DURABILITY AND STRENGTH
All Case IH Heavy-Offset 790 disk harrows are equipped with Earth Metal® blades. Uniquely formed and heat treated, Earth Metal blades offer exceptional endurance and break resistance for longer equipment life. The notched blades aggressively cut residue and vegetation with excellent cut uniformity. |
Long-Life Durability
Compared to conventional blades under identical conditions, Earth Metal blades: - Are 30% stronger
- Last up to 20% longer
- Resist stress fractures
- Feature shallow-concavity design
- Easier to pull than conical or spherical blades
- Promote better fuel economy
|
Self-Sharpening
Earth Metal blades actually resharpen as they wear. - Provides superior cutting performance over an extended blade life
- Helps prevent down time and maintenance labor
- Lowers blade replacement cost
The performance of Earth Metal blades actually improves as they are used, while conventional blades lose their sharpness with wear. |
