Patent
CA 2284703
A disc coulter (2) reciprocates vertically (e.g., by having its centre offset by 2 mm from its axle) and horizontally (e.g., by a tilt of 0.25~). The vibration resulting from the rolling of the coulter over the ground (or by the disc being given a reverse rotation hydraulically) improves its cutting through soil and trash. The latter also tends to be guillotined between the disc and a closely placed following boot (23). This boot has two straight channels which result in vertical spacing of seed and fertiliser in the soil. The toe of the boot sits higher than the disc to ensure its riding over obstacles.
Cette invention concerne des améliorations apportées à des dispositifs de travail du sol par le fait que l'on confère un mouvement vertical et latéral à des lames de coupe du sol. Certains aspects de la présente invention comprennent des modifications apportées également à des sabots.
