System for a mulcher

A system (10) for a mulcher comprising:

• a rotor (11) rotating about a rotation axis (A) in an operating direction (R) and having a substantially cylindrical outer surface (12),
• a plurality of tools (20;
• 40),
• connecting means for connecting the tools (20;
• 40) to the rotor (11), configured to fixedly connect the tools (20;
• 40) to the rotor (11),
• wherein said connecting means comprise, for each tool (20;
• 40), a respective tool holder (60) having a base portion (61), configured to be fixedly mounted on said outer surface (12) of said rotor (11), and a mounting portion (64), configured to allow the tool (20;
• 40) to be fixedly mounted on the tool holder (60),
• wherein each of said tools (20;
• 40) comprises a first blade (21;
• 41) arranged in a front upper portion (22;
• 42) of the tool and having a cutting edge (21a;
• 41a) extending substantially parallel to the rotation axis (A) of the rotor (11) and directed towards said operating direction (R),
• characterized in that each of said tools (20;
• 40) comprises a second blade (23;
• 43) arranged in a front lower portion (24;
• 44) of the tool and comprising two faces (23b, 23c;
• 43b, 43c) angled to each other which join to form a second cutting edge (23a;
• 43a), said second cutting edge (23a;
• 43a) extending transversely with respect to the outer surface (12) of the rotor (11) and being positioned centrally with respect to the first cutting edge (21a;
• 41a) of the first blade (21;
• 41).
