12-Row Knife Kit
Kooima Ag #KK772TC
This knife kit is used to replace all of the knives and bolts on a John Deere® 772 rotary header. These knives are used to cut silage and other feed.
The knives in this kit are treated with tungsten carbide, giving them a longer wear life. These should be installed with the tungsten carbide facing up.
The knives should be replaced when the teeth start to get rounded instead of holding a strong, sharp point. Typically, when there is a 1/4" or less of tungsten carbide left on the leading edge.
Hard-Surfaced Blades with Tungsten Carbide Edge:
- Advanced Coating Technology:
- These blades feature a hard-facing coating coupled with a wear-sharp surface.
- The hard-faced side boasts exceptional durability, prolonging the blade's lifespan.
- Self-Sharpening Advantage:
- Uniquely designed to wear asymmetrically—the back side wears faster than the hard-faced side.
- As it wears, the backside gradually forms a sharp edge, effectively self-sharpening during use.
- Tungsten Carbide Enhancement:
- Embedded with tungsten hard-facing for added resilience and longevity.
- This tungsten edge ensures consistent sharpness, enhancing cutting efficiency.
- High Popularity:
- Widely acclaimed and highly sought-after due to its self-sharpening feature and extended lifespan.
These hard-surfaced blades epitomize innovation, utilizing advanced coating technology and a self-sharpening mechanism. The combination of hard-facing and tungsten enhancements ensures prolonged durability and consistent cutting performance, making them a popular choice among users seeking longevity and self-maintenance in their replacement blades.
