is super easy
10) I gave the mower the acid test to make sure I was ready to go electric before getting rid of my gas mower. The mower exceeded my expectations.
11) I will never need to fool with gas, oil, starting issues, cleaning air filters, changing oil, changing plug, smelly gas in the car and excess noise again. Priceless.

1) if you use the 5AH batteries provided they will get HOT and give out very quickly. Flexvolts only get a bit warm and work great.
2) Even without the mulcher insert, the grass quickly jams the discharge chute and it becomes a muncher. The grass catcher is not very big.
3) It is slightly narrower (20 inch) than my prior mower. Requires and extra strip or two in the front lawn.
