Design & Build Quality

The handlebar can be adjusted to suit users of different heights, allowing you to maintain proper posture while operating the mower. Anti-vibration technology helps dampen motor vibrations from reaching your hands. Overall, the mower feels robust yet comfortable thanks to its smart design and choice of quality materials.

Cutting Deck

The DEWALT DCMWSP255U2 electric lawn mower has a 20-inch steel cutting deck. The large cutting width makes this mower suitable for mowing lawns up to a quarter acre. The cutting deck uses two precision-cut blades made from hardened steel, delivering efficient cutting and a crisp cut quality.

The dual blades are designed to lift grass up vertically for an even cut. The blade housing is deep to allow plenty of clippings circulation. This prevents any buildup of grass inside the deck while mowing.

Cutting height is adjustable between 1-3/4 inches to 4 inches, in 1/4 inch increments. The single point height adjustment lever makes it fast and easy to raise or lower the deck. At the lowest setting, the mower cuts grass very short for a tidy, manicured appearance. The 4-inch maximum cutting height allows you to maintain longer grass when desired.

Motor & Battery

The DCMWSP255U2 electric mower features a brushless motor that provides ample power and performance for residential lawn mowing. The motor delivers consistent power and torque to tackle both flat lawns and slight hills without bogging down.

The mower comes equipped with two 5Ah 20V MAX lithium ion battery packs. Each fully charged battery provides sufficient run time to mow up to 4,000 sq ft of grass. With two batteries, you can essentially double the run time for larger lawns. The batteries recharge fully in about 60 minutes.

The dual battery system is convenient, allowing you to charge one battery while using the other. This minimizes downtime between charges. The batteries also feature fuel gauge indicators so you can monitor remaining run time.

Overall, the 20V MAX motor and 5Ah batteries offer reliable performance for mowing medium to large sized lawns on a single charge. The dual battery system extends run time for increased productivity.

Self-Propelled Drive

The DEWALT DCMWSP255U2 lawnmower features a brushless self-propelled system that assists the user in moving the mower across the lawn. The mower uses a rear-wheel drive design with two high-powered motors located at the rear wheels to provide forward propulsion.

Variable speed control allows the user to adjust the mowing pace from 0-3.5 mph to match their walking speed and comfort level. The drive system provides consistent speed even when working on hills or uneven terrain. The powerful motors can tackle inclines up to 20 degrees without issue. Owners report the mower handles thick grass and small hills with no noticeable loss of speed or performance.

The variable speed settings allow users to slow the mower down when needed for maneuverability around landscaping and other obstacles. The mower handles tight turns well thanks to its dual rear wheel drive design. Many owners love the versatility of having a self-propelled system for large open areas combined with precise manual control when needed.

Ease of Use

The DEWALT DCMWSP255U2 mower scores very high when it comes to ease of use. Its intuitive controls make it straightforward to operate even for first-time users. There is a single handlebar with an easy-to-read LED display panel showing battery life, speed setting, and status indicators. The primary controls are right at your fingertips, including buttons to adjust the cutting speed, a safety lock trigger under the handlebar, and a single tap lever to adjust the cutting height.

Folding and unfolding the mower is quick and simple with its 2-step process. When folded, it stands upright on its own and has a convenient carrying handle to move it into storage. The assembly out of the box is also fast and uncomplicated. It arrives mostly assembled, requiring just a few steps like attaching the catcher, handlebar, and battery. The included manual has clear instructions and visuals to guide you through the quick and simple setup.

Overall, the well-designed controls, effortless folding system, and minimal assembly required make this an exceptionally easy electric mower to use right out of the box.

Noise Level

Electric mowers are significantly quieter than gas-powered options. The DEWALT DCMWSP255U2 operates at 84 dB(A) sound pressure and 96 dB(A) sound power, which is comparable to the volume of a garbage disposal or blender.

Gas mowers can reach noise levels over 100 dB(A), similar to a chainsaw or motorcycle. The quieter operation of electric mowers reduces noise pollution and hearing damage risk. You can mow early in the morning or late evening without disturbing neighbors.

Some key advantages of the quiet performance:

• Converse with someone nearby while mowing
• Listen to music or podcasts with headphones
• Use hearing protection less often
• Less stress for pets and wildlife
• Overall more pleasant experience

While not silent, the brushless motors minimize noise and vibration. When combined with the lack of gas engine clatter, electric mowers like the DEWALT DCMWSP255U2 offer a peaceful cutting experience.

Safety Features

The Dewalt DCMWSP255U2 electric lawn mower has several important safety features to protect the user during operation.

• The mower has a large red power button that must be held down to start the mower. Releasing this button will immediately stop the mower blade. This prevents accidental starting and allows you to quickly stop the blade.

• There is a blade brake clutch that brings the blade to a fast stop when the mower power is turned off. This prevents the blades from continuing to spin once the mower is powered down.

• To protect your hands from the spinning blade, there is a sizable hand guard that extends from the top of the mower deck. This provides an extra barrier around the front of the mower to keep your hands safe.

• Additional safety mechanisms include rear locking wheels to prevent unintended movement and anti-kickback wheels up front. The wheels are designed to prevent the mower from violently jerking forward if the blade gets obstructed while cutting.

Maintenance

The DeWalt DCMWSP255U2 is designed for easy maintenance to keep it running smoothly over time.

Cleaning - The two-piece deck design allows quick access to the mower blades for cleaning. Simply remove a few screws to detach the deck and clear away clippings. Regularly hosing off the underside keeps grass from building up and affecting cutting performance. The washout port also sprays water right onto the blades for fast rinsing.

Blade Sharpening - Maintaining a sharp blade is essential for a clean, even cut. The blades can be removed without tools for sharpening or replacing. DeWalt offers replacement blades specially designed to fit this mower. Sharpening every 1-2 months ensures optimal cutting.

Battery Care - The dual 20V lithium ion battery packs should be stored indoors and charged fully before winter storage. Avoid leaving batteries in cold temperatures when not in use. The batteries can be charged separately or together on the dual port charger. Proper care extends overall battery life.

Serviceability - This mower is designed for easy DIY service. The two-piece polymer deck allows access to the blade, belt, and other components without needing to tip the mower. Basic maintenance like oil changes, filter replacement, and spark plug service can be performed at home. The manual provides guidance for self-service. For more complex issues, DeWalt has a network of authorized service centers to perform warranty repairs.
