The knives are standardized and made of wear-resistant steel with a hardened working zone. This design prevents blade breakage and significantly extends the service life without requiring edge sharpening. The machine is designed for shredding sunflower, soybean, and rapeseed crop residues, as well as for field surface mulching. Shredding crop residues and mulching the soil retards moisture evaporation, regulates surface layer temperature, suppresses weed growth, protects against erosion, and enriches the soil with organic matter. The "M" modification rollers feature maintenance-free FKL flanged bearing units with high-strength housings. These bearings require no maintenance, are specifically designed for operation in extremely harsh and contaminated environments, and are equipped with unique seals that extend the overall service life of the bearing assemblies
