Publication number: 20080168756Abstract: This apparatus is a cutting assembly commonly used as a trimmer with a mower deck combination but not limited to such a combination. This trimmer head assembly utilizes a high lift mower blade in combination with a string or line trimming blade in a housing which creates a vortex of air which draws grass and weeds toward the assembly where they may be cut with the rotating line. By drawing grass and weeds towards the assembly and away from obstructions this cutting assembly results in a closer cut than may be achieved with a conventional trimmer. Because grass and weeds are drawn away from obstructions and cut, the trimming string does not make contact with obstructions and therefore causes no damage to objects such as gravestones, fences, etc. This cutting assembly may be adapted for use on a variety of lawn and grounds keeping equipment such as hand held string trimmers, walk behind trimmers, or in place of a normal mowing assemblies on riding or push lawnmowers.Type: ApplicationFiled: March 17, 2008Publication date: July 17, 2008Inventor: Dean Nafziger
