Description
Product Overview
The DEWALT 21.5 in. 20V MAX Self-Propelled Lawn Mower* is built for serious performance and efficiency. Powered by a high-efficiency brushless direct-drive motor, this mower delivers up to 60 minutes of runtime using two 10.0Ah 20V MAX* batteries (DCB210) — perfect for small to mid-sized yards up to 0.5 acres.
This mower features auto-sensing technology that automatically increases motor RPMs when cutting thick or dense grass, ensuring a clean, even cut. Whether you're mulching, bagging, or using the side discharge, you’ll get versatile performance with the included 3-in-1 cutting system.
Designed with convenience in mind, the adjustable self-propelled drive system and fold-over handle make mowing and storing easier than ever. When stored vertically, this mower saves up to 70% more space in your garage.
