Professional Tool Reviews for Pros


DeWalt 20V Cordless Lawn Mower | Gen2 with 10Ah Batteries


DeWalt Next-Gen Mowers Deliver High Voltage Cutting

Next-generation DeWalt 20V Cordless Lawn Mower models are coming. Like any next-gen model, the lineup shows some marked improvements in several key areas. In this case, DeWalt has tweaked the old design for more power, as well as some multifunctionality in how you manage your clippings. Both the DeWalt DCMWSP244U2 self-propelled lawnmower and the DCMWP233U2 push mower look like huge improvements from where we stand.

DeWalt Gen 2 Mower Key Features

The DeWalt 20V Max Cordless Lawn Mower models operate on the brand’s 20V Max battery platform, utilizing a dual battery system. This time, however, they come kitted with two 10Ah batteries. That should “math out” to packs with 180 Watt-hours each. These packs also look like they use the newest battery cells that generate 5Ah per layer. In theory, that could lead to 20V packs as large as 15Ah in the future, provided they can cool them sufficiently.

These next-gen cordless mowers use DeWalt’s auto-sensing technology. This lets the mower run the blade at higher RPM when needed. When performing a maintenance cut, the RPMs run lower, extending your runtime.

DeWalt 20V Self-Propelled Mower Run-Time

Speaking of runtime, what can we expect here? The original DeWalt DCMW220P2 2x20V lawnmower lacked in the runtime department. DeWalt claims that the new Gen 2 2x20V self-propelled mower can cut for up to 60 minutes on two 10Ah batteries. Meanwhile, the 2x20V Max Push Mower delivers up to 75 minutes of runtime per charge.


Those numbers actually come qualified. DeWalt specifies them when cutting 1/3 of the grass height on height setting 6. Translated into area, DeWalt estimates either model can tackle up to half an acre before having to recharge the batteries.

Steel Cutting Deck with Side-Discharge

Both DeWalt 20V Max Cordless Lawn Mower models feature 21-1/2″ steel cutting decks that you can adjust via the dual lever cut height adjustments. We like how one lever comes positioned on a front wheel and the other in the rear. It looks to balance some of the potential for flexing. You have six height positions, and they adjust between 1.5 to 3.75-inches.

All battery-powered lawn mowers we’ve reviewed to-date include the option to bag grass clippings. Most mowers also include mulching. Not all, however, include side discharge.

One of the improvements DeWalt made in their Gen 2 20V Cordless Lawn Mowers is they include the option to mulch, bag, or use a side discharge chute for grass clippings. We like that they added back in that third option.

Folding Handle for Storage

When you finish up mowing, the handle on the DeWalt 20V Cordless Lawn Mower folds over for easy storage or transport. In our experience, these tool-free folding handles make these mowers easy to pick up and put in a truck or store vertically in a shed or garage.

Pricing and Availability

These 2nd-generation DeWalt 2 x 20V Max Cordless Lawn Mowers hit stores in Q1 2021. Each comes kitted with two 20V Max 10Ah batteries and two DCB107 1.25A chargers. The DeWalt DCMWSP244U2 self-propelled mower retails for $549. The DCMWP233U2 push mower prices out at $399. Both options include DeWalt’s 3-year warranty, 1-year free service agreement, and 90-day money-back guarantee.

Considering the size of the batteries, and what they’d typically go for all by themselves, the prices here feel downright reasonable. For DeWalt users, this also seems like a good opportunity to score some high capacity batteries while getting into the joys of battery-powered mowing. For folks not yet on DeWalt’s 20V platform, this might be a cost-effective way to get started.

Interesting – DCB107 is not found at: https://www.dewalt.com/products/accessories/batteries-and-chargers/chargers A dual simultaneous charger might have been better. DCB102 12V – 20V MAX* JOBSITE CHARGING STATION There is also the 4 port DCB104 MULTIPORT SIMULTANEOUS FAST CHARGER My opinion and experience with several brands of battery OPE over multiple years – you need to have a fast enough charger that you only need 2 sets of batteries. What I really like about this DeWalt – the 3 discharge options. I nomally bag our lawn clippings. We also correctly cut our grass high. We have the space to mulch the clippings and don’t… Read more »
