Abstract

Un attrezzo agricolo comprendente una lama a disco che incorpora inserti duri resistenti a usura per attacco a un organo assiale di un attrezzo agricolo, per rotazione attraverso il terreno. La lama a disco comprende superfici parallele anteriore e posteriore distanziate, piatte, rotonde aventi un'apertura cilindrica centrale. La superficie anteriore è rastremata radialmente verso l'esterno verso la superficie posteriore definendo così un margine esterno comune avente un bordo a coltello. Una pluralità di incavi sono distanziati circonferenzialmente lungo la superficie anteriore della lama a disco e verso l'interno dal bordo esterno della superficie anteriore della lama a disco. Gli incavi sono configurati per accogliere una pluralità di inserti duri, resistenti a usura, per fornire una miglior resistenza a usura.
