<p>The mulch head has a shaft for mounting with a row of flexible threads which are radially placed under the effect of the centrifugal force and a protective covering. A flexible thread (16) is spooled on a shaft (8) within a pipe (9) that is coaxially supported on a shaft. Ends of the thread extend through holes or bushes (9a) provided on the pipe and the rotation of the pipe, relative to the coaxial shaft, is influenced by a freewheel device (10), whose direction of action is reversible.</p> |
