I'm in my second year with a 21-inch cut,Kobalt,80-Volt,steel deck mower from Lowes.We have 40-acres of park and trails where I live and I've mowed many acres a day,alternating rest breaks/cool downs,with charging.I carry the spare battery in my carpenters tool belt along with a water bottle.By the time I've depleted both Lithium batteries (about an hour and a half) I'm ready to go to the house and get out of the heat while the batteries recharge.It's different from my Honda mower,but the electric is much lighter,does everything the gas mower did,is great on hilly terrain,and a lot easier on my worn out body.I'm on a wind power option from my electric coop,and I feel better about the zero-carbon.Don't miss carrying a gas can to town either!
