Novel cutting heads are described for apparatus used to cut vegetation and the like. The cutting heads are each adapted to be removably affixed to a rotatable shaft and rotated about an axis generally perpendicular with a cutting plane. At least one non-metallic flexible cutting line is affixed to the novel cutting head, and ramp members are affixed to the head member which are adapted to protect the cutting line retaining means from hitting obstructions in the cutting plane.
