The Cub Cadet CC30 E rear engine riding mower is completely battery powered, no engine at all! It features a 56V lithium ion battery and a brushless electric motor. The CC30E cuts about one acre per charge, so it is recommended for small yards. The lithium ion battery technology provides consistent, full-powered performance without fading. This compact design offers zero emissions and is up to 54% quieter than the typical mower.
