Dewalt 2x20V MAX 21 in. Cordless Battery Powered Push Lawn Mower Kit with (2) 10 Ah Batteries and Chargers. This is not the "self-propelled" model
Brand new, never opened. Previous model got recalled so they sent me this one as a replacement. While I used that one I found it very easy to maintain. Batteries held a charge through my entire front and back yard. Runs much quieter than gas powered.
