Abstract

La présente invention concerne un outil agricole (1) pour travailler le sol, l'outil comprenant une première partie (30, 31, 32) et un dispositif capteur (2). Le dispositif capteur comprend un capteur sans contact (10) disposé sur ladite première partie et conçu pour mesurer une distance par rapport à au moins un objet de mesure (40, 41, 42) au moyen d'un rayonnement (12). Ledit objet de mesure est une seconde partie (42) de l'outil agricole ou le sol (41) avant, pendant ou après le travail du sol. Ledit dispositif capteur (2) comprend en outre un réflecteur (20, 21) disposé entre ledit capteur (10) et l'objet de mesure dans la direction de mesure du rayonnement, de sorte que ledit rayonnement (12) change sa direction du capteur à l'objet de mesure au moyen du réflecteur. La présente invention concerne en outre un procédé (200) de mesure de distance.
