Abstract
In an electric lawn mower, a cutter housing includes a support plate portion for mounting an electric motor. The electric motor is disposed at a substantially central portion of the cutter housing and is connected directly to a cutter. A scroll portion is bulged from an outer edge of the support plate portion on either the left or right side of the electric motor and is sloped up rearwards. The scroll portion is formed into such a shape that it widens as it becomes closer to a discharge port at a rear of the cutter housing. Batteries are mounted on the support plate portion in an arrangement such that one of the batteries extends along an inner side of the scroll portion. The electric motor is sandwiched between front ends of the batteries. Thus, the lateral weight balance of the cutter housing is substantially uniform to enhance the travelability. Furthermore, the cutter housing is made compact.
