DeWalt’s Second Generation Cordless Self-Propelled Lawn Mower Review

Posted on September 10, 2023 by Philbert Jackson

DeWalt Introduces Upgraded Battery-Powered Lawn Mowers

DeWalt’s initial venture into the world of battery-powered lawn mowers had mixed results. With their latest generation now available, we had the opportunity to test the new and improved DeWalt 2x20V Max self-propelled lawn mower to see what enhancements they have made.

Pros: Advantages of the DeWalt 2x20V Max Self-Propelled Lawn Mower

  • Impressive battery life
  • Minimal noise during operation
  • Durable steel deck
  • Versatile 3-in-1 design with side discharge capability
  • True 21″ blade width
  • Equipped with rubber tires
  • Compatible with the entire DeWalt 20V Max system
  • Manufactured in the USA with global materials

Cons: Shortcomings to Consider

  • Unconventional drive system
  • Wider wheelbase requires more overlap than usual
  • Angled handle may not be preferred by everyone

Cutting Force: Power and Performance

To assess cutting ability, we put the mower deck to the test by tackling 4 1/2 inches of grass. The DeWalt 2x20V Max proved to be up to the task with a minimum cutting height of 1 1/2 inches, delivering clean and precise results.

While the mower demonstrated ample power, it is important to note that relying solely on this method for consistent mowing may cause clogging. Lawn mowers, including gas-powered ones, do not possess a strong spring mechanism to consistently clear all the grass. This occurrence is not unusual.

Cutting Quality: Precision and Versatility

The DeWalt 2x20V Max Self-Propelled Lawn Mower offers the convenience of bagging, mulching, and side discharge functionalities. Unlike many battery-powered models that only mulch, this mower caters to a wider range of needs. In areas where grass growth is fast, the side discharge option is especially appreciated.

In terms of cut evenness, the mower performed admirably. Any discrepancies observed were primarily due to insufficient overlapping, rather than human error. The wheelbase, slightly wider than the blade’s width, means that following the tire track precisely can result in missing a small portion of grass.

Run Time: Endurance and Efficiency

One of the major concerns with DeWalt’s first-generation lawn mowers was their limited run time. However, this issue has been successfully addressed in the updated version. During light cutting, the brushless motor powered by two 10.0Ah batteries lasted over an hour. It is worth noting a slight decline in performance towards the end.

For medium-sized lawns, expect a run time of over 45 minutes. With a single charge, this mower is capable of covering most 1/4 acre lawns and even up to 1/3 acre, depending on the grass species.

Design Notes: Features and Ergonomics

Drive System

DeWalt’s drive system for their battery-powered lawn mowers might be perplexing for those accustomed to other models. Instead of a separate motor to drive the wheels, DeWalt employs a more traditional belt system attached to the front wheels. The speed adjustment is achieved by increasing the pressure applied to the pulley via a cable and controller mechanism. No buttons, dials, or sliders are required; simply adjust the pressure on the actuator lever. This system closely resembles the controls found on Husqvarna self-propelled lawn mowers.

Beneath the drive control area, you will find a small dial that allows you to fine-tune the cable tension. By adjusting this dial, you can set the drive lever to engage the pulley at the most comfortable level. On the “slow” setting, the tension on the belt and pulleys is reduced, resulting in slower drive speed. On the “high” setting, maximum belt tension allows for faster speeds.

It is important to note that blade speed increases alongside the hardness of the grass being mowed. In thicker grass, loosening the drive lever slightly will help maintain a manageable pace.

Handle Ergonomics

The latest DeWalt lawn mower features a redesigned handle that tapers at the top. This design forces a grip at an angle, unlike previous models with both angled and flat sections. Our team had mixed opinions regarding the comfort level. If you prefer mowing with your hands on the horizontal portion of the handle, adjusting to the angled handle may require some time.

Steel Deck and Height Adjustment

The DeWalt 2x20V Max Self-Propelled Lawn Mower boasts a sturdy 21 1/2″ steel deck to accommodate the true 21″ blades. This steel deck ensures durability and longevity.

Height adjustment is facilitated through two points—one at the front and the other at the rear. While not as convenient as a single-point adjustment, this configuration offers a unique benefit. By setting the front height slightly higher than the rear, you can enhance bagging efficiency.

Additional Features

The mower can be stored vertically, saving valuable space in your storage area.

DeWalt 2x20V Max Self-Propelled Lawn Mower Prices

The second-generation DeWalt 2x20V Self-Propelled Lawn Mower is currently available at The Home Depot for $479.00. This complete kit includes two 10.0Ah batteries and a charger. Considering the individual cost of a two-pack of 10.0Ah batteries is $349, acquiring a lawn mower and charger for an additional $130 is an excellent deal.

Considering the overall value and features offered by battery lawn mowers, this price tag is highly attractive.

The Bottom Line: Improved Performance and Considerations

The DCMWSP244 is a significant improvement over DeWalt’s initial generation of self-propelled mowers. While there are some areas that could be further refined, and slight design adjustments to acclimate to, the $479 price point makes this mower a compelling option for lawns up to 1/3 of an acre. This is particularly true if you already own other DeWalt 20V Max and FlexVolt power tools and lawn care equipment.
