The 19-inch Black & Decker SPCM1936 is a self-propelled cordless mower that earns top ranking in comparison tests for both ease of use and performance. Weight has always been an issue for cordless mowers, so the variable-speed drive is a real plus for this model. Except for pollution where the battery and electricity are manufactured, this mower is about as "green" as you can get with a lawn mower that's not a manual reel model. You can extend the mowing time (35 to 45 minutes per charge) by switching out the battery, but a full charge takes 12 hours -- so if you have a big yard, consider a budget gas self-propelled mower such as the similarly priced Honda HRR216VKA (*Est. $400).

This is a video ad for the mower, but it does do a good job of demonstrating how the controls and lift-out battery work.
