Grass Knife (John Deere®8000 Wide Body & 9000 Series)

Manufactured in Iowa, the Kooima Ag K52933 Grass Knife is designed to provide exceptional durability and precise cutting performance for John Deere® wide body 8000 and 9000 series Forage Harvesters. This heat-treated knife features a tungsten carbide hard-facing, ensuring a long service life even under heavy use and harsh conditions. Perfectly suited for chopping forage, such as hay, alfalfa, winter wheat, and cover crops, this grass knife is an essential component for maximizing your harvester's efficiency.

Key Features:

• Tungsten Carbide Hard-Faced Edge: The K52933 knife is built with a tungsten carbide edge that offers superior durability, enhancing the knife's ability to withstand wear from tough materials. This feature ensures a long-lasting, sharp edge for precise cutting.
• Precision Fit for John Deere® Forage Harvesters: Designed specifically for John Deere® Forage Harvesters, the K52933 grass knife offers a precise fit that works in conjunction with the shearbar to efficiently chop the forage into small pieces, ideal for cow consumption.
• Optimized Cutting Performance: The K52933 is designed with a less intense cutting angle compared to corn knives, allowing it to handle rocks and debris better without chipping. This makes it perfect for pickup work in hay, alfalfa, winter wheat, and cover crops.
• Installation Guidelines: For installation, use bolt K29393 or K29293HP (3 required per knife). For better performance, we recommend using the high-performance K29293HP bolt if you are experiencing rounded bolt heads. Ensure that bolts are torqued to the recommended specifications to guarantee secure installation.
• Knife Replacement: Regularly inspect the knife for signs of wear, such as heavy chips or the loss of tungsten carbide on the cutting edge. Replace the knife if you notice longer cut lengths or excessive wear to maintain optimal cutting efficiency.
• Designed for Durability: The K52933 knife is built to handle demanding conditions, providing reliable performance in your forage harvesting operations.
