ABSTRACT:
A rotary-type lawn mower with a motor driven housing member having at least one flexible non-metallic line projecting radially from its perimeter within a cutting plane and moving at an angular velocity sufficient to sever grass in a lawn mowing manner. The line has an effective cutting length extending from the housing member through a line support tube. A rotatable spool in the housing member carries a supply of the line in a coiled configuration with the unwound portion being extended from the tube into the cutting plane. A line feeding mechanism provides for automatic and/or manually selective spool rotation within the housing member to feed out upon command preselected increments of line during operation to maintain a desired effective cutting length but to secure the spool against rotation to prevent inadvertent unreeling of cutting line.
