Abstract
A lawn mower using flexible nonmetallic filaments as cutting elements is disclosed. The filaments are mounted on a plurality of rotatable mounting elements. Each of these mounting elements is rotatable about an axis which is slightly tilted with respect to the vertical. The axes of rotation of the mounting elements are so disposed that the filaments appear to travel through overlapping paths when the lawn mower is viewed in top plan. With respect to the normal forward direction of travel of the lawn mower, the axes are 'staggered', one of the axes being forward of the other axis.
