Design & Build Quality

The DEWALT 20V Max lawn mower has an exceptionally sturdy design and is built to last using high-quality materials. The deck is made from durable stamped steel that can withstand impact and is resistant to rust and corrosion.

The handle features a rugged tubular steel frame with an ergonomic soft grip, providing comfort and control while mowing. It folds down easily for compact storage.

The mower sits on 10” rear wheels and 7” front wheels, with durable plastic treads that provide good traction on uneven terrain. The wheels are designed to roll smoothly and easily over lawns.

Overall, the build quality is very robust with the use of sturdy steel in the deck and handle. This is a mower built for heavy-duty yard work and designed to provide years of reliable service. The high-end materials like steel and soft grip padding make the mower feel solid and substantial.

Cutting Deck

The Dewalt DCMWSP244U2 features a 21.5 inch wide stamped steel cutting deck that provides excellent cutting width to handle larger yards efficiently. The deck is designed for durability and corrosion resistance.

While the cutting height is not adjustable on the go, it can be set to one of 7 positions ranging from 1-3/4 inches up to 4 inches using a single lever. Adjusting the cutting height is quick and simple without tools required. The range of height settings enables customizing the cut to your preferences and needs. Most users find the 3-1/2 inch setting optimal for a clean cut with this mower.

Overall, the 21.5 inch wide cutting deck combined with the 7 position height adjustment provides the versatility to handle lawn cutting needs for different yard sizes and grass types. The metal construction also ensures lasting performance season after season.

Drive System

The DEWALT DCMWSP244U2 electric lawn mower features rear wheel self-propulsion for enhanced maneuverability when mowing. This allows the user to adjust the speed based on their walking pace, avoiding the need to constantly push the mower.

The speed control is variable, with two speed options to choose from. There is a slower speed setting for meticulous trimming and edging, and a faster speed for quickly mowing larger areas. Switching between speed settings is seamless and simple with an easy-access lever.

At the higher speed setting, the self-propel allows the mower to keep up with a normal walking pace on flat ground. It doesn't feel like you are exerting extra effort pushing the mower, it glides along smoothly keeping pace. This makes mowing large yards much less tiring.

The rear-wheel drive design also aids maneuverability in tight spaces and around landscaping features. The front caster wheels swivel easily while the rear wheels propel and turn the mower. This makes precise trimming and turning simple without having to wrestle the mower into position.

Overall the self-propel system with variable speed control makes operating the mower almost effortless. By matching the speed to your walking pace, mowing even large yards can be accomplished quickly and easily without becoming exhausted.

Battery & Charger

The DCMWSP244U2 mower comes with two 5Ah 20V MAX lithium ion batteries. Lithium ion batteries offer longer runtime and better performance compared to traditional lead acid batteries. They also hold their charge well when not in use.

The 20V MAX batteries provide sufficient power for the 21.5 inch cutting deck. Dewalt claims they offer up to 45 minutes of runtime, but real world results are closer to 30-35 minutes depending on your grass conditions. The batteries reach full charge in 60-90 minutes.

It's convenient that the mower comes with two battery packs. You can keep one charging while using the other, essentially doubling your mow time before needing to pause to swap batteries. The batteries are also compatible with other Dewalt 20V MAX tools, adding even more versatility.

Some users wish for a single larger battery to extend runtime further to 60+ minutes. But the two pack design provides other benefits like always having a spare ready to go. Overall the 20V MAX system balances power, runtime and convenience quite well.

Noise Level

The DEWALT electric lawnmower has very low noise levels compared to traditional gas mowers. Electric mowers operate much more quietly since they do not have loud gasoline engines.

Gas mowers can produce over 90 decibels of sound. Prolonged exposure to noise levels above 85 decibels is considered hazardous and can lead to gradual hearing loss over time. In contrast, the brushless motors used in electric mowers like the DEWALT emit under 80 decibels. This makes extended mowing sessions much more comfortable without having to wear hearing protection.

The quiet operation is a major advantage, making electric mowers a great option if you have close-proximity neighbors. The DEWALT operates quietly enough to hold a normal conversation near it without raising your voice. This allows you or your landscaper to mow early in the morning or late in the evening without creating noise complaints.

Maneuverability

The DEWALT DCMWSP244U2 is extremely lightweight for a 21.5 inch self-propelled mower, weighing just 72 pounds. This light weight makes it highly maneuverable, allowing you to easily steer and turn the mower with one hand.

The turning radius on the DCMWSP244U2 is also excellent, rated at zero turn. This means it can pivot right around on a dime and maneuver easily in tight spots that would be difficult for a traditional gas mower to access. With the small turning radius and light weight, you'll have no issues cutting around landscaping, trees, or other obstacles in your yard.

Grass Cutting Performance

The DeWalt 21.5 inch cordless mower delivers excellent grass cutting performance. It uses a twin, 3-blade system to produce a very clean cut quality. The blade design and high torque brushless motor enable the mower to cut through thick and dense grass with ease.

The high airflow produced allows grass clippings to circulate freely underneath the deck for efficient mulching. Reviewers comment that the cut grass is so finely mulched that visible clippings are practically eliminated. This eliminates the need for bagging and leaves the lawn with an even, well manicured appearance after mowing.

The mower can cut grass up to 7 inches tall, allowing the user to skip more frequent mowings if needed. Overall many reviewers state this is one of the best cutting electric mowers available. It rivals gas mowers in terms of power and leaving no visible clumping on the lawn after mulching.

Ease of Use

The DEWALT 20V 21.5 inch DCMWSP244U2 electric lawn mower has been designed for easy operation and maintenance. The controls are intuitive with a single button to start the mower and levers to adjust the cutting height between 1-3/4” to 4”.

Folding the handle requires pulling an easy to reach handle in the center which allows it to fold vertically for compact storage. The two part polymer deck also enables the mower to stand vertically on end taking up less space.

Maintenance is simple with no oil changes required and lubricated rear wheels that don't need servicing. The polymer deck is rust resistant and features washout ports that enable you to attach a garden hose to easily clean out grass clippings. The blade can be accessed easily by removing 2 screws when sharpening is required.

The battery charger has indicators to alert you when charging is complete or if there is an issue. Run time from a fully charged 5AH battery is around 45 minutes allowing cutting of up to 1/4 acre.

Overall the mower has been designed to be very easy to use, store and maintain compared to gas mowers. The intuitive controls, vertical fold ability and washout deck make it very simple for the average homeowner to operate.
