1. A detachable ploughshare tip having two cutting edges (1c, 1d) adapted to be obliquely mounted on the forward end of a ploughshare (3) and capable of being fixed thereon in two positions mutually offset by 1808, characterised by the fact that it has on each of its edges and symmetrically with respect to its centre, a bulge (1a, 1b) which extends, and becomes thicker, from the respective cutting edge (1c, 1d) as far as about the middle of the edge of the tip and has a surface forming a transition between the upper flat surface of the tip and its lower, surface, thus attenuating the effect of the additional thickness on the ploughshare (3) and laterally protecting the plough sole (4) in order to obtain slower and more even wear. |
