If you already own a drawer full of DeWalt 20V MAX batteries, it makes sense to want a lawn mower that uses them too. The honest truth first: every mower in this guide is made by a third-party company, not by DeWalt. Houselife, HEINPRO, GREENFURY, Baikemon and worksky build these mowers with a battery slot shaped to accept DeWalt 20V MAX packs, so you can reuse batteries you already have. None of them includes a battery or charger.
The six models differ in how many batteries they need and how wide they cut: three small 13 to 14-inch mowers that run on one pack, and three 40V mowers with 14 to 19-inch decks that need two packs working together.
DeWalt Battery Compatible Lawn Mowers Compared
| Model | Maker | Batteries Needed | Cutting Width | Cutting Heights |
|---|---|---|---|---|

| HEINPRO Cordless Lawn Mower Compatible (HP-DLM34A-0DB) | HEINPRO | One 20V MAX | 14 inches | 5 positions, 1 to 2.6 in. |
| Cordless Lawn Mower Compatible with Dewalt | GREENFURY | One 20V MAX, 4.0Ah or larger | 13 inches | 5 positions, 0.98 to 2.56 in. |
| HEINPRO Cordless Lawn Mower Compatible (HP-DLM34A-0DB-3) | HEINPRO | One 20V MAX | 14 inches | 5 positions, 1 to 2.6 in. |
| 40V 19″ Cordless Lawn Mower | Baikemon | Two 20V MAX XR, up to 8.0Ah | 19 inches | 6 positions, 0.98 to 2.76 in. |

A few terms explained. “Cutting width” or “deck” is how wide a strip of grass the mower cuts in one pass; wider means fewer passes. “Ah” (amp hours) is the fuel tank size of a battery; a 4.0Ah pack runs longer than a 2.0Ah pack. “40V” mowers use two 20V packs at once for more power. “Mulching” means chopping clippings finely and leaving them on the lawn as natural fertilizer, while “bagging” collects them.

Cordless Lawn Mower Compatible with Dewalt
Best for: Tight corners and small storage spaces
Pros
- Lightest here at 18.7 pounds
- Quick-fold handle
- Mulching and 8-gallon catcher
Cons
- Narrowest 13-inch deck
- Needs 4.0Ah or larger pack
Best for: Small yards with two DeWalt packs
Pros
- 40V from two 20V packs
- Six heights, 0.98 to 3 inches
- 35L grass bag, 22 pounds
Cons
- Holds up to 4.0Ah packs only
- Battery and charger not included
The 40V Cordless Lawn Mower Compatible with DeWalt 2x20V MAX batteries is made by Houselife (model HL-DLM34A-0DB). It needs two DeWalt 20V MAX packs to reach 40V, and the listing warns that the battery compartment only fits packs up to 4.0Ah each. It cuts a 14-inch path with a single lever for six heights from 0.98 to 3 inches, the tallest top setting of the small mowers here.
The listing mentions a copper motor and manganese steel blade, a 35L (9.25-gallon) grass bag and a weight of 22 pounds, and it describes the mower as quiet. It does not state run time. The specs list dimensions of 1 by 1 by 1 inch, which is clearly a data error. It carries a 1-year manufacturer warranty.
This model suits a small lawn owner who has two 4.0Ah or smaller packs and wants the option to leave grass a little longer in summer. If you own only one battery, the HEINPRO or GREENFURY models are the ones that work with a single pack.
HEINPRO Cordless Lawn Mower Compatible for Single-Battery Mowing
Heinpro
HEINPRO Cordless Lawn Mower Compatible with Dewalt 20V MAX Battery
Price and specifications are read from the Amazon product page and can change.
HEINPRO Cordless Lawn Mower Compatible
Best for: Single-battery mowing, alternate listing
Pros
- Runs on one 20V MAX pack
- Brushless motor
- Mulch plug and 35L bag
Cons
- Weight not listed
- 15 to 20 minutes per 4.0Ah pack
Best for: Tiny lawns on a single battery
Pros
- Runs on one 20V MAX pack
- Brushless motor
- Mulch plug and 35L bag
Cons
- 15 to 20 minutes per 4.0Ah pack
- Cuts only up to 2.6 inches
The HEINPRO Cordless Lawn Mower Compatible with DeWalt 20V MAX (model HP-DLM34A-0DB) runs on one battery. HEINPRO lists compatibility with many DeWalt packs, including DCB200, DCB201, DCB203, DCB204, DCB205 and DCB240. It uses a brushless motor, a design with fewer wearing parts that tends to run cooler and quieter than a brushed motor.
It is one of the few listings to state a run time: with a single fully charged 4.0Ah pack, HEINPRO says up to 15 to 20 minutes, covering roughly 1,200 to 1,500 square feet. That is about the size of a small front yard. The 14-inch deck has five heights from 1 to 2.6 inches, and you can mulch with the included plug or collect clippings in the 35L bag. It weighs 17.8 pounds. An odd spec line calls the operation mode “Automatic,” though it is a push mower.
Pick this for a very small lawn when you have only one DeWalt battery. For larger yards, the 40V models cut wider and use two packs.
Cordless Lawn Mower Compatible with Dewalt by GREENFURY for Tight Spaces
The Cordless Lawn Mower Compatible with Dewalt 20V MAX battery is made by GREENFURY (model GF8A131). It runs on one pack, and the listing is firm that it must be 4.0Ah or higher for safe operation, naming DCB204 and DCB205 as examples.
At 18.7 pounds with a 13-inch deck, it is compact and easy to steer around flower beds and slopes. A quick-fold handle helps it tuck away. It has a brushless motor, a five-position lever for heights from 0.98 to 2.56 inches, and a choice of mulching or bagging with an 8-gallon catcher. The listing does not state run time.
This is a good fit for a townhouse lawn or narrow side yard. It gives way to the wider 18 and 19-inch mowers if your grass area is larger. Pair it with a battery edger for crisp borders along paths.
HEINPRO Cordless Lawn Mower Compatible, Alternate Listing
This second HEINPRO Cordless Lawn Mower Compatible listing (model HP-DLM34A-0DB-3) describes the same features as the model above: single DeWalt 20V MAX pack, brushless motor, a 14-inch deck, five heights from 1 to 2.6 inches, a mulch plug and a 35L bag, and the same 15 to 20 minutes per 4.0Ah pack.
The listing does not explain how the “-3” model number differs, and it leaves out the weight and dimensions that the first HEINPRO listing includes. Its color is listed simply as black.
Treat these two HEINPRO listings as near twins. If the features matter more than the model number, pick whichever is available, and ask the seller if you need to know the difference.
40V 19″ Cordless Lawn Mower by Baikemon for Medium Yards
Best for: Medium yards needing wide passes
Pros
- Widest 19-inch deck
- 50L bag, 88% collection claimed
- Accepts packs up to 8.0Ah
Cons
- Heaviest at 30 to 34 pounds
- Not for POWERSTACK batteries
The 40V 19″ Cordless Lawn Mower from Baikemon (model DW18A) has the widest deck in this list at 19 inches. It takes two DeWalt 20V MAX XR batteries of 8.0Ah or less, and the listing notes it is not compatible with DeWalt POWERSTACK batteries.
It has a brushless motor, a central lever with six heights from 0.98 to 2.76 inches, a three-position handle, mulching or bagging with a 50L bag, and an 88% collection rate claimed by the maker. The handle folds fully and a built-in carry handle helps with transport. Weight is inconsistent: the feature text says 30 pounds, while the specs list 34 pounds.
This is the pick for a medium lawn where wider passes save real time. It is the heaviest mower here, so smaller yards are better served by the GREENFURY or HEINPRO.
40V 18″ Cordless Lawn Mower Compatible by worksky for Easy Storage
Best for: Medium yards and quick folding storage
Pros
- 18-inch deck, 7-inch wheels
- 1000W brushless, two speeds
- 40L bag and 1-year warranty
Cons
- Needs two batteries
- Weight not listed
The 40V 18″ Cordless Lawn Mower Compatible with DeWalt 2x20V MAX is made by worksky (model WKS-D430). It needs two batteries and uses a 1000W brushless motor with two constant speeds, 2800 and 3300 RPM, so you can choose a lighter or harder cut.
It has an 18-inch deck, 7-inch wheels, six heights from 1 to 3 inches, and a 40L fabric-plastic grass bag. The iron handle folds flat with quick-release knobs. The listing does not mention mulching or a weight, and it includes a 1-year warranty against manufacturing defects.
Choose this for a medium yard when you want a wide deck plus easy folding. Owners who also clear winter walkways might like a battery-powered cordless snow shovel on the same packs.
How to Choose a Mower for DeWalt Batteries
Count your batteries. One pack means the HEINPRO or GREENFURY. Two packs open up the Houselife, Baikemon and worksky 40V models.
Check battery size limits. Houselife fits up to 4.0Ah packs, GREENFURY needs 4.0Ah or more, and Baikemon accepts up to 8.0Ah but not POWERSTACK. Compare these with the packs you own.
Match deck width to yard size. 13 to 14 inches suits small lawns; 18 to 19 inches suits medium lawns. Only HEINPRO gives a coverage figure: about 1,200 to 1,500 square feet per 4.0Ah pack.
Think about storage and weight. GREENFURY (18.7 pounds) and HEINPRO (17.8 pounds) are the lightest. Baikemon and worksky fold down for sheds and garages.
FAQ
Does DeWalt make these lawn mowers?

Do any of these mowers include a battery?
No. Every listing says the battery and charger are not included.
How long will a mower run on one DeWalt battery?
HEINPRO lists 15 to 20 minutes with one 4.0Ah pack. The other listings do not give run times.
Can I use a 2.0Ah DeWalt battery?
GREENFURY says no, it requires 4.0Ah or more. The other listings do not set a minimum, but small packs will give shorter mowing time.
