Product Description

Hammer Blades RM 11 are engineered for superior performance in flail mowers, mulchers, shredders, and agricultural cutting equipment. Manufactured using high-grade 27MnB5 / 30MnB5 boron alloy steel, these blades deliver outstanding tensile strength, shock resistance, and long service life.

Each blade undergoes controlled heat treatment to achieve a hardness of 42–45 HRC, ensuring excellent resistance to abrasion and impact during operation. The precision-formed cutting profile supports efficient chopping of grass, crop residue, branches, and other biomass.

Finished in a Self & Oiled protective coating, the RM 11 hammer blades remain corrosion-resistant and ready for long-term field use. With multiple hole size options (16.5mm, 18.5mm, and 20.5mm), they fit a wide range of flail mower models and rotary mulchers with ease.

Built for durability and reliability, these blades ensure smooth operation, reduced downtime, and optimized cutting efficiency.
