- Hardness: 42 ± 2 HRc. (high carbon)
- Integral hardening to avoid deformations and rupture.
- The perfect balance between long service life and resistance to breakage.
- Special steel with high anti-broken characteristics
- Produce less noise
- Corrosion resistance
In this section you will find discs for disc harrow and disc tilling in a wide variety of concave forms and sizes. Firefox conducts very strict quality checks, guaranteeing that its discs for disc harrow will all be totally uniform, which means that any work you do with them will be excellent.
The right hardness ensures the ideal level of flexibility and toughness to absorb impacts without breakage, and yet at the same time to resist the most abrasive soil conditions. All this guarantees that the discs pass the toughness test known as “the ball test,” which assesses their resistance to fracture.
