Abstract

La présente invention concerne de façon générale un ensemble (10) de grattage de coutre incorporant un outil (12) de grattage de coutre qui comprend une lame rotative (18). La lame rotative (18) est en forme de plat car elle est peu profonde avec un profil relativement étroit et elle comprend un bord de travail (24) étroit. Le bord de travail (24) est configuré pour travailler avec le coutre (16) afin de gratter les excédents de matière, tels que les particules de terre et les saletés qui se sont accumulées sur le coutre (16).
