摘要: 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 cutting plane and moving an angular velocity sufficient to sever grass in mowing manner. The has effective length extending the through support tube. rotatable spool carries supply of coiled configuration unwound portion being extended tube into plane. feeding mechanism provides for automatic and/or manually selective rotation feed out upon command preselected increments during operation maintain desired but secure against prevent inadvertent unreeling line.
