Greenworks 20-Inch 40V Twin Force Cordless Lawn Mower, 4.0 AH & 2.0 AH Batteries Included 25302
Used for one season for our front and back yard, but just moved and now need a riding mower as we have a huge yard now. This thing is extremely quiet and runs for a surprisingly long time on the 2 batteries provided. If for some reason you needed more power, you could just buy another battery and increase run time. Comes with charger and is ready to go immediately. Retails for 350 on Amazon.
