Cub Cadet RZT S Zero Electric ZTR 22HP Zero Turn Mower
If you are looking for the most eco-friendly ZTR mower available, the Cub Cadet RZT S Zero Electric ZTR can't be beat. Using no gas or oil, just an electric motor with batteries, this mower features standard steering wheel control and 4-wheel steering. With 60 minutes of run time, it would work fine for most suburban yards, and the 42-inch floating deck makes sure you get an awesome cut every time.
This is one of the more expensive mowers on the list, but it’s also the easiest to use. Even the blades are powered by electric motors, so there aren't even any belts to change. The three year warranty assures you this is no flash in the pan electric mower, and it even has a high backed seat for comfort. If it were priced less and had a bit more range before recharging, this mower would be at the top of our list.
