An apparatus, such as an edger, trimmer or lawnmower, for cutting vegetation using a flexible non-metallic line member extending into a cutting plane from a rotating head (e.g., U.S. Pat. Nos. 3,708,967, 3,826,068; 3,859,776). At the user's signal during cutting, the line member is fed to a certain discrete length (2 inches) from the rotating head under direct mechanical control (no free wheeling). Then the line member is automatically relocked within the head.
