If you prefer cordless but hate the smell of petrol fumes then look no further and get yourself a battery powered lawn mower. Avoid the risk of cutting the cable while keeping the air pollution free. With twin blade design, finer clippings can be produced. And as you know, smaller cuttings break down easily. The smaller cuttings allow the container bag to hold more. When fully charged, the 40 volt battery can run the mower for up to 70 minutes. With the dual battery design concept, you can take advantage of carrying both batteries onboard while mowing. Includes 2 batteries and a charger. If one battery runs out of power, the mower simply switches over to the second one.
