Abstract
In an electric lawn mower, a rechargeable battery and an electric motor activatable by the battery are mounted in a machine body section, and a cutter blade is provided within a cutter housing and rotatable via the electric motor to cut grass. Cover member collectively covers the battery and electric motor. The cover member is shaped to progressively slant upward in a front-to-rear direction of the machine body section, and the cover member has an opening formed in its lower front end portion and an air vent formed in its rear end portion to thereby permit ventilation from the opening to the air vent such that the battery and electric motor can be cooled by air flows.
