Role in the grinding system

Kuhn professional shredders often use a combined knife arrangement. The knife J1551147 is installed midway between two side knives (e.g. J2555004) on the same mounting bolt:

1. Stalk splitting: While the side Y-knives cut and lift the mass, the central knife J1551147 splits coarse stalks (corn, sunflower) along the fibers.

2. Preventing "dead zones": It covers the space between the side blades, ensuring that no part of the crop remains intact.

3. Improved mulching: Thanks to it, plant residues are converted into organic fertilizer faster, as they have a larger area of damage for soil microbiota to access.

Key benefits

• High impact strength: The knife is designed not to break when it encounters stones, but only to slightly deform or wear down.

• Reducing the load on the rotor: Using a central knife allows you to achieve high quality chopping without the need to lower the entire unit as low to the ground as possible.

• Wear resistance: Original Kuhn steel has high surface hardness, which is critical when working on sandy or dry soils.
