My mom wants an electric lawn mower. Any reccomendations?

Also, look at the accessory tools that particular company handles and can you buy "tool only". Mom might need a string trimmer or a blower for her deck and sidewalks. A friend has bought 4 or 5 different cordless tools. Every battery and charger are different. Nothing interchanges. :BangHead: :BangHead: :BangHead: :lol:
