A cutting apparatus including a plurality of rotating laser beams for cutting vegetation. The apparatus comprises a housing including side walls being extended generally perpendicular to form a downwardly oriented opening. An electrically powered laser cutting device is rotatably positioned centrally within the housing. A transport device is connectable to the housing to provide movement of the housing and laser cutting device along a surface covered by vegetation. The laser cutting device generates at least one laserbeam that is continuously rotatable in a 360.degree. arc underneath the housing, with the at least one laser beam being adjustable in angular direction to direct laser beams in a plurality of angles arcing downwardly across the vegetation being cut. The speed of rotation of the one or more laser beams increases proportionally as ground speed increases for the cutting apparatus to provide adequate cutting of surface area in proportion to the ground speed across the vegetation. A plurality of rotating pairs of laser beams can be generated and separately angled downward at angles other than horizontal, providing cutting paths across the vegetation at different heights during each rotation, thereby creating variable length cut vegetation that provides aesthetics for the cut vegetation, and provide clippings of variable lengths for improved mulching and decomposition of the cuttings.

[ What is claimed is:] [1.]1. An apparatus for cutting vegetation, the apparatus controlled by a user for movement along a surface covered by vegetation, said apparatus comprising:a housing including a first surface and at least one side wall being extended generally perpendicular and downwardly from said first surface, said housing having a second surface being faced in an opposed direction from said first surface, said housing having an opening being positioned downwardly and being bound by said at least one side wall, said opening being positioned proximate the vegetation being cut during operation;a laser cutting means being powered to be rotatable while being positioned on said second surface within said housing;at least one laser beam being generated by said laser cutting means, said at least one laser beam being rotatable during operation of said apparatus for cutting vegetation positioned proximate within said opening;a control means positioned proximate said housing, said laser cutting means being controlled by said control means for speed of rotation and angular direction of said at least one laser beam;a power means being detachably connected to said housing, said power means provides power to said laser cutting means; anda transport means being connectable to said housing, said transport means being movable by the user at a variable speed along the surface covered by vegetation while said laser cutting means and at least one laser beam rotates within said housing.
