Don’t take low reviews to judge
I almost passed on this due to reviews even though I’m a Dewalt person. Out of box-ready to go. Charged batteries only 1/2 charge to see if I liked. I’m over 55 &in Florida heat hitting 96 today. 1 pinky driving in self P mode.. no energy exerted but basic walking. I mowed .40 acres at 3pm sun 96.. just a test was whole yard lol. Well worth the $. Charge held up fine. Cut high thick grass w ease on low level 1 (Side note; batteries Hot after& cooling before able to charge: not sure if normal)

    Dewalt mower
    I don’t have a huge yard to mow. A little less than a 1/4 acre of grass. I was blown away by this mower. I’ve only bagged the clippings. Haven’t used the mulch function. Was able to cut my whole yard and the supplied 10 amp hour batteries still showed full charge. So battery life thus far has been a non issue. It cuts well and works great. No more gas cans and fumes. I have the trimmer and blower as well. I’m very happy with the ease of use and performance.

      Better than what I was expecting
      Great performance, use less than 1/3 of the battery charge to cut all my back yard. Definitely much better than my old gasoline lawnmower.

        Disappointed and Dissatisfied
        Purchased this unit a year ago and it has never worked . The torque and suction power of the blade is poor. The battery life will not last 30 min on a full charge and I am forced to cut my small lot in 2 days. I am looking to get a gas mower and scrap this unit.
          Dead in 13 minutes
          I should have believed the reviews. I’m going to spend more for a Milwaukee, hope that works. My DeWalt days are over. Their circular saw is ok, not great, but after my experience w their blower and this mower, I’m walking away and may never go back to yellow.

            I bought the DCMWSP244 lawn mower and have used it once for 15 mins on short grass in front yard. When I went to the backyard to mow, the mower kept quitting when I engaged the self-propel. The indicator on the battery case was flashing red [FYI - this isn't even mentioned in the manual what that means or what to do - SEE PIC]. I let the mower sit for 30 mins and tried again. Same thing happened. Thought it might be the actual batteries, so I charged them overnight. This morning, same thing happened. Mower started, engaged self-propel, mower died. So frustrating and upsetting!
              Miles Better Than I Expected
              This mower is easily the best lawn mower I ever used, this is also my first battery powered mower as well. I was a little apprehensive buying it kinda doubting it would be as good as gas but man was I wrong. I fired it up after charging the batteries the next morning and I was surprised how quiet it was. I thought for sure it was going to be extremely weak. Nope it handled a very damp and 3 week non mowed lawn like it was nothing. Areas where I know a gas mower would get bogged down or stop this thing cruised through them like a Sunday drive down the boulevard. Minimal vibration and gets the job done easily. Not to mention I STILL had enough power in the 10ah batteries to pop them out, put it in my weed trimmer, knock that out AND stuck the same battery on my blower and was able to finish that with zero problems. Dewalt makes a chore an absolute pleasure

                Poor Engineering
                This lawnmower pull handle hits the handle creating pressure on the brittle yellow plastic. Putting pressure and breaking the plastic. I bought 5 of these units and everyone of them is broke in the same place with 5 different people using the machine. I looked to get parts to fix them and it’s out of stock. That’s telling me it’s a known problem that should be recalled. Both side are lifting. Notice the pull hand it’s the bar and does not rest flat to the handle. The nine self propelled is a lot better than the self propelled
                  Gool Alternative to Gas Mowers
                  I bought this just a week ago. Some assembly, but took very little time & not complicated at all. Great little workhorse. Easy start, mowed my very thick, rolling hills lawn for over 1/2 hour and the batteries were still charged. The self propel is a little weak, mostly intended for flat areas, but still worked & not bad to handle due to its relatively light weight. Word of caution; make sure the batteries are fully charged. I read some of the reviews with people claiming they cut their lawn with the charge that was provided right out of the box, and I would say that is a recipe for frustration. I tried that and it was aggravating, because it ran for about 5 mins. Also, be sure that the receptacle you are using grabs onto the charger plug prongs nice and snug or you will get a false full charge reading. Long story short, I do like this as an alternative to gas powered mowers. It has plenty of gusto, you don't need gas, spark plugs, and NO STINK! My only complaint is the condition of the box when it arrived.
