John Deere® 12-Row Knife Kit

Where does this product go?

Knives are mounted to the drum rotors, which can spin either clockwise or counter-clockwise.

How is it installed?

Always install tungsten carbide up for optimal performance.

What is this product used for?

Used for cutting forage near the bottom of the stalk. The fingers of the gathering drums feed the material into the throat of the forage harvester.

When to replace this product?

Blades should be replaced when there is no tungsten carbide hard surface left, or the rotor is out of balance.

Fits:

• Kemper 490
• John Deere® 772 Rotary Header

Kit Includes:

• 24 x KK66037LTC (Left-hand knives)
• 24 x KK66037RTC (Right-hand knives)
• 1 x KK772BK (Bolts)

Features:

• Tungsten Carbide Enhanced Knives: The knives are treated with tungsten carbide for a longer wear life, ensuring sharpness and requiring less frequent replacement. Install with the tungsten carbide facing upward for optimal performance.
• Self-Sharpening Technology: The knives wear asymmetrically, with the back side wearing faster than the hard-faced edge, creating a self-sharpening effect that maintains a consistently sharp cutting surface.
• Hard-Surfaced Blades: The hard-facing coating enhances durability, providing a longer lifespan and superior cutting efficiency for demanding agricultural work.

Note:

This kit does not include scrapers or straps. If needed, these components can be purchased separately:

• Large Drum Scraper (KK67156 / KK67157)
• Straps (KK88009)

For milled aggressive cutting knives, see KK129957 and KK129956 for better cutting in wet and weedy conditions.
