Build & Design
This disc has a large, smooth concave design, made for soil turning, cutting, and mixing. The 660 mm diameter gives it strong working depth potential, while the 6 mm thickness provides durability for heavy-duty cultivation.
The Square 41 mounting is an important detail, as it must match the shaft or hub system of the machine. The black coated finish helps protect the disc during storage and initial use.
Performance
The disc is designed to:
- Cut and loosen the soil effectively
- Mix crop residues into the soil
- Maintain stable operation in heavy field conditions

- Restore working depth and cultivation quality
Because of its large size and thick construction, it is suitable for more demanding soil conditions than lighter discs.
