DEWALT Battery Lawn Mower - The DEWALT DCMW290H1 is the new 40-volt 20" lawnmower the can mulch, bag or discharge the clippings out of the rear of the mower. Currently, the 40-volt line is designed more for landscapers and contractors and the rear discharge would go along with that, allowing for easy use around seed beds and landscaping. The 40-volt battery line-up is currently available in 4.0Ah, 6.0Ah, and 7.5Ah battery packs. The battery pack included with this mower is a 6.0Ah pack. The DEWALT 40V MAX Lawn Mower is rated by Dewalt to cut up to 1/4 acre and from our testing, the runtime equates to about 12-14 minutes for an average height cut. There is a single lever that allows the user to adjust the height of the cut from 1.5" to almost 3.5". The wheels do have ball bearings in them and the build quality seems good. The metal deck is thin to be lightweight but also seems strong. The 40-volt battery used in this mower is comparable with the other DEWALT 40-volt outdoor power equipment.
Features
Brushless motor for high power output & runtime
3-in-1: mulching, bagging, and rear discharging
20 in. metal deck
Single lever height adjustment from 1.5 - 3.4 in
Folding handle and lift handles for easy transport and compact storage
40-Volt Performance
Since the DEWALT 40-volt battery is designated for commercial use in DEWALT's line-up of outdoor power equipment, we have some pretty high expectations for this mower. The large battery pack contains 3 sets of cells that each equal 40-volts. That is many more cells than the 20-volt line or even the FlexVolt line that is 60-volt. Even with the larger battery pack, the DEWALT 40-volt lawn mower is only able to run for about 12-14 minutes on one charge of a 6.0Ah battery pack. For most city lots, that would mean a homeowner would need to have at least 2 batteries. A landscaping contractor should easily be able to trim a yard and charge the battery again on their way to the next job. That would not be the case if it was a larger commercial job.
The lawn mower power is amazing and maybe what is killing some of the runtimes. We were able to cut 12-18" grass with very few stalls and no overheating of the 40-volt 6.0Ah battery. There is always a balance between power and runtime and this unit definitely has more power. That is a good thing if this lawn mower would be used as a trimmer. Ditch banks and taller grass is no challenge for this mower. We will go out on a limb and say that this is the most powerful battery operated mower we have ever used. The long grass we cut in the video shows the jaw-dropping performance this mower provides.
Build quality seems to be right up at the top of the pack with a nice metal deck that is both strong and lightweight. The deck is deep to allow the grass to mutch effectively and also bag well. There are two positions for the push handle that accommodate both shorter and taller users. Storage of this lawn mower is simple and effective as it can store standing up, therefore taking up a 1/4 of the ground space of a similarly sized gas mower.
Overall, this mower seems to have the power for normal mowing but lacks just a bit in the runtime category. It is priced right, so one could pick up another battery compared to the price of the closest competitor, the EGO 56-volt. DEWALT came out swinging with this mower and constructed it very well! - Навчання та стиль
This is one of the few cordless tools I still don't have ! Thanks for sharing !
Great review,informative....always quality videos,thanks.
***owner review***
This review is spot on. It is a quality build and it feels like a true Dewalt tool that you would come to expect. It cuts very well and I was impressed with the bagging feature. However, the run time is horrible. With the bag on I was only getting 12 minutes of run time. It takes up to 2 hours to recharge for just another 12 minutes of run time. That to me is unacceptable for a $400 mower.
I've cleaned it up and will be putting it back in a box to head back to the store here shortly. This is the first Dewalt tool I'll be returning to the store.
Dewalt, please improve the run time. This is a great idea and really good quality but not up to speed with the run time from your competitors.
great vid keep up the great content
Thank you!
EXCELLENT vid.
Picked up a 2x20v De WALT, (can use either the 20 or 40 volt batteries) Jun2 2021, which mowed through 1 meter high grass without bogging down in mulch mode. Started with 2 bars on both batteries and ran for 31 minutes in the high grass. Dropped back in to charger for another bar, to finish the area being done. Ran for another15 minutes, completed and battery done (good timing). Run life is a little short at the moment. New device to me, will likely pickup another set of batteries. Good too, can share batteries with other De WALT power tools.
I have the 40v chain saw and weed whacker. They both have amazing performance. Waiting for the dewalt 40v riding mower.
Dewalt quietly ditched the 40-volt line. No more new tools.
Of all technological advances made, breakthrough in better battery storage remains the holy grail.
i watched a video on that kind of stuff. there is a guy who has made a lithium battery that can be cut, stabbed, smashed ect and does not explode and at the same time has multiple times more capacity than we are use to. he is hoping in less than a year to have them on the shelves.
Ok then that explains what i saw in the store Thankyou I'm sure the nuts could have been loose in the store too ... Thanks again
much better unit than my 18v x 2 Flexvolt unit (DCMW564T2-TE) that I just returned for refund today, used once and very disappointed. Mine cut 225m2 only and stopped, with 2 bars on the batteries still showing. My grass was summer dry and way more sparse than your demo shots. I mulched and there was no zero grass left on the ground. My mower is rated 18v 6A or 54v 2A. My guess is that it runs at 54v 2A full time and then overheats. It ran for 25mins max. I used the 30day money back. I bought it bundled with the blower and loved the blower.
Positives:
Build quality is very good,
the handle does NOT rattle at the hinge like so many do
wheels have bearings so it rolls sweetly
Packs away and stands vertically for storage
Cuts very well and mulching is now a real thing for me
Blower is awesomely strong
Negatives:
Run time is a disaster. It should come with 54v 12A battery and it would then be a killer.
Background: I just retired my 30+yr old ROVER 2-stroke 18" mower and wanted to get into the 21st century. Dewalt has the brand image, but.......
I fully agree with all your positives and your Negative. Dewalt has one of the best-built mowers on the market but epically failed in providing runtime to the users.
The bag on the EGO 56V 21" self propelled works great. I have never had it clog.
What are you getting for run time? All I need a 21" walk behind for really is just trimming around trees, bushes, and yard perimeter since I have a lawn tractor. But really wouldn't mind the exercise just actually getting tired of the noise to the point I usually wear earbuds and bring my mp3 player along when I'm mowing to drown out the engine's drone.
I am able to mow 1/5 of an acre on a 7.5ah battery, though I also have a 5.0ah and 2.5 ah battery so I have always been able to complete mowing and weedeating.
Thanks for the information. It may work fine then for my trimming needs.
I don't bag or mulch with mine.
I prop the rear cover open with a bungee about 4~5 inches and take the plug out. It basically makes it a rear/left discharge.
I never try to mow in tall grass. I usually mow every 3 or 4 maybe 5 days during spring. Cutting very little and often and the battery lasts the whole yard.
Yard size is a regular size city lot, about 5000 sq ft. When the grass is in full-on grow mode I get about 90 to 95% of a mow done with the 6 ah battery. With the 7.5 ah battery, I have never used the battery up.
Love your dog .....lol
LOL... Yeah, she loves tall grass and playing around in the woods. Thanks
Great review. Do you know how big (HP or Wattage) the motor is on this unit?
I'm trying to decide between this, Kobalts 40 volt and Ryobis 40 volt. I have a .30 acre lot. What would you go with?
I do have a question I've looked at one of these mowers personally i thought the wheels were flimsy @ 3:09 min on your video it shows what i found the wheels don't seam strong at all .... You can see how they lean in your video .... Awesome review as always !! Just seems like this model was rushed but it does look like dewalt with a few small changes will be a top runner is the battery market !
I did not notice that at 3:09 I just hopped out into the garage and found that nut to be loose allowing the ball bearings to slide around a bit. I feel that these wheels are pretty fair when you compare this to other models in the same price range. If you pay more, you seem to get a more rubber type wheel where this is more like hard plastic.
Hey guys, i need some advice please. Looking at buying the Dewalt DCD796 combi drill. I've got 2 prices - £140 with 2x 4AH batteries or £185 with 2x 5AH. Should i pay an extra £45 for the 2 bigger batteries (1ah difference) just for DIY. What u think?
just got this mower waitn on the battery to charge ,prior i always used a side discharge gas mower for my small town home yard which of the 3 ways do you recommend using this mower ? mulching,rear discharge,or bagging? which way seems to work best? i will post back on my experience and run times once i get it goin thanks for any input on which of the 3 ways works best comming from a side discharge gas mower.
Use it in mulching mode as it seems to be the easiest and best.
ok ive had the mower for a week or so and i really like it,i have found the mulching mode to be the best as you said ,i cut 4 town home lawns front and back and with a 7.5ah battery i get all 4 lawns done but on the last house i get 3/4 the way done on the back lawn and it dies and i throw the included 6ah battery on to finish the last 3 swipes..for my needs it works great,found it at lowes for $299
Any plans to test out the 2 x 20 mower. Curious to see how these two compare.
No, because they are really the same mower. I believe we reviewed the more cost effective and longer running one out of the box. If one were to have larger FlexVolt batteries, that would make the 20-volt be a bit better, but purchasing them for the mower would cost major money.
You have convinced me that Dewalt is not the way to go.
Does this thing have rear drive? I am sorry if you covered it. Second question I see people having fits with the unit getting wet and then it wont start. How is your mower holding up after one year? Looking at one as a gift for a older gentleman that just loves his lawn but has to be careful in not exerting himself. The lawn is smaller but has parts that slope. Thank you in advance. I have a ton of batteries 4, 6's and 9's. Happy to throw in an extra battery for him as long as it is light and easy to push and no problems with the occasional water.
No
Good review Brian. But the dog was my favorite part of the video. #WORKSHOPADDICT
Russ Webster She is a character.
Which mower would you recommend : this Dewalt 40 or Greenworks 60V
Swanzilla I have never used the Greenworks 60v. I have used the Greenworks 82 and it rocked. The only way I would recommend the DeWalt is if you had an extremely small yard. Sorry o cannot give you a solid answer.
how does it Compare to Echo 58v
For bagging you really need a high lift blade, the blades that are on most of today's mowers are what they call a 3 in 1 blade, they don't do any of those tasks very well so its best to have the right blade for your specific type of mowing, whether it be mulching, side discharge, or bagging...side discharge and bagging you really need a good high lift blade to throw those clippings, where with mulching you want the blade to create a cyclonic action to toss the clippings up under the deck and keep doing so to keep chopping them into finer and finer pieces in which a dedicated mulching blade is the way to go.
Could you throw a high lift blade on that lawn mower and do your bagging test again and see what it does?
People got to understand these battery operated mowers are small yards, these are for the yards that you really don't need a gas powered mower but you don't want to use a manual push mower these are perfect for that, the EGO is probably the best for these battery mowers but the Dewalt is definitely the most powerful, the EGO starts off using lower power and than in thick grass it powers up my brother bought the EGO he has small yard and he just is able to finish his yard but if he lets get to long it stalled a lot
Which mower would you recommend the Kobalt 80 volt versus the DeWalt 40-volt? I am on the fence of getting the DeWalt except the run time is what kills it for me. The Kobalt 80 volt has 2 Amp Hour batteries versus the DeWalt has a 6 amp hour batteries
JUAN HERNANDEZ watt hours is what really matters and that is volts x amp hours. So the DeWalt has 40 x 6=240 and the Kobalt has 80x2= 160. One would think from there the DeWalt would be better. If you are researching Kobalt, they are a rebranded Greenworks. A 2Ah battery will also be a 1p battery meaning it only has one set of cell that equal that voltage. The dewat batter could be wired up as 2ah, but it would be 120 volts since it is a 3p battery.
WorkshopAddict dewalt seems to get my attention, I've been looking into the Troy bilt tb510 also for the same price point, 399 dewalt 449 kobalt and 499 Troy Bilt..
JUAN HERNANDEZ Tough call. I would look to EGO for a good battery mower.
WorkshopAddict I will go by my local HD tomorrow and see what they have . I appreciate your response . Thanks for the great videos !
Really surprised they didn't go 60v
60-volt or FlexVolt has fewer cells than the 40-volt, even though it is less voltage. the 9.0 Ah Flexvolt battery is only 3Ah in 60-volt mode.
I picked one of these up on clearance, i can buy 2 additional 7.5ah batteries for 340 putting cost at about 500. I had my eye on the ego 21 self prop which is 499-549 dpeneding on sale. With money being equal, which mower would you pick?
If you need pure power (trimming ditches) with a very short 15 minute runtime, I would go Dewalt. If you are mowing your lawn, I would go EGO.
@@WorkshopAddict is that solely due to run time or something else? Im in houston and with rain we get my st augustine can get a little thick in a short time. Thanks for your help.
There is no doubt that the Dewalt is built more like a traditional lawn mower, but the runtime with it is very short. So, unless you want to invest in many, many batteries and change them every 15 minutes, the Dewalt is not much of a lawn mower and more of a trimmer. The dewalt has mad power. The EGO has a lot more computerized control and has made many, many more lawnmowers. There are small things on the EGO that helps it to perform better. They have a runtime of 45 minutes. I do not know anything about your yard or how you will use this, so I am trying to give you all the general info.
My parents bought me one of these on clearance as a housewarming gift. Couldn't even finish cutting a truly tiny front yard before it was out of power. Had to finish with a little cheesy gas mower that the previous homeowner left with the property. Liked everything else about it up to that point.
how heavy is the weight?
How about two 60 flex-volt batteries for a 120 volt-lawnmower!
Have you looked at kobalts 80v mower? If not please do and share your opinions and thoughts about it.
No, but I do have the new Greenworks 80 volt here for testing. Greenworks makes Kobalt.
Yeah I read that Greenworks is identical to the Kobalt in my research. Looking forward to watching that review. 😀
Greenworks is a solid product for sure. I think you're going to see them as a leader in the industry. They are setting up an assembly plant in USA and are gunning for a USA battery manufacturing plant.
WorkshopAddict, have you tested out the greenworks mower yet?
Will this mower allow you to use flex volt batteries
Yes
20v mower has two 5ah, total 18650 cells 20. 40v mower hay 30 cells with the 6.0 and 7.5 batteries.
Can put DEWALT FLEXVOLT 20V 9AH or 12AH, 2X20V with 9AH or 12AH =40V with 9AH or 12AH
what if you use it with a 60 volt. flexvolt battery
This is Dewalts 40 volt battery. They do not accept 20 volt or flexvolt batteries.
still have my Black n Decker 36v lead acid "self propelled" mower 7 years now and had rebuilt the SLA cells once for $65 very cheap and reliable and no rust as its all plastic except the blade....had picked up 2 more that had been left as trash with dead batteries...I now have 2 spares...dewatls a nice mower but no thanks...I'm ok for another 20+ years...
dewalt needs to make a battery back pack like all these other companies making batter powered tools. imagine putting in in 4 60v flex bolts in a pack to power this thing dang
They did have a 40-volt line for OPE and it did not sell.
@WorkshopAddict
I've almost convinced myself to buy (EDIT: the 2x20V version of) this, but I was planning to use a mix of batteries with it - A new 6Ah FlexVolt, and a collection of 2Ah 18Vs that I already own.
I asked Dewalt and they "advised against mixing batteries", but didn't give any concrete reason. And obviously they're incentivised to get me to buy 2 new FlexVolt batteries :)
Have you tried running with mix-and-match batteries? Did it power the mower? Did it seem to cause any problems for the batteries?
We have mixed batteries, but not a huge swing like a flexvolt and a 2Ah. IMHO, I would mix a flexvolt with a 5 or 6Ah 20V, but a 2Ah battery should never go in this mower. The mower draws too much and will cook those small batteries.
@@WorkshopAddict How do you mean? It would get literally hot? Or just that it'll drain them very quickly? (The latter is what I was expecting)
Are the 2Ah not well-designed for extended drain?
@@Brondahl They would most likely get hot and drain very quickly. They are meant for small tools and light jobs. This is a huge tool. I think you should run this with 2 flexvolts. The amp draw is more than the little batteries can take.
@@WorkshopAddict Thanks for the advice. (For reference, mainly when using other tools ... is the batteries getting hot a *problem*? I've certainly noticed that it if they get hot then they'll stop powering the tool and then if allowed to cool back down continue working. But I've always assumed that wasn't a problem if I had other batteries I could swap them out with. Is that heating damaging the battery and/or tool, long term? Or is it purely a short term impact?)
@@Brondahl batteries will degrade when too hot. We find in our torture testing that we kill batteries about 50 percent faster when we overheat them to thermal cutout 5 to 6 times. Using the right battery on the right tool is important as the amp draw on a single layer battery pack can be very hard on them long term. We have also killed brand new batteries doing what you were suggesting to do.
Ego gets through long grass no worries
I agree and disagree. EGO has a great runtime and a perfect mower for use on a lawn. It does not work great for trimming ditch banks or cutting 18" tall grass. It has good power, just not the power this has.
WorkshopAddict is it because it appears to bog down and rev up. It would be good to compare the actual specs ie the motor rated power. I think the ego is 1000w max power.
Which would you prefer ego 56 or dewalt 40
If I was taking care of a ditch bank and only trimming for a VERY short time, the DEWALT has more power. Overall, if I was using it to cut a yard, you cannot beat the EGO runtime. EGO has a new model coming out with 2 batteries.
Joy Kwiatkowski to y
Uh, 12 minutes on well maintained grass? I live in an end unit townhouse and it takes me longer than that to cut my lawn. I can’t imagine many people cutting smaller lawns than mine.
I can cut my lawn twice on a single charge of my Ego 5Ah battery, though.
superspeeder Yeah, you would need a very small, or micro lawn, to mow everything on one charge with this unit.
I have 36 volt dewalt batterys will it work with these
james jones Are they the old style?
No not the 36v
40V for yard equipment only ( trimmer, hedge, chain saw, blower and mower), 36v for power tools only (drill, rotary hammer, saw, grinder, impact wrench), look different plugs, 36v for other countries than North America
no
Why this model is not self propelled 🤔
it is not too heavy to push ??
It is not heavy to push at all. I have to guess that the self-propelled model would cost more and use more battery. That would raise the price point higher than others on the market and the runtime is lacking.
Your happy dog stole the show fo sho! Mower is almost as bad as their crappy 20V unit though...
Now they are bringing it out in the Craftsman line.
Come on Milwaukee make me a lawnmower and include a 12.0 ah or two.
Two 12Ah would work well. Much less than that and I feel it might not have the power or runtime we all want.
After seeing the 20v version of this mower I think milwaukee should make one that makes 2 m18 batteries into a 36v, 20v doesnt seem to be enough juice
Don't know why anybody makes a steel deck these days. Honda provided years ago that plastic decks can be made to last, and don't rust
Some people did not read that memo yet.... Lots of people think the composite decks suck. Not sure why....
They Should have Gone with 60v !!! or 80 V sys
Why dewalt don’t use extra battery with more charge like on e-bikes. Voltage is not the problem, need more Amps and running time. For me this mower is not an alternative for gas mower. When they design a new deck and big battery, it would be awesome.
Interesting. DeWalt has two nearly identical push mowers, one takes (2) 20V and the other takes (1) 40V battery. They cost the same and they both get similar short run times. Seems very confusing to the consumer. I saw a review of the 20V version on another site and they never even mentioned that there was a 40V single battery version. The built quality does seem nice. It's a shame the batteries are $200.
We opted to go with the 40-Volt version because Dewalt states those are more for commercial users and the 40-volt trimmers are way better than the 20-volt models. This mower is pretty much the same unit, it just has a different battery housing. Everyone is going over the 20-volt model, so we tried to be different.
I really appreciate that you mentioned both mowers and I'm sure others will too. It looks like a single 40V/4AH battery costs about the same as two 20V/5AH batteries. I believe the 20V mower only comes with a single battery charger.
The 20-volt does only come with one charger. The 20-volt does currently have an advantage IF you use two 9.0 or 12.0 Ah Flexvolt batteries, but now that raises the price to well over 600 dollars!!!!!
I really wanna see 2 things the run time of the 20x2 mower with 2 9.0ah flexvolts and also the 40 volt run time with the 7.5ah battery,since you do have the 40 volt mower have you tried it with the 7.5ah battery if so how much longer did it run?
I know I have a 7.5Ah battery, but I could not find it to add it to the review. My bet is that the 9.0 or 12.0Ah batteries in the 20-volt machine would run longer than the 40-volt 7.5Ah.
LOL, just get an EGO and call it a day.
12 minutes? There's others that have triple that run time.
Lord baal Even more than tripple!
I have this mower with the 6Ah battery that came with it and I am getting more like 20 minutes of runtime. My house is on a 1/4 lot and I can cut the front and back yards on one charge. You could upgrade to the 7.5Ah to get more time but the battery alone is around $230.
Dewalt decide on a battery platform and stick to it!
Steve Hasebroock that makes no sense. If you mean ope, The 40v ope is for pros, the 20v line is for diy...the 60v is an upgrade over 20v. If your taking tools, no 20v/18v tool can come close to the 60v line of tools...yes,Not even Milwaukee new line w a 12ah....sorry not close. It’s up to the buyer which line you want to be in....
I can almost guarantee over the years I have bought more Dewalt tools then you. I have been through just about every cordless line they have made, and then been left high and dry when they quit an alleged professional line in the past and let those of us that bought the then pro line without a source for batteries. If the 40 volt is for pros, why are they spending all the money promoting the 60 volt line to the pros. Good as cordless for the jobsite they say.
I now have, if you count the tools I can't get batteries for, about 6 or so different lines of cordless Dewalt tools and batteries. I hope the 20/60volt line sticks, their past history has been if it doesn't sell to their numbers, they dump it and don't care about those that supported the line in the beginning. I get it, technology changes and gets better, but at least support the lines of past at least for a while, so we at least have some chance of wearing the discontinued tools out. Hard to use or wear out when you can't get batteries for them!
I agree with Steve, remember the 24v tools they had about eight years ago? They should have used the 60v batts for the mowers even if it required two of them.
if you're a fanboy and don't know anything about DC motors/batteries.
then yeah, sure.
Even Makita X2 beats Dewalt in a few categories. Chainsaw, Recip, Blower, 1-9/16" SDS Max Rotary Hammer.
Milwaukee is going to beat Dewalt in plenty of categories. And then people will finally have to face the facts that higher voltage doesn't automatically mean it's better.
greenworks makes 80v tools as well.
3-1 ???
Bag, Discharge or mulch
40 volts just does not have the run time of a 56 volt of the same amp hour never mind the power. 12 minutes of runtime is not worth it even if you had 3 batteries set aside most people would still not buy this, its to niche. I think if dewalt ramped down the power setting it would last longer and had a ramp up mode.
You hit it spot on.
3:10 WTF is going on with the rear wheels?!!
Bent
IF you LOOK AT THE STIHL ELECTRIC MOWER RMA510 wheels look the Same !!!!!!!!!!!!!!!
Deck looks the Same !!!!!!!!!! CLONE !!!!!!!!of a Stihl
I don't know that I would go as far to say it is a clone. Stihl has side discharge and a nicer, more adjustable push handle. You might be on to something where they are made by the same company, but not the same machines.
Takes an hour to cut my grass, I will stick with gas engines for now.
Bought this mower it sucks. Motor gave up after one year and dewalt warranty is not good it cost more money to repair. I will never buy battery mower again it doesn’t matter what brand.
