Abstract
On décrit une lame aratoire qui comprend un ressort hélicoïdal avec un axe de ressort horizontal pour permettre une déflexion vers le haut dune lame aratoire concave en réponse à un impact avec des obstacles. Lensemble de montage assure le montage des lames aratoires dans une orientation particulière par rapport au sol et à la direction de déplacement de linstrument aratoire pour que les forces agissant sur lensemble en raison du mouvement de la lame au travers du sol soient équilibrées de sorte quil existe peu ou pas de distorsion du ressort hélicoïdal par rapport à son axe de ressort. Ceci empêche une charge hors de laxe dagir sur le ressort quand lensemble est utilisé et permet à la lame de tracer un sillon à travers le sol à un angle souhaité. Limpact avec des obstacles, comme des roches, est absorbé par la déflexion du ressort hélicoïdal, atténuant ainsi les dommages à lensemble. Les instruments aratoires comprenant les ensembles de lames peuvent fonctionner à des vitesses plus élevées que celles qui peuvent être obtenues pour les instruments aratoires, en raison de labsorption de lénergie des impacts par le ressort.
