Abstract
A rotary-type lawn mower is provided with cutting means comprised of a rotatable disc-like member having a plurality of flexible non-metallic cords projecting radially from its perimeter. The disc-like member is rotated within the cutting plane by a suitable power source such as a conventional gasoline-driven engine, and at a velocity such that the projecting cords function to sever the grass in a substantially conventional manner. The cords are therefore of a length and diameter which are functionally related to effective cutting and are mounted within the disc-like member in brackets formed to support the cords against vertical as well as lateral deflection resulting from contact with the grass sought to be cut.
