Abstract: A weed cutter structure having a handle shaft with a rotary head containing at least one flexible cutter filament thereon, includes a guide assembly mounted to the handle shaft in adjacency to the cutter head, wherein the guide assembly includes a mounting bracket arranged for securement to the handle shaft, and a support bracket fixedly secured to the mounting bracket, with the support bracket having a wheel member. The guide assembly projects from a first side of the handle shaft relative to a second side of the handle shaft mounting a shield housing projection.

Abstract: An edge contouring system for removing burrs from edges of precision parts. The system includes an industrial robot for moving a special piloted deburring tool along the part edges. A compliance device applies a constant force on the deburring tool to keep it in contact with the part edge, yet permits movement of the tool in a direction normal to the part surface to accommodate for irregularities in the part geometry. A pilot integral with the deburring tool limits penetration of the tool into the part edge.
