DeWalt 20V MAX XR 21-Inch Brushless Cordless RWD Self-Propelled Lawn Mower Kit with Two 10.0Ah Batteries (DCMWSP255U2)

Maintain your property with the completely redesigned DEWALT mower, built from the battery up for optimal electric cutting performance. The new 2x20V MAX XR rear-wheel-drive self-propelled mower features a patented high-efficiency cutting system that utilizes an all-new steel cutting deck design, dual blade system, and AutoSense motor to deliver up to 80 minutes of runtime using both included batteries in succession. The mower folds with one touch for easy storage and comes with 3-in-1 mulching, bagging, and rear side discharge. The dual blade AutoSense motor constantly adapts power delivery to grass conditions for consistent cutting performance without wasting battery in light grass or bogging down in heavy grass. A single-point height-adjust system offers 6 settings for a variety of grass conditions and cutting preferences, and a speed dial lets you adjust your walking speed with ease throughout the mowing session.

High-Efficiency Cutting System with Dual Blades and AutoSense Motor

The high-efficiency cutting system with dual blades is designed for runtime and cutting performance, distributing the cutting load across two blades for a cleaner, more even finish across the full 21-inch width. The AutoSense motor continuously adapts power output to grass conditions, delivering more torque in heavy or wet grass and conserving battery in light grass — maximizing usable runtime while maintaining consistent cut quality. The 21-inch (533mm) steel cutting deck provides structural rigidity and long-term durability under regular residential and professional use, and the deck is built from metal for sustained performance across multiple seasons.

Dual 20V MAX 10.0Ah Batteries with Up to 80 Minutes Runtime

The mower runs on two 20V MAX XR 10.0Ah batteries included in the kit, delivering up to 80 minutes of runtime using both batteries in succession. Two 4A chargers are included so both batteries can be charged simultaneously between sessions. Because the mower runs on 20V MAX batteries, it's fully part of the DEWALT 20V MAX platform, allowing operators who already own DEWALT 20V MAX tools to share batteries across their entire tool collection. The DEWALT 20V MAX XR platform is DEWALT's professional-grade cordless system, engineered for reliability under demanding use conditions.

3-in-1 Cutting System: Mulch, Bag, or Rear Side Discharge

The mower features 3-in-1 grass management for mulching, bagging, and rear side discharge, giving the operator flexibility to match clipping management to the season and property conditions. The bag fills up to 95% full before needing to be emptied, reducing the frequency of stops during extended bagging sessions and maximizing the time spent actively mowing. A grass bag, rear side discharge chute, and mulch plug are all included, so the mower is ready for any of the three cutting modes out of the box.

LED Dashboard and AutoSense Feedback

The LED dashboard communicates battery state of charge, cutting system difficulty, and blade end of life, giving the operator real-time visibility into mower status and maintenance needs without stopping to inspect components. This is a meaningful operational advantage over mowers without an instrument panel because the operator can see when batteries are running low, when the cutting system is working harder than normal (suggesting taller grass or blade dullness), and when the blade is approaching replacement.

One Touch Storage and Build Quality

The one-touch handle system quickly telescopes and folds the unit between storage and operating positions, and the mower takes up 82% less space in vertical storage compared to its in-operation footprint — a significant advantage for properties with limited garage or shed floor space. The mower is 85% quieter than a comparable gas mower, reducing noise impact during mowing sessions in residential neighborhoods. The 21-inch steel deck provides the durability required for regular use, and the overall platform reflects DEWALT's professional-grade build standards. The machine is backed by a 3-year limited warranty, 1-year free service, and 90-day satisfaction guarantee.
