<p>A ploughshare (10) having cutting edges (2) and securing means (4, 5) for attachment to a plough (not shown). The ploughshare (10) has a number of individual metallic shares (6) which are firmly embedded in an elastomer mass (3). During use, each individual share (6) is independently moveable from the underlying surface against the elasticity in the mass (3) with a view to absorbing or adjusting itself to irregularities (wheel track wear) in the underlying surface. The share is mounted substantially vertical and is especially designed for equipment for clearing snow, slush and ice.</p> |
