In-Depth Reviews: The 5 Best DeWalt Lawn Mowers for 2026
1. DeWalt 20V MAX 21.5″ Self-Propelled: Best Overall
If you want the ultimate balance of power, runtime, and ease of use, this is the flagship model to get. Operating on two 20V MAX batteries, its high-efficiency brushless motor delivers consistent torque even in overgrown grass. The self-propelled feature takes all the physical strain out of mowing, making it perfect for medium-to-large suburban yards.
- ✅ Effortless rear-wheel self-propelled drive system.
- ✅ Large 21.5-inch steel deck reduces the number of passes.
- ❌ Heavier than standard push models.
2. DeWalt 2x20V MAX 20″ Push Mower: Best for Small Lawns
Not everyone needs a self-propelled motor. If you have a flat, smaller yard, this DeWalt push mower is incredibly lightweight and highly maneuverable around garden beds and trees. It folds over completely for compact vertical storage in tight garages.
- ✅ Extremely lightweight and easy to push manually.
- ✅ Excellent space-saving vertical storage.
- ❌ The 20-inch deck means slightly more walking compared to larger models.
3. DeWalt 60V MAX FLEXVOLT 21″: Maximum Cutting Power
For homeowners dealing with thick, wet, or exceptionally dense grass, 20V might not cut it. The 60V MAX FLEXVOLT mower offers gas-like performance without the fumes. It features an auto-sensing brushless motor that automatically increases RPMs when it detects heavy resistance.
- ✅ Unrivaled power for an electric mower; rivals 160cc gas engines.
- ✅ Auto-sensing technology optimizes battery life.
- ❌ The premium price point.
4. DeWalt 20V MAX 21″ FWD Mower: Best for Hilly Terrain
While most self-propelled mowers use rear-wheel drive, this model utilizes a front-wheel-drive (FWD) system. This is fantastic for yards with a lot of obstacles or slight inclines, as you can simply tip the front wheels up to disengage the drive and easily pivot around corners.
- ✅ FWD allows for fast, sharp turns around landscaping.
- ✅ Smooth, variable speed control.
- ❌ Can lose traction if mowing uphill with a full bagging attachment.
5. DeWalt 20V MAX 3-in-1 Cordless: Best Budget Option
If you already own plenty of DeWalt 20V batteries from your drills and saws, buying a “bare tool” (mower only, no batteries included) is the best way to save money. This 3-in-1 model allows you to mulch, bag, or side-discharge your clippings, offering great versatility at an entry-level price.
- ✅ Highly affordable if you already own DeWalt batteries.
- ✅ Versatile 3-in-1 clipping management.
- ❌ You will need to purchase batteries and a charger separately if you don’t have them.
Frequently Asked Questions (FAQ)
Who makes DeWalt lawn mower engines?
Because modern DeWalt lawn mowers are entirely battery-powered (electric), they do not use traditional gas engines. Instead, DeWalt manufactures its own highly efficient, proprietary brushless electric motors. These electric motors are designed to be maintenance-free, offering long lifespans without the need for spark plugs or air filters.
What oil does a DeWalt lawn mower take?
One of the best benefits of upgrading to an electric DeWalt mower is that they do not take any oil at all! There is no engine oil to check, add, or change. The only maintenance required is keeping the cutting deck clean and occasionally sharpening or replacing the steel cutting blade.
Why is my DeWalt lawn mower not working?
If your DeWalt electric mower won’t start, check these three common issues first: 1. Safety Key: Ensure the red plastic safety key is fully inserted into the slot near the battery compartment. 2. Batteries: Make sure both 20V batteries are fully charged and firmly clicked into place (most models require two batteries to run). 3. Handle Position: The telescopic handle must be fully extended and locked into the correct operating position; otherwise, a safety switch will prevent the motor from turning on.
