Top Picks Of DeWalt Lawn Mowers
DeWalt XR 48cm 36V Mower Kit
You get a high-value package with two 5.0Ah batteries and a charger that extends runtime and reduces setup friction. The XR electronics and brushless motor give dependable power and fine control across different grass types.
Purpose and overview
This fully supplied XR kit is designed to offer a practical middle-ground: more power and runtime than entry-level battery mowers, but quieter and lower-maintenance than petrol alternatives. It’s marketed to cover lawns up to roughly 800 m² depending on conditions and battery usage.
Key features and benefits
The integrated dashboard that displays each battery’s charge level helps you plan mowing sessions and judge when a swap is needed. Multiple user reports praise the cutting consistency and how the motor adapts to grass density — even damp conditions are handled better than expected for a battery mower.
Practical insights and limitations
Who this is for
Choose this kit if you want a ready-to-run DeWalt XR solution with strong runtime and professional-feeling controls. It’s especially useful when you value reliable battery indicators and a brushless drive system that adapts to lawn conditions.
DeWalt Twin 18V/36V 48cm Mower
You get a robust, metal-deck mower that handles longer or damp grass better than many battery alternatives. It’s a practical choice if you already own DeWalt batteries or want a powerful, quiet alternative to petrol mowers.
Purpose and overview
This bare-unit DeWalt cordless mower is aimed at users who want petrol-like performance without fumes or constant maintenance. It uses two 18V batteries in series for 36V output and pairs a brushless motor with a 51cm metal deck to deliver stable, consistent cuts across medium to large lawns.
Key features and benefits
The metal deck and heavy construction help the mower stay stable while cutting, and users report good results even with slightly damp grass. If you already own DeWalt batteries (especially higher-capacity FlexVolt packs), you’ll find run-time and power adequate for many yards.
Practical insights and limitations
Who this is for
You should consider this model if you want a heavy-duty cordless mower and can supply your own DeWalt batteries. It’s best for larger suburban lawns where durability and cutting consistency matter more than lightweight portability.
DeWalt DCMW564P2 51cm Brushless Mower
You get a complete package with two batteries and a charger, which simplifies setup and first use. It’s a solid, well-built mower that suits medium lawns but pay attention to expected battery runtime for larger jobs.
Purpose and overview
This DeWalt DCMW564P2 kit bundles the mower with two 18V 5.0Ah batteries and a multi-voltage charger so you can start mowing immediately. It’s built around a 51cm metal deck and a brushless motor for efficient cutting and durability.
Key features and benefits
Users appreciate the convenience of a complete kit and the mower’s cutting performance. For typical medium suburban lawns the battery set is often adequate for a full session, but heavier, longer grass will noticeably reduce runtime and may require recharge or an extra battery set.
Practical insights and limitations
Who this is for
You should pick this if you want an out-of-the-box cordless mower solution that balances convenience and cutting power for medium-sized lawns. It’s a practical choice when you don’t already own DeWalt batteries and want a ready-to-run package.
DeWalt Self-Propelled XR Brushless Mower
You benefit from assisted propulsion and a high-efficiency brushless motor that can extend runtime with larger batteries. It’s a capable model for bigger areas, though weight and occasional mixed feedback on electronics are considerations.
Purpose and overview
The self-propelled DeWalt XR mower is targeted at users who need assistance when mowing larger or uneven lawns. With self-propulsion and the option to use high-capacity 10.0Ah batteries, it’s intended to cover much larger areas on a single charge than the non-propelled models.
Key features and benefits
Owners praise the increased productivity on bigger lawns and the relief of assisted drive on steeper gradients. If you value eliminating petrol and want an electric mower to replace a large petrol unit, the self-propelled model brings you closer to that experience.
Practical insights and limitations
Who this is for
This mower suits you if you have a larger garden or hilly terrain and want assisted propulsion plus the option to run long sessions on large XR batteries. If you prioritize very light weight or are after the lowest cost option, a simpler non-propelled model may be a better fit.
How to choose and use a DeWalt mower
Match battery system to your needs
You should prioritize battery capacity and count over peak voltage alone. The DeWalt XR 48cm 36V kit includes two 5.0Ah cells and a charger — that combination reduces downtime and is the most convenient purchase if you don't already own DeWalt batteries. If you already have multiple 18V packs, the Twin 18V/36V model can be more cost-effective and still deliver strong performance.
Consider deck size and construction
A 48–51cm (about 19–20") deck is the sweet spot for many suburban yards — big enough to cut swaths efficiently without being unwieldy. Metal decks (like the Twin 18V/36V) stand up better to rough use and damp conditions. Plastic or composite decks are lighter and resist corrosion, but expect different long-term durability.
Brushless motors and self-propel features
DeWalt brushless models (XR and many of the newer variants) deliver better energy efficiency and torque. If your yard has slopes, uneven ground, or you value reduced effort, self-propelled units are worth the tradeoff despite added weight. For flat, fenced-in lawns, a push mower with good battery capacity will usually suffice.

Use these decision points to match a mower to the shape and demands of your yard rather than shopping by rating alone. That keeps runtime, cut quality, and durability aligned with how you actually mow.
FAQs
Runtime depends on grass height, cut setting, and terrain. With two 5.0Ah batteries included, expect significantly longer continuous mowing than a single battery setup—enough to cover most medium lawns on one charge. If you have a very large property, budget extra batteries or plan charging breaks.
Yes. The Twin 18V/36V design accepts DeWalt 18V cells paired to form the 36V system. That makes it economical if you already own DeWalt batteries—just check battery age and capacity for best performance.
Yes. Brushless motors are more efficient, run cooler, and give better torque under load than brushed motors. That translates to longer runtime per battery and steadier cutting performance in denser grass.
Only if you have a larger yard, slopes, or rough ground where push mowing becomes tiring. Self-propel reduces physical effort and keeps an even pace, but it adds weight and sometimes complexity to the drivetrain.
Store batteries at about 40–60% charge in a cool, dry place. Clean the deck after use, remove debris from vents, and check blades for sharpness. For long-term storage, remove batteries from the mower and charge them periodically per manufacturer guidance.
