<p>The invention relates to a discer system. Said system is characterised in that each ploughing disc (7) comprises a cup (9) at the centre of the concave part thereof, said cup being fixed to the disc (7) coaxially to the rotational axis thereof (A-A'), and enabling the earth hitting the cup (9), which rotates with the disc (7) working the ground during the displacement of the discer, to be pulverised, in such a way as to prevent the formation of ploughing tongues that can adhere to the internal concave face of the disc (7). The invention applies to the field of agriculture.</p> |
