ABSTRACT:
A cutting head for a nylon-cord mower and the like, comprising a case housing an inner spool on which it is wound at least a length of nylon cord, elastically loaded by a helical spring, with the two ends of said nylon cord protruding through pairs of annular members mounted on said case in diametrally opposed locations. The inner spool is formed by a cylindrical body with at least two holes aligned along an axis intersecting the axis of the spool, and that can be axially aligned with the two annular members for allowing the replacement of the nylon cord without opening the cutting head.
