A rotary mowing cutter (10) includes a holder (11) attached to a drive shaft, at least one cutting element (12) fixed to the holder (11) and first and second covers (13, 14) between which the cutting element (12) is arranged. The cutting element (12) includes a deformable member (12a) attached to the holder (11) and a cutter member (12b) attached to the deformable member (12a). Part of the cutter member (12b) is caused to protrude from the first and the second covers (13, 14) when the deformable member (12a) extends radially of the drive shaft. |
