Abstract:
A lightweight lawn trimmer, mower, and edger system for facilitating the safe and convenient cutting of grass, trimming, and edging of soil comprising, in combination;an aluminum cylindrical support bar having an upper end and a lower end; a molded plastic power grip coupled to the upper end of the support bar formed in a cylindrical configuration with a bend and a gripping portion and with a variable power controlling trigger and an associated trigger guard, the trigger further having a power source input in the form of an electrical receptacle; a molded plastic support handle coupled to an intermediate portion of the support bar adjacent to the lower and of the grip and having an angle adjusting nut, the support handle being adapted to allow the user to comfortably hold the system in a safe and secure manner; a molded plastic motor housing formed in a cylindrical configuration and having a bent bulbous end and a linear end coupled to the lower end of the support bar; a motor housed in the bulbous end of the motor housing with the motor having a rotatable drive shaft and a pair of braided stainless steel wires extending oppositely from each other from the drive shaft, the wires being rotatable in a primary plane parallel with a plane of grass to be mowed, the wires alternately being rotatable in a secondary plane; a molded plastic disc-shaped protective deck having a top face, a bottom face, a front, a back and a pair of sides with the top face being coupled to the bulbous end of the motor housing and the deck having a central cylindrical aperture through which the drive shaft extends, a lip around the periphery of the deck extending downwardly, a flap being comprised of an arc of the front of the deck, the flap having a pivot end, an arced end and a pair of side edges, a pair of hinges coupling the pivot end of the housing to an adjacent portion of the deck, a latch coupled to the deck and adapted to hold the flap down when operating to cut grass, the flap adapted to pivot upwardly 90 degrees to expose the wires when operating to edge soil; a pair of riding wheels coupled to the bottom face of the deck adjacent to the pivot end of the flap and adapted to ride on a top surface of grass when edging soil; a pair of guard wheels coupled to the lip of the deck adjacent to the flap and adapted to ride on a aide face of soil when edging soil; a pair of slots on the sides of the deck with a locking edge associated with each slot; a pair of stabilizing beams, each stabilizing beam having an upper end and a lower end with the upper ends being coupled to the motor housing adjacent to the lower end of the support bar and the lower ends being coupled to the sides of the deck; a pair of caster wheels, each castor wheel having an associated L-shaped flange with a horizontal portion being coupled to a castor wheel and a vertical portion with retention bumps being adapted to removably couple within the slots on the side end of the protective housing, the wheels being employed when the flap is down and grass is being cut and the wheels being removed when the flap is up and soil is being edged, the system thus having three sets of wheels, castor wheels which are rotatable about a primary axes A when cutting grass and wherein the primary axes are in a plane parallel with grass to be cut, and riding wheels rotatable about parallel secondary axes B which are perpendicular to the primary axes A, and guard wheels rotatable about parallel tertiary axes C which are perpendicular to the secondary axes; and a bag for collecting cut grass clippings, the bag having a lower end coupled to the rear end of the deck at an aperture and the bag having an upper end coupled to the support handle.
