DCWMP600X2
Initial Introduction
From various Reddit threads, to two separate Equip Expo visits along with a handful of recall notices it seems like I’d been eyeing this specific mower for the better part of two and a half years. My initial interaction with this mower was at Equip Expo 2023 in my hometown, Louisville, Kentucky. Being that it was my first time ever attending Equip Expo I made it a point to head straight to the DeWalt booth to see what they had to show off. Needless to say, I was pleasantly surprised at the sight of a Flexvolt lawn mower option.
Over the past few years I’ve invested in a handful of DeWalt outdoor power equipment products and I have to say that I only really have a desire for Flexvolt powered tools. At least as it pertains to outdoor power equipment from DeWalt. Upon moving into my first home three years ago one of my two initial purchases was a Flexvolt string trimmer. Followed swiftly by a Flexvolt 20 inch chainsaw.
Once I got a little closer to the fall months that same year I ended up purchasing a Flexvolt handheld leaf blower. I sat on the fence about purchasing a DeWalt lawnmower as I assumed that at some point they would have to release a Flexvolt version. Fast forward one year later and that was seemingly the case, well that was until it wasn’t. That is until it wasn’t. The first delay came in early 2024 when I got news of a massive recall notice on the few models of the mower that I was looking for before they really hit mass market status. This put a significant damper on my ambitions to have a Flexvolt mower and ultimately I made the choice to sit it out another year.
Upon my returning to Equip Expo in October of 2024 I noticed that all DeWalt branded mowers were missing in action. Absolutely not a single mowing application from DeWalt could be found in, at or around the Kentucky Exposition Center. For the nearly six months following Equip Expo I noticed a series of almost release dates along with an equal number of restarts. I believe it was around May 2025 before one of these units were made available for shipment. I gave it another three or four weeks to make sure that it was for real this time, then I finally pulled the trigger right around Father’s Day.
Battery Capacity Trials
My initial intention was to run a documented series of battery capacity trials. Being that I’m new to this influencer shit, sometimes I ran documented trials while other times I just cut my grass and wrote about it.
First Time First Impression
I have a mixture of Rye, Bluegrass and Tall Fescue. To give you additional context, my yard is about a half an acre. Lately I’ve been allowing the grass to grow a little higher than I like. The purpose for this is to self seed some of the areas that were left a little patchy from my decision to dethatch the yard in the middle of the Spring.I started mowing right at 7:30 pm on an early Summer evening. I wrapped up right at 9 pm, saving just enough time with adequate light to see the job finished. I loaded the mower up with a 6Ah battery pack and I honestly expected it to run just a little while longer than it did. In fact, I had to supplement another battery pack after my second 6Ah pack ran out in the front yard. All in all, I have to say the runtime is still very impressive. On the box it says that it’ll run for about 80 minutes but that is with the two 9 Ah batteries running concurrently. With that noted you can see just how much this unit exceeded those claims.
Second Impression
For my second time using the mower I loaded it up with a 9Ah battery and I was able to cut through roughly 60 – 70 percent of my yard before the initial battery pack lost its charge. My original plan was to load it with a second 9Ah battery but I knew that I didn’t have enough yard left to warrant partially draining a fully charged pack. I instead went for a 6Ah and proceeded to use up just over half of its capacity on the remainder of the yard. I cut the grass in a different orientation for my second time using the mower and it seemed like I spent a considerable amount of time in the red zone on the blade throttle indicator. One of the things that quickly came into question was the long term viability of the mower. Mind you, I have an area of grass that grows three or four inches above the height of my ankle. It’s not super thick grass and it’s not a very large area of grass either.
The overload detection and mitigation technology is certainly one of a kind. I was very impressed by how quickly the machine can detect an overload scenario and subsequently adjust itself to move over it as if it’s just any other part of the yard. I’ve seen where some folks have bashed the cut quality that you get in these scenarios but I have to say that it really only does it when it has to.
Third Impression
Prior to my third time mowing we’d received an unusual amount of rain for mid July for the past several days which led to the grass growing taller, thicker and faster than normal. I was pretty much left with a window of time to cut the grass, which meant it would still be a little wet from the previous night’s rain. I otherwise only had a handful of hours to get it done before the next pop up storm rolled into the area. I started cutting the grass around 11AM and by 3PM I was under a moderate thunderstorm. I had just enough time to get both the front and the back cut as well as string trimmed and blown off.
From the previous cut I still had the mower deck set on 3 which was fine for most of the front yard but I quickly realized that that wouldn’t work in the back. I was able to cut about ten strips in the thinner area of the yard before I opted to raise the deck to a 4. From there I started off bagging but the longer I went the more and more I realized that this mower does not discharge wet grass very well whatsoever. I eventually switched from bagging to trying out the side discharge for the first time. This is where and when I realized the issue that I was running into. Nothing was discharging. Therefore I put the mulch plug back in after I removed the side discharge chute. From there it seemed like things went much smoother to round out the cut. I don’t think that this is necessarily a knock on the DeWalt mower but it is a factor worth considering. Clearly this mower was not designed to tackle less than ideal operating conditions. I could see this being of particular concern for anyone with fairly large lawns, especially in areas that see heavy seasonal rainfall.
As for the battery test. I went through what had to have been about five batteries. I started out testing the 12Ah battery. It didn’t make it through the whole front yard before I had to change it out. Once I knew what I was in for I scrapped the battery test and went ahead and loaded up a 15Ah battery. I’m noticing that the performance degrades sharply towards the end of the battery charge, regardless of the pack size. Therefore I find it very advantageous to just swap it out before it gets to that point. Clearly when the mower has to perform at a ramped up RPM the battery won’t last nearly as long. On this day I will say that a majority of the workload placed on this mower was well into the RedZone.
Fourth Impression
It wasn’t until my fourth time using the mower that I realized that in order to achieve the cleanest, most even and prettiest cut you may need to run the mower twice and empty the bag roughly 27 times. I wanted to get an extra cut midway through the week so that I didn’t encounter the same things that I ran into the last time when I had to cut through the thickest and wettest grass I’d ever seen. Although it had only been a matter of three days since I’d last mowed the grass I could see it thickening up in several areas. Therefore I made the decision to go ahead and get the yard cut while it was still somewhat manageable.
After cutting through about half of the yard I began to realize that things would look much better if I went back over things and picked up all of the leftover clumps of clippings. I ended up doing just that and the results were nothing short of mind blowing. However the end result made the extra time invested well worth it. It was super satisfying to see what this mower is truly capable of when the conditions are most ideal. Not to say that I wanted to commit to this methodology going forward but if it got the results then you might as well say that I was all in at that point.
Fifth And Final Impression
By the time I got around to my fifth time using the mower it was basically as if I’d grown accustomed to all of the nuances that it had to offer. I’d found that mowing over the grass twice in spots where it was a little too thick to pick up was the best overall solution for getting to the quality of cut that I’m looking for. I would say that by my fifth time using the mower I had begun to hit a stride as far as familiarity and expectations. By my fifth trial it became easy to determine which battery pack to use based on the ambient conditions. I’m fortunate enough to have a multitude of battery packs that offer me the variance needed for specific operating conditions. Ambient heat and moisture coupled with the length and thickness of the grass should be quickly considered prior to cutting. This will just allow you to select and ensure that the proper battery packs are charged and available for use. Trust me when I tell you how infuriating it is to have to swap out 6Ah batteries every ten minutes because your larger packs aren’t charged.
Closing Thoughts
My post season analysis would have to be about a 6/7 out of ten. There were certainly points where this mower shined as well as several instances where it flat out struggled. I think that in ideal conditions the DeWalt DCWMP600X2 is right up there with the best of them. It offers a clean and consistent cut, maintains power and is easy to use in an instant. When and where it struggles are the elements. Any distortion in normal conditions and mowing becomes a bit of a chore due to the additional power consumed, persistent stalling and additional bag unloading required. I’m eagerly interested to see how mowing throughout next summer will go. Between now and then I intend on stocking up on a few additional battery packs. Ultimately I think that your overall expectations of this mower have to be in line with the amount of battery power you have at your disposal.
