A grass and weed trimmer head is provided having a trimmer head body wherein the outside surface has a dome-like contour with the drive shaft of the trimmer centrally fixed to the top of the dome. The bottom of the body is a circular opening having an inside diameter large enough to accommodate the outside diameter of a rotatable bottom plate so as to allow sufficient clearance to permit free rotation of the bottom plate while providing insufficient clearance for debris to enter the clearance. The rotatable bottom plate is disposed in a manner so as to redirect cutting debris away from the crevasses in the trimmer. The dome-like contour encourages the redirection of the cutting debris outwards and away from the central shaft thereby significantly reducing the propensity of wrapping and clumping around the central shaft. Easy removal of the cutting strings aids disentanglement of cuttings from the trimmer.
